Boat Launch Ramps
 

Found this after doing a search, and after paging through it, seems like some of the info is good, and a lot is outdated.
Would be nice to have something like this for the fresh water ramps too.

There is a list of launch ramps for the Delaware River here:

Also, the list of places to fish (http://www.nj.gov/dep/fgw/fishplc.htm) will show you what the horsepower restrictions are for each lake and if there's a ramp. Obviously, if there's a horsepower restriction or it's an electric-only lake, there's a launch ramp somewhere.
