Important note:
Suggested boat sizes are given as a guidance only and assume a monohull with boom end sheeting, loaded vertically to the traveller.
Mid-boom sheeting, severely angled take offs and curved tracks can impose greater loads and suitable allowances should be made for this. If at all unsure of your choice it is important to seek further advice. If you are close to the maximum boat size suggested, we would advise upgrading to a Torlon package, long car or the next size up.
