They are rugged, they are sweaty, they have an enormous length of rope. I feel better already. So, having waved off the rescue 'copter, we now experience how it feels to be towed back to harbour, even if it's over a mill-pond Solent in the mild winter sunshine. "Saved from almost certain safety," pronounces Harry with a twinkle. Weekend sailors have been goggling at us all the while from their pretty little boats - Brineshrimp, Wave Dancer, Ocean Lady. Let's hope they have learned something from all this, we tell each other. Bunch of amateurs.
