Paint Question

I am refitting a 24' trailer sailor. Boat was solid white with off white nonskid. This is my first sailboat, so my first refit. I have repainted the deck white and have done the cockpit nonskid in battleship gray. Transom has been painted navy blue.

My question is how much difference in temperature does paint color make? I know white reflects and black absorbs. However, to the touch, there seems to be a considerable difference in temperature between white and gray and blue and white on the boat. Living in AZ, heat is an issue. Will the blue and gray turn the cabin into an oven more so than a lighter color? In regard to the deck, will the gray be a frying pan compared to an off white? Any help would be great.

Re: Paint Question

Definitely, the darker the color, the more frying-pan effect and the oven- like interior. In the interior, insulation will tend to help, but why fight the laws of physics? Use light paint color, good sunglasses and skin protection, maybe sunshade over the cockpit.

Re: Paint Question

Even light grey is hot. As in too hot to walk on in barefeet with the sun overhead. Best colours that aren't white are beige/cream and maybe a light blue as well.

Re: Paint Question

The non-skid on our Wildcat is light grey. Currently in Florida and we can't walk on the deck barefoot after 10am.
It also raises the interior temperature.
We are repainting all the non-skid in white this month.

Re: Paint Question

It is just amazing how a light gray can be hotter than a white or light cream. A wavelength expert could probably explain it, I guess.

I had some left over paint, light grey, and decided to put another coat on my cockpit sole over the winter.

Now, it's too hot at times and you have to put on flip flops or something. I may have to repaint white soon.......

Re: Paint Question

Thank you all for the quick and helpful responses. You have confirm my fears. I was hoping that the color would not make that big of difference. I guess its back to the paint store (online of course in AZ) and sanding. White and off-white it is.

You wimps just need to toughen up those feet! (Just kidding!). My father knew a guy who burned his feet on hot pavement in southern California, got gangrene and lost both feet.

Re: Paint Question

Not too bright a white. It'll be cool to walk on but will blind you in bright sunshine.
