Fuel Capacity

I was browsing through the Fuel Check section and I saw refferences to 200 gallosn, five hundred gallons, etc.

My boat holds ninety gallons of diesel. OK, it's small for a trawler, either 28 or 31 feet, depending on who you ask.* Is this an unusually small capacity for a small trawler or did these folks have much larger boats?* How much fuel does your boat hold and what is the length?

RE: Fuel Capacity

My 40 Albin, single engine holds 360 and that is too much IMO. 200/250 *would be plenty.

My ex, a 34 single screw Mainship I *held 220 and I thought that was too much. 150 would have sufficed.

RE: Fuel Capacity

My 34' MT holds, as best I can tell, 200 gallons, spread over 4 plastic tanks.* It was advertised as 300 gallons, but I don't think so.* 200 is overkill for how I currently use the boat; about 100 gallons/year.

RE: Fuel Capacity

400 gallons on a 37 footer. This is enough to reach Ketchikan from Seattle with lots of side trips in the Boughton's. I was pretty low when I filled up in Ketchikan and don't think I would do that again. Running out of fuel in the Dixon would not be pretty.

RE: Fuel Capacity

My Monk 36 carries 300 Gal. of fuel, the holding tank 45 usually we fill up when the holding tank needs a pumpout. I don't have a floscan but calculate we get about 3 statute miles per gallon @ 8 - 8.5 statute miles per hour.

When I owned a Camano, Spirit #170, couple of times I carried 2 - 5 gal jerrycans of diesel in the cockpit but never really needed them.

RE: Fuel Capacity

Ron,

My boat is closer to yours in some ways (especially size). We go much slower w much smaller engine. But we burn 1gph and if you go fairly slow I'll bet you burn very close to 2gph so we probably cycle fuel at nearly the same rate. We burn half as much fuel and have half as much capacity. Fuel capacity on a boat is highly related to the boat weight and fuel as ballast factor however planing boats probably carry more as a percentage of disp due to their excess consumption. But full disp boats are frequently designed for much longer range so would need more for that. But fuel on a boat is dead weight and I would not want anymore than necessary. At 100 gallons we have probably twice as much as we need. I'd rather have smaller tanks and cycle the fuel faster. Fuel is available almost everywhere even in SE Alaska. When I had new aluminum tanks built I asked for 2* 35 gallon tanks but got ignored so I still have 2 50 gal tanks. How often do you run low on fuel? If never you've got too much tankage but to change that would be expensive unless you had to change tanks for some other reason and the boat may suffer resale value as well. After all that I'd say 90 gal on your boat is very normal or just about right.

RE: Fuel Capacity

Tadhana holds 400, but I only filled full one time. The entire boot top in the stern was underwater, It was an uphill climb to the pilothouse. at 2.5 GPH I find half a load, 200 gallons is more than enough. Some people worry about condensation in a partially filled tank. I have fiberglass tanks so am not too worried about condensation. Many years experience tells me that fiberglass tanks condense far less water. In 700 engine hours in 2.5 years have not seen one drop of water in the filter. Holding tank 45. and water is 300 which lasts about 8 days of normal use, and 16 if we are careful and do not use the washing machine.

34 Californian LRC with two 125 gal aluminum tanks for 250 US Gal total. This equates to approximately 60 hrs of cruising with 15% reserve.

RE: Fuel Capacity

Our 32 footer holds 100 imperial gallons/454 litres, and burns 10 litres/hr at 7.5 knots. So theoretically we have a range of 340 nautical miles, although I like to start looking for fuel after 20 hours or so.

This summer there was a large (80'?) yacht at the fuel dock, and after fueling to the tune of $8000 his credit card was declined. Never heard how that turned out.
