Some time back I entered Salcombe harbour in the UK single-handing my cat and with some difficulty I picked up a mooring in a fairly strong wind over strong incoming tide situation. Soon after attaching my bridle to the mooring buoy it was facing aftwards with the mooring buoy knocking on the inside of the hulls.
Increasing the water resistance by lowering my daggerboards had no effect, I ended up by first towing a bucket and then also a big folding plastic crate from the cockpit.
Has this happened to you and what was your solution?
