Matt, I'm convinced the whole black is hot thing is overdone. Sure if touched on the outside the surface will feel hotter than a white surface, but the amount extra of that heat that gets to the inside, especially with insulation, is quite small, as much of it is reflected heat from a shiny surface. Otherwise there'd be no black cars. And there is no doubt, black looks fantastic. The only mild negative is it might fade a bit faster and show scratches a bit more over time than lighter colours - so what?
An acquaintance of mine with a Clipper 30, did a full reno on her, and had her repainted a nice professional two pack black, about the same time, and same paint shop I had my Clipper 34 done in white. Mine looks really nice - his looked bloody terrific. So you just keep doin' what you're doin'.
Matter of fact, she's for sale even as we speak...well, type anyway. Erik spent a squillion on that boat. Sadly he won't get it back, but he had fun doing it. She still looks great, as that paint job, as shown in the link, is now 5 years old in that photo.

Nice black boat! I'm sure SOLSTICE will present herself as outstanding in black!
For the boat on the link in post above: 6 ltrs at 6 knts = 3.77 nm per U.S. gallon at cruise - economical for sure!
