Purpose of day tank

I would think that if you had two tanks then it would be best to transfer all fuel to one and then only fill the other. Then sit anchored for 24 hours to allow the crud to settle. Then polish thoroughly and finish the first one off as well.

" I consider fuel polishing and day tanks unnecessary."

So do I! With regard to saddle tanks causing a listing problem, The use of Duel Racors and an accurate fuel gage make managing both problems quite simple!

"It is 2 gal, it is above the stove burner, so feeds the stove by gravity. Its capacity is enough to keep the stove alight for 48 hrs"


That is really efficient , our Dickinson unit takes 2-4 gal per day , the 4 gal is needed when below 0F, About 20,000BTU output.

We are in a temperate area, no extremes of low or high temperatures, so typical stove usage is to warm up the cold boat while running, then turn it down to maintain a comfortable temp. That is where the 2 gal day tank shines.

I rather think not. To provide trim the the tank would have to be installed to one side which would create a list. Or, one would need two days tanks mounted outboard on each side. Centerline, it provides no trim opportunity.

Well, I should have made clear a given station for the supply tanks for this to make sense. My apologies.

It made sense in my mind, as I was picturing four supply tanks at outboard stations. With the ability to transfer fuel from any supply tank - to the center stationed day tank, this would be a ballast trim option. It would be nice for fishing load and or provision usage (long term)
