Rob Denney has been designing some very interesting proa's over the years and a recent update on his website goes into more detail on his "Solitarry" model.
Solitarry
Solitarry is a response to the ever increasing complexity in yacht racing, which not only makes it ridiculously expensive, but far harder work than it needs to be. It reverses the normal spiral which leads to more weight and more sail area. By removing weight, the stresses go down, followed by the size of the components, followed by the sail area required which lowers the stress, and so forth. To make this a success requires some fairly imaginative innovations.
Specifications:
- LOA 15m/50'
- Beam 7m/24'
- Racing weight (preliminary) 700 kgs/1,540 lbs
- Sail area 50 sq m/540 sq'
- Draft 200mm/8” to 1.16m/3.8'
- Air draft 9m/30’ to 15m/50’
- Bruce number ready to race 2.0
- Bruce number no crew or safety gear 2.3
- Hull flying wind speed (theoretical, without allowing for mast flex)10 knots
