Key Layout & Premium Features

The SLDH Floorplan (Single Lounger with Dual Helm): * SL (Single Flip Lounger): Features Harris’s signature multi-position rear lounger at the stern. It effortlessly converts from a spacious forward-facing bench into an expansive, plush rear-facing sun pad for premium dockside or sandbar relaxation.
