My experience with beach access is that we have lots of access in the Northeast. Ramps are plentiful and mostly free,

Places like Sail Newport for mast up storage. At $300 a season for an 18ft cat its a bargain.

On Cape Cod they recently outlawed jet ski's at all of the national seashore waters, so now we have zero competition at all the ramps the jet skiers used to use.
