dripping melted plastic onto the crack will not work unless its flaming while dripping and stays lit for a few seconds after it lands. The plastic
where its cracked has to be melted also.
Try dripping burning plastic on the crack and also using a hot knife or soldering iron Remember both serfices have to be melted to adhere.

Pelican kayaks are made of High-Density Polyethylene (HDPE) which they also call Ram-X. Coleman makes some of their canoes out of the same stuff.
Plastic welding is the way to go, apparently, especially since the hole is where it will be abused again.
Good luck!

Shari, Shari, Shari....
Your slip is showing again 
My experience with hot knifing (years ago, mind you) is that it is very risky. Too hot and the repair just explodes and goes up in a big cloud of
smoke....no seemless joining of the two parts... ; too cool a knife and the product doesn't reach the point where it will start to "work" and adhere
to or modify anything....
Don't believe everything you think....

If the kayak is of the roto-molded plastic variety (our Ocean Kayaks) then it will be difficult to repair worn-through spots. We bought a rental
kayak years ago that was dragged across the sand during its rental life. The kayak mfr. told us they cannot be patched. Your method of "hot welding"
may work as long as another hole or thin spot does not develop. Consider some transport wheels from house to waters edge to avoid dragging through
sand.

I sacrificed a clothes iron to repair our sit-on-top Ocean Kayaks after they flew off the roof of our camper and in to a canyon near Santa
Rosalillita. This was the repair method recommended by O.K. 20 yrs ago anyway.
No holes, but it worked well to smooth out the chunks that were removed and got rid of the scratches. Sorry Bob, I can't tell by your picture if this
would work for your problem.
We still have those boats and they've taken a lot of abuse.

Not sure if this would work for you but I recently had to repair a plastic boat and the only thig I had was some poly rope. I lit the rope on fire and
let the drippings fill the hole. It sealed out water but probably would not work well if the repair was in a high stress area. Good luck with yours.

Hi Bob, Before I retired I used to have a business where I would have to weld different types of plastics. I think that most hulls are thermoformed
from a combination of polyethylene and polypropylene, or a copolymer. These plastics are all of the polyolefine family, meaning that they are a wax
based plastic using either ethane or propane gas in the manufacturing process (hence polyETHylene or polyPROPylene). The wax base prevents gluing, but
you can weld it. If you can place a patch of similar copolymer(most are 3 to 7 percent PE to 93 to 97 percent PP) plastic on the inside and hold it
into place while welding if from the outside, it should make a patch that can be drug over the sand and not re-split. A cheap (about $29.00 when on
sale) plastic welder can be found at Harbor Freight, and you can cut your own welding rod from stock about 1/8" thickness. You'll need a compressor
for the air supply while welding, and let the "torch" cool down before turning off the air (READ THE MANUAL!!!). Any ?'s U2u me. Buena Suerte,
Paul

Use a Petex stick intended to fix polyethelene snow ski bases.
A hot flat bladed screwdriver helps to "Weld" it. A petex gun that any ski-shop has makes it a easy fix.
Real bad holes require a hot air welder, also available at better ski repair shops.
Use a piece of another old kayak if you cant find Petex.
Old melted army men and melted styrofoam cups are supposed to work also

I think BJ is on the right track, however, one would have to heat the yak surface with a heat gun first.
The BIG problem is that the yak and the repair product expand and contract at different ratios than the plastic on the yak. That is why Hobie Cat will just give you a new hull under warranty no matter how long you have owned the yak.

No, you dont. You can, but you will blow a hole right thru the kayak with a heat gun if you are not careful.
Use the red hot flat bladed screwdriver to pre-heat the edges of the repair before melting the petex candle on to the kayak.
Use the red hot blade to "weld" the repair together.
I have fixed quite a few kayaks using just a petex stick, backpacking stove, and hot blade, including repairs "on the beach" in Baja. (I used to work
in a little kayak shop on the central coast of CA.)
The "Best" fix is by using a hot air plastic welder.
