Frank,
This is a very well composed picture and exudes calm and peace. And very well crafted. I like it a lot.
Two things seem just a tiny bit off. One is the color of the waves; at first glance, the light brown comes across like sand and makes it look like the sailboat is grounded. Then I see the whitecaps and structure of the waves and it is ok.
Second is the side of the hull. I think of wooden boats as being made of horizontally oriented boards. But you have the grain of the wood running vertically.
Just being picky. As I said, I really like the overall effect.
