The shapely and seaworthy hulls of the Shetland Yoles inspired Iain Oughtred to design "Tirrik", but for modern materials and construction methods. Iain's design called for a wide bottom plank of 3/8" marine plywood and 3 topside strakes of 1/4" marine plywood. Instead I made the bottom planks of 3/8" white cedar with 2 layers of 6 oz fiberglass cloth in epoxy, vacuum-pressed to each side. The top strakes are 1/4" white cedar with 2 layers of 4 oz fiberglass in epoxy, vacuum-pressed to each side. This results in light planks that are extremely tough and stronger than the equivalent thickness of marine plywood.
The decks are attached below the top strake and are 1/4" cedar coated top and bottom with 6 oz fiberglass cloth in epoxy. Bulkheads, hatches and centerboard case are 1/4" marine plywood. Side benches and floorboards are cedar. Ash was used for the gunnels, floors and tiller. The central thwart, breasthooks, knees, keel and stems are cherry and the centerboard and kick up rudder are laminated from alternating grain pieces of cherry and streamlined. A smooth coating of graphite in epoxy was applied to the bottom boards, centerboard and rudder.
All spars are hollow spruce, with jaws, cleats, eyes, fairleads and other small fittings shaped from apple. Sails were made by Michelle Stevens Sailloft in Lunenburg, Nova Scotia, Canada. Two pairs of 10' cedar oars are supplied (one regular and one spoon bladed), made to Capt. Pete Culler's specifications.
