Doubtful.

No, on a 14.5 ton boat with 3 tons of lead outside, maybe another half ton inside.

What boat is this? It certainly isn't "Wild Eyes". When Abby bought her she had tankage for 25 gallons of fuel and she hasn't mentioned adding additional tankage. I hope she's carrying some extra though--with a diesel heater and 25 gallons she's likely to run out of diesel before she runs out of cold. And Wild Eyes is not a 14.5 ton boat with 3 tons of lead outside. Neither is Jessica Watson's "Ella's Pink Lady" nor Laura Dekker's "Guppy" so what _are_ you on about?

Lets see, 3.5/14 = 0.25 ballast ratio.
I'll pass.

Diesel has a density about 70% of water. Negative ballast. ;-)

Nope, not negative ballast. If it is inside the hull, it is applying downward force.

It's less weight than the displaced water. It has a net buoyancy. It will change the COG, though.

You are confused. The water displaced by the weight of the fuel is equal to the weight of the fuel. When the fuel is inside the hull, it has no "net buoyancy". Your body is buoyant when floating in the water. Now take that body of yours and place it in a 6 foot dinghy. The boat will be riding lower in the water. If your buddy gets in the boat with you, it rides even lower. Three guys, and the boat may swamp. Where is this "net buoyancy"?

You load up a boat with 40 tons of cork, and the net displacement of the boat is 30 tons....the thing will float away into the air!! Really!!

Depends on how many flies it attracts ...

We ALL know that 40 tons of feathers is lighter than 40 tons of cork. And, in the case of a 30 ton boat, it will leave a 10 ton hole in the water. It will. Really! . . . . . Now... horseshit is heavier, so Lew's argument doesn't hold water... certainly not 10 tons of it.

Hey, until this thread who'd thunk there was such a tight relationship between sailors and horseshit ... apparently damn near inseparable. ;)

Just outside the harbor at Gustavia in Saint Barts I saw a 15m catamaran (demasted) and being decked over completely with solar panels. I've wondered ever since how well that worked out...
...and whether the mast was replaced once the electrical work had been completed. Interesting solar project.
Might also be able to do something interesting with fuel cells. :)

------------------------------------------------- A Cat makes a great platform for solar panels, and yes I'm quite certain they restepped that stick when they were ready.
Biggest problem is trying to keep them oriented for max effiency which isn't easy on a moving platform such as a sailboat.

When designing a system you seriously derate the panels to CYA.
50% will get you in the ball park.

What would salt spray and evaporation do to the panels?

Salt spray will make them salt encrusted. You need to rinse them off regularly. Even a rinse with salt water (if that's all you have available) will help.
