Our sailing experience on a 1987 Catalina 34 which we named 'Eximius' which google showed as the Latin translation for 'Special' We hope that our posts will help others looking to take their boat beyond the local waters as well as provide entertaining reading. I'm a Brit, so my view of entertaining may not match yours ;) See you on the water. The Journey Starts Here Paul

Back to the dock from the Haul out 2026
note.Engine Electrical Harness Revisited
The Engine Electrical Harness
I'm in the process of replacing the Engine Alternator External Regulator. The existing regulated is a dumb backup from the previous system, the new Regulator is a Balmar Max Charge MC-618-H
I'm playing with the idea of keeping the old regulator and all of it's wiring to serve as a backup if the New Regulator fails ( it won't be 'new' for long :) )
However, a supplemental reason: I'm planning on replacing our 'House' batteries. Currently we have 4 x Trojan T105 225ah 6v Batteries with a total usable 12v of 225Ah( 50% of 450Ah ). The replacement will be a 300Ah 12v LiFePo4 battery which has a usable capacity of 90% or 270Ah at 12v. (Note, the 225Ah of the current Flooded Lead Acid Batteries is actually much less because the voltage of the batteries drop significantly as the remaining capacity drops)
Therefore, the Regulator must have a choice of "Lithium" Charging Profile and that means that the backup regulator must also have a "Lithium" option.
With that clearly in mind, I need to address the issue of switching over from the Primary External Regulator to the Backup External Regulator ( using an internal regulator is not an option for the safe operation of LiFePo4 Batteries)
If the backup Regulator was the same as the Primary, the switch over process could be as simple as moving each of the terminal connections from the Primary to the Backup - the Backup being already programmed to the same settings.
There's more complex ways to manage the switch from Primary to Backup regulator, but it's just not worth the effort. I figure that switching over the regulators would take all of 3 or 4 minutes and having to make any moves inside of the engine bay would take a lot more time and involve a lot more steps.
Ok, decision made. I'll remove the old regulator.
All that leaves is the method of connecting in the New Regulator to the Alternator, here's another crest to overcome.
When I rebuilt the engine harness in 2016, was it really that long ago? Yep! Six years ago, there's been a lot of water under the keel since then. Well, in 2016, I built a really nice engine harness and nicely labeled the wires in the engine bay, including transparent heat shrink tubing. Guess what! The labels are unreadable today! Six years being close to the engine heat and dust have made it impossible to even guess what the labels read.
The original ( to us ) engine harness was wired to a 'chocolate block' type terminal block. The terminations were not done well, the wires were burnt, not the correct colors nor sizes. The new engine harness wires were contiguous from the Engine Control panel to as close to the engine that I could get them, in some cases they went directly to the Alternator.
Now I realize the benefit of a terminal block in the engine bay. The most likely area of wiring failure is very close to the engine, especially for the smaller gauge wires. So I'm going to install a terminal block.
Each wire will be correctly terminated with heat shrink tubing and I'll have a printed image of the terminal block so that wire recognition will be easy.
Then I'll run wires from the terminal block to there destination. That should result in a very clear, clean and with protection from the Vibrating Engine.
OK, decisions made. Now to draw up the wiring schematic.
Deck Leak by a Stanchion
We found a leak at the base of a deck Stanchion
The plan:
- Remove the stanchion
- Remove the screws and the backing plate
- Clean up the underside of the deck and determine the extend of the damage.
- Make a fiberglass backing plate larger than the stainless steel backing plate,
- Glue with resin to the underside of the deck and let it cure
- Redrill the holes
- Apply Butyl tape all around the top of the deck where the stanchion mounts
- Re-mount the stanchion with shorter bolts ( so that I can use a socket to tighten them ).
- Secure the SS backing plate in place and torque down the stanchion. All done.
- With the Fiberglass panel in place, next was Drill through from the topside
I marked the location of the new holes which would put the base plate of the stanchion about 1/8" from the corner of the toe rail and deck. I'm hoping that this will allow deck water to run behind the plate rather than build up until it's the height / depth of the plate.

Replacing Catalina 34 Diesel Fuel Tank. part 3
We have our new Tank
I stopped at ACE Hardware and purchased the fittings to connect the new tank to the originals. Basically two 3/8" to 1/4" brass connectors. Took about 10 minutes to find them but all's good, they are ready to install.
About Carr Enterprises
They have several machines about this size that can do all sorts of metalwork, mostly on aluminum but also Stainless Steel, our tank was a small job for them. Their welding area can handle it all.
The tank is made from 1/8" ( 0.125" ) aluminum.
One difference that I'm going to implement on the new tank is the provision of a Terminal block for the fuel sender wiring. At present, I have to cut the wiring in order to remove the tank. Again, I hope never to have to remove the tank again, but if I do, then I would rather not cut the wires. So a simple terminal block with ring terminals on each of the two wires will avoid that.
The new hose for the fuel tank to the fuel filter / water separator has not arrived yet. But I was able to complete the wiring for the fuel sender / gauge connection. The Terminal block is mounted to the top of the tank with some 3M VHB double sided tape. Worked great and there is sufficient room above the terminal block to be able to use a stubby screw driver to reach the terminal block connecting screws.
First Fill
Fixing our Propane Hose!
Replacing our Propane Tank Hose.
The broken hose is really just an indicator of the health of our Propane System, so we decided to fix it.- Remove the 9lb Propane tanks ( one was empty curtesy of the broken hose fitting )
- Cut the wires to the Solenoid inside the 3rd tube.
- Unscrew the 4 nuts on the lower mountings where they attach to the lower rail of the sternrail .
- Unscrew the 4 nuts that secure the stainless steel U bolts to the top rail and lift way the entire assembly.
- Remove the broken Radar Reflector ( on the mast )
- Replace the Standing Rigging.
- Refit the Propane system ( with new hoses )
- New Dodger/Bimini and Bridge piece
Quick update
Took the new hose to the boat this morning, totally screwed that up, neither end fits but not worth the cost of the return. I'll give it to the club's flea market in January.

Replacing the Standing Rigging on our Catalina 34 Sailboat
Replacing the Standing Rigging. ( Part 1 )
I took photos of each bag before unwrapping them in order to check that each had the correct kit of pieces - Turnbuckles, T-Bolts, Compression Fittings, etc.
- Secure the mast with an extra line from the mast head to the deck
- Ease the Turnbuckle at the foot of the shroud/stay
- Climb the mast and release the shroud then lower it to the deck, descend back to the deck
- Disconnect the lower end of the shroud to the chainplate.
- Lay the shroud/stay on the dock and mark the new one to the correct length
- Cut the new shroud/stay and make up the compression fitting
- Ascend the mast and hoist the new shroud/stay and replace it
- Back on deck tighten the shroud.
