It is good to get your vegetables while sailing.... vertical leading edge - yeah dude - you folk should see the windows, cutters, forks/sticks,scrapers the CA people use out there...that stuff can 'suck you over' to China it grows so fast and strong ! But it makes a nice tea and a decent marinade for tuna steaks on the BBQ. Me - I am thinking of one of those wingding keel thingiees with some tip turbulators for the phosphorescence shows and the tunes blasting Zappa. Take Care,Have Fun,Go Sailing before you cut it off ! it is getting like a blackjack hand - you're sitting on '19', want another card (keel) ? HIT ME BABY !
