I've installed BarBour Plastic rub rail on a charter
cat. That started life with no rub rails. I want to say they were 2 7/8 half ovals. Worked great.
R1016 part number.
We drilled counter sunk holes in the hard plastic rails every 6 inches, held them up to the boat and spot drilled the boat, then came back and over bored the boat with thickened epoxy
, re-drilled and tapped the holes. Buttered up the machine screws with thickened epoxy
as they went back in, and used an impact driver with the clutch
set to do the job.
No nuts on the inside, no leaks
on the inside... Did it from a floating dock. 36 foot cat in 3 days. To do it that way you need something to drill into, the boat was wooden and had a sheer clamp thick enough to take the bolts. I liked working with the stuff, as it is mostly self fairing. With a heat gun and a piece of plywood
as a layout jig you can shape it to follow down the stern steps too.
