Aussiecat,

From Col's reply you can see that there are allot of variants which relate back to the general build tolerance bands.

It would probably be a good idea to start with the Mosquito rules located here: http://home.vicnet.net.au/~nmcca/doc/Mosquito_BRR.pdf
and measure your Mozzie against these documents.

Just keep in mind that there will be some things you can't change on your Mozzie such as beam locations but there will be things that you can change such as centreboard width that will adjust the centre of effort. If you are making a new mast then you can also make it work better for your weight range.

Regards,


Peter
