Yes. You can tell because the hull is a five-layer laminated sandwich of vinyl-ABS-ABS foam-ABS-vinyl.
Probably Royalex, could be another type of sandwich construction.
Remove the deck and replace it. Try some Gflex in a small spot on the bottom of the hull. See if it sticks.

Gentlemen,
I've redone the gunnels and inwalls and made new decks and lifting handles. I'm not installing the decks until I solve the patch issue on the bow. I will varnish all of that and the seats once I'm done with the hull and patch.
First Issue: Please take a closer look at the bow picture where the patch is. Are you saying I should peel that down until I hit boat and then try to fill with gflex or put a skid plate over it? I haven't bought the gflex yet as waiting to know that's the better possibility.
Second Issue: I note when the boat gets scraped on my wooden horses some red comes off on the horses. What can I polish the hull with to remove oxidation and then protect it with a coat of what?
Very humble over here so jump right in. Bill

Those look like Mad River decks in your pics. Mad River Royalex hulls with wood gunnels that have been neglected for long periods of time always give me pause. Have you checked thoroughly for 'cold cracks' before you proceed? They would appear as small cracks in the hull emanating from the gunnel screw holes. Here's hoping you are okay.
Your hull looks pretty red to have much oxidation. I would make sure that it has not been spray painted. If not, repeated rubdowns with 303 Protectant will help the vinyl. Some color will always stay with the rag if it has not been done in a long while.

It's a little hard for me to see from the picture but you say that it looks like a previous repairer might have used Bondo...
I'd pick off anything loose and start sanding (actually, I'd start with a rasp but I lack patience), both to smooth out the area and to expose the previous repair. If someone did use Bondo: 1) I'm a little surprised that it stuck and 2) I'll be even more surprised if the G-flex sticks to it.
You'll have to make the call based on how securely the patch is bonded to the hull. If the previous patch looks firm, smooth it up and maybe try testing adhesion with a few drops of G-flex (applied, allowed to set up and then see if they are stuck). Hopefully, you'll have to sand off those drops instead of them just popping loose. If that's the case, proceed with skids & call it done.

If it's bonds, it should shatter pretty easily with the tap of a hammer. If it's thickened epoxy, not so much. I would clean it up best as possible, then use thickened epoxy to level everything out, sand it and patch it outside and probably inside.
It looks like whatever they used to fill gouges was left proud of the hull. If that's the case, I'd carefully file it down close to even with the hull. Then I'd put a skid plate over it. Gflex and fiberglass are my go-to for that.
As far as the color rubbing off - washing and waxing (with a plastic friendly wax) will help with oxidation. It's unclear to me if that's what you're talking about though. The outer vinyl layer of royalex is not abrasion resistant, so anything hard that rubs against it will collect some of the color. Anywhere royalex canoes are common on bony stretches of river, it's common to see the rocks "painted" with red, green, blue, yellow, white, etc everywhere the rx canoes have scraped
Oh, as already mentioned - if it turns out that is bondo, I'd chip all of that out as much as possible and start from scratch with thickened epoxy. JB Weld also works.

True, thanks mem, I hadn't thought of that... thickened epoxy would probably look a lot like Bondo (but certainly act differently)
Like flagging tape that doesn't wear off. (sorry, Bill, I have no insight into the color coming off.)
