The trailer was designed for a rib and is extendable from 14 - 21'. I got it at a very knock down price, which was all I could afford at the time.
The problem with the trailer is its design. The hard rigid plastic rollers play havoc with the lapstrake design of Arwen's hull and so the paint regularly gets slightly damaged and flakes off leaving grey patches on the bottom planks and hull base.
Thank heavens, there were three top coats, three undercoats and three grey coats over the fibreglass!
Cut to the chase - I saw this picture of a trailer for a navigator, Now I am wondering whether I could remove the side rollers and replace them with bunk planks?
