MPerry:

Yes you can launch a big boat and use the trolling motor only. But you will get into trouble if you fire up the gas engine to get the boat back on the trailer at the ramp.

The officials at hovey are really concerned about protecting the ramp. When one uses the big motor to get the boat back on the trailer it washes away the soil and rocks at the end of the ramp.

So get a very long rope and hope that there is not much wind. I also don't remember seeing any courtesy docks either. So if you pull the boat up on the shore or the concrete ramp hope you have some type of keel guard material on the bottom of your boat.
