Gooday Doug - Where can I get some of those foils ??? That 'screw-on' or 'screw together' set of foils arrangement is just so good.I'll love to get my hands on a pair of those. Any ideas where they came from ??? Ciao, james

James, if you go to the "Foilers!" site( http://foils.wordpress.com/ ) and scroll way down you'll find the foilboard video. Just above it Fred has put a link to the original story of the windsurfer. Something like APS?
I don't know if you've followed development of windsurfer foilers or not but the originals used foils identical to the old "air chair" waterski foilers which were low aspect metal foils. They-generally-weren't as fast as "normal" windsurfers but the low aspect foils lent themselves to great jumps-and reliable re-entry. This all carbon foilset is higher aspect ratio and probably has much lower drag-and maybe poorer re-entry characteristics if they choose to jump.

In 25 knots I'm fairly sure that a Tasar would be roughly similar to a Hysterical 18 downwind, let alone a Hysterical 10. As far as I can judge, something like a Tasar, Fireball. Flying 15 or Vanguard 15 is about as fast overall around the track as a Historical 18.

I've never sailed a 10 but in my very limited experience the 18s plane a bit like an Etchells planes when it's windier; that sort of heavy planing feel. You'd probably be right, the 10s wouldn't really plane as we normally know it.

As far as sailing challenge, in my one (winning) race I got the feeling that in terms of sailing as we know it, the Historicals aren't massively difficult. It's more of a boat wrestle than the balancing act you get in newer boats, perhaps.

As far as racing goes, of course, the 10 with its tiny fleet wouldn't be close to the same level of challenge as a Tasar. As a guy who has placed in the top 4 in Laser worlds, J/24 worlds, Tasar worlds, Etchells worlds (I think) and second in the America's Cup said when he placed mid-fleet in our local Tasar champs, it's a very under-rated fleet.

The Skate

This boat has two sliding seats similar in type to the single moving plank on the International canoe.

it seems to be a silly design mistake, when the boat changes tack the crew will be sitting in the water causing a lot of drag. a quick p.m to me before construction and i could have advised them of this. oh well i guess i can not help every one.

There's plenty of people aged in their 50s sailing 12 Foot Skiffs. Twenty year olds are normally sailing slower boats.

David Raison on his very succesful scow Mini 650. The video is in French but you get the gist of it.

The Bermuda dinghy vid shows a main that has the boom above the foot, (sneaking up on the sprit boom concept). You can get some amount of leach tension without a vang with that layout. Not enough in this case. The boom is on the port side and the sail will lose a small bit of drive on that account. So the starboard tack is the less powerful of the two. Not at all what you'd want at the starting line unless you figure to port tack the fleet.

Help me understand this rig.

====================================
Seems to me that it might be a scheme to get the main as low as possible w/o smacking someone in the head. I can't really tell but it seemed like the boom might be curved so that it doesn't adversely affect sail shape as much as a straight boom?
Here is the vid again:

looks like a normal loose footed sail to me, I think the boom is straight, it is the fish-eye lens that makes it looked curved at some angles. I have made similar sails for my dingys, it allow boom to be higher and yes, get more sail area. And a slightly more favorable sail shape. easier to build as well.

Hey, they threw the spin pole overboard, I'm guessing they didn't need it again in that race and would retrieve it later
