Alumacraft Lunker 16' Foaming Locations

[84Prostar]

Hi - I'm rebuilding this Alumacraft Lunker V16. I'm trying to decide how much / where to add emergency flotation foam (2lb expanding closed cell). Candidate locations are in the attached photo. I'm wondering about:

• under the decking. concern is that a lot of water will be passing through here, however my thought is that some foam would help with comfort, stability, and vibration absorption
• in the other locations identified by the photo - these should be easy enough

Opinions here?

If you think a lot of water will be under the deck and cause waterlogged foam, fix the leaks before foaming.

You can't go wrong with foaming as Alumacraft built her. They knew what they were doing.

Thanks. The under-deck water is because the boat is outdoors all summer without a cover

There is a fix for that.
