Hi to all. I've noticed the prices for the 74 Manhattan from 1999 to 2002 have dropped like crazy the last year and we are contemplating one as a liveaboard for my wife and I. Dockage is lined up,have a great idea of costs as have been boating for 30 years,and the price of said boat is similar to a one bedroom 600 sq. ft apartment in my area. Not concerned so much with the burn rate,as we'd only use it maybe 50-70 hours a year but we'd be going to remote areas where fuel is hard to come by and would run at lower speeds. The idea is to plunk it in a remote cove for a couple days or weeks,and use the PWC and dinghy for local exploration and fishing,then move a little bit. Or not. Enjoy life. I've run my 50' er at low speeds for years with no ill effects, by speeding up a little every now and then to build some heat. Hoping the MANS would be fine with that. Anyways I'm thinking it may use 50-60 litres or 12-15 US gallons an hour at 8 knots or 14 kmh or so,is this in about the range? So with 5000 litres in tankage I may be able to go 700-800 miles/ 1400 kms? That would be lots of extra range. Thanks much in advance for any ideas or assistance.
