On what experience do you base those ludicrous claims? I have personally interviewed Russell Bowler, co-designer of the 40.7, and the designer of...
The idea won't work because it's based on false claims that masts create unfavourable drag. A search on this forum will show that is an old idea...
Wrong again - X Yachts did NOT "keep" the lines of the 40.7 at all. No person with any decent knowledge of yacht design would fail to see very...
You're dead right, sometimes things are not obvious. But there's arguably a tendency for people pr0moting "alternative" rigs to make overly...
If that's aimed at me, Montrero, I'll say I'm not particularly sceptical - I just dislike the way some of their fans use dubious methods and...
Some designers allow the Offshore Racing Congress access to ORC offset files. There are many fully measured 40.7s and therefore the ORC definitely...
You are completely misreading him. JE referred to the fact that there is no proof that windmill craft can scale "to any size", and the problems...
Think, is the fact that you happen to have the same fairly rare craft as one of the people you are quoting a coincidence? It seems unlikely that...
We are aware of the concept of upwind VMG and pointing angles.
As you note, those aren't particularly good boatspeed figures from that test.
Sorry, Unique, that remark was aimed at Herreshock, who is making some far-fetched claims such as implying that using a monohull as the main hull...
You appear to have the completely incorrect belief that there is only one "dominant trend". The wide, high wetted surface shapes are not really a...
The videos don't seem to show a real boat actually going straight upwind. Worsley's wingsail can do about 2.5 knots downwind in a strong breeze,...
Have you ever sailed a trimaran? Have you ever sailed a boat?
That's a speed of about five knots. What offshore sailing have you done? Why do you maintain this lie about a very slow 22 footer going 20...
The paper also projected a payback period of 8.8-14 years - but the lower end only comes into play if the ship does fewer voyages and therefore...
Not a rig I have any experience with ( :-) ) but when dealing with unknowns like this, one approach is; 1 - take some bottom-up photos of the...
I suspect you're assuming wrongly. I haven't done the calcs but I know that good dinghy centreboard cases are intended to be highly loaded for...
That post contains something that appears to be only an assumption. The centrcase in the OP's boat has a 1/4" ply web at the aft end and is...
Absolutely wrong. The corporate maritime world is NOT lawless and that is simply a fantasy of yours. Corporations build and operate craft that are...
