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
