The Sealion was originally modelled on our Seafox sea kayak but the use of Cedar Strip planking for her construction allows a more graceful and curvaceous shape both for the hull and the deck. She is built over computer faired mould shapes set up on a strongback (all details and full-sized mould shapes are given on the plans) in 6mm Cedar which is sanded smooth and then sheathed in glass cloth with epoxy resin.
