@legumancer @whalecoiner @zoe The 23 footer came with an ancient 2 stroke outboard in a well, that died soon after we got it. Could only replace with 4 strokes because pollution laws, so the one that would fit was woefully underpowered.
We had a mooring buoy in the estuary for a few hundred quid a year. The tides could run at 5 knots. There is no way our engine could fight them, so if returning to our buoy on a spring ebb, we either had to sail onto the buoy or, if not possible, lasso it on the way past.
One day we missed. Had to be rescued by the club motorboat, otherwise it would have been drop anchor and wait about 3 hours for the tide to slacken.
We really didn't know what we were doing. Went and took lessons from proper ocean sailors.
