Custom DEEP Oceanboards 18 foot x 23 inch unlimited board. Dugout design. Steering is setup for goofy but also have the steering arm for natural and is easily swapped over.
Amazing board for downwinding. Picks up the slightest bumps with ease. Don't let the width scare you. Only 23 inches but amazingly stable and this translates to fast. Water deflector fitted to reduce water into the cockpit.
Located in Melbourne but willing to ship interstate if the buyer organises all frieght details and cost. Someone like the kayak courier would be a good option.
