[Public-List] Fire and liners.

[Mike Lehman]

Stephen,

I think you will find the liner to be about 1/4" think and much thicker in 
other places where they add structural support, such as around the bulkheads 
and engine mounts. The liner does provide secondary structural support to 
the boat, but as a headliner not so much. There are many places where it is 
not bonded to the underside of the deck. I think you are fine with sanding, 
and from the look of the pictures, I do not think it would take very much, I 
could be wrong. Sanding seems like your only option.

Hi,

Halotron is only poisonous if it gets really hot.
On a kitchen fire it would be fine. Halon is illegal
in Canada except for the military. I had my old Halon
fire extinguisher confiscated, much to my annoyance.

But going back to the flakes in the liner. Has anybody
seen this before? The liner is not painted, these are flakes
in the fibreglass.

On a related note, what's the deal with these liners anyway?

How thick are they?

How well bonded to the hull and deck are they? In some place
the seem to be completely bonded, in others, no so much.

Do they add any strength to the boat? Put it another way,
how much can I remove without compromising the structural
integrity?

Incidentally, I do *not* want a discussion of the relative
merits of liner vs. non-liner boats. It's been done.
