I haven’t been getting out much since I got home from Acadia. Last night I headed to the ocean. Seaside is the closest beach. A “bald” sky is not a photographer’s friend, but I shot a few anyway. I also managed to get completely soaked from a wave (not the first time).

I really like the cloudless sky in your images. The negative space works. If it were me, I would remove the airplane trail above the mast on the sailboat.
