Where would I find a one?Welcome aboard:
The rub rail is not OE, really. It was a supplier piece. You can buy any rub rail that fits your channel. If you need a new channel, you can find that as well.
Post #3Where would I find a one?
That is the problem...I took the boat to a marine repair shop...and the put a new rub rail on it a were just clueless...poorest workmanship I have ever seen...and then, took the old one and threw it out before I could get a piece to measure and photograph...it was a stainless rail with a white insert...and the back side of rail clamped the hull and deck together...about a half inch lip on both that the rail sandwiched...Just to add to the advice already given . . . If you have a section of damaged rubrail, you should be able to take a small piece of it to see what the cross-section looks like and approximate dimensions. Then match it up to the many rubrails on the Taco website.
If the manufacturer (Larson) has an active tech support / customer service group, they can often tell you what the rubrail is (brand & profile). Many boat manufacturers use Taco rubrails and related trim.
