A traditional pram design built for the rigors of program and club use. The SailCube is a singlehanded junior training boat with rigging similar to an optimist, but with the durability of rotomolded plastic. The majority of the parts found on the SailCube are interchangeable with standard optimist equipment. A favorite of camps and clubs, the SailCube is low maintenance and a cost effective solution for getting more kids on the water. 3-Ply Rotomolded Plastic Hull The 3 layer polyethylene plastic hull is strong and durable, while remaining lighter than other trainers. Compatible with Optimist Equipment SailCube rigging is designed to swap in and out of an Optimist, and vice versa. With nearly the same dimensions as an Optimist, existing storage solutions, covers, and dollies will work with the SailCube.
