Thanks for the reply Matt,

It sounds to me like I may be worrying too much about this with the Hobie. In many other designs of boats this can be a very serious issue.

As you know, it doesn`t take long for several ounces of condensation to collect in the hulls. And, due to my particular storage situation, I am forced to leave a small amount of water in the hulls to freeze. The interior geometry of the hull does look as though water should safely expand upwards as it freezes. In addition, unlike other boats, there are no stringers or bulkheads for entrapment.

Still good to have a little reassurance.

Thanks


Dave
