Fuel Economy

I am planning my retirement within the next few years and am considering the purchase of a 40' Bertram with twin diesels. I would be cruising up and down the California, Oregon coast. My question to you is this: I am very concerned about fuel consumption such that I may not be able to afford to purchase the fuel necessary to cruise the coast. I have seen fuel readings of as much as 6 gallons per hour per engine to as little as 3 gallons per hour. Obviously there are many factors to be taken into consideration but a general estimate of what kind of fuel economy could be expected from a boat of this type would be very helpful. For example, a cruise from the Golden Gate to Los Angeles would be approximately 400 hundred miles. I am estimating that it would take nearly 40 hours to attain that goal, which is at a cruising speed of 10 miles per hour and at 3 gallons per hour per engine would consume 240 gallons of fuel at an estimated $3.00 per gallon would cost approximately $720.00 each way. These costs would break the bank and I would have to make different retirement plans. Any help or insight you could provide would be greatly appreciated. I have had several boats over the years but they have all been runabouts where fuel economy was not of major concern.<br /> <br />Thank you for any insight that you may have,<br />Jerry

Re: Fuel Economy

You are missing something Jerry. Your GPH info is very dependent on the boat, power package and speed. Using your 10 MPH number there are boats in your size range that could use 5 GPH total or way more than 10. If fuel economy is your gig, then you need to consider a single screw diesel with a seimi-displacement or full displacemnet hull. That Bertram you describe is probably capable of more than 20 knots and has a pair of 300 - 600 bhp CATs.<br /><br />Take a look at the data here: http://www.boattest.com/search-resultsTN.aspx?type_ln=Motoryacht&type2=cruiser <br /><br />You can pick different boats and speeds and get an idea of what your options are. I checked out a 37' Nordic Tug single screw that was capable of over 20 MPH, but at 10 MPH it uses arund 5 GPH. Poke around. A full displcement 40 footer, single screw , would do even better than that, but still close to your make new plans numbers . . . Good luck, sounds a lot like a dream of mine too. :)

Re: Fuel Economy

Jerry you need a passagemaker not a game boat to retire in . If you are retiring you no longer need speed because the one thing you will have plenty of is time :D . Quiet Cat has hit the nail on the head with his suggestions plus the a passagemaker has heaps more room than a game boat.There is a new breed of wide bodied cats now being manufactured which boast incredible fuel figures and can still cruise at 17 knots in offshore conditions.With the onset of the new light weight deisels and new hull designs plenty of older bigger boats (eg passagemakers)are being sold at bargin prices when the owners upgrade, you can even look at converting ex commercial vessels they are perfect for converting to a passagemaker. Good Luck ;) <br /><br />Rob

Re: Fuel Economy

I'll tell you what a friend of mine told me about fuel consumption...when it's thirsty, fill it up...and it is thirsty ALOT!!! I had a similar concern when shopping for an RV. When I asked the salesman about fuel economy, he said, "If you're worried about fuel economy, you might reconsider your purchase." Sounds like too much boat for you at this time.

Re: Fuel Economy

Delay retirement, so you can fill it. The way it is going we all will.

Re: Fuel Economy

Jerry,<br /><br />Have you considered a "Trawler". Allot slower but much more live aboard room and fuel economy is twice, or better, of that of a planing hull.<br /><br />"Trawlers" are my favorites. Their seaworthiness is impeccable and the extra room is an added bonus. And yes, you can troll for serious fish with them too!<br /><br />There are many benefits to them.

Re: Fuel Economy

Just another consideration here....What happens a few years (or maybe months?!) from now when fuel is $5 per gallon? Then $10? If you're scraping the bank already at todays fuel prices, I'd do some serious reconsidering. I'm not trying to rain on your parade here, just genuinely concerned that you can't afford this. I agree with the honesty of the RV dealer that says if you need to worry about fuel prices, this isn't the purchase for you... I think this might be a better question for a financial advisor than a boat forum.

Re: Fuel Economy

How about a "blowboat" ? the wind is free and with roller jib and other labor savors, you can sail for nearly free, otherwise, you need a medium sized trawler with a small single diesel, but you will need to learn how to back up a single engine, which has a lot of torque effect when backing, and a good deck hand to get the lines on the pilings as quickly as possible.
