Make it so Player Can't Push Boat (Buoyancy and Water 5.2 plugin)

So I am using buoyancy with the water plugin shipped with 5.2. Am I missing a setting? When I start the game my boat drops down with the player on top of the boat. The player is however able to walk into the walls of the boat and the boat will start to tilt in that direction. I’ve tried a few things, I’ve set the mass of the character to .1, I have all four pontoons setup with a radius of 500 for each 4 pontoons. I am trying to get it to where I can safely move around on the boat (including the edges) without pushing or tilting the boat.

Any suggestions?
