Bobbi - Insulation is used instead of barrels. Use 3-4 layers (ea 2" thick) of insulation stacked inside a frame - top. Insulation as bouyancy will cause the "float" or raft to float closer to the water than barrels which makes climbing out of water onto it easier. Insulation block will be more stable than barrels. Raft can be made 4x8 or 8x8 ft (larger tends to be more stable). I would use at least 3 layers of 2" for a total of 6" thick. If floation is still not enough add another 2". Amount of insulation needed will depend on how heavy of wood is used to build the raft frame.
