I0 11-12
IO 11-12: along the lines of Iota, but much beamier and more burdensome, and with a raked transom, too, all to give considerably more room. For 7 plank multi-chine or glued clinker. Stable yet fast, attractive and able, light yet strong, the seven plank aside hull goes together reasonably quickly to give a satisfying traditional appearance with modern materials. Two separate sealed tanks run under the side seats for a good part of the hull to provide buoyancy and strength

Closer in overall length to a 12 footer rather than an 11, IO nevertheless has a waterline length typical of many traditional 11 footers and it is on that basis that she merits the eleven in her name. On the left is the multi-chine hull with a modest 60 odd sq foot sail, and on the right the glued clinker version with 70 odd sq ft. As a long centreboard case rather than a daggerboard case has been chosen, either hull is to be built upside down over a few well spaced frames and an internal hog or inner keel for stiffness during construction. The multichine hull, taped or glass-sheathed externally, has been lined off to give the appearance of close-seamed carvel while the glued clinker with both gunwale and lower rubbing strips and broader planking has a more rugged, working boat style appearance.
The multi-chine version takes just 5 sheets of ply for the hull, transom, centreboard case and buoyancy tanks, while the glued clinker requires one additional sheet. There is no guess work or trial and error in the lining out of the planks for the clinker version as the position of the plank edges is clearly defined on the moulds.
Plans for both versions are on four A1 sheets with keyed construction and sail plan details, and on one A0 sheet with full size half sections for both hulls, including stem and expanded transom and bevels, with separate offset sheet table and, for the multi-chine version, strake offset table for drawing out the planks full size. The plans cost £57. Bubble wrapped packaging and postage cost £3 UK, £5 Airmail.
