Catamaran’s hulls rest on two cross tubes covered with vinyl rubrails outside the wheels. Eyelet on sling handle prevents slippage on steep ramps. Dolly breakdown using the snap buttons on tongue tube. Pneumatic, non-corrosive, 16 x 4 wheels can be secured on wheel shaft with provided screws for added security. For soft sand conditions, tire pressure can be reduced to increase tire footprint. Proudly made in the USA.
