Re: Operationg Costs of ~50' Trawler or Trawler-Like Boat

NC is over a dollar cheaper at marinas this week compared to southern marinas on way to west palm beach last week

Wow! That's over 7,000 lbs of fuel.....

I haven't found that much difference in operating costs of sail vs power, other than those associated with a longer boat (marina costs and insurance). The maintenance state of the vessel when you buy it will be a factor. Trawlers have more systems, requiring more maintenance and more things to break down. The difference between the durability and cost of ownership of high quality and ho hum quality is pretty big.

Fuel is not the biggest cost of operating a trawler, although it is a clear eyed moment when we have to refuel and bring on 2,400 gallons. The gph you burn will be a function of cruising speed and hull form. Delfin burns 2.7 gph at a little over 7 knots, giving her a 6500 mile range. Increase the speed to 8.25 knots and the burn is 4 gph. At 9 knots, 8 gph. The reason she is fuel efficient has nothing to do with modern design, since she was built in 1965 from a hull first built in the 1860s. She's efficient because the hull was originally powered by sails for service in the herring fishery. An easy test to identify a fuel efficient hull is to run the boat at about 60% hull speed and look at the wake. If there is one, the hull is going to be a diesel sucker. At 6 knots, Delfin leaves less wake than a row boat. At 9.5 knots, you can surf the wake and the fuel consumption shows it.

Re: Operationg Costs of ~50' Trawler or Trawler-Like Boat

Hi, operating costs of any boat will be higher than you might imagine, and very dependent on how you use her. We own a Seahorse Marine 52, twin-engined trawler in which we have traveled 13,000 miles from San Francisco to Grenada. Fuel is not been our main expense. At 7 knots we get 2-3 nm per gallon depending on sea conditions. We have 800 gallons of fuel.

Most systems need care and maintenance. For example changing engine oil (8 gall) every 250 miles adds up in cost. If you will be at anchor a lot, you will need to run the generator (fuel cost particularly with A/C) and will go through batteries (we have 12 at $350 a pop) more rapidly than if you are on shore power most of the time.

There are so many things that need maintained/replaced it is difficult to enumerate them all. Conservatively $20,000 a year is a reasonable minimum and it could easily go higher. If you are willing to do a lot of basic servicing/cleaning yourself then you will avoid the high labor costs associated with such work.

Please don't be put off by the costs, passage making on a trawler is a wonderful way to live.

Good luck,

James and Charlotte on "Pegasus"

Lived like kings and thats averaged out over 2 month trips but still cruising about 1600 miles/ year.
We have just bought another trawler and did a lot of research on fuel, this boat is bigger not by choice it was just a good deal. 57' x 18'8" beam draws 6' 215 hp cat diesel full electric galley, hurricane heat, generators when we need them. Weighs 46 tons canoe stern, aluminum construction. It burns 4.5 USgals/hr plus heat and generator about another 5 gals/day. This is a big boat our last one had a 2 cycle detroit diesel at 9 kts burned 9 CDn gal/hr at 8 it burned 3.5 at 1400 rpm. Get a 4 cycle engine, lot quieter and easier on fuel.
I would only buy a boat with 1 main engine twins will cost you twice as much for maintenence, etc. less room. There are some good deals out there.

Our cruising has so far been done all on the west coast of British Columbia. It took me 1 week to sell our last boat and 4 years to find this one. It helped a lot that are dollar is at par with the U.S. dollar as well plus the economy has made used boats more realistic. When we cruise we always anchor out. Its a lot more relaxing.

Hope this helps
Ditto! Almost exactly the same optg costs and maintenance costs.
In our DeFever 54 we had twin CAT 330's and ran 4 gph at 1600 rpm around 7.6 knots from Cape Flattery to SD#1 off San Diego. Carried 1800 gals of fuel and had over 1/2 tankage left on our trip down. Cheers, Phil

Do your really change the oil every 250 miles?? At 7 knots, that's less than 40 hours on the engines.

Oops, my mistake, I meant every 250 hrs, not 250 miles. Thanks for catching this.

Re: Operationg Costs of ~50' Trawler or Trawler-Like Boat

I have an 83', 80 ton boat that gets between 1 to 2 mpg, but I usually choose 1. On another boat with twins I got 4 mpg @ 7k. Much of your costs are determined on how far you go, how fast, and where you stay. I haven't stayed at a marina in the last 5 years. I carry a shore boat for supplies or do those things at the fuel dock. It's beyond nice having a mote around your castle.
Bigger boats often have medium or heavy duty diesels as opposed to the light duty in most yachts. They last longer and have fewer failures but cost more to fix. My mains haven't needed any repairs in the last 2500 hours. Everything is heavy duty and field repairable. Even sw impellers are still good. Look for non turbo engines if you want to save fuel and trouble.
If you have a plastic boat with little wood, then you care for it like a corvette. If you can maintain your boat and do routine maintenance on the engines your expenses won't be great. No sails or rigging to renew.
