Anyone who's paddled with me knows that I need as much advice as I can get! But I was once on a non SOPT trip a few years back with a chap, who from the moment I stepped into the boat till the end of the trip ......(about 12 miles worth on the trent) did nothing but "coach me" spoilt the whole trip for me on what was a very passive stretch of the river.
I will say this though, regarding safety in construction there is a "don't walk by" ethos.......if you see something dangerous its your duty to point it out. Seems to be a good ethos for canoeing or life in general. Although I dont think this was the intention of the original post which was about being given tips on technique from "experts"
Recently on a trip on the Derwent, Orange Dog told me not to recross the current with Pipster hanging on to the back of the boat (he was having a dip) eminently sensible advice that was needed at the time. But the only other time on that trip he offered advice was when I asked for it regarding eddie angle.
