Hamish,
This is Steve Maynard- Hull # 74 hopefully to be delivered in July.
Matthieu didn't think there was any need for a JDS - so I did not make a big deal of it. We are older, (64 & 60) and would want a way to slow the boat down if we found ourselves in very poor conditions (like Seth on Archer doing 10+ Kts on bare poles all night!). What are you using for the Attachment points? I have ordered an extra cleat on each transom so I have an inboard and outboard cleat - I was thinking of a 304m V Bridle on each transom to a 8m V between the transoms as the best way to distribute the load to the cleats/boat.
