Wild Hare phase 1 is complete

The first phase of the WILD HARE design is nearing completion. For me a design starts as a concept and that concept is developed in a series of drawings done on paper. It is a method I have used for 40 years and it is efficient and comfortable for me. Today I will complete the concept drawings with a drawing of the second rig design. The main hull, single aka and amas are drawn and I am very happy with them. The WILD HARE is a performance oriented version of the POCO design I did in 2001 for Windrider that became the WR10 trimaran. The POCO was a breakthrough design in that it used only one aka and short amas to simplify and minimize the construction and user assembly of the boat. The amas were developed to provide both stability and lateral resistance for the POCO and the boat sailed very effectively on all points of sail without the use of a dagger or centerboard, leeboard or keel. This made the POCO very simple to deploy to the water and to sail. There were only two controls on the POCO, the main sheet to trim the single sail and the rudder uphaul to lift the rudder blade when returning to the beach. This minimalist configuration proved to be so successful that I decided to proceed with further development in the form of the WILD HARE.

The WILD HARE concept is one and a half times as long and wide as the POCO concept but with a more favorable length to beam ratio for all three hulls that will allow it to escape much of the wave making drag of beamier hulls. It still maintains the single aka configuration but with a folding mechanism rather than with demountable akas and amas. For robust simplicity and ease of use the WILD HARE continues with a single sail set on a cantilevered free standing spar. The WILD HARE uses an ama shape similar to the POCO but with further hydrodynamic developments to increase lift. The WILD HARE concept design is intended for plywood/epoxy construction to facilitate easy prototyping but also to prepare it for a potential market as a kit boat.

There are two rigs drawn at this time. Both rigs are drawn to be 8.3m2 The first rig is a higher aspect modern full batten sail set on a carbon fiber mast. For prototyping it will likely have some variation of a half-wishbone boom. I hope to test some aerodynamic enhancements for the sail and a very interesting automatic canting system for the mast. Very, very, exciting concepts for an inventor and sail/rig specialist like myself. As I am expecting to make this design commercially available I will for now keep the details of the rig innovations under wraps.

The second rig is conceived for the home builder. It is drawn as an advanced version of a traditional rig so that the home builder can fabricate the spars without need for exotic, expensive materials. This version will attempt to reduce the drag normally produced by some similar traditional rigs. It is a lower aspect rig than the first rig and as one would expect, it is anticipated that this rig would not be quite as effective as the high aspect rig to windward. It is certainly possible though that the enhanced traditional rig would offer more power for off wind sailing.

Thanks to all of those who have sent questions and comments by email. As a general comment here in response, yes I am open to accepting additional inquiries in from potential kit manufacturers. Once the boat is ready I will be quite anxious to have the WILD HARE offered as a specialized kit with the option of a complete high aspect rig available with the kit or just the sail for the home built rig option.
