condensation problems

[oak]

Any one else suffer from condensation problems in particular behind the quarter birth back rests.
If so how have they dealt with problem.
I have fitted a deck ventilator and vent in the washboard which keeps the rest of the boat dry.
Has anyone lined this area?lots of condensation also inside around the engine well?
any helpful suggestions welcome as I don't think my boat is unique.

Following up on this post, we had lots of condensation inside the boat too. I think its unavoidable given the lack of insulation on the hull. The only answer seems to be good ventilation, wiping up and airing he cushions. I looked at a product at the boat show which is a sort of stiff open cell foam, intended to allow airflow and prevent condensation behind cushions, but some people who have it (on a larger boat) say that it makes little or no difference.

How about silica gel in bags to absorb the moisture? It can be refreshed by drying out in the oven.
I've been considering buying this for the same reasons -

I reckon 3kg spread about in 3 or 4 cotton bags should be enough to keep a CC dry

I bought two chemical de humidifiers from Home base

Left the boat over the winter and was really pleased with the result. Dry and mould free..
worth the money I would say.

Dear all,

Thanks for the suggestions so far. We're planning a ventilator forward in the hatch with one in the main hatch as well.

As far as damp in the quarter berths is concerned, our previous boat (Pippin 20) had a small circular stainless steel vent right at the stern of one of the quarter berths, venting into the inboard vertical face of the cockpit coaming, i.e. next to the engine. We might add a couple of these.

Ex several boats!

We have yet to fit a deck vent up forward. Has anyone done so, and if so, where on the deck?

I wondered about putting one either just forward of the forehatch, or in the anchor well. My concern about the anchor well is that the ventilator may end up under water in a big sea or if the drains block when the boat is at anchor during the autumn!

Kind regards,

Adrian and Roger Langford

Hello Adrian

Have a look at Ladybird's album. It is fitted with a vent. I do know that others have also fitted vents in the cockpit sides near the foot of the quarter berths.

Not a good idea to fit anything in the well, for the reasons you give. Mike Brooke in his book " Theo's Future" gives an excellent account of the problems that can occur when you take big green ones over the bow. If you have not read it (yet) see me, Mike gave me some copies at Mylor to bring up north to sell in this neck of the woods.

Congratulations on the boats new name, "Meisje". But how is that pronounced?

We have lots of experience of sleeping aboard. Condensation is only a problem for us if more than two sleep aboard. We looked at and discounted the under cushion mats, thinking they would not help on such a small boat. I diligently wipe all the surfaces in the morning and air the cushions each day. We put the cushions in our sunny conservatory between trips until thoroughly dry. I also fold the back cushion down on top of the seat cushion (so they are in two layers); I think this means that condensation is less likely to soak into the cushion, as well as giving a little more space in the berth.

I get condensation under the cushions on Lucy. However, I don't get condensation if I sleep with a camping mat between my body and the cushions. This makes perfect sense; the sea keeps the hull cold, and your body is warm - so keep them apart with a closed cell foam mat.

Looks like a Dutch word meaning "little girl".
