G'day,

 

Mark and his son had been living and working on it for 5 days, so food and tools and usual gear would have been onboard.  Near enough cruising trim.  How much more powerful?  Depends on what you want.  For most cruisers 15 in 15 is ample. It could probably handle another 30-40% of sail to be compromised.  Depends also on the stiffness of the mast, which is a variable that can be set before launching.

 

regards,

Rob

Whats the windward hull load capacity. In the video is Rare Bird at
cruising trim or light?

How much more powerfull could it get before compromise?
