NJ Boating/fishing regulations question

[bulletbob]

Here in NY we have no "safe boaters course" or certificates that go along with the course.. We have it for personal watercraft only here, not motor vessels.
Now, I have rented motor boats in NJ for fluke fishing, and was never asked for any certificates... So if I trailer one of my own boats down this summer, and am stopped by the CG or NJ marine Police, am I in trouble??.. I could I suppose launch out of Great Kills, and avoid this problem, but I prefer launching in Leonardo.. I can't come down to NJ to get some sort of certificate just to take my my little boat out once or twice a year.. To me, it doesn't make sense that I would not be welcome to spend my money on the NJ side of the bay, but its fine on the NY side...

Also, I realize we can not fillet fluke on the water, but does the same apply to unregulated species like sea robins??.. If I want to keep lets say 5 or 6 big sea robins, do they have to stay intact, or can I keep 1 carcass just to show what they are???.. I know these are dumb questions, but I also know that on any given day, hundreds of boats in NJ are boarded, and I just don't need any hassles about keep a sea robin whole or producing a certificate that was never asked for while renting a motorized vessel in NJ.. any pertinent info would be appreciated... bob
