That is a bit. However it is definitely the boat as we have had to go through them all and get them individually licenced (I was not involved so don't know details). Seems very confusing when it also mentions members. Maybe it is different for Kayaks/canoes as opposed to a club licence?
All our boats can only be used if a rowing club member is in the boat (or supervising from the bank for singles). I am not allowed out on my own in a boat as not deemed competent yet (only started rowing in May).
My son is competent but under 18 so he is also not allowed out unaccompanied although I can be the 'responsible' adult with him
(although I have to cycle with him, he refuses to row with me as I am so rubbish
). The club is actually quite strict about safety, rightly so, as it impacts the rowers, the expensive boats and other river users!
I do see a lot of kayaks and canoes when out for a row so there must be a club nearby. Might be worth joining them as there will be a social aspect and help with legalities.
