We brought our speed boat and were given a slip in the Breezy Point Lagoon, right outside the door of our condo. Launching the boat was really easy and they had dock boys there to help you. Trailers are parked right at the launch, which can be crowded, but the dock boys assist you and make it trivial. The slips are nice and they come with a few ropes to help moor the boat. We had our infant and felt at ease having him crawl on the dock system.
The lake is a nice size and it's fun to cruise slowly or to open it up for a while. I would highly suggest a lake map with a depth chart, however, as there are rocky sandbars in more than a few locations throughout the lake. The best part of the lake tour is to go up the river on the southwest corner of the lake.
