Bottom Saver for a SIB ?

[Squid Boat]

I was given a 11' Bottom Saver strap-on and was wondering if anyone ever used one on a SIB, or remembers them? I'm assuming that it is molded fiberglass, but not sure.It weighs about 14kilo.
I remember seeing ads in boating magazines 25 years ago, but I have ditched my old mags. I might save it for my Zodiac Mark 1 GT or use bits for a removal-able bow dodger on my Avon 4.5 CRRC.
Thanks in advance.

Cheers, Squid.
