15.25 m [50′] carbon sparred racing cat

“HI – OCTANE” is the contemporary “Blade Runner”. It is lighter, longer and has a higher Bruce Number [power to weight ratio] of 1.96 with its working sail. Most of this performance gain is attributable to the carbon fibre aerofoil section rotating mast and the carbon fibre cross beams. The connecting structure is stiffer [twice as stiff as the alloy of the BladeRunner] and stronger [three times as strong]. The carbon prod to carry all the big forward extras, with its wire bracing and tapered shape, is a work of art. However full of performance has not been gained at the expense of all creature comforts. There is standing headroom below and ahead and galley. There are even a couple of inboard engines to make sure that you can pick up that mooring and guarantee that you can get where you want to go regardless of the conditions. But of course, these can be omitted in the interests of lighter weight if you wish. Construction is in strip plank cedar composite or strip plank foam. The “split half” method using female frames is used with CNC cut MDF frames provided as DXF files from the surface model.

Booklets on a construction of such items as glass fibre underwater foils, composite beams and wing masts are provided with the plans. Booklets also cover the various components and construction techniques such as stressed ply, strip plank cedar composite and strip plank foam that are appropriate to the particular design you have chosen. They also deal with setting up mould frames, flat panel and ply/foam/ply construction and vacuum bagging and resin infusion if you plan on using those methods.
