That I'm going to post my fuel numbers. I must say that I'm darned tickled with them. I went by boat from Olympia to E Q Harbor Services on Cornet Bay for service on the main and kicker. EQ was the ones who installed the motors. I am 100% satisfied with the installation and the service that EQ has provided on my Honda 200 and 15HP motors. I had 280 hours on the main and probably 4 times the hours on the kicker (at the very least). Carl did a great job and I would recommend EQ to anyone. The big motor ran very sweet on the way home. Now the mileage numbers. I filled each tank with fuel at a local gas station in Chehalis. After completing my trip I filled up at the same gas pump and the boat was on the trailer both times to get the actual fuel consumed in each tank. The way up was fairly calm but I couldn't really get to the sweet spot because of all the debris in the water. My best fuel economy is between 25 and 30 mph. I traveled 115 surface miles (by GPS) to Cornet Bay using the port tank. It took 5.25 hours and 29.6 gallons of fuel. That produced 3.9 mpg at an average speed of 21.9 mph. At Cornet Bay I switched to the starboard tank. The way home was rough water with a small craft advisory. I traveled 138 miles back home and used 40.7 gallons of fuel and averaged 16.2 mph. My mileage home was 3.4 mpg. I had the trim tabs down for about 2/3 of the way. Carl also did the tune up with the starboard tank so a little fuel was consumed then. The total trip was 253 miles and 70.3 gallons used which is 3.6 mpg average. The Honda factory fuel flow/consumption gauge was very close at 71.2 gallons of fuel used. Like I've said before, my boat averages a little over 3 mpg out in the ocean but the conditions out there are a lot worse than Puget Sound so I would expect to get poor fuel economy there.

Forrest, thanks again for the test ride last year or the year before. conviced me to go with a higher h.p. on the cdory / venture hull if I ever got a 25. susan does not like the venture because of the short table but i like the head and the cockpit cabin on the same level.

Also nice to see you working with the wounded warrior program. call me if you need help wtih that. Iam a decent deck hand.
 
Camano Island was where the very roughest water was. At times I was at hull speed going over 5 foot wind chop burying the bow in the next one. I was to busy holding on to my hat to wave! Down by Langly it reduced to 3' chop. Boy was I ever glad to see 3' chop. I was wishing I was aboard one of them Tomcats. I figured it would be really bad south of Whidbey but it was 2' chop from Whidbey to Vashon Island. From Vashon to Olympia it was nice. The tide was running out so there was a 3- 4 mph difference between the water speed and GPS speed especially through the narrows (my water speed and gauge distance was greater than the GPS). I lost a little fuel mileage there too. I didn't care I was just happy to be out of the chop.

HI Forrest hope all is well Sound like pretty good mpg figures I'm getting about 4.2-4.5 mpg out of myy CC-23 with a f-115 Yamaha I run about 3800-4400 rpm 17-23mph (statute ) I will fill up my tank in a few days but the Navman 2100 says about 4mpg but I usually get a little more . This is usually in calm seas and a light non cruising configuration .We usually travel with 1/2 tanks fuel full 20 gallons water and CG stuff twin batteries and two anchors and some extra clothing but no food stuffs just some water ,soda and beer in fridge . I was out yesterday it was about 65 degrees. the water temp was 59-62 to cold to swim take care JIM
 
Nice numbers! How was the boat loaded? Any idea of the actual weight? Many of us cruise with a lot of weight aboard (not only full tanks,including water, but food, gear and clothing for a month at a time. Dinghies, extra anchors etc--which can easily bring an extra 1000 lbs in the boat.

Thanks.
 
Bob,
I've weighed the boat several times and it appears to be between 5600 and 5900 pounds fully loaded. The last time up to EQ (last posted numbers) was a solo trip. The time I got 4mpg to Everett the wife was aboard but I was able to run an average of 26mph which is in the sweet spot.

Not only do I think that the Cape Cruiser/C-Dory Venture hull is a superior design, I think having a larger motor running at 1/2 to 2/3 thirds throttle is better on fuel economy than a smaller motor running at full throttle. Just ask Ben about the improvements of hull design of the Cape Cruiser/Venture vs the C-dory. It's a natural evolution of the design. The Cape Cruiser/Venture design fixed all the complaints of the CD 22 Cruiser that the users of 22 cruisers complained about. The 25 CD Cruiser is a different style of boat although it looks the same.

I don't really have anything to base it on, but I agree with that. Plus, I think you get the added benefit of longer life out of the ponies (OB's) or any other mechanical drive unit. Another reason I am considering upgrading from twin 40's to twin EFI 50's.

Dispute, anyone, or scientific backup?

That's probably all true at a point in time . But it's also probably true that it would take about 200 years to see a financial advantage . Just my unsubstantiated opinion.
 
I agree, and there are several things (maybe even without hull design) which makes your mileage far better than what I got on my CDory 25. The 200 can get the boat well up on a plane. I was cruising a 17 knots--and that was close to the top end. At 25, the 200 hp is loafing and that hull is at its effecient speed. Second. The weight. I suspect that our 26 was at least 1000 lbs lighter, and this can make a huge difference.

Thanks for sharing the $--makes for a very effecient boat. In fact this is close or slightly better to what some have gotten in the 22 with a 2 stroke.
