Check out this new "Expedition Windsurfer" and SUP made from what appears to be a highly modified set of Chesapeake 16 Plans. It is very unique in that it combines sea kayak bow design and in-hull storage capacity with the ability to use as a windsurfer and SUP for both short and long distance - multi-day cruising. The next new CLC kit perhaps?
