Title: Ingress of water into the watertight compartments - worry for winter lay - up
Post by: Alf Lande on 28 Jul 2012, 10:13

Bayraider.
I opened a few of the hatches to the watertight compartments the other day, and found water inside. I believe there are water present also under the sole tank....(in cavities?).

The presence of water in these tanks is not a big supprise. But I started worrying about the winter layup with temperature conditions below zoro and the danger of ice freezing between the outer hull and the inner lining / under the sole watertank / inner lining.
(I live in Norway..)

As most people know freezing ice expands a little bit compared to liquid water, and produces a signinficant force that may - over time - seperate the soletank from the outer hull??

Any comments - do I have to find myself a frost free winterlay-up for the Bayraider ?

I think a small amount of water in puddles shouldn't cause problems. It is water trapped in enclosed spaces that can cause damage freezing. If you can get your arm into the tanks you can probabaly use a sponge to get out most of the water left.
