As a sailboarder & sailor Ive been impressed with the speeds the hydro planing moths do.With dinghies you sit on the windward side.How come you sit to leeward on moths?
Shameless plug.
.I'm an artist.To see my latest sailing portrait go to my profile..
Dur.. I saw some footage on the Tv and you don't sit to leeward..What I meant was why is it that a lot of the time the craft is tilted to windard..the person sailing it is sitting on the windward side but that side is lower to the water..?
i think it's just because everything goes light once you are on the foils... then heel to windward while you are up so when you go back down and it loads up you heel a bit to flat, that way it doesn't stick the leeward wing in the drink and it goes from there???
I'm not really sure, probably not a reason for it
Here's a really good moth video:

If your interested in Moth sailing I suggest a peek at this Boat design .net. thread.
WARNING; its 83 pages long and occasionally raucous.

The Worlds are on starting tomorrow I think up at Lake Macquarie. Some details on this blog.

Might be worth a look if your close by.
Im here at belmont watching the moths. Awsome ****! Going to get me some of this here foiling action.
Kiting is out, sailing back in!
Thanks.
The first time I saw them was when I was sailboarding off Coal point in marginal winds <10kts & I wasn't planing.One of those flew / hissed past ..WOW 
I wouldnt mind doing that! But then I think I read they are hard to sail..? Also I don't have the funds..I haven't had a chance to see the video yet but will.
Last time I was out sailboarding in 25kts Ne off Coal Pt there were some Moths out 
.. very impressive but so were the cartwheel stacks!

Hmm you reckon the costs are fairly relative? ~25K is pretty steep for an 11ft, 30kg boat, no matter how much carbon and technology is in it.
To me they do not look easy to sail, look at any other top level sailing fleet and how many capsizes are there? Not that many. Go watch a moth race and it's carnage
Impressive boats though for sure, how they are 28kg fully rigged is anyones guess, that is insane. I sailed a moth a few times pre foil era and it was great fun, I reckon with the foils it would be alltime, if only I had a spare 25k lying around
My comments were based on an article by the woman editor of a British sailing magazine. She had the use of a new one for the weekend and commented how surprisingly easy it was to sail after only a few minutes coaching.
There was one on eBay a couple of weeks ago, not sure what it sold for. After the nationals and worlds there will be a few available. Foil kits are available and you can build your own hull. Carbon fibre is easy to work with. Roughly 10 times the cost of fibreglass cloth and you use the same epoxy resin. Hull is really small so materials are not much. Carbon tubes for the outriggers are off the shelf items.
When I was into moths they were built in 1/8 ply and it was not uncommon for blokes to build a hull to last only one regatta. If I remember correctly the hulls had a lower limit of 45 pounds then. This did not count the rig which was heavier than modern moths. Probably 3 times the hull material in the older stuff too.
Take another look, they do not sit to leeward on moths. They sit to windward like on every other sailboat.
