I have a Bayliner 185 bow rider I bought new this year. When I lift the trap door in the floor between the seats there is about a 2 foot long crack in the hard grey material on the hull of the boat. There is no water coming through it that I can see. Is this just some kind of sealant put over the actual hull. Don't like seeing cracks on a 4 month old boat. It is near the center/bottom of the boat so I couldn't check the other side today due to rough water.
Thanks for any answers.
Possibly nothing. I believe the grey coating is thickened epoxy bilge paint. If they over-apply it, the coating can develop surface cracks where it the hull flexes slightly under it (the epoxy is pretty inflexible).
