I see a lot of black kayaks and wonder the logic. I owned a black Nordkapp and had to be careful touching it on a hot sunny day, not something you wanted any tender skin to contact. It was prone to raising the hatches to the point of bursting but the worst thing it did was structural. On a warm day but not really hot, I noticed the hatches sucked in rather than out, odd. Then I noticed the bulkhead lines on the outside of the kayak her pronounced and I had not seen them before. It was as if the outer shell increased in size and left an indentation at the front and rear bulkhead all the way around the hull, very disturbing.

This was the one time I left the hatches on but could see it as a major problem over time. Pinholes in the bulkheads could have prevented but a lighter color would have eliminated the possibility..
