Maybe the Marina is not owned by the restaurant and wants to re-coup some of its operational costs to let you dock there?
I had a great day Saturday exploring potential hangouts.....gave my buddy the choice of hit Newburgh or LaMarina and we would stop on way back.
He chose LaMarina...had lunch there...interesting spot, worth the visit.
Stopped in Yonkers, tied up under the "transient dockage" sign. The gate was locked!! that stunk!
Next stop Dobbs Ferry, went to half moon and the train station now has a restaurant, very nice, "Hudson Social".
Dobbs has nice transient docks enough for about six boats depending on size, the water was deep...worth going back.
Tarrytown (WI) next then Haverstraw,,,the resort.
We had a blast!!! Definitely check out Dobbs Ferry.
