Is the short of it that nothing in their class, meaning C-Dory, gets even remotely as good mpg @ speed?

I've looked at Rangers, Rosborough, etc.. It looks as if everything is a gas guzzler compared to C-Dory.

Good point. I have heard of concern from C-Dory owners that with the increase of fuel prices, maybe they should sell their vessel. If you love boating, I would think that today's prices would want to make you keep your C-Dory all the more. Perhaps you will have to cut down in some areas of spending to budget for buying fuel but that would be a good sacrifice to continue on the water doing what you enjoy.

Yes, when I run close to a couple hundred kms fishing in a weekend I feel like complaining then I go for a ride in my buddies Boston whaler conquest and I shut up. I think there are comparable boats out there but it is so tough to replicate and compare the benneto ANTARES 8 and others might be close in speed and mpg. The nice thing is if we slow down and smell the roses oilur mpg goes up. Sometimes it pays to have autopilot

Absolutely. Love my AP, and smelling the roses.

We did most of our cruising this summer at hull speed and at most 25% of the time we pushed the throttle to get up to plane speed when we wanted to make time in some of the longer fjords on Vancouver island. Almost a month of cruising on about 340 litres fuel, That's less than 100 gallons for the American's. When we were cruising in Nootka Sound we were watching sport fishermen in their Bayliner's and Kingfishers constantly passing us at high speed with 250 HP motors to try this or that fishing hole. I don't know what is more important, high speed boating or fishing, but they were doing both. I am sure that many of these boats would use more fuel in a weekend than we would in a week or two. The fuel for my boat was one of the cheapest parts of my trip to Vancouver Island this year. The great thing about a C-Dory is that it can take you to a lot of great places on the water with very little fuel. I don't plan to sell mine anytime soon and an upgrade my be farther away than I thought it would be.

That is a gorgeous little boat. That cockpit is amazing, and the smartness of the space allocation...

I'd like to know more about these.

For sure, the C-Dorys are very fuel efficient compared to most other on plain capable boats, however that doesnít mean that cost for a cruise such as we make to SE Alaska isnít noticeably more, when fuel prices go up, as much as they have, since our last cruise there in 2018. Fuel cost including that for towing to launch at destination & cruise has always been by far, the most expensive item for all our cruises other then boat related parts having to be replaced. On a average trip to & cruise in SE Alaska between the boat & tow truck we will use 750 gal of combined diesel & gas, so the difference between fuel prices changing up or down of $1 per gal can mean a difference of $1500 for the trip with our overall average cost of 8 SE Alaska cruises per trip being $3000 for fuel. The total other cost of these trips, which were between 6 weeks & a three month time period, were not more than about $600 not including food, which is about the same whether at home or on a trip as food staples are Cosco & we seldom eat out. The Marinas are very inexpensive compared to most anywhere else & the majority of nights are spent at anchorage or free docks. Not a single night in a motel & the road trip night spots free with exception of a very few stays in Canada Provincial Parks. Overall prices would have have to go up much higher than now to not get ones moneys worth as any one of all of our extended SE Alaska cruises would be considered a trip of a lifetime for many boaters. Making fuel prices much easier to handle for us is having the boat, tow truck & all other items used for the trips payed off long ago & new items payed for at time of purchase.

As Daybreak suggest, if we would have been on any comparable boat to our CD22 with a deep V, the fuel cost would have been much more to start & the increase much more over the time period we have cruised our boat. Our original choice of the CD22 for the boating we love to do has been one of our best lifeís choices.

My opinion on boating has never changed.

If you love boating but do not like today's gas prices, get a sail boat. If you want to go faster with less manual work to do on deck, get a power boat. If gas prices are a concern, get rid of power boat. Take up sailing or quit boating.
For most of us C-Brats, owning a boat is a luxury. If a person can not afford a luxury of any description, then you know what the alternatives are.

Personally I like Harvey's approach. Boat at hull displacement speed, 5 or 6 knots. Only gun the engine(s) to get out of a sticky situation like medical emergency or impending bad weather.

Martin.

For my tastes, the Antares 8, while kind of cool looking boat, isn't that much like a C-Dory. The Antares website doesn't appear to give me the information I'm most interested in (for instance particulars on draft, deadrise and hull shape), but what I can see or infer makes me think it's not my kind of boat. (Other websites sites indicate 20 degree deadrise at the stern and draft of 2 1/2 ft.) For starters: 250 Hp to go 40 MPH vs. 90 Hp to go 30 MPH tells you something about likely fuel efficiency at, say, 20 MPH - or at 5 MPH, for that matter. It all depends on what you're looking for, but I also think I know which boat I'd rather be on for an extended cruise, based on cabin layout and amenities.

Concepts of boating and fuel economy do not easily comingle.

Ah-ha. What about sailbotes since the wind is free?

Yes, wind is free. Sails are not.

Aye.

Hereís the answer I think you're looking for.
My 2008 23 Venture with a Suzuki DF 150 burns 5 ga per hour at 20-22 mph.
This is at cruising weights, full water and a fair amount of stuff. Thatís 4mpg or slightly better at about 300% faster than most displacement trawlers.
Iíve owned a lot of boats, but none that cruise as efficiently and carry all my gear like the C Dory.

I have found this site is pretty accurate for my Suzuki 90 and bet it will be for the other outboards as well.

thanks for the answer. I'm not at the point where I can deduce that kind of information at a glance.

It's as if there's no contest in the 22'-26' range.
