We recently bought a 6 yr old narrow boat, we are living aboard, she is well heated and ventilated. However, the boat wasnt well ventilated prior to purchase, our surveyor noticed drip marks on the internal walls of the boat, and put this down to poor ventilation.
We have today noticed that we have some water dripping down the internal walls from the gunnels, it seems as if it is coming from the insulation.
We have had very cold weather over the last few days - snow and ice on the canal, not sure if this is effecting it? But as I said previously we are very careful to keep ventilation maintained.
Does anyone know what could be causing this, what we could do to prevent/ fix it?
Many thanks
