Oh, the masts don't need to be less than 25. They can overhang the towing vehicle with no trouble. As I said, I had a 25' trailerable tri and while I don't...
I have been thinking that the harryproa concept is just at the point where it could start expanding quickly, but what is holding it back is that people are...
G'day, I thought about the rudders on a sleeve, maybe later when everything else is working. They lose 2' which is a bit much for most marinas, I think. Foot...
G'day, ... Exactly what i have done. Takes a bit more mucking about attaching the large diameter bearing to the boat, but not too big a deal. regards, Rob...
G'day, Correct about the rudders. Not ideal, and could be corrected by mounting them on a sleeve on the beam, as per Robert's suggestion. trade off is...
... G'day, Could probably get close. We fitted harrigami in on a trailer, but there was no spare room. Hinged ends are pretty easy to engineer. As Robert...
G'day, There is one in Maine. It is the first one we built and was a costing disaster, resulting in me nearly going broke and the owner not talking to us. He...
-I didn't realise they took a full 2'. Still, 18' width on a 25' ww hull is still pretty good. Always add wings if you really want to push things and the...
If you search on "Rockport" in the harryproa group's web site, and then do another search on "Rockland", you'll see a number of posts written on the proa in...
Todd, Once again: no offense was intended. I guess I overdid the editing, which the moderators always seem to demand. I'm sorry if it offended you. That was...
G'day, I have though about this on and off for years. Always seemed too complicated. However, I've just been for a long walk along the beach (best non...
Yes, in my simpleminded way, I had the idea that you could just lay 3 4x8 foam sheets lengthwise and bend them up to form a 24' lw hull with 6" draft and 1.5'...
Oops, I actually have a spreadsheet that calculates this for me, so I should put the numbers from there (all assuming a prismatic coeff of 0.77): waterline ...
Sinse my reply is posted in along with your response. Is it faster speeds or better handling? Why any speed records haven't been broken by a two, three, or...
When you mentioned that the 40' Harry met most of my criteria, I went back and checked it. It is amazing that I had not noticed that my feature creep had come...
In the video http://youtube.com/watch?v=Mt-QZzlY0lM&feature=related The easy rig and claw on harry style model was same day testing. Test in roughly the same...
I really have no frame of reference when it comes to estimating how easy or difficult it would be to set up of tear down the proa. Rob, would taking the beams...
... If you regard the rear foil as the main leeway prevention, I do not see how it thus becomes unbalanced. The load on a centre board is large and if you lift...
It seems that the crab claw moves faster in video showing balestron and crab claw side by side. Not big difference but that's how it looks on the video. I...
G'day, Drawings and description of a harry for learner builders and sailors is in the files under harry for beginners. Gardner, I appreciate that this is not...
G'day, The beams run on rollers, but wedge into solid supports once they are in position. A sharp pull should get them started, then they are easily slid out....
G'day, ... Great minds think alike! ;-) ... If the 2 hulls side by side are withing the trailerable limit, then 2 hours should be possible. The mast is pretty...
The sleeved rudders are growing on me. Wait and see how Blind Dates work and I will see how they go on the trailer boat. May also see how strong the kid's...
