Boat Rub Rails, Mouldings & Trim

Wondering, "How much rub rail do I need for my boat?"
Well. most folks use one of two ways to determine how much rub rail they need to purchase. One is to measure the amount already on the boat. The other is to measure the length & width of the boat, add those together & buy double that amount.

It is suggested to get an extra ten feet (10') to allow for some trial & error.
