Sounds very familiar.....!
I also live in South Devon, and use any excuse to get out on or in the water.
My missus keeps telling me that I have too many toys, (Never...!
) and that I should have been a fish, as I spend so much time out there.
Stand up paddle board.
Spear gun and snorkel gear.
I was bored a while ago, so me and a mate, made a contraption to tether 2 of my kayaks together, and we put a Mercury 2.2 on it. It worked quite well, and we had a laugh testing it....
