I don't have any personal experience with this stuff, but I think it
consisted of foamed layer of something (probably not "rubber") enclosed between
two sheets of plastic. Even with the foam core, it was pretty limp stuff as
far as stiffness goes - like an order of magnitude less than plywood of
equivalent thickness. The sheeting skins were synthetic stuff and much tougher than
"linoleum." Old Town canoe sold a canoe called the "Tripper" made of something
similar, if not identical. (They called the substance "Oltonar" or something
like that, but I doubt if Old Town developed the stuff independently.)
The stuff has its virtues, but it is a material that requires
full-scale heated molds and serious engineering to fabricate, i.e. its not of any use
to an amateur builder or any small-volume specialist firm. If you want a canoe
built of this stuff, you will be limited to the offerings of a few large
manufacturers. They were intended to compete with aluminum canoes, which also
require substantial plant to manufacture. A boat made of this stuff would probably
be the best choice for a "glory or death" wilderness trip, with an aluminum
canoe the second choice, but for anything other than that, they are heavy, limp
and blunt-ended.
Still, all in all, any canoe is better than most boats, and one that
doesn't require maintenance or indoor storage is probably the best boat that
most of us can have while we're still young enough to really enjoy it. I'd be
willing to bet that either you or your dad, or both of you, got his money's
worth out of that Royalex boat!

The thread reminds me of a question on materials I had the other day,
driving the interstate.
Semi-trailers are covered with what look to be 6'x8' or 6'x10' sheets
of thin fiberglass, riveted to aluminum frames.
Has anyone built with this stuff? I would think multiple chines and an
internal frame would be the thing.
RE: royalex, I browsed canoe sites the other night and paddled canoes
of many kinds. It consists of multiple laminations of plastic over a
core, which expands to foam when heated, at which point they throw the
hot, expanding sheet into a mold to harden up. Hard to scratch. Pops
back into shape after a wrap. Dents pop out if you leave it in the
sun. I wouldn't buy a canoe out of anything else, unless I wanted
superlight kevlar.

Back in 1965, or so...my father purchased an early generation canoe
made that was constructed of "Royalex" it was a product invented by
Uniroyal rubber corporation and was sheets of ultra flexible material
that closely resembles linoleum. I think it actually has a plastic
outside and inside with a rubber composition as the middle layer. The
upshot is a material that gives when hitting objects like submerged
rocks, trees, stumps. It is a little unnverving at first as the
bottom really wobbles quite a bit, but the shape of the canoe is held
by the curves, remaining stiffness, and thwarts.

made that was constructed of "Royalex" it was a product invented by
Uniroyal rubber corporation and was sheets of ultra flexible material
that closely resembles linoleum. I think it actually has a plastic
outside and inside with a rubber composition as the middle layer. The
upshot is a material that gives when hitting objects like submerged
rocks, trees, stumps. It is a little unnverving at first as the
bottom really wobbles quite a bit, but the shape of the canoe is held
by the curves, remaining stiffness, and thwarts.
