The Sondes 230 is available as DIY plans, a kit and as the complete custom built boat. It is a little based on the Romney 2.2 but has a plank added. All the planks can be cut from a standard sheet of 2.44m x 1.22m plywood - no scarfing required. It was designed as the Winchelsea 2.2 with the long keel section replaced by a flat keel plank onto which a length of timber and a skeg are fitted. The open edge of the stem is capped with thin strips of wood that are carefully bent round to join at the keel. The flat keel plank makes for an easier build but it is still built in the same way - over a mould. However, it could be built using stitch & tape if you don’t mind the stitch holes. If you’re painting your hull inside and out, this is not a problem but, if you want to varnish your hull then I wouldn’t use it.

Basic Materials Required
Plywood – 2 sheets of 6mm exterior or marine grade for the hull, 1 sheet of 9mm or 12mm ply for the mould, transom and the seats, for the knees and breast hook. Solid timber lengths for the sheer trim 2.4m or longer. (The mould can be made from 12mm chipboard or MDF as a possibly cheaper option). 4.5kg Epoxy pack
