There is a specific formula one of the engineers here will use for you, it will give you your answer, But...

We need more info. What is the boat, how heavy, are you dragging nets, RPM range? Is the engine in tune? Is it your main or running a genny? Any power consuming accessories on it (hydraulic, alternator, inverter, pumps?)

Hi Bruceboating,

Best guess on fuel consumption (at hull speed, which is probably around 6 knots) is ~0.5 gph.

Regards,

Pete

Bruce,
It depends on how fast you run your Albin.

I cruised mine at 8.5 knots and a bit over 1hph at 2750rpm. And later on (most of my time w the A25) I ran at 7.35 knots. Just got tired of the running 8 knots.
I should add that I had the older style hull that was more easily driven. The later hulls (wider astern) are slower w low power but faster w 65hp or so. It all has to do w the hull shape below the WL. My old hulled Albin would go 11 knots at WOT but I couldn’t basically see where I was going the bow was so high. Took 34.5hp to to this too.

I think there’s more of the later wide stern boats made.
Now ... what kind of hull do you have?

I have Hull #457 A 1970 I like the design and weight of these boats and the fact i can haul it around is a big plus for me looking to take its first trip on the Ohio river this summer

Im located in pickens SC I want to thank all for the info on my engine Once i get it home Clean it up ect I will have to take her to the lake And practice with her Im used to an outboard So this will be alot different especially backing up I love backing up with an outboard don't think I'm gonna like it as much with a trawler thought about adding some trolling motors for a better back up mounted to top of rudder and back a bit Just a thought Dont bite my head off on that one to hard Im used to the outboard

Backing w the A25 isn’t bad. You can back using the rudder at 2 to 2.5 knots. 3 knots and you’ve got a handful. You need to hold on tight because if gets away from you the rudder will slam against the stops and possibly do damage.
But there is the usual prop walk. The A25 is such a light boat maneuvering in tight places w wind and current means at times you’ve gotta act fast to keep up w the A25 that loves to dance around.

Practice Practice ... and the best of luck.

It really doesn't take much fuel to push a trawler at around hull speed. Most trawlers will get between three and five mpg. These are unheard of numbers for most boaters.

I will attempt to dissuade from that idea as gently, but firmly as I possibly can.

You have a couple of options:

1) Install a bow thruster.

2) Install a stern thruster

3) Install a bow and stern thruster

4) Learn how to dock a single inboard without thrusters.

When I say 'thruster' I mean 'Side-Power' or "Vetus". NOT an electric trolling motor.

I have a 3ton 26 foot boat (see avatar) with a 20hp diesel and 3 to 1 gear that cruises at 6kts turning 2200rpm that's burning an average of .35gph so far (180 hrs. on the new engine).

A good rule of thumb is 1 gph gives 18 hp. So at WOT you'll use about 1.3 gph.

Another good rule of thumb is that if you drop 400 rpm from WOT fuel consumption is halved so in your case 2/3 gph or so.

Fish53,
You probably only need a small fraction of 22hp to cruise at 6 knots.
We cruise Willy at 6 knots but we’ve got 8 tons and a bigger boat. Six knots being about hull speed your whaleboat must make some waves at 6 knots.
If your whaleboat was built at Uniflite I may have installed the shaft log, engine bed or rudder port.

Re the talk we burn 1gph at 6.15 knots .. 18hp applied. 2300rpm.
