Well, "Carbonlite" (which is marketeering for polycarbonate, like Lexan)
is a nice material.  However, the price is closer to fiberglass than
polyethylene.  The full size Carbonlite kayaks run $1700-$1900 new.  The
weight, however, is about midway between polyethylene and fiberglass.

So, kevlar is substantially lighter but more expensive.  Fiberglass is a
little more expensive and a little lighter.  Polyethylene is
substantially heavier, but much cheaper and tougher (but can't be
readily repaired).  Polycarbonate lies pretty much within the
cost-benefit envelope, leaving no clear-cut winner and making the choice
personal.

Eddyline does tell you that its labor cost is low -- much closer to
rotomolded polyethylene than the composite boats.  An interesting thing
about these boats is how even Eddyline gets the thickness of the
material.  They don't seem to discuss their process at all, though.  My
guess is they spray the plastic into the deck and hull molds.

I demo'ed the Eddyline Night Hawk in Carbonlite 2000 this weekend--great
boat!

It's 16' long, 22" wide, and 48 lbs.

With a drop skeg, it is easy to counteract the tiny bit of
weathercocking, and with it all the way up, oh boy, is it ever nimble! 
My buddy had his 16.5' Perception Chinook NW, and I kept having to stop
to let him catch up.  I'm a devoted wood boat paddler, but I would put
this boat near the top of my short list if I were in the market for a
synthetic boat.

Carbonlite is reported to be pretty tough, but I was reluctant to test
that property on a demo boat!  It's got an available cement for doing
repairs--supposedly much easier than repairing a polyethylene boat.  It
is certainly light and stiff, though.

A friend bought a merlin a couple of years ago and shortly after wards 
dropped it by accident on a piece of lime rock or some such-- anyhow- the 
carbonlite did crack-- BUT- it was a pretty good blow, and it did repair 
fairly easily!!! The carbonlite really seems to be a good answer to hull 
rigidity-sharp lines at a reasonable cost
my two cents

The full size Carbonlite kayaks run $1700-$1900 new.

The sixteen foot that I was interested in, the NightHawk, was selling for 
$1450.

I have some experience with Carbonlite repairs.  The first time we cracked 
one of the Merlins, Eddyline sent me some Merthacrylate (Sp?) glue, which is 
what they spec for all repairs.  The glue is truly tremendous for many types 
of repairs.  A cousin of Cyanoacrylate maybe?  Dave, what can you tell us 
about this Vundergoo?  

At first, I tried the repairs without instructions from Eddyline.  I gouged 
the cracks on one side into a "V" notch and filled them with the 
Merthacrylate, then tried to work the glue into the unmodified cracks on the 
opposite side.  The first few times the boat was used, the cracks disjointed 
again.  

After contacting Eddyline for instructions, I re-did the repairs their way, 
saturating a strip of fiberglass tape with the Merthacrylate and applying it 
over the cracks.  We used the boat extensively after that, without further 
failure of the repairs.  However, we had already stopped using the Carbonlite 
boats in rocks, caves and all other rough-use situations except bay rentals.  

The same boat later came back for repair because the keel had been 
dragged-through on the sand and gravel beach where the boat had been 
stationed.  There was a 4-inch long hole the width of the keel at the point 
of maximum (fore/aft) keel radius, and the plastic was thinned beyond.  I 
filled in behind the opening with thickened resin, then covered the hole with 
the same tape/Merthacrylate patch.  The patch seems to have reasonable but 
not great abrasion resistance and seems to be holding up OK.

Overall, I think the material is fine for light use where you want something 
that is light, rigid and fast.  But I think composites (fiberglass, etc.) are 
stronger and more completely and successfully repairable.  Both composites 
and poly seem more durable and less easily broken when boat meets rock.  And 
I admit that I am still skeptical about the long-term durability of the 
Merthacrylate repairs.

One other thing -- the repairs all looked like yellow Band-Aids.  They lie 
full-thickness on the surface of the boat, very obvious and (if on the 
outside of the hull) protruding into the flow of water.  On the opposite 
side, the crack is still fully visible, looking just like a tight crack in 
any of the other hard plastics, such as acrylic.

Hope this helps,

Harold

Not much, except that it sounds like the monomer for polymethylmethacrylate
(aka Lucite, Plexiglas -- both trademarks), would be similar in action to
cyanoacrylate glues (aka "super glue"), and probably about as strong as
Plexiglas.  

Could be it is "methylmethacrylate?"

> Hope this helps,

Sure did.  Sounds like you have a system that makes Carbonlite
field-repairable.  I'm impressed with the use you have made of the Eddyline
repair system.

Thanks, Harold, for the authoritative response.

I did a bit of a Web search, and it is actually called "Methacrylate" 
adhesive.  The stuff Eddyline supplied was from Devcon, but Devcon's page 
lists a number of formulations with differing characteristics and I couldn't 
tell you offhand which they use.  There are many manufacturers or sources it 
appears.  If you would like to learn more, search +Methacrylate + adhesive.

Happy paddling,
Harold
