Hi Bob
Are you any further forward in tracing the source of the leak? Since putting the dehumidifier on our 36 Classic we have only had 2 very small amounts of water through the access hole to the deck organisers despite some torrential rains. However, I am now not 100% convinced that it is due condensation in the double skin so will continue to monitor it. I really need to be on the boat when it is raining hard.
Come the better weather I will take the top off the main hatch garage as this is the only area I have not had a good look at yet. I am pretty sure one or both of the bump stops restricting hatch opening too far have been knocked off so water could be getting in through the screw holes.
