see i started that ( with only a link ) but it is thanks to Jeff's work how it looks now
perhaps good to add kites, solid wings, tips, slot effects, arelons...

I thought the Wiki was very well done. I clicked on the discussion tab to see if there was any ... and it looks like I started a thread.

It is too bad that the age of commercial sail was over before the advent of stainless steel rigging, Dacron, and GRP hulls. I wonder how working Sail Plans would have evolved using modern materials and not effected by racing rating rules?

ah, so thats how it works and i share the wondering

like to mention the good sail airodynamics thread here
sail aerodynamics
and find lots of controverse on the slot effect in sails
http://www.onemetre.net/Design/Slot/slot.htm
http://www.arvelgentry.com/magaz/Ano...lot_Effect.pdf
http://www.arvelgentry.com/A_Truer_Tale.htm
yet also that even old dutch windmills seem to have used the effect
biplanes should get better constant lift from it and discovery's
"wind driven" tells square rigging slots works just as well vertical
dont know but to mention plain, split, slotted or fowler flaps

edit: ah, so thats how it works II
another arvel gentry document on foils including bathtub flow expiriments

a wise man once told me the more you learn the better you realise how little you know
so here i am with a pile of books from the technical library

Yeah not bad, but considering that this is supposed to be some of the more knowledgable people in the game not good either. for example no mention of moonrakers or stargrazers, OK we could go on for ages I know but is this going to be the definate article or just somebodies mindless ramblings? (standing by for incoming on that!!)

[safewalrus]

Rhough - I'd argue against stainless rigging and GRP hulls in a commercial environment - weak flimsy and expensive, prone to failure at the wrong times too!! Like epoxy paint - lovely stuff but needs ideal conditions to apply - how often (in the commercial environment) can you hang around for days not making any money waiting for the ideal conditions to apply a lick of paint? Never!! so it's no bloody use is it? This is from sound commercial experience I can assure you!

I've started breaking the "sail plan" article off into more detailed articles for the more common of the sail plans mentioned. Will look into getting some templates set up to make it easier to add stuff.

Don't forget to browse the wiki http://www.boatdesign.net/wiki/Special:Allpages and start adding your knowledge....

good work Matt, searching for my reps i came into this desolated wiki again
and if you dont mind like to add the not so common crab claw / delta wing

no, its not the aspect ratio but vortex lift that keeps loading at higher speeds
AR however... well, a pointed mast/sail does have a longer leading edge rite and
maybe it can have a faforable leading edge rotation, any reasearch known?
