Eximius - from the beginning
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

Solar Panel Failure
Solar Panel Failure
One panel failed - what it means and how we dealt with it.
Background:
We upgraded our our 3 BougeRV solar panels after our Standing Rigging update resulted in a change of the Backstay which, in turn, meant our old panels would no long fit in the area available. I chose Renogy Solar for the new panels. Purchased them from Amazon and built a new Solar Panel Frame to support them.
That was in March this year, so they are only 4 months old - and one failed!
Do Solar Panels failure due to 'Hot Spot' happen? Apparently they do in about 0.04% of installations, we just happen to have one that failed.
IMPORTANT: The first thing I did when I realized the Panel was broken, was to disconnect that panel from the system intent on eliminating any risk of further damage. Only the panel has failed, there were no signs of any other damage. Once the broken panel was disconnected, our solar production rose to over 200W ( our AC was running ). So the rest of the system appears to be just fine.
So now, the issue is how do we fix it and do we make any changes?
First the Fix
Will we make any changes?
However, locating a 2nd MPPT controller might be more of a challenge.

Locating a Coolant Leak on Universal M25-XP Diesel Engine
A Drip is still a Leak!
This is the fitting that is from the Coolant pump, the hose to the Hot Water Tank is attached to it.
Just in case you didn't know. Eximius is docked in Fort Lauderdale, that's South Florida - Freaking HOT!

Securing the Radar Mounting
Radar Mounting post was attached to the Backstay Bridle
When we purchased Eximius in 2015, the Radar Mounting post was braced by an aluminum tube that was attached to the Backstay just above the Bridle. So many things wrong with that even though many sailboats have the Radar mounted on or by the Backstay.
When adding our new solar panels after the Backstay was modified when we replaced the Standing Rigging in March this year, the Bridle is now about 8' above the solar panels but I still did not want to attach the Radar mount to the backstay.
This is the setup for the new panels supported on a 4040 Aluminum Extrusion frame, looks very neat and clean.
The Radar Pole was supported also with a strut that passed through the port side of the Bimini frame which prevented a Cockpit full enclosure. I removed that strut during the installation of the new solar panels.
There's one more supporting strut, it's an Aluminum tube attached near the top of the Radar Pole and lower down to the top of the aft railing near the Outboard Motor & Mount.
Plan its to replace that Aluminum tube with a Stainless steel tube.
Here's the schematic of the brace that will attach the Radar Pole to the Solar Mounting frame. Basically a piece of 4040 Extrusion, secured to the Port side Solar Mounting Beam at one end and attached to the Radar Mounting post on the other with a Stainless Steel Pipe Clamp.
Just need to measure the distance from the Solar Mounting Beam to the Pole, cut the piece of 4040 and shape the end to the curve of the Radar Post, then straighten out the Pipe Clamp and secure it in place using a couple of M6 bolts and T-Nuts.
Easy ( hope that doesn't come back and bite me. )
Ok, it really was that easy! After shaping the curved end of the 4040 extrusion using a grinding wheel on my cordless 4.5" angle grinder, down at the boat it took all of 10 minutes to install the bracing beam.
All done!
The strap is really secure. Sorry about the surface corrosion on the Radar Mounting Pole, it's not a 316 SS pole!Saturday, May 16, 2026
Replacing the Engine's Heat Exchanger
Typical Boat Project Creep - Leaking Heat Exchanger
During a routine engine inspection, we noticed a bit of coolant leak and I suspected it was coming from the Coolant Reservoir overflow due to an aged Pressure cap. After cleaning up the closed bilge under the engine and placing a puppy pad to detect any coolant leak with the engine off for a week or two, I felt confident that it was a leaky pressure cap. WRONG !! When I checked today the puppy pad was soaked with engine coolant. Clean Coolant! It has to be leaking from a hose, hose connection or the Heat Exchanger. There's no visible source of the leak and it's pretty minimal but a leak is a leak! Plus side? We now have a new Radiator Pressure Cap.
Can you feel the Creeping Project Syndrome kicking in yet?

This is how the engine looked in 2020, several things have changed, New design alternator support arm, New drive belt and pulleys, some of the hoses have been replaced with Blue Silicone.After:

New Bimini for our Catalina 34
Replacing the Bimini 2026
- Apply reinforcement patches where the Solar mounts attach. (DONE)
- Extend the port forward snap flap ( it's 2" too short ) (DONE)
- Expand the backstay holes slightly ( the canvas is stretched where the backstay bridle passes through the canvas and leather reinforcements. (DONE)
- Fix missed stitches on Binding port aft snap flap. (DONE)
