I too am thinking seriously about joining. I have been talking to the Punta Gorda club and they are offering the same price ($5K plus $199/mo starting in second year).
They say they currently have 21 members at Punta Gorda and 6 boats - 3 Hurricane deck boats, 2 center consoles and one pontoon boat.
I am looking for some feedback from someone that has experience with the Freedom Boat Club to see what they say.
