Well Crabman, out of all the "reefs" off the south shore of Long Island, Hempstead falls mostly in federal waters,and is actually (mostly) out of bounds for recreational trap fishing for NYS rec permited lobster fishers, being (mostly) outside NYS 3 mile juristiction.
I believe you are half correct, someone correct me if I'm wrong, as far as setting gear on a state reef, the rule how I read it, is no "fish" pots within 500 ft. of a state managed reef, nothing about lobster gear. I have fished both AB and Fire Island reefs over the years using lobster pots and never had an issue with compliance.
I'm just trying to let the fisher know that, if in fact they are a rec permited fisher, that the boundery for setting recreational lobster/fish traps/pots is out to 3 miles from shore, that is New York waters. That's where you can set your 5 recreational pots- in state waters - not past the 3 mile line.
Now on the other hand, if this fisher is a comm guy, word is, better mark your gear properly - or get it out of town - or a call will be made for sure.
My siggy below? LCMT area 4, - Lobster Conservarion Mangenent Team - I'm one of the team leaders that represent the areas comm lobster fishers at the lobster meetings for all of us fishing lobsters off LI in area 4, sort of gives me an interest in what's going on in my back yard, if you know what I mean.
