It's amazing how much attitudes have changed. A couple of years ago, any mention of proas started a fight. This thread, 6,600 video downloads in 5 days and some offers of crowd source funding represent a big change of perception. I am grateful for all the encouragement.
Probably won't get to Wangi or Geelong this summer. Local (Gold Coast and Brisbane) races, maybe an offshore trip, then the Bris Gladstone. Hopefully by then it is debugged enough to charter it for the races north and Airlie, Hamilton Island and Magnetic Island race weeks.
Shunting is one of those things that seems tricky until you do it. The tacking rules apply. I will certainly not be pushing any limits at mark roundings with people who don't know how proas are sailed.
Shunting downwind is slower than gybing, but there is less chance of a stuff up, especially in big wind/seas.
An inshore charter version would be pretty similar. Most of the compromises are for charter operation rather than for offshore racing. I doubt that a proa will beat a 32' cat on foils, unless the proa was on foils as well. Stay tuned.
Stayed masts are problematic on proas, for many reasons. They are also complex. I would not be offering to pay for any non collision damage if the boat had a stayed rig.
A 6hp outboard is mounted on a lifting bracket on the beam.
15 or so years ago, the self appointed Pacific proa police made a big fuss about me calling it a weight to windward Pacific proa. So I called them harrys. Enables some amusing names (Harrigami, Visionarry, Solitarry, Dirty Harry, etc) but made it a bit harder to be taken seriously.
The rudder blades are modified ogive sections, symmetric fore and aft. They work in both directions with the curved surface on the windward side. They are in cases so they can be lifted for balance, shallow water or running up the beach.
If it is banned it will be due to ISAF Rule 1.01.1. Which states "These rules do not apply to proas". AOMRA, SSSS and sundry other clubs have so far been welcoming, but if there are any problems, I don't mind racing unofficially until the rules are changed.
It may or may not perform as well as the numbers suggest. It certainly won't beat the ORMA tri (OMR rating is ~1.245 vs 1.417). The high aspect ratio rig and the rudder section shapes are untried at this size, but work well on smaller versions. Either can be easily changed if required.
We will not be building any new boats until the first one has proven itself.
Anyone who can get to the Gold Coast is welcome to come for a sail.
