I drew the Naskeag 16 design for the Wooden Boat organization, for publication in Wooden Boat magazine and for building by students at Wooden Boat School during their hands-on summer boatbuilding classes. They felt a need for a more modern family sailboat than those offered in most of their classes. My aim with this design was to produce a versatile boat that is capable of being diffferent boats for different people. It needed to satisfy the needs for a safe and relatively sedate family cruiser or day-sailer at one extreme and an exciting high-performance skiff-type trapeze boat with large asymetrical spinnaker at the other extreme. Between these two there is also a more middle-of-the-road sloop that is suitable for general club racing and other rigs may be drawn if there is sufficient demand for them. This can only be achieved with a hull that can move well with a smallish rig; a fast hull can sail sedately but it is difficult to make a high-drag hull sail much faster than theoretical hull speed. The Naskeag 16 has an easily-driven multi-chine planing hull that will produce a small wave system from which it will be easy to break out. It will be as comfortable surfing at high speed across the wind chop of a big bay under asymmetrical spinnaker as gunkholing in backwaters under the relaxing lug rig. The high-prismatic shape, with unbalanced plan shape created by a fine bow and broad stern, minimize pitching in lumpy water. That characteristic creates a boat that can keep sailing when many others are stopped by pitching, because the sails and foils can operate in more stable flow.
Construction uses a ladder-frame plywood framing system of interlocking backbone and frames. The backbone, along with the centreboard casing, acts as a lightweight girder to create a very stiff hull that will not distort under rig and wave loads. Hull, deck and cockpit skins, as well as the bulkheads, are 4mm okoume plywood. Backbone and centreboard casing are 6mm. The transom and its doubler frame are each two layers of 6mm. The cockpit configuration is planned around the nearly 8ft clear length of the cockpit sole and width to sleep two adults on camping metresses, one on each side of the centreboard casing. The self-draining cockpit eliminates the need to keep them above bilgewater by means of cockpit grates or floorboards. The foredeck is sunken below sidedeck level to form a sleeping area for two children or teens, to suit a small family. A boom tent will make for snug weekends afloat.
The cockpit is watertight, self-draining through the transom. Under the foredeck are large stowage compartments to stow camping equipment, accessed through two large watertight hatches. There are three stowage compartments under the side decks each side for smaller items, all waterproof and accessed via watertight access covers. I have located additional watertight access covers in bow and stern to allow for ventilating the hull internal spaces when the boat is being towed or in storage.
Foils are NACA sections, with full-size patterns included on the drawings. The centreboard is elliptical in plan form, with straight leading edge. This allows it to maintain an efficient foil section shape at whatever angle it is set, while using the centreboard angle to adjust helm loading, from fully down for winwdward sailing to mostly raised for downwind. The Naskeag 16 can be built from plans only (which include full size paper patterns), plans with optional Mylar patterns, or plans with a CNC plywood kit. Plans can be ordered from our pricelist. Kits will be available soon.
