Interesting. Have had to take diversion for summer F10 on three occasions, but all of them were well predicted for up to a week ahead (only the precise force, from F8-11, and centre, varied over the last few days). Whilst have seen extreme gusts in hilly coastal locations, very rare to have a forecast change to F10-11 without appearing as gale, or at least suspiciously very unstable, in the forward outlook over a week.
The two of us on board weere both experienced sailors, with over 70 years of sailing experience between us, both in UK and various other European waters. The way the conditions changed were very unusual and neither of us had seen this happen before or since, but all I can say is that when the windspeed indicator showed 55knts we were glad we had plenty of searoom to heave to in.
