RE: real world fuel usage 120

Andy, I think weather conditions probably came into play there, but it is interesting that overall the time was so little different as a percentage, (about 7%). Motion30 you have a sister-ship to mine, only it is even older, mine being a 1975 hull. I find the sweet revs/speed about 1700rpm by feel and sound and bow-wave, but the significant saving is the extra cutting back to the 1500rpm region by the looks. I don't have a fuel flow meter, but I assume yours is the std Lehman 120, so the reading should translate to mine.
