Entered the Cardiff (UK) sea lock with a strong following wind and failed to get the stern warp on. Bow warp secured so I just went sideways across the lock. The lock was 30 feet wide and the yacht also 30 feet. Being a Sunday there were about 50 spectators. The control captain came to my aid with a megaphone giving instuction to use full rudder and lots of power. Got alongside and secured after a struggle. Control gave me a generous 4 out of 10 for the approach and 8 out of 10 for the recovery.
