This is a good point, and the problem is generally referred to as print through. BTW, if your boat is epoxy
-resin or has areas repaired using epoxy
, DO NOT paint
them a dark color. Most epoxy
resins start to lose a significant portion of their strength and soften if they heat up significantly, and being painted a dark color will often be enouhg to do that. Some aftermarket boat parts that are made of epoxy
resin have warnings on them to this effect.

The added heat (not inconsiderable) absorbed by the darker color that was formerly reflected by the white is what causes this to happen. If you have a temperature gun available - go through your boat yard and compare the temps of dark and white hulls. After doing that, imagine being inside of one of those dark hulled boats on a hot summer day.
Our resident expert painter here at Hartge's always warns customers against doing this. Some do it anyway and I've seen several boats that really look shabby because of it.
Stick with a lighter color - you'll be happy you did.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
