Harrigami is a folding, trailerable proa based on what I learnt with Harry, my 12m/40' proa (Harry + folding/origami = Harrigami).

  

 

'Hurry Up' our Racing Harrigami is in one piece. The demountable kiri/carbon beams are installed in sockets in each hull. Not super rigid, but at 6.5m wide it wasn't expected to be. Windward hull (strip planked kiri/glass) weighs about 50 kgs/120 lbs. It won't be much fun to live in, but could not be any smaller and meet the rules.

Harrigami is 10.5m/35' long, 5.25/17'6" wide and has all the accommodation in the windward hull, the short, fat, high one in the photos. This hull has full headroom, a huge double bunk and a single, plus table and seats, the galley and toilet, all of which were to be installed before it was launched.

It is 8m long (Harry's was 7), wider and better set out. The materials weight of Harrigami ready to sail was 525/kgs 1150 lbs. The finished weight is 550 kgs, with bunk and galley installed, but table and seats yet to be finished, or started, for that matter!

For racing, the windward hull is easily detached and a much smaller, lower drag hull installed. The long skinny hull is always to leeward and has the rig and rudders in it. Harrigami will use the rudders and rig from harry. Perth is far windier than Brisbane, and the boat is lighter so the rig has been reduced in height and area.

Harrigami took 449 hours to this stage, including mistakes, testing, thinking time and cutting and shutting to lower the cockpit floor, excluding a few weeks of messing about with the trailer, the paint job (68 hours), altering the boom, mast and rudders from harry and playing with the folding system.

More about Harrigami's construction.

Freight to most major ports is about $aus4,000. Not bad for a 10.5m/35 footer with full accommodation.
