Quickstop COB recovery
Re high-wind quickstop: I was taught that this is a technique that should only be used when sailing close-hauled or close-reaching if the wind is up ("up" being a relative term depending on your boat). If you''re beam- or broad-reaching in high wind, the reach-on-reach or figure-8 is safer.
In theory I can see how you''d do this starting from a deep reach: immediately head up, then cross the wind (foresail backed) at the point where you reckon the wind will push you down onto the COB. However, in high winds you might also have high seas, and if so you don''t want the piching boat to blow down onto and on top of the COB. In such conditions you''d want to have the COB to windward--easier to do via reach-and-reach.
I''d also consider dropping sail and motoring--just remember to go to neutral well before you close with the COB.
