Hull 923 Harness The Sun-Solar Panels
My wife, Anna, and I enjoyed cruising our Catalina 320 to But which panels should I get,
how many watts do I need, where should I mount them? The last question was easy. Our boat was ordered with the factory hard
dodger, which affords us 84” X 40” of usable space to mount solar panels
permanently. I chose to mount three
Kyocera KC85T solar panels as they fit perfectly requiring a space of 77” X
39.6” and generated about approximately 1,275 watts a day. I estimated that my power needs for lights,
stereo and refrigeration would be between 800 to 1,150 watts a day.
I
solved the problem of legs by cutting 18 from a teak board.
The dimensions are as noted on the illustration.
One side of the height is shorter by 1/16” to
compensate for the curvature of the dodger. A hole was centered and bored
through the height and tapped with a ¼” - 20 tap. Six legs were then
temporarily mounted to each panel with cheap ¼”
X ¾” bolts. The bolts were
tightened only enough to hold the legs steady.
Place all three panels atop the dodger and arrange them
where you want them.
Each panel’s junction box
should face forward. If a leg needs
to be lengthened/shortened, make adjustments
to the leg or make a new leg.
Carefully pencil the circumference of each leg’s
footprint on the dodger. Drill the
necessary holes through each footprint.
Each
leg must be permanently mounted in its original location on the panel.
Perform this installation one leg at a time. Begin by unscrewing the leg and removing the
bolt from the panel. Thread a 3 ¾”
stainless steel stud through the leg.
Screwing a cap nut on the stud will make this process easier. The length of stud left protruding from the
bottom of each leg should equal the thickness of the hard dodger (approximately
7/8”) plus the height of the washer and lock nut. Slip the top of the stud and leg through the
mounting hole in the panel. Fasten the leg
with a washer and locknut. You may need to
keep the stud from spinning by holding it with vice grips. The threads in the leg will hold the stud and
allow the lock nut to be tightened.
Note: over tightening will strip
out the threads in the leg. Be sure that
the taller side of each leg faces the outside of the length each panel.
Connect 60” or more of 10 AWG cable to the starboard panel’s junction box.
Connect 30” or more of 10 AWG cable to the center solar panel’s junction
box. Connect about 18” of cable to the
port side solar panel. Install the
starboard side and center solar panels onto the hard dodger with washers and
locknuts. Drill a hold through the dodger
and dog house to pass the 8 AWG cable that will run
from the splice at the panels to the controller (see pictures). Tread the 8 AWG cable up through the dog house
then through the dodger. If you are using
waterproofing plates around the 8 AWG cable, be sure to feed them through on the
correct side of the dog house and dodger. Waterproof the splice that connects the three
panel cables to the 8 AWG cable.
Permanently mount the port side solar panel with washers and locknuts. Tie the cable to the stainless frame of the
dodger.
Follow the instructions from Blue Sky for mounting
an SB-2000E Solar Boost Controller. Locate it where it
will be easy to view and gain rear access.
Run the 8 AWG cable to the controller and then to
the batteries. A 30 amp
fuse or circuit breaker should be wired to the
positive cable close to the batteries.

There
were three challenges involved in installing the
panels. The panels
needed legs to raise the edges to allow clearance
over the curving dodger and clearance for each panel’s
junction box which was lower than the sides of the
aluminum panels. The mounting bolts
would have to be over 3” long and could not be
installed to the panels from below or above.
The lock nuts to mount each panel would have to be
installed from below on a bolt with just enough length
to lock the nut.
You
will need 18 studs all 3¾” long X ¼” – 20.
These can be fabricated from two pieces of 3 foot long ¼” – 20 marine grade
stainless steel rod. 3¾” lengths can be snapped off the rod.

Camelot (sistership to
Ursa Minor #178)
By Nick Wigen
Camelot and Ursa Minor are identical fin keel, 3-cabin MkI boats built in 1990 that share adjacent slips in Portland, Oregon. A couple of years ago Bob Teeter upgraded his rudder to the newer elliptical design while Ursa Minor is still blessed with the old barn door slab. The new rudder has beneficial effects on boat handling but any improvement in boat speed is small enough to get lost in variations in sail trim, luck and sailor attention. We’ve found when racing head to head we both generally lose about the same number of causal races. Our plan for Ursa Minor is to upgrade the rudder fairly soon.
Camelot’s rudder sat in Bob’s garage gathering dust and getting in the way. Recently the planets lined up just right where I had my utility trailer at the moorage and he wanted to get rid of the old rudder. There may have been beer involved… Anyway, I ended up with the rudder in my carport with a vague idea of stripping off the fiberglass, reinforcing the stock and building a new rudder. Here is a story of those events.
Conclusions: The general method of forming the shell and injecting the resin/fiber mix appeared to provide a solid structure. Two things do concern me about the way this rudder was built. The use of plain carbon steel below the waterline seems to be foolish economy. Camelot has spent all but a few months in fresh water. It would be interesting to see what a rudder with full-time saltwater immersion would look like. The other concern is the compete lack of bracing or reinforcement against the torque transmitted to the rudder which is carried only by the single plate. My company uses heavy duty air control dampers in our equipment and we have seen failures of the weld between the blade and shaft when this method is used. We would never accept this configuration. Before buying a replacement rudder from Catalina I would need proof that they have changed to a proper design.

Battery & Charger Improvements

At the core of this scheme is an adequate house bank of batteries. The three 4Ds that came with a 1994 model 2-cabin would probably suffice, but with one of the batteries near the mast, some change was needed. The run from the lazarette behind the galley to the mast seemed a bit long for any charger to overcome. Our original Freedom 1800 forced the decision by sacrificing itself to save its fuse. |
![]() |
The first step was to decide on 6V deep-cycle
golf cart batteries. Individually they are much easier to move than a
single 4D. They are also much more readily available outside of the US
(we've been told and have observed in Mexico). This also increased our
Amp-hour capacity from around 550 to 660. More Amp hours could be had from
taller 6-volts (they are 1.5 inch taller and may be the replacements for
these ... 1100 Ah in the same space!). Fillers were built from 2x4
material which hold down the 4 batteries in the back in the standard
battery compartment. A standard 4D battery case fit in the space between
the existing battery compartment and the door to the galley. It has its
own frame bolted to the floor and the new forward wall which itself is
bolted to the existing bulkhead. All covers are bolted down, bolted to the
surfaces available which in turn are bolted to the pan. The batteries
should stay in place on all angles of heel.
|
![]() |
We decided to go with a Freedom 30
inverter/charger on the theory that when at the fuel dock for a short
time, it could do a lot of charging in the time available. (We want to
avoid marinas as much as possible.) We've found that the modified sine
wave AC output has been no problem for any of our equipment including
battery chargers and computer. It is mounted on the shelf running along
the outside port hull in the aft lazarette. The shelf required some
reinforcement along the back edge to support the added weight (56 pounds).
|
![]() |
The Freedom and Link 1000 documentation are
quite good when it comes to installation requirements and schematics. But
not perfect ... see the
bulletin board
posting for additional learnings. Because there was one run of cable over
6 feet, 0000 (4x0) cable was required through all paths that the charger
would follow. Wiring to the distribution panel and other takeoffs remained
the same but upgrades are part of the long-term plan. The Freedom can put
out 140 Amps DC when charging (we've seen 130 on the Link 1000 display)
and 3000 watts when inverting (a 250 Amp draw from the batteries). Freedom
documentation indicates a dedicated battery switch (at the top right in
the photo) and a 350 Amp fuse (below the shelf on the right). Both are
mounted on the galley bulkhead. The cranking battery is in the black case
at the bottom mounted to the existing shelf. It is fed by the 'Echo
Charge' feature of the larger Freedom inverter/chargers and not treated as
a separate battery bank by the Link 1000 controller. The house and
cranking battery switches are mounted to the pan along the port hull. In
the event of a cranking battery failure, we plan to jump the house and
cranking battery with jumper cables (golf cart batteries can take it with
no damage).
|
![]() |
Correct operation of the Link 1000
monitor/controller required moving all the connections normally run to the
battery bank to outside the actual bank itself. This photo shows the Link
1000 shunt on the left with the battery bank connection coming in at the
bottom. It is located on the back of the battery compartment. The
connections for the charger and all downstream loads are at the top of the
shunt. All other connections are then made to the heavy-duty buss bar
downline from the shunt. The smaller wires are the Link 1000 monitoring
and power wires.
|
![]() |
While not explained in the documentation, the
same principle must be applied to the positive side. This buss bar is
inside a compartment on the port side of the battery compartment. The wire
coming in from the left in the photo is the only positive connection to
the battery bank. The small wires are again Link 1000 connections. The
smallish wire coming in to the second post is from the alternator (soon to
be upsized), The third wire is from the Freedom 30 and the fourth wire
leads to another buss which feeds all other connections. Eventually solar
and wind power will be connected to this buss. In this fashion, the Link
and Freedom can monitor all charging activity, not only their own.
|
![]() |
This schematic is basically a redrawing of
one of the options shown in the Freedom documentation. Because all AC
power is run through the Freedom before going to other AC circuit
breakers, we have to manually turn off the water heater when charging or
inverting. The AC could be rewired so that the water heater is on another
circuit and automatically turned off when shore power is severed. But our
decision to go as a 'green' boat means that once away from the dock, only
the engine will heat water (or SunShower) and the water heater AC breaker
will be left off. One important consideration is the addition of a
galvanic isolator where the shore power first enters the boat. The
inverter/charger mixes AC and DC grounds to do its job and for safety.
This could lead to catastrophic galvanic corrosion without the galvanic
isolator.

Improvements
By Norm Perron
Once we took delivery of Aphrodisiac, our new Catalina 42 (August 97), the never ending job of modifying & improving her began. Some of these changes are predicated on a 2-cabin, but a 3-cabin and other Catalina owners will see how some of these ideas could be applied to their yacht.
Lets get to the photos. Click on them for an expanded view.

Phase 2 of Hull 600 improvements

Since there have been some failures of the single shackle mainsheet blocks attachment to the traveler, I decided to go with the upgraded car & 3 @ 3" Garhauer Unibody blocks. Beautiful, aren't they? The new car was compatible with the traveler on hull 600. The new car is shipped on a short piece of track with the ball-bearings in place. To install the new car, you need to slide the old car off (may want to capture most of the ball-bearings). Then line up the small track that was shipped with the traveler and transfer the new car to the traveler, being sure no balls fall out. It may sound messy, but very easy to do the transfer. The triple blocks on the ends of the traveler come with the kit & need to be swapped out (so they match the blocks on the movable car). Besides, one needs to be removed to swap the cars. |
![]() |
On the boom is a 3" double Unibody block (forward). And a 4" single Unibody block with a becket. Garhauer recommended the 4" aft as a larger wheel is more efficient. |
![]() |
On the traveler ends, I took off the cam-cleat & put a Harken bale instead. Then inside the dodger, ran the traveler control line through a spare sheet stopper & labeled all stoppers. There was a spare stopper on the starboard side. Needed to install a new one on the port side. This way, the traveler can be adjusted easily from inside the dodger. |
![]() |
Here is a poor sketch (wish I had
time to draw it on the computer, but this was quite faster) of the original
& new jiffy reefing system. The top half is the system hull 600 came with,
with the butterfly block in the boom. The butterfly block came out of the
aft of the boom quite easily. You will notice the old system had 3 extra
blocks, more friction. I don't see any advantage with the old system, if
anybody does, please let me know.
The only possible issue in anyone else retrofitting to the new system is there must be a slot above the 4 blocks near the gooseneck so the line can go up to the cringle in the sail. The guys at Charleston Spar volunteered to mill out that slot for me if I need it milled as they made some without that slot. Luckily I didn't need it milled as I didn't want to remove the boom from the end piece. |
![]() |
I've been concerned about the main electrical fresh water pump failing when on a trip. There is no easy to extract fresh water from the stock tanks. I installed a small foot pump in the coaming compartment under the oven. It is fed from the water manifold under the sink, with a valve in-line. A new basic spout needed to be installed next to the main faucet. |
![]() |
I found this great stainless soap dispenser in one of the stores in Annapolis ( http://www.eurostyleimports.com/ currently on the 3rd page of Bath). The fact it screws to the wall makes it very functional. |
![]() |
There has been some discussion on where to mount an inverter (remember, 2-cabin). Putting it just inside the "garage" door makes it very visible and allows the wires to be very short. While I was at it, the stock battery charger was re-mounted so the amp meter can be seen. |
![]() |
I made a small padlock holster and mounted it just where you need it, in reaching distance when closing up the bin boards. This also turned out to be an attractive location to mount the Number Board. |
![]() |
We have never used the hanging portion of the aft cabin closet. We're always looking for places to store stuff, so these shelves seem to tie both these conditions together. They can easily be removed and the pole re-inserted if need be. |
![]() |
Garhauer Marine has an option of longer turnbuckle covers. They are beautiful & cover the entire turnbuckle. You see the delrin is tapered on the top with set-screws so they don't pop out. The hole where the shroud goes thru is very-very tight (and split so the wire can go thru), minimizing the water that will enter the cover. It is quite a job installing them as each shroud needs to be disconnected, one at a time. |
![]() |
I like to hose down the dink at the islands when done. I installed a 15' coiled hose in the anchor well on the starboard side. Running the hose to the forward sink wasn't too tough, no hoses visible. A valve was installed under the sink to be sure the pump doesn't cycle a lot due to a leaking nozzle. There is plenty of pressure, even at this head, with the stock pump. If you get one of these hoses, be sure to get the version that is setup with a "thru-hull" brass fitting with a friction fitting inside the boat. The 1st one I bought had a standard hose fitting which did not work as well. |
![]() |
This is my latest gimmick: a guard
that goes over the axel on the Edson pedestal. We take the wheel off all
the time while on a mooring or anchor. I've always been concerned in
losing the key (I do have a spare, though) or allowing someone to touch
the axel and get full of grease as this is always lubricated.
As you an see it is made of 2 different size PVC pipes glued together. The inside pipe has an oversize notch so the key stays retained. Of course, the nut goes back on. |
![]() |
When I had a Catalina 36 with a Harken jib furling drum, they said it is not under warranty unless there is a ratcheting block. When the C42 was being commissioned, I installed one of these on the bales at the base of a stanchion. On the 42, I wanted to get this block as far away as any persons foot to minimize tripping. Since Garhauer makes sliders, they made this custom slider, specifically for this block. This ratcheting arrangement works great when pulling in the jib. If you pull from an angel, it holds the line a bit allowing you to rest between pulls. I know some sailors use their winches for this task, but I personally don't like that idea. |
![]() |
You can buy some SOLAS reflective tape that's about 2" wide (at West
Marine). I've applied some on the tops of 4 stanchions. This makes it much
easier to find your boat in a crowded area at night. Just point a
flashlight & it stands out quite well.
OK, I haven't really needed it much, but it sure looks cool at night. |
![]() |
This kayak holder is not actually on Aphrodisiac. A dock neighbor, Captain Rick, had Garhauer Marine make a few for his kayak. Rick says it has worked out very well. |
![]() |
I know this is a pretty ugly photo. It is where I mounted a SHURFLO water filter, just above the fresh water pump. I decided to filter all fresh water in an effort to keep the aerators clean on all spigots, which has worked out quite well. At the same time, I got rid of the noisy belt driven pump & installed a new ITT Jabsco VSD (Variable Speed) pump. This pump is great. Extremely quiet. Since it is variable speed, it turns very slow when a faucet is on very low. Can't hear it & very smooth water flow. |
![]() |
My wife wanted a TV in the pullman area so we went with a Samsung 17" TV/monitor. A 1/4" thick aluminum plate is fastened to the 4 counter-sunk mounting screws that attach to the TV in the back. Coming out the other side of this plate are 2 @ 1/4" screws that go thru the wood bulkhead. The TV comes down easily by removing 2 nuts (and 2 locking crown nuts) just above the toilet. You can see a small DVD player is on the shelf, wired to this TV. |
![]() |
I know everyone has their favorite decoration on the forward wall in the mail salon. I just want to share with you what my Kinkade painting looks like. It is difficult to see, but there are actually 3 frames around it, It is Velcro up, so I may take it with me if ever sell the boat. |

Instead of taking the US flag down
at sunset, why not light it up. Now with white led flashlights, power
consumption is not that big of a deal. The flashlights I used have 7 led's.
In hindsight, 7 is not needed, especially if you use 2 flashlights. They are
powered by rechargeable nimh cells. The mounts (right side of the photo) use
1" clamps, designed to clamp on a vertical stanchion or pulpit and the
up/down angle is adjustable by loosening/tightening a nut.
|
![]() |
I like to take photos while
sailing. I find tripods don't work, so devised a clamp with a long 1/4"
screw onto which the camera is mounted. One of my favorite shots is of the
subject sitting on the starboard observation seat. The clamp is mounted on
the starboard aft gate stanchion, facing aft. All of us get in the photo,
with the flag in the background. Then I email the guests the best shot taken
with the self timer. The shot on the right shows a bit more detail of the screw going thru the clamp with a wing nut to lock the camera in place. |
![]() |
I finally got around to replacing
the original (over 8 year old) Catalina supplied 4D battery (closest to the
windlass, remember hull 600, 2-cabin). I much prefer golf cart batteries, so
went with them. Height was no problem, but the bank is about 1/2" longer
than the 4D. I needed to cut off the outboard side of the battery box.
Fairly big job, did it with jig saw & belt sander to smooth the edges. Then
needed to bond a piece of hard wood on the outboard side, so the batteries
couldn't shift around when heeling. The shroud around them needed a bit of
trimming to clear this block of wood. I needed to re-locate the 2x2 wood on
top, no big deal. Cover fits fine. All in all, glad I did it. Wires were not a problem at all, just long enough. |

Adding Diesel Capacity
By Dan Smith
The system is designed to have three (3) storage tanks:
#1 forward port, 48 gal;
#2 starboard aft, 36.5 gal;
#3 port aft, 52 gal;
and a 17 gal service tank centerline aft.
Fuel Levels:
Fuel quantity for the storage tank is read on the main fuel gage on the instrument cluster. Press the RED button for the tank that you wish to monitor and it will indicate that tank's fuel level. The fuel level for the service tank is read from the gage under the port aft transom seat and requires no switch, as it reads directly from the tank at all times.
Fuel Vents:
The storage tanks each have vents, but no fuel return line. Only the service tank has a fuel return. The vents for the service tank and tank #3 are shared. The vent for tank #1 is forward on the hull next to the forward holding tank vent.
To Fill A Tank From An Outside Source:
Fuel is filled from three (3) deck ports located next to their respective tank except the service tank which is filled via an electric (12 VDC) rotary vane transfer pump. The controls for this pump and the fuel system are located in the engine room. All fuel from foreign ports is to be filled through a BAJA filter-without exception.
Fuel Additive:
All fuel needs to have fuel additive, PRI and Algaecide added according to the ratio on the additive. This is critical to maintain clean fresh fuel. Log it. Use a ratio of 2000:1. Additive is to be mixed with added fuel WHILE filling, NOT added after or before filling, as it will not mix properly.
Tank Use Order:
In order to maintain boat weight balance (CG) the tanks should be pumped in the following order: #3, #2, #1. Transfer pumping is to be done when the service tank reaches ¼ tank reading (which should occur after fourteen (14) hours of use at 1 to .65 GPH at 2200 rpm).
Fuel Filter System:
The fuel from the service tank has been filtered
when filling (by the service tank fill line
filter) and feeds through a main fuel control valve to
the A and B filters. These filters can be used in pairs or single. The B filter
is the main feed filter and has separate intake and discharge valves (as
does the A filter). In a fuel stoppage in the B filter, open the A filter
valves (2) and close and clean the B filter unit. The filters are of RACOR
type and have sediment bowl and drain for observation. The top T handle
gives access to a secondary element filter. Flood the filter with fuel
with the T slightly loose so that air can bleed out, then tighten properly.
Special Operations:
It is possible to supply the main fuel filters and engine directly and bypass the service tank, pumping directly from a supply tank. To do this, open the fuel bypass valve located next to and above the main fuel control valve, and engage fuel transfer pump. Do not open the fuel fill valve. This may also be done to flood the fuel filters after maintenance or cleaning.
Fuel Log:
A fuel log should be maintained and posted on the
door of the engine room to record all fuel related operations, from receiving
outside fuel to transfer pumping and fuel
additives. This log is critical to monitoring the fuel
system and maintaining clean, reliable fuel.
The service tank is to be kept at maximum fill at
all times that the boat is secured or
underway for both security of the system and reliability of an
available good fuel supply.
To Transfer Fuel From A Storage Tank To The Service Tank:
1. Check fuel level in service tank.
2. Check fuel levels in storage and determine which of the three
tanks you will pump from. Cross check the
fuel log to see from which tank the last
transfer was made.
3. In engine room, open the tank valve for the specific tank
selected.
4. Open the tank fill valve. This is a dual function as both fill
and fuel return line and is only opened to
fill the service tank after which it is
closed to allow fuel return to the service tank from the engine.
5. Start electric transfer pump labeled FUEL PUMP CONTROL SWITCH by
lifting the switch.
6. Have someone topside monitor the service tank gage and vent (port
aft).
7. Monitor fuel flow through the filter and check for dirt and water
in the bowl.
8. When full, CLOSE tank fill valve first and the valve from the
tank pumped from before you disengage
transfer pump. This prevents any siphon by
the fuel return line from happening and putting an air lock in
the transfer pump line.
9. Check level in supply tank.
10. Update the fuel log with what you did and when.
Keep the service tank at maximum fill at all times to prevent fuel contamination.
Emergency Fuel Transfer:
There are two (2) fuel transfer line disconnects:
one before transfer pump, but after the
filter; and another after the transfer pump discharge. These disconnects
allow a ¾" hose to be connected for a manual transfer pump (Granger
barrel pump with garden hose) for situations when the electric transfer
pump fails.
System design: Dan Smith
System installation: American Tank
All tanks are 6061-t6 alloy Aluminum with welded seams and internal baffles.

Preparing
Moonspun for Passage November 1998
Jim & Cindi Goodrich
With a convenient point to pause in our careers and with the kids off to college, Cindi and I have decided to take the plunge. Beginning in January, we'll be off to Mexico, Central America, and the South Pacific aboard Moonspun (hull #101, three-cabin, fin keel model). We're selling the house, cars, and furniture, and giving the dogs to some friends. Then the realization struck us...we have to fix up the house for sale and get Moonspun passage ready...in a hurry. We decided to divide the labor. Cindi will be in charge of the house and I'll be in charge of the boat.
I attacked my half of the work with a passion. The first thing I did was to make a spreadsheet containing all the things we might want to do to get Moonspun ready (sorry, it's the engineer in me). The wish list was $60,000 long!!! Choke!!! Time to divide the list into "needs" and "wants". Fortunately, the local West Marine store manager will be giving us some good discounts.
First in our priorities was increasing the fuel capacity of the boat from 38 gallons to (ideally) 200 gallons. Increasing fuel capacity will allow us to range farther afield, while enjoying the energy-hunger conveniences such as a watermaker, modern electronics (radar, computer, SSB radio, etc.) and freezer.
We started with an obvious project to increase fuel capacity. We removed the holding tank from the starboard quarterberth, filled in the through-hull fitting and removed the macerator pump. Using the holding tank as a template, our tank fabricator expanded its dimensions aft so that the new aluminum fuel tank filled in the compartment, complete with a curved bottom (Figure 1). This gave us a tank with a 36-gallon capacity. If we had expanded the tank's dimensions outboard, we could have added another 4 gallons but we wanted to leave room for future hose and wire runs, if needed. The fill hose was run to the starboard rail near the other fill fitting. We ran the vent hose aft to the abandoned holding tank vent (make sure you replace the through-hull fitting or you'll get a big surprise when you try to fill the tank the first time). Three-way valves were added in the engine room between the tanks and the Racor fuel filter for the fuel feed and return lines. An electric fuel gauge was added to the bulkhead forward of the existing fuel tank (see lower left in Figure 1).
We fabricated a new 22-gallon holding tank that was made from high density, half-inch wall, heat-welded polypropylene. This tank is located in the bilge between the dustbin at the base of the companionway and the shower drain in the aft head (see Figure 2). To install the tank, we cut the cabin sole and dropped the tank in place. We needed to loosen wire connections so that the tank could be slipped beneath the wires that run in a race along the roof of the bilge. We also had to cut a huge piece of fiberglass out that held the shower drain in place; the drain was re-plumbed. The tank was secured inboard with a wide wooden plank that was screwed to wooden cleats in the bilge stringers.
The fiberglass cabin sole that was removed for installation was glued and screwed to the wooden sole, was then screwed into place to finish the opening. The macerator pump was moved to the bilge stringer aft of the dustbin, and the through-hull was added in the space immediately to port of the dustbin. The vent line was run up the back of the hanging locker in the starboard quarterberth. The vent through-hull was a little lower than I wanted, so I added an in-line check valve between the top of the hose loop and the through-hull fitting to keep water from flowing into the tank on port tack. The pumpout hose was run behind the medicine cabinet in the aft head to the deck.
While the boat was out of the water to remove and add through-hull fittings for the aft holding tank, we added the transducer for the Interface Twin Scope sonar system. (I should get back the 3 seconds per mile in PHRF that I lost for adding the new rudder because of the transducer's size). This system can see out about 1200 feet in front of the boat in open water and is alarmed to alert us if anything "pops up" in front of us. It should relieve some of the anxiety of having a deep fin keel and long rudder around reefs and coral heads.
For night sailing, we added stainless steel red cabin lights (West Marine) in each stateroom and the main salon. Some of these lights are two-way (white and red). Most of the new lights replaced the plastic fixtures originally supplied by Catalina (the plastic was becoming brittle and breaking).
To add a little comfort, we installed the updated stern rail that is standard equipment on the Mark II models and the later Mark Is. Conveniently, the company that makes rails for Catalina, Railmakers, is located close by. The rail fits exactly into the existing mounting holes; however, the new rail comes with an additional mounting post that needs to be drilled. While replacing the rail, we discovered that Catalina does not use backing plates for the stern rail mounting hardware, so we added them. We found that the only modification that needed to be made was to the stern ladder clips, which were too short to hold the ladder securely to the rail while under way; Railmakers extended the latches for us about one inch and this solved the problem. By the way, if anyone wants a set of Stern Perch rail seats (designed for the early model stern rails), they are available at a very reasonable price (e-mail me at goodrich@moonspun.com if you are interested).
Next on the agenda:
Have we forgotten anything? Probably. But we plan to live aboard for a while before leaving the coastline too far behind. We'll update you on our progress in the next issue of Mainsheet

Miscellaneous Tips
1. SPACE SAVER:A convenient place to stow linens, towels, and bedding is to buy
large pillow shams and instead of filling them with pillows,
fill them with your linens, etc., and then use them to decorate your sleeping quarters.
(contributed by Cindi Goodrich (Moonspun))
2. CABIN NOISE: Under power, the Catalina 42 generates between 90 and 95 decibels of noise in the interior of the boat. By comparison, your average automobile generates about 75 decibels at freeway speeds. The noise on your Catalina 42 can be significantly reduced if the hollow companionway steps are filled with dense, closed-cell foam, and then covered with a sheet of 3/8" foam before reinstalling the silver heat shield. This treatment drops the interior noise level from around 92db to about 80db. (contributed by Jim Goodrich (Moonspun))
3. NEED MORE STORAGE SPACE?: The Catalina 42 was developed
as a great coastal cruiser. As such, storage space was traded for living area. However, a
few nooks and crannies area available to store your gear/food/what ever. On great place is
the space behind the mirror in the forward shower. Removing the mirror reveals a void
beneath the anchor locker (this is the access to the anchor windless). You can build some shelves in here (make them removable in case you
want to get to the windless). Complete the job by attaching a stainless steel piano hinge
to the mirror and bulkhead so that the mirror swings open like a cupboard door; also add a
strip of self-adhesive foam to the mirror frame so that it closes quietly; a latch
finishes the job. (contributed by Jim Goodrich (Moonspun))
