A tighter focus on the boats with less "empty space" of the sandy beach surrounding them would have immediately called our attention to the colors within the boats. As the image stands now, the viewer notices the beach and two boats sitting there at first glance. Then after we look at it for short while we notice more of the details. A tighter composition that primarily just contains the two boats within the frame would capture our attention more readily.
I think this is mre red and blue than red and green or orange and blue. I like the overall look of your image. I think it would have more imapct if there was nothing but sand and the two boats.
