Twenty-six of these were built in epoxy composite iroko strip-plank in Spain by ‘Carera.’ Then most were transported back to the UK and became very successful racers.
See RUSTLER 31 which was a later version developed for fiberglass construction.
The Rustler 36 is also a descendent of the North Sea 24.
