[QUOTE="richg99, post: 251242, member: 4376"] PSG-1 Interesting question..."will having two fuel tanks in place of foam provide flotation".... My un-educated guess is...if the tanks were [i]empty[/i] and sealed, they would be similar to foam in displacement, other than the slight additional weight of the metal tanks vs foam. However, if they were [u]full[/u] of gasoline, then they wouldn't provide much, if any, flotation since gasoline weighs almost as much as water 6.+ vs 8.+ lbs per gallon. Any empty space on top of the tank that contained air and help somewhat. The tiny outside vent of the tank would gradually let a small amount of water in. But that might take a week or more. regards, Rich [/QUOTE]
