Hi Simon
Here are the numbers (some are my estimates but should be good enough).

1, No of crew - Cat 1, Sloop 2
2, No of crew on Trap - Cat 1, Sloop 2
3, Min Weight of the boat incl sails etc in KG - Cat 85kg, Sloop 95kg
4, Overall length - 4.9m
5, Max Beam - 2.185m
6, Max mainsail and mast area combined - 13.4sqm
7, Vertical luff length of sail (luff len will do) - 6.9m
8, Jib Area - 3.3sqm
9, Vertical luff of the jib (Luff will do) - 3.8m
10, max allowed Spi area - 14.2sqm
11, Max authorised board area - .23sqm
12, Max allowed depth below the hull - .77m


The centreboard size has been reduced over the years on Mosquitoes. The measurements I've given are the maximums possible in the rules but in reality any boat built in the last 10 years is using boards which are much smaller than the maximum.

Similarly for the spinnaker, the size I've shown is the typical spinnaker size we are currently using and is less than the maximum possible. There's no maximum area rule and it would be possible I'm sure to make a bigger spinnaker that would fit the measurements. But the reality is that over the years of spinnaker development, smaller ones have proven as fast but easier to handle. Some Mozzie sailors believe we could make the spinnaker smaller still without losing any performance.
