topping off fuel tanks?

Interesting arguments for and against cruising with full fuel. I too cruise with just the fuel I need with reserve, I do not keep the tanks full. In a Tomcat, this may be a bigger deal than with the other models. Full fuel adds 900lbs to the boat and it is a waste to push this weight around if you're going 50 miles.
In terms of fuel, I sure wish there was a way to use a stick instead of a gauge. My gauges only show about a 30 G delta from "E" to "F" (each tank carries 75 G).

The J.C.Lately is a late '06 CD-22 with (purportedly) 25 gal PE tanks. Does anyone have any recommendations regarding how much of that is actually convertible to "go"? I can't believe a system using pickup tubes actually gets all the juice out of the tanks.

Paul-
I can't answer the capacity question, someone who ihas run one down and then refilled it would have to answer. However, on the older 18 gallon Mollner tanks on the earlier CD-22s. the tube length varied a lot from boat to boat, with some folks getting 17.3 gallons and others more like 15. Just depended on who cut and made the pick up tubes up, apparently.
Also, you wouldn't want to go right to the bottom of the tank where all the water and crud accumulates, anyway.
I siphon out the bottom of my tanks every year to clear out as much accumulation as I can get out of them.

Joe,
Another school of thought-if your pick-up tubes are right on the bottom you will be sucking up and filtering any crud as it accumulates and before it can build up to create a problem? My old tanks (2002) had a curved plastic tube for a pick-up, which put the screened end right along the inboard bottom edge of the tank. Although I never ran them anywhere near dry, logic would indicate that almost every bit of fuel could be used. I never had a fuel related problem with the system until one of the tanks cracked.

I just bought an 07 CD22 with the 25 gal tanks. I spent the week-end doing the break-in. I ran the port tank until the engine stopped. As best as I can tell there is still about one gal still in the tank. I think it would still pick up some if I ran as idle speed.

Rick,
I just replaced my tanks because one of them cracked. New tanks are 23 gal and are about 2 in lower in height because they are designed to fit on the new molded floor which is higher. They are also about 2-3 in wider, so the center gap under the splashwell will be about 6 in narrower. I elevated my tanks about an inch on wooden strips thinking the old fill and vent hoses would reach ok-but the location was off just enough that I had to replace both fill and vent hoses. I know the factory advertises 25 gal tanks but here is the molded tank label on my tanks:

I top off my tanks after each trip, usually 25 to 40 gallons depending on the trip. For extended trips I take along 2 extra 5 gal jugs. I pulled my boat up from Seattle with ¾ full tanks; I see no problem keeping them full. The way prices keep going up it makes sense to top them off each time.
With out fail I usually fill until the breather sprays a little out, then slowly add tell the tank is visibly full.
I hate having to stop for gas when we are heading out, seems to hurt less when I fill her up after a trip.
About $40 diesel round trip to launch
$20 for the tunnel pass
$30 to $40 for parking
Paid $120 seasonal launch fee so hopefully 10 trips will = $12 a launch
Average about $125 in gas each trip
So I guess it casts us around $250 to $300 each time we go out, and it’s worth every penny.

Haven't found the big flat fish but these taste great!
And it isn't all about fishing...
