We live well inland and don't usually do a lot of work on large marine products; but like about everything else there are several ways to go; you can use what you want for the headliner in a boat. We've used automotive headliner in motor homes and airplanes. Some of these had something; sort of like wall paper in them originally; but the owners decided that cloth or vinyl auto headlining looked great, and it was easy to work with too. It's kind of like this, if it works and you like it, I suppose that would be what was the best thing to use, the customer is always right. If a person was looking for the original that was in it, the dealer would be where to go.
