Sorry to be a be a bit dim here, but i would like to be a responsible sailor on-line if i can. Pretty much all i know about the real sea is that i'm not keen on any part of it that's taller than me *Chuckle*. Crossing those channels between the various Shetland Islands in a small launch in what i took to be a gale, frightened the life out of me, i can tell you. But i digress. Horns 'n' whistles?. What situations call for how many toots please?. Regards, Brian
