It's some wierd Canadian off-white color. They do look greyish in that pic. I had trouble matching the color to do repairs and the guy that had it before me did a bottom job with a color that did'nt match so since that pic I re-gelcoated the hulls with a color that I can duplicate. They are still very similar to that color.

Around here and the way I use my boat white or an off-white is the only way to go. If I had something like an A-cat I would go with a cool paint job or darker colors.
