I opened up my front inspection hatch, saw none, and thought "gee, the last jerk must have thought he could save a few ounces by taking them out..." and bought replacements and put them in. Some time later I opened up the stern and found all the cubitainers that the boat is supposed to have, back in the stern behind the cockpit.
Not unless your boat has a major hole in it and is full of water. Then it would float 'less low' than with standard flotation bags.Wavedancer said:Here is one for the physicists: Will having more cubitainers make your boat float higher in the water?

The Party baloon empty weighs a lot less than the plastic water jugs the builders stuff in Lasers.
There is a pretty good chance a helium filled water jug weighs as much as the surrounding air
