Lighter weight crew than an RS400 I would have thought. Compare official RS figures. Given a more modern finer bow hull shape and a modern rig with better gust response/depowering I'd expect it to be mid way between the 400 and the 200 and probably faster than both. RS400 Length 4.52m Beam 2.00m Hull weight 85kg Sail area main / jib 14.76sq m Sail area spinnaker 13.94sq m RS200 Length 4.00m Beam 1.83m Hull weight 78kg g 251lb Sail area main / jib 11.52sq m Sail area spinnaker 8.29sq m Now thinking about this some more, the challenging bit of rule writing would be some limits to stop it getting too pure an open water shape, you'd want it not to become too flat and wedge shaped and be a reaaonably roll tacky sort of shape. See threads elsewhere!! |

Very much the same, I'd have thought. It's the simple ratios which dominate, not the finer points of design. Which makes it for heavies. Nothing wrong with that, provided it is the intention. The demographics tend to favour boats for lighter weights though e.g. compare the numbers sailing Merlins versus RS400. Lighter weights bring mixed teams more into the frame. |

Hm....how does the Laser fit into that picture? I wouldn't really agree that the Merlin has all that wide a competitive weight range these days either, but it does tend to fit adult mixed teams pretty well.

When you talk weight ranges, don't you have to compare a class to other comparable boats?
That means surely that you can compare the Laser's weight range only with the other singlehanded Olympic classes that have seen 180,000 boats launched, and national title fleets of 100+. ![]() |

I don't get what point you are trying to make, Chris. Bumble argued that the popular classes are those with a wide competitive weight range. However the Laser has a narrow range compared to, say, the Solo. Nevertheless, it is evidently highly popular. |

I agree my argument doesn't look to good. Like all fools in such a predic' I have to say ......'exception proves the rule'. While that may be a cop out, I don't think anyone would argue the Laser has been and is an exceptional class. I beg to differ that the Merlin still carries a good range compared to other boats of a 'similar' type. I think the raking rigs have helped preserve that at least. |

The point is that surely you CAN'T validly compare the Laser's weight range to the Solo's weight range. One is a class which sails basically in the UK and in Holland and does a very good job of giving amateurs like us something to race. To become competitive at the top level, you obviously have to be a damn good sailor. The other is a class which is sailed to world champs level in about 65 countries, many of which have basically pro Olympic sailors. To become competitive at top level, you have to be able to beat Ben Ainslie regularly. The level of competition just can't be compared. The Laser is vastly more competitive. Therefore what is needed (in terms of weight) to be competitive just can't be compared, surely. Comparing what is needed to be competitive in Solos to what is needed to be competitive in Lasers seems a touch like comparing the level of dedication needed to be competitive in some parochial sport like Royal Tennis, to the level you need in a major international sport like football. Or like assuming a local amateur car racing class (like HQs we have here) is as demanding and competitive as F1. Interestingly, the Laser's competitive weight range is wider at Masters Worlds level (which still attracts about 20+ times as many nations as Solo sailing, including ex Olympians who train damn hard). There's a distinct link between the level of the racing, and the width of the competitive weight range. Edited by Chris 249 |

'xactly so. At club level you don't really need to worry about the right weight too much. Interestingly, for all the fuss made about the wonders of equalisation, the only time its been tried in a top international class it was a failure and abandoned. |

Personally I think the best solution may be a semi development class like the 505 or the Swift Solo that I am building. Design a modern hull that is a good compromise between the attributes discussed here and then basically fix this part of the design. The rig would only be limited by agreed max sail areas and prohibitions on hideously expensive materials. This then lets people put on a rig which suits their size and also allows for innovation in the class. The class could be bought off the shelf or people could be free to do their own thing.
