One interesting development in the world of Sailability is the seeming move away from fast boats to simple boats, driven by the need to try and get back into the Olympics by actually having world wide coverage. The Hansa 303, which is pretty much the Laser of the Sailability world is growing in leaps and bounds.
I spend the day coaching "buddies" for the boats. Getting the most out of the boats takes a few tricks and a surprising amount of finesse. |

What about the oft quoted end plate effect of having the base of the sail close to the deck. Roll back 30yrs and the boards were always going on about it as I'm sure iGRF and others will testify |

And leverage? And tilting the boom changes the effect of the kicker I'd guess.

Just to clarify it's the D0 we're talking about? I can't say the boom height was much of a problem as to end plate effect the boom doesn't go quite as far down as it can on a board or something like a Europe, or Contender, but the rig generally on the Zero is about the nicest set up I've ever seen on a dinghy the like of which we mess with. There's definitely something faster about lower aspect sails per given area on displacement speed boats, wether it's the end plate thing, wether it's just the extra length of the sail chord and being low down being brought to bear, I don't know, but certainly the efficiency of that zero rig over that 9mtrs of sailbag that propels the Aero you can feel if you switch between them.

To get a significant end plate effect you need the sail touching the deck all the way along, and probably most especially at the leading edge, which was what the boards did. For example there was a big gain in dinghies in the 60s when jibs moved down the forestay from 6 inches above the deck to touching. |

I think you'l find it discriminates against anyone outside of the normal. At the other of the spectrum it is just as bad! |

What do you think makes more, hull width or toe strap width?
The danger if you allow people to move their toe straps out, everyone will do just that and just have less leg supported by the hull. It might not be the best thing for everyone knees.

There's lots about that in the fascinating book "The Economics of QWERTY" that claims that BetaMax wasn't actually the superior format for most users. For example, VHS had bigger cassettes which meant longer recording time so US viewers could record an entire football game at a time when conemporary BetaMax machines couldn't, and for most users that was more important than machine size or superior vision. The relevance of the book is that it shows that many of the claims of path dependance in which we get locked into inferior standards are simply myths. IMHO that applies to the popular sailing classes, where some people deride the more popular boats or types of boats because of their supposed technical flaws and miss the fact that the most popular classes achieve that status because they simply work better for most people. As some have said, the whole "foiling is the future" rubbish seems to fall into that sort of category. Okay, foilers are the 'superior format' if you're interested in going really fast on a boat, but they aren't a superior format for most people to enjoy their sport.

Ahh, the Rs - poster child for the pitfalls of chasing development. Even before their home town suffered from an earthquake they were down to about 9 boats at their national titles and the number dropped when they started foiling. Considering there were once about 400 registered boats and they arguably led the entire dinghy design world at times, it's a very sad tale.

How tall are you? I'm 5'7" with a medium-length trunk and short legs and it doesn't seem worse than most other boats.
