I think that is a nice concept, but with a boat that small I would think You will need your buddy in-line or on the opposite side of you while running for proper weight distribution depending on the direction you are running into the swell. Because of that, it is highly likely your buddy may be...
all those decoration wraps look nice but the bottom line is that tuna cord or paracord get old real fast if you actually catch fish on them with any amount of drag.
My 2 cents:
Heavy drag/rail use: Shrink over cord
Under 40lb: shrink over cork tape.
Your hands and cap rail will thank you.
