Sealine Core Material

[presleyjuanita]

We own a 2000 Sealine F44 in St. Thomas USVI. Unfortunately, she is a survivor of Hurricanes Irma and Maria. Since the storms she is listing at least 3 inches on her port side. Theories from 3 post storm surveys indicate the the Hull has been comprised and she has absorbed water into her core. Can anyone tell us what the core of our boat is made of foam or balsa or something else?
TIA

Bump. Sorry I can’t help, but there are many Sealine experts on here.

I'm no Sealine expert but I didn't think their hulls were cored. List is more likely to be something innocuous like additional equipment added to one side.

Normally they they had no core in the hull, they were spray laid into mould, they did use foam cored stringers for engine mounts or stiffening the hull locally. They used box section mouldings bonded into the hull to give flat areas for internal fit out.

So check stringers egg box under floor moulding for trapped water. All above may be waste of time as they used a very advanced vac-bag moulding system for a period around 2000 that I never visited.

I’d be looking for water trapped in areas that are not obviously accessible, e.g. underneath the engine bay liner or other covered areas where you aren’t actually looking at the hull base.

The hull of an F44 isn’t cored below the waterline.

Worth asking on the Sealine Forum - lots of friendly, knowledgable owners but also links to some resources that could be helpful.

I have seen a few drilled Sealines in the past and they had PVC cored hull sides and super structures. Without going model specific I think it is 90s onwards
