The mileage at displacement speeds-- is very similar between the 25 and 22. We ran at displacement speeds most of our last several weeks on the Tennessee River and were comparing with several 22's. Look at it this way, if you are getting 5 to 6 miles per gallon at 6 mph, the 22 will have about 46 gallons of fuel usable, and the 25 will have about 95 gallons of fuel usable. Let's be conservative and say 5 miles per gallon for the 22 this will be about 230 miles, and for the 25 will be 480 miles. (This is without any 10% safety margin). I was discussing with Jonathon Arthur on "Salty" about his taking his 22 to the Virgin Islands. If you look thru the archives, you can find folks claiming up to 16 mpg at very slow idle speeds with the 22...
A problem is that many C Dory owners want to run at 8 knots (9.2 mph), not 4 to 6 mph, and thus get far worse mileage than can be obtained at lower speeds.
Launching--a lot depends on how the trailer is set up. With the Load Rite trailers, which have target bunks, and I put slicks on these, we just drive on, the trailer, Marie hooks the strap on, and tightens it up--usually less than 3" from the bumper on the winch post. I keep the boat centered on the trailer, and Marie drives the truck out. It is more difficult to climb out of the 25, but we have a collapsable ladder. I then drive down the parking lot, bump the brakes, and the boat slides forward to the stop. We tighten the winch strap, put in the chain to the bow eye, put the two straps from the trailer to the transom and the one strap over the cockpit. We often load faster and easier than most 22's. I don't see a lot of difference. I have single handed the 25 launching with a 30' long RV. (In that case there were docks along side where I could board the boat.)
Gen set while running:--it is mounted on a bracket made of Starboard, (bolted on) which is on the port side of the splash well. I posted a photo of the bracket in the past, and will be doing a series of photos on the "improvements" (past and present) on Thataway. However, we rarely need to run the genes while running--even on 90*+ days--the breeze on the water is enough to keep us cool, with all windows open.

. Maybe I can do some sort of laborious bucket by bucket tank refill as a test.
