Thank you, Will. I've decided to bite the bullet and add a metre to the mainmast, so the AR will now be 2.3. The real question is, taking...
I used Hayward's "Sun Cruise" UV-protected cruising sailcloth for my last two suits of sails. It's softer than other brands of regular sailcloth,...
Thank you, Tom. Yes, there is a constraint on the AR - I have to fit the sail to my existing mast. There is also a project to fit this rig, as...
And yet, I read things such as this, in Wikipedia, by Googling "elliptical wing": The elliptical wing was first used on aircraft in the 1920s,...
Nothing received, so I'll settle on a short yard, parallel to the battens.
Having settled on Eppler e422 as a suitable foil section that can be achieved in practice, the next thing to consider is the plan-form. The...
So how about starting another thread where you list those reasons, and justify your choice?
If we all sailed the same rigs on the same boats, it would get very boring, and we'd have nothing to talk about on this forum! If you use a...
This is the Omer wingsail, designed by Ilan Gonen, and there are working rigs on several boats. It's far too complex and high-tech for my taste,...
Thanks again. The conclusion that I'm reaching is that a cruising sailor such as myself won't be able to tell the difference between the...
In all the miles I sailed with this rig, I never encountered Beaufort F10. Enough F8 though, and some screaming white squalls around Tasmania....
Yes, simplicity is good. That's why I use an unstayed mast. If it's designed right, and built right, it's very difficult to make it fall down....
Photos taken when the alloy battens were made in NZ Here are just a few photos:
You've spurred me on to upload some footage taken in the middle of the Tasman Sea, just after a heavy squall had passed through. Naturally, the...
Everything you wanted to know about junk rig, but were afraid to ask. http://www.youtube.com/watch?v=6jM0LnEEXV8
Thank you. As I said above, I think I'm now in favour of e422 until something better comes along. Cl and Cd seem to be about the same as for the...
I can't really see this as a major advance. It seems to be nothing more than a double-thickness bermudan mainsail, with only moderate thickness,...
I'll have to remind you that i speak from the experience of 40,000 miles or so under this rig, the length and breadth of both the Atlantic and the...
Agreed. Yet there is a problem with this, in a soft wing. If the luff is broad and gently curved, it is rather difficult to keep it in shape. It...
Thank you. I've added Ncrit = 5, and lift and drag get a little worse above alpha = 12 with Re = 1,000,000, but not much. Airfoil Tools does not...
