Hi, we have a problem with condensation/moisture (donīt know the correct word) in our forward cabin. I guess this depends on the fact that the big watertank is placed under the bed. Even though we air it as much as we can we already got mold in the interior.. Does anyone else have this problem and does anyone have any suggestion to how to increase the airflow or in some other way get rid of the condensation/moisture??
 
Best regards,

Do you mean the condensation under the matrasses (there you will find diffrent threads about here in this forum for example this one: http://www.myhanse.com/forum_posts.asp?TID=1598 I used the ikea solution.... works very well), or what do you mean?

We also used the IKEA product and we are happy and everything is dry.

I can confirm this. In the short time we had between delivery of the Yemanja and our holiday my husband installed the Ikea solution. After 3,5 weeks everything was dry and the comfort is ok. Perhaps we also buy a top at Ikea to make things a litter "softer". (we bought a lot more from Ikea for the boat, they have all sorts of "handy stuff")

Just made a few holes
For extra ventilation, also added a few ventilation holes:

I bought Dry-Mat in the UK to put between the wood and mattress.

Gregor, are you still happy with the Dry-Mat? Will it work without the holes underneath, do you think?

We first installed the Dry-Mat type product and did not find it over good. I think we did not help matters, as we had cut it to size (like the photos) and I think you really need it to have exposed edges, so that you get some airflow.
 
WE got an alternative from the Largs Chandlers.  I think the product we now use is
 
 
This is thicker and does not look as nice, but it seems to do the job.  We use it in the back cabins and have not cut it so size, so it sticks up above the mattress down the side and along the bottom of the bed.  After a week, we will find some moisture on the fibreglass base of the bed and the bottom layer of the Hypervent will feel moist.  However, the top of the Hypervent will be dry, as is the mattress.
 
I am actually thinking of putting some insulating foam on the underside of the fibreglass base of the bed, (ie in the lockers) to see if this will eliminate the cold spots on which the moisture forms.

In the forward cabin, the underside of our mattress cushion becomes damp. We control this by placing a large fender under it during the day. Occasionally, we put these cushions in the open cockpit for an hour.
This regime has worked for us during several months of living aboard each year.

The void under the bunk suffers condensation because of the water tank. It's difficult to deal with this, because the solution would be to lag the tank. All we can do is wipe the tank and open the various covers whenever convenient to allow air circulation.

I installed a vent in the hatch to give some air circulation and we keep the cabin door open.
