Bit unfair ref RYA chap saying 4 to 1 They only carry out RYA instructions. human error is not accounted for only that those going to sea must use their heads even after an RYA course that gives them an excellent insight into what they have to do. It is however only an insight like your mountaineering instruction. it is ony when you are out there or in your case up there that you can hope to use what you have ben taught. Sometimes teachers do put it over badly for what ever reason but you're the one with the responsibility and what ever happens you have to drop anchor and wait to see if it drags then lengthen the rode if it does or you may be too close to shore or the guy next door or the tide is dropping further than you thought. It's not nannying because what happens to you when you're doing the stuff is not always going to be covered by what you were told in the class room. You will however know which knots to tie or try IF you (whoever) listened.
I would guess that the majority of boaters, all kinds, went out there with little knowledge but muddled through getting the experience in as they went. We know numerous people who have been sailing for donkey's years who have only just decided to do a course in navigation or don't want to and rely on chart plotter. One has, after 25years, oly just learned that you should sail by tell-tales for best performance and doesn't know how to navigate but follows the arrow on his GPS! He has survived thus far like many others! Some texhing has to be better than no teaching and the more that are taught the better. if it's affordable they will take the course, if not they don't. It was an elitist hobby, now a huge number can afford the boat but won't or can't afford the RYA course. I'm sure plans are afoot and hope they can be given a nudge.
Hey! I just thought. i knew a chap in Dorset years ago. he was 72 or so I think. Joined the RAF les than 6 weeks training - up in a Spitfire. Come on chaps. Best of British Let's not promulgate the nanny state (EU) straight cucumbers and all that!
