 Topic: A question about Moff foils....Posted: 05 Nov 13 at 10:00pm |

Why do foiling Moths have "T" foils?
Aircraft that are designed to fly straight and level in flight use dihedral wings (angled up in a very shallow "V") to aid stability. Could this not be used on the Moth foils to make it "easier" to use, with the added benefit of the leeward "wing" giving more windward lift when the boat is heeled to windward when on the beat? To simple? Or is there something I'm missing? Additionally, do the rules preclude "winglets" to give the same lift for a smaller wing/foil, as on the C17 and others? |

The foiler has loads of roll stability anyway, so probably no need.

OK, I've never sailed one (bit on the chunky side!) so sadly wouldn't know.
Would winglets/end plates make the foiler "more accessible" to the heftier sailor though, for very little extra drag (I realise that a big guy isn't going to be properly competitive against racing-snakes in most conditions)? |

sorry to break it to you Boots, but you cannae change the laws of physics.
You (and I) are destined for a life of lowriding. |

I think its safe to assume that if there were advantages in endplating the foils they'd be doing it. Don't know whether its science or rules though.

Science, pays to go bigger on span. Winglets are good if you are span limited.

Was the not a story at this years worlds where people where experimenting with wing tips?
Presumable you have a limited span as you don't want the foil to break the surface as the boat is canted over to windward, therefore a shorter foil with winglets could potentially have some advantages

Unless you are 120kg plus then you have no excuse not to go foiling. Some of the top guys in the moth fleet are approaching 100kgs now. There is even footage from the worlds of one of them sailing with a bikini clad girl on the boat with them, on foils...
As an aside, I did notice that some of the foils at the moth worlds had little downwards pointing wing tips...

much as I wish your sentiment were true, when your local average conditions is around 8 knots, then sadly foiling is still much the preserve of the sub 90kg folks... unless you like a lot of time on a expensive mountain bike instead of sailing. I've noticed that our club boats foil before us windsurfers are planing.... they are definitely winning on the light wind threshold, although I think we can still take them when it's properly howling.... twice a year, on a Tuesday afternoon when everyone's working...
