One US gallon is actually 3.78 liters and a gallon of water weighs about 8.3 pounds, but I believe a gallon of air will float a lot more than 8.3 pounds. The deeper it goes into the water the more lifting force it should have due to the increased pressure at that depth. It would be interesting to find out what the formula is. I know a gallon jug is enough to keep a person afloat in the water, but I don't know what a person in water actually weighs compared to on land. I put some foam in my mainsail at the top and I checked it with actual weights in a bathtub before I installed it and it floated over 17 lbs of weights.Originally posted by Art Porter
One gallon is equal to 4.4 litters.
A gallon of water weighs about 8 pounds.
This is the maximum floatation available from a gallon jug.
In the November 2002 Mainsheet Ed Jones printed an article about Turtling. The Hobie float #30115 produces 24 pounds of floatation and costs about $90.00 in 2002.
I didn't make my adapter to be quickly removed but I'm sure that could be done. Mine only requires two screws.
It is the gusts that dump us in Kansas. A nice breeze can have a monster gust every so often. I tend to get too relaxed and don't at times respond quick enough.
The float is just some insurnace that I will have a good day on the lake even if I do dump a time or two.
I'm sure I pay a speed penalty by having the float aloft but to me it is worth it.
A day on the water is still the best medicine I know of.

Prior to resealing the mast with expandable foam, as I think it may be time to do so with my '89 Model 2, would it be of any benefit to bouyancy beyond the trapped air to insert a couple of those foam swim noodles into the mast?
