The holes are there to let water in and out as conditions change. This stabilizes the tube with the outside water level. For example, if it were sealed and too much water splashed in compared to the outside level, the pointed end would be too heavy and cause stability problems and the opposite for not having any water behind the seat.
At 180# plus 25# cargo, I sit 3" above the water in my ODC light, which has extra buoyancy due to the inflatable seat. But the NFO's would be better for someone over 220#, but be prepared for sticker shock.
