Hi all. A question which has no doubt arisen a few times and of which there are numerous variables and answers but I shall seek opinions anyway. I currently own and liveaboard my C Kip 40 with twin ford Lehman 120hp engines but after a cramped few days with guests I've decided that when I retire in 6 years time I definitely need a bigger boat! Looking to upgrade to something like a Hershine 529, Tiger Marine 55, Hatteras 53 or 58 yachtfish or indeed any similar vessel that may catch my eye. I generally cruise at around 7 knots in the c kip burning somewhere around 20 litres ( 6 us gallons ) per hour. All the abovel boats have quite a few more horses and are capable of travelling quite a bit faster but my question is if I keep the speed down to similar 7-8 knots, obviously I'll use more fuel, but how much more do you think? When I retire I'm off to cruise the Mediterranean and, whilst I'm in no hurry and can sit and wait for the next pension cheque to buy some more fuel, I don't really want to burn huge amounts more for a similar speed. I know that if I am throttle happy then it'll cost but speed for speed will a 55 burn much more than a 40? Let the debate begin! Thanks Iain.
