This spring, I did a bottom job on my boat and just sprayed gelcoat to the repair area. I have beige hulls, so was not able to get a perfect colour match. Since sailing season creeped up on me, I decided to wait until this coming winter to spray the entire hulls one single colour. I was tempted to go white, because that's the colour it usually comes in, but then saw a video on Youtube of a cat with black hulls, and I'm considering that colour.
My boat sits outside from June to September and in the sun half the day. Since black attracts heat more than white, can that have a negative effect?
Note that the average daily high is in the mid 20s Celsius and we maybe get a week or two of mid 30s celcius. I think that works out to 80s and 90s in Fahrenheit.
