http://www.wally.com/wally-118/ Very unusual cruiser stopped at our local fuel dock. At mega amounts of fuel burned to go fast, maybe it does not pass too many fuel docks!
If I read those specs correctly it can go 300 nautical miles on a 22000 liter tank of fuel at a rate of 4500 liters/hour. Or does range refer to round trip? Then it would be half that. Either way you will need a very high limit on your Amex card.
trolling ? I wonder if that is one of the hull designs that when at speed it is cruising on foils like the new Navy Fast Frigates being partly built Manitowoc WI. The basic shape is a similar design to avoid radar and such.
