The installation instructions for the flooring probably says to glue the
planks together to prevent any water damage, even if you're using the new
snap-lock type. One would assume that in a boat this would be done. I
have spilled a lot of water in my kitchen with no problems on the laminate
flooring. I did leave a bit of water on my den floor for a couple of
minutes, and there is some swelling along the seam, since it wasn't glued in
that room.
