To carry on from a digression on another topic on WOT fule consumption....<br /><br />Many fishing boats have large tanks to get you out to sea and back. For example I have a 109 gal tank on a 24' boat = 150 gal is not unusual on some brands. If I remember gas weighs around 6+ lbs/gal. SO I am carrying 650+ lbs of load when tanks are full. That's as much as 3-4 people.<br /><br />In aviation (and also recommended by a lot of car manufacturers), keeping your tanks full is goodness as there is less room for condensation to form. This goodness, if true, can be an expernsive proposition with a big tank (in my case I'm adding 20% or more to the weight of the boat).<br /><br />What kind of an issue if this really? For one thing the condensation would likely be fresh water which is minimally harmful for most aluminum tanks (and not at all if you have platic yanks). And most decent setups have a fuel-water separator. And I always learned in my auto mechanic days (no separators!) that a little water in the gas isn't going to kill anything.<br /><br />Based on all this, does one keep your tanks full or not? (Assuming you are not heading out far enough where you actually need that whole tank at once).
