Have no current involvement, but was a Sea Scout in the late '70s and a Sea Venture Scout (as they were called then) in the early '80s.
I was fortunate enough to grow up near the coast, and Sea Scouts taught me everything from my first bowline to tides and weather. We only had canoes and gigs at the time, but occasionally ventured across the Solent, and used round-nosed Bat canoes for the surf between Bournemouth and the Chines.
I have often considered being involved again, but my job would only allow ad-hoc support. If you are ever in Dorset or Devon, and require a volunteer, let me know. I owe a lot to the Scout movement, and would love to give something back...
Happy when wet!
