In the high teens is the extreme that many owners have seen on tranoceanic passages. So yes they would be laden and either way far faster than I personally would want to go. A friend who is a yacht designer
was seeing that their speeds during a Cape to Rio race
were about the same as a farr 40. I personally think though that the extremely high speeds are not as critical as good speeds in low winds, which is the majority of passages. I do know that I can do around 6 knots in 8 knots of wind
, which to me is excellent. If the boat has narrow hulls, and the st francis is 11 or 12 to 1, and has a lot of sail area to displacement
, which in the st francis is 1200 sq ft of sail pushing a 15,280 lb boat (optimal light ship displacement), it means you will be moving very well. And yes, there are catamarans today which are literally twice the weight of our boat and less sail area. Because our hulls are so narrow though, we definitely have to be very careful in weight, we don't carry a generator
(we are entirely solar
powered), we carry a light RIB
, we always watch our waterline.
