The average all-up weight of the crew is 14683 kgs which means that 3 of the crews were on the money weight wise and the range across the top six was only 30kg.

J70 ideal crew weight. In steady boat speed type conditions the optimum crew weight is over 400 lbs. Large mouth Gennaker launcher. The class rules comprise the official Class Rules document as well as the current Building Specification.

Big range from 50kg to 90kg due to advantages at each end of the scale. It adds more logistics finding that fourth crew that I was hoping to avoid with the J70. A variance of 4 to 20 kg per boat seems significant and why are all American made 70s light of the one design specifications seems like a long term fiasco like the 105 issues of scrimp versus pre scrimp TPI versus US Watercraft and Hall versus Sparcraft.

Stepping the mast and rigging up to launch can take an hour or less once your crew has learned the routine. The International Technical Committee maintains a Frequently Asked Questions FAQ document which provides interpretations explanations and clarifications of the rules where needed. The optimal weight of the crew ranges between 100 to 145 kg making it a suitable boat for men women and youth teams.

The 11 long cockpit and moderate height boom in the J70 allow easy crew movement across the cockpit while tacking and jibing. 42 m 13 ft 9 in LWL. Single line Gennaker halyard retrieval pole launcher.

5897 kg 1300 lb LOA. Recessed Harken Jib furler. Again the biggest variable was crew weights.

95kg is a good weight for an OK. 0787 m 2 ft 70 in Hull. Light - get on foils earlier.
