MAtt you make me laugh

Seriously though, the reason I started this thread is becuase of this observation:

YAMAHA 225 4-Storkes
RIB MAR.CO 25 CABINATO

4680 LTRS / 2696 Miles = 1.735 LTRS/MILE
according to the chap who saild the boat Giovanni Bracco.

My 200VMax 2-strokes (not the HPDI) with 17" pitch Yamaha Salt Water prop (changed the 21" Yamaha Pro prop I had on it for this one and I may go up to 19") on the same boat gives on the FLOSCAN and between 3500-4000 revs about 1.3-1.6 ltrs/mile in moderate seas, trim -3 and jack plate up 2 notches. I think the speed is between 24-26 knots and the boat is a little heavier (I estimate between 200-300kgs, due to added bulk heads in the cabin, a cooker and a frige, and some added decoration for comfort etc) than when it did that raid when everything was bare for obvious reasons.

The logical thing would have been for the boat to go slower and have higher consumption but it does not.

I thought is very starnge and either the guy who sailed the boat is wrong or I have a great little 2-strokes motor
