It's actually the opposite in many cases.

Displacement boats often have longer range than planing power boats and certainly more cost effective in terms of fuel consumption per mile covered.

We used to have a flybridge power boat with a pair of V8 engines. It got 1.5 MPG at normal cruise speed. Plus, if you top up the tanks on many planing boats, you have a higher fuel burn as you need to lift all that extra weight out of the water (with a 220 gal tank on ours, that's around an extra ton of weight).

On our similar size catamaran with a 25hp outboard, it got 6 MPG at normal cruise speed (lower cruise speed of course). If we slowed down a bit, that could jump up to around 10MPG.

So even with tanks 1/4 the volume, you get similar range.

Particularly on larger boats, a displacement sailboat will have better range than a planing power boat as the weight of substantial fuel tanks has little effect on efficiency, so you wind up with a lot of range with minimal downsides.

Re: ICW...stop and then go situation

And with a motor boat you can have the fun of blasting past sailboats and watch them rock like crazy in your wake, and running over manatees, dolphins and turtles with ease.

Right. Displacement hull boats (i.e. trawlers) are designed for long trips at moderate speeds as opposed to gas-hogging planing hulls designed for weekends on the lake pulling skiers.

Wow. What kind of ob was it? Two-stroke motors are notorious gas hogs, so I didn't think you could get that kind of mileage. Especially pushing a larger boat.

Re: ICW...stop and then go situation

We have been Liveaboard for 1.5 years, some good areas to leave a boat on the ICW:
1. Osprey Marina, Myrtle Beach SC
2. Brunswick Landing Marina, Brunswick, GA
3. Windmill Harbor Marina, Hilton Head SC
4. St Augustine City Marina, St Augustine, FL
Hope this helps!

Re: ICW...stop and then go situation

Go to SkipperBob.net

Buy at least their publication on "Marinas of the ICW" & "Anchorages of the ICW".

You will save a ton of money if you use these publications and save a lot of aggravation. They are packed with information in a good format.

I always used them. I also had cruising guides. I liked having both. If I had to pick one or the other, I would always pick Skipper Bob's.

Same plans... headed back down south in a year+, but seriously evaluating the Chicago river route. FYI, if you're thinking about the Chicago route (calumet... Mississippi... Alabama), note that the Ill waterways will get going thru substantial maintance into summer 2020, https://farmweeknow.com/story-illino...ovember%202020.
Thanks for that consideration!! It is closed next July- November. Thankfully, next season we are doing the " North Channel/Mackinac Island and getting to Chicago" piece, so our plans ( at this point) wont be scuppered. Hopefully, by the season of 2021, it will be open again.

Displacement power boats have pretty much the same pros and cons as sailboats under power. If there is a difference, they usually have larger engines, so it's alluring to push the throttle a little further and bump up the speed by 1-2kts and pay for it with 3-4times the fuel burn and associated loss of range. Sailboats don't have the extra HP to try and fight hull speed but that's only relevant if you try to push a displacement hull past hull speed.

We switched from a 40hp 2 stroke that got 3mpg to a 25hp 4stroke Fuel Injected that got 6mpg at cruise speed. The diesel versions of the boat does even better based on reports from sister ships.

Re: ICW...stop and then go situation

I did a comparison between a 16hp diesel sailboat and a 60hp diesel displacement cruiser down the same 500 plus miles of the ICW here - https://youtu.be/s_G0wRp4WFE

Approximate daily mileage runs for both craft as follows -
Day Sailboat Motor cruiser
1............71..............50
2 ...........53..............69
3............71..............72
4............51..............74
5............37..............52
6 ...........58..............69
7 ...........46..............32
8............35..............65
9............66..............45
10.........45

The 16hp sailboat did about 3 hours to the gallon at 6 knots and the cruiser about 2 hours to the gallon at 7 knots. Not much difference in the cruising life really.

Re: ICW...stop and then go situation

We are 40 tons, 58 feet, 115 hp, 6-cyl Westerbeke, 1984. Prop is 3-blade, 24 inch Hundested variable pitch. Transmission is 2:1 reduction. Tankage is 400 gallons.

We run 900 to 1000 engine rpm and vary the prop according to conditions. On flat water, no wind we make 4 miles/gallon at around 6-7 knots. In crappy conditions 3-4 knots. Motor sailing close hauled 7-9 knots and 8 miles/gallon.

Different boats sure are different and you have to know your equipment. Our friends left Bonaire in their 50 foot trawler for NZ last season. I do t know how many stops after Panama but they were not concerned about fuel.
