2. Concerns
As mentioned I discovered the problem whilst away on holiday with the family we had 6 days on an Island and the boat was moored for this time.
I do not wish to go into the holiday but it reads here if you are interested

We left for mainland on Friday after Easter and it had been blowing previous days 35-40 knots for a few days but was about 25 knots when we left and 2.5 to 3m sea with 1m chop on top. We had family and camping gear and was well below safe carry limit and in my opinion safe enough to return but with some risk associated so we all wore life jackets for the 20km one hour plus trip to the harbour from near Great Keppel Island.
I thought the trip went okay but the boat was not too responsive - never broached and I took it easy sitting on about 17kph and letting the swell and waves pass us by as we were going with the sea at about 45 degrees. I let the boat drag it's tail and never tried to go faster than a wave or use the trim tabs - it was okay but the sea was pretty big and very brown.
We got back okay and I put the boat on the trailer and then removed the bungs.
Here I need to describe how the boat is designed - it has three separate airlocks front to back and the middle one has a bilge pump - the outer compartments have no pump.
The Port side compartment drained hard through the bungs for over 20 minutes and the Starboard compartment for over 10 minutes. I reckon one airlock was full and one at least half full. The middle compartment with pump was empty.
If I'd had any idea I was returning with my family in a laden boat with the sub floor more than half full of water in that sea!
I am taking steps to ensure this doesn't happen again - see in Repairs.
Some may say it was my fault for not checking these compartments but there is no way to check them at all.
