Devotti Single Hander

I'm not miserable..

I might be old(ish)

But I'm happy to enlighten young minds..

Especially when they're being bullsh*tted to..

Just think of me as a handy substitute for this...

Let me just explain why a flex top, or bendy mast isn't good.

It's for the same reason sailing upright is good rather than heeling.

Only worse in a way.

Heeling doesn't distort and destroy the foil, which disturbs the laminar
flow (look it up)

Unless the sail is cut so the leech tightens when the mast bends off to
leeward which clearly that sail isn't. (Old test of flextop windsurf rigs in
late eighties, pull downhaul, leech goes all floppy, lay on ground stand on
mast tip, leech tightens.

That mast is bending every which way. no way can it remain efficient.

Sorry if you think it is you're just plain deluded..

Edit come to think of it didn't I read somewhere they're already working
on another rig? I wonder why...

The point is when the wind gets up and down you windsurfers have to keep going out to buy more sails.

This is a one design boat, just like the Halo and others that try to take ALL things into consideration, not expect you to go out and buy new equipment to cope with the conditions.

get it??

Nahh probably not.

 

Originally posted by G.R.F. Originally posted by timg (sigh).... The reason why the mast bends like that is to cope with the huge mainsail. If you're gonna have a big main and the wind gets up you need it to spill off. You (GRF) will find this out when you sail your 100, if / when you get it. With the stays you will find more support, but then that's why you will have less mainsail area to worry about. The beauty of this main and mast is that you can use the power, right up to the moment that you need to start loosing it, as opposed to having a finite power that you could probably do with having more of, in certain conditions. So the next good thing about it....which to be fair, being a windsurfer you are going to have to start learning.... is the shape of the mainsail compared to the kite, it's very important to get the slot right (the gap between the mainsail and the kite). If you look carefully you will see that when the mast bends like that (cos it was made in bendy street arizona) you get the mainsail taking the same shape as the kite, hence creating the best lift out of both sails. And there you have it....simple. Looks different, but you know what??? It really works. Sighs? Ha I guess I should forgive you being just a dingy sailor stuck in the time warp. Here's the news from Planet Unstayed rig where we hold up 12 mtr sails with our bare hands.. The sail gets cut to deal with it RATHER THAN have a cheap bendy liquorice stick. So the mast bends off so you have to put up another sail then is that the logic? doh. Kind of plays to Mike Lyons HALO logic doesn't it, like what's the point?

Grumpfh I think your handicap here in understanding what is going on is because you come from a windsurfing background and have never had to consider segmented wing theory, as you have only ever had to deal with a single lifting surface at a time.  Both sails have an effect on eachother.  I am not going to recite chapter and verse on it here.  I will however suggest you read one of two books: Elements of Yacht Design by Norman L. Skene, and The Symmetry of Sailing by Ross Garrett, neither of which is a text book by any streach, and are simply interesting reads.  Both explain the basic theory in laymans terms.  I can lend you both of these, and hopefully you'll come back and understand what you are missing which has lead you to your mistake. 

Not sure how GRF still can't grasp the concept of a carbon mast that
bends off to deposed.

The actual odd Bit about this rig is the inversion, but if it works...it
works :-)
