This little table was written for the US version of the West Wight Potter shows how very rapidly the pressure on a sailing rig rises with wind speed in mind – and similar tables could be drawn up for other sailing boats.
It comes from Many Ways to Potter, a handy guide to sailing these little centreboard sloops that includes lots of good advice for those sailing other small boats, including on how to manage in strong winds and rough water. Read it here.
Thanks for pointing this one out Paul Mullings!
