Erm, that is if you HAVE the option of taking the spinnaker down! When we shot through the northern reaches of the sound of Jura in a 30 foot monohull, the spinnaker was jammed at the masthead because someone had knacked the top pulley (don't ask!) The inevitable sound of tearing sail was met by a resigned sigh from the skipper and the never forgotten quote "if you don't wreck a sail you weren't trying hard enough"!
Oh, and don't mention the fact that we had been rowing all night because the winds in the southern reaches of the sound of Jura simply disappeared!
What a brilliant, stupid, exhilarating, life affirming event!
