ABS Royalex Royalite durability question (age)

Fellow paddlers;
I have the opportunity to acquire a 10-year old Swift canoe made of
Royalite. Apparently, it has been kept in a Canadian garage when not
in use.
Assuming that the boat is otherwise structurally sound, I am not sure
what to expect in terms of durability of the material it is built
with. Does Royalex/Royalite deteriorate noticeably over time? Put
another way, would a 10-year old boat have lost anything solely due to
age?
Thanks in advance for any thoughts or experiences you can offer here.
Keep on paddlin',
Michael

Short answer: no.

Longer answer:

1. Check alignment - visual is ok for this, I think. Mostly, I'd be worried
about twist from improper support during long term storage. If it's on
sawhorses or a decent looking rack, I'd tend not to worry too much about it.
If it's leaning up against the wall on a gunnel, I would.

2. The vinyl skin on the outside of an ABS boat will deteriorate under UV.
If the boat was stored in the sun for ten years without 303, it should look
like crap. This isn't fatal if the price is low enough.

3. Check wood gunnels for dryness or rot. Even if the boat was stored under
cover, ash parts might be subject to fungal attack if they haven't been
maintained. Check with Swiss Army knife when owner isn't looking.

My Old Town Tripper is 15+ years old, and I know others that are about the same.
No problem with ABS if it is stored out of the sun.

Of course, you specify a Canadian garage, and that may be constructed to block
snow but not sun, although mine does both!

Mine was old when I bought it in 1988. I even stored it in the sun.
It has been reconditioned by the people I gave it to in 1999 (though
it was still carrying me on many weekends per year. I had a newer and
prettier boat). I do advise keeping it out of the sun, but Old Towns
are really durable. If I'd had a clue, I'd have popped a tarp over it
on a frame, but by the time I knew about sun, it'd gone so many years
so well that I just let it be.

Short answer: no.

Agreed.

Longer answer:

1. Check alignment - visual is ok for this, I think. Mostly, I'd be

sawhorses or a decent looking rack, I'd tend not to worry too much about
it.
If it's leaning up against the wall on a gunnel, I would.

The alignment is a product of the gunnels...the ABS has almost no integral
strength. I once changed the rails on my (at the time, 15 year old) Blue
Hole 17A, and when I popped the gunnels off, the unsupported ABS body was
like a big piece of lasagna. When I put the new rails on it, it was a total
facelift! The boat had perfect lines, like the day it came off the mold.
The only thing it didn't fix was the oilcanning.

2. The vinyl skin on the outside of an ABS boat will deteriorate under UV.
If the boat was stored in the sun for ten years without 303, it should
look
like crap. This isn't fatal if the price is low enough.

Agreed: if exposed to the sun, the vinyl skin will get all spiderwebbed and
could be flaking off. The ABS layer underneath is very susceptible to UV
damage, so check it for brittling if the vinyl has flaked off at all.
However, 10 years is not all that much sunshine in Canada, so if there IS
spiderwebbing with no flaking, then just lay on a coat of marine paint. If
there is flaking and brittling of the underlying ABS, pass over the boat.

3. Check wood gunnels for dryness or rot. Even if the boat was stored
under
cover, ash parts might be subject to fungal attack if they haven't been
maintained. Check with Swiss Army knife when owner isn't looking.

Especially check between the ABS and the ash rails. Thats where the moisture
collects; remember, gunnels rot from the inside (against the hull) out, not
from the surface down.
