We left Ijmuiden and got about 5 nm out when I spotted a ‘water-issue’ in the aft cabin. When I say ‘water-issue’ I mean there were gallons of water coming in from somewhere. The skipper and I got to and started bailing as the others turned the boat around. We must have done at least 10 full bucket loads and we got back to the marina on the sea side of the lock. After confirming that there wasn’t a fatal leak (we decided it was a build-up of rainwater from the last week) we headed back to sea again, but the winds of 30kn and F6-7 made the crossing a little uncomfortable.
