K. So I'm confused. The hull you are showing is a Hydrodyne 20 circa post-1984 judging by the instrument pod being molded into the top deck and the cleats being recessed. Not an 18 IMO. You will need to provide more details to the community to get a response. Also, it helps to orient the pic correctly so we don't have to strain our necks, and provide many more of them with specific questions. Kevin-
