Congratulations on your purchase and welcome to the gang.
My experience of DP8010 (though I actually used an identical Scotch adhesive with, I think, a slightly different cure time - possibly 8050) is that this stuff really adheres well to the polyethylene of the Hobie hulls. In fact I have used it for various other difficult bonding jobs and as far as I can tell it will stick just about anything to just about anything else with a very firm bond (I believe that the correct technical term is "sticks like sh*t to a blanket"

).
So personally I think that it would be well worthwhile trying some sort of preventive reinforcing job on your boat, the cam columns and drivewell area being the obvious candidates for such attention. Where to reinforce the cam columns is pretty obvious (i.e. encase them for as much of their height an circumference as you can). Where & how to reinforce the drivewell is a bit more tricky because there's a lot of area there and from what I have read cracks do occur in several places, in particular where the drive contacts the hull i.e. (and personally I would address these in this order) where the front end of the drive rests on the inside of the drive slot; under the cams; and where the rear end of the drive rests on the drive slot. I believe cracks can occur elsewhere round the drivewell but these would seem to be the most common sites. Another area worth consideration but probably a lot harder to get to from inside the boat is the cart scupper holes - cracks here seem to have been a reported issue. Dunno if reinforcing these with DP80x0 is feasible but if not you might consider a cart with pads rather than one that goes through these holes so as not to put any more stress on them than you have to.
The DP80x0 is expensive and you might end up having to use quite a bit depending on how far you go with your efforts, but it will probably not do any harm... of course you won't know whether or not it is doing anything to help unless you get a crack but you might get some peace of mind out of the exercise until that eventuality occurs and at least you will feel like you did your bit to avoid the issue.
