Noticed today that my canoe was damaged sometime last year. The damage is in the bow. Hasn't gone through. but we're thinking it needs to be fixed.

It's a kevlar/glass hull from Composte Creations. Any suggestions on repair? how bad is this...we're going on a trip Thursday.

This looks pretty bad -- way worse than just put a temporary piece of duct tape on for the weekend. A quick repair with plastic like RecRepair would be possible -- if you can find a source close at hand. Otherwise I would keep the boat out of service until it is fixed. It looks like it will need some epoxy fill and then glass and gel coat over top -- a multi-day exercise to let the materials set. There are lots of demos on YouTube, including a great one by NovaCraft.

If you use this boat damage you could get water infiltration in the fabric which would be major issue.

Yup I wouldn't put that on the water until fixed. You'll want to dremel it out some to get to clean material before doing any patchwork. But yeah epoxy, glass, but no real need for gel coat IMO. Then when done install a skid plate depending on where exactly that is. But looks like it is toward the bow or stern.

I would not use it as is, even with some quick and dirty “repair”.

A thorough repair, with modern materials and best practices, will take an hour or so a day, spread out over a week. I would:

Sand it. Wash/scrub it. Let it dry completely. Fill the voids (epoxy or G/flex thickened to a near paste). Sand the filler smooth. Cut pieces of Dynel fabric large enough to cover the worst of the stem scratches and gouges. Tape and paper ¼” outside the dry resting fabric. Paint a coat of epoxy or G/flex (or mix) inside the taped area. Lay the fabric in place. Cover with release treated peel ply cut an inch or so larger than the taped area. Lay the peel ply and press/compress on top to smooth out the fabric, the Dynel fabric otherwise will be swollen and rough textured.

I use a 50/50 mix of West System 105/206 and G/flex, and a teaspoon of graphite powder stirred into the epoxy mix

I would not use E-glass or S-glass or kevlar felt; Dynel fabric has proven abrasion superiority and that is the only fabric I will use as skid plate material.

Now the bad news; Dynel fabric in unavailable in Canada. But a CCR poster (Recped) imported several yards to sell.

Duct tape did the job!

I have since done a proper repair so we should be good to go for another few years.
