It is important that you as the Crew know what to do, after all the Skipper almost certainly doesn't. Skipper has desperate hangover. Looks hopeful that racing is cancelled. Requires firm but sympathetic smack to the head with the heavy weather racing boom to bring to racing mode. Usually accompanied by pleading look, white eyeballs, nervous stench and whining voice.
Skipper has severe cold feet.
Surprisingly not a cricketing term nor an invitation to bail out. Serves no other useful purpose than to let the Crew know that the skipper is smugly hooked up and fully stretched out on the wire after tacking without warning. Implication is that crew should extricate himself from an intimate embrace with the leeward shroud so that Skipper can devote his superior intellect to contemplating a complete tactical plan for assuming control of the race. Skipper has triumphantly found the only hole in the wind in a raging 30 knot southerly and aging legs have ceased to function as boat rolls to windward. The ideal Crew will climb hand over hand along the bungy cord from that familiar windward trolling position he has been cast to, in vain attempt to prevent capsize.
