Hi, Sailing getting up in air easily, steering to controllift. Nose not digging too bad, but rudder develops those drag streams - separation off the foil at...

G'day, Excellent! Any idea how quick it goes with the hull up? How much wind to get it flying? Have you got a plan for it it goes over? The masts will ...
Doug, You've really done a great job with that boat. Most of the people on the various proa forums, including myself, are full of theories that they're more...
It was a little gusty - easterly, 10-15 knots? Speed 11-13 knots. Guessing, GPS not on. Shame about the rudders - they get that separation that you can see...
The March 2008 US issue of Sail magazine described Harryproa in the New Boats column on page 46. The Kaidoz 31 received more picture space and less text. The...
Mike, I first started with a little bit of sailing, then started building, now I'm a bit over building and sailing though I want to sail this one around the...
just checking into this group. Thanks for all this fantastic stuff. My interest concentrates on the Solitarry as a very fast boat with off shore capabilities....
G'day, G'day, Welcome to the group. The core is 12mm Divinycell, 80 kgs per cum m. The surface area of the ww hull, bunks and cockpit is near enough 32 sq m,...
Doug, I'm glad you're doing it. I always seem to be two to five years away from a proa, so it's great to see people working with the design in the meantime. ...
I was wondering if any have given any further thought to a timber spar. Don't freak, I know the carbon spar business is in need of support. and that the...
G;day, It will be heavier, possibly more expensive and will either bend more or be a bigger section than a carbon one, but none of these are deal breakers if ...
Bow burrying is one of my concerns with this design, any one considered if the addition of side lifting strakes would improve this characteristic? drag wise...
How aboue the bow design as on Cheers: http://membres.lycos.fr/ugmarie/zacheers/cheersjpg/rougevinbaville/cheersparrougevinbaville0005.html No extra drag in...
I can't see why bow burying should be a problem. The boat with a high prismatic coeffient and long bows has plenty of hydrostatic lift with a long lever arm...
Consider bamboo strips. Quality bamboo has better characteristics than most timbers. Check out the Youngs modulus and breaking strains of the bamboo used in...
... Interesting idea. I have worked with bamboo a little including fly rods and bows. The main advantage in fly rods is that it allows the creation of rods...
G'day, I agree with Robert about bows and anti dive plates. My Elementarry rudders don't ventilate at 18 knots, I suspect that Doug's problem is more shaping...
Robert , I totally agree. I think it is best however to steep the bamboo in some hydrogen peroxide to reduce the starchand proteins and then steep in a borax...
Fellas, Just bought the latest edition of the Oz mag "Australian Multihull world" (issue # 89, Mar/April 2008) and it has part 5 of the on going story of the...
G'day, Mark and Michele have left harryproa. A more or less amicable split, neither of us liked the way the others were doing things, so decided it was ...
Sorry to hear of the dissolution. That's never comfortable, Rob and I wish you the best in your pursuits in the future. Do you have a referral email for Mark? ...
I wish good luck to all... and I must admit some frustration for the lack of information on new progress. I still don't have either time and money to build my...
