If they were discharged significantly and sat that way, their condition and ability to take a charge will be somewhat of an unknown. But I'd be surprised if you can't get at least some of the batteries (if not the whole bank) to take enough charge to manage for the trip home. In particular, being that you'll be motoring the whole time, limping along with fairly limited capacity shouldn't be too hard.

But if all of the loads were actually shut off, chances are they're not all that discharged (self discharge on AGMs is fairly low). If that's the case, they should charge right up and be pretty much fine.

I'd definitely plan to have the boat plugged in for as long as possible while you get everything sorted and ready to go. That'll get the batteries topped off and then you can see what shape they're in.
