It's not necessary, but.......
If you leave the boat in the water 24/7 for many months, AND it is a Glass/Polyester resin boat, at some point, the likelihood of you getting blisters on the boat is high.
If you plan on parking your boat in the salt water for many months, a barrier coat is probably a good idea.
If you liked my advice/response, give me some rep points. If you didn't......well what do you expect, it was free.
