cutting diesel consumption by up to 20 per cent

Notice the chart showing a decrease in fuel consumption from 1200 litres/hr to just over 400. This is a reduction of over 60%. Somebody is just making the stuff up...

“Notice the chart showing a decrease in fuel consumption from 1200 litres/hr to just over 400. This is a reduction of over 60%. Somebody is just making the stuff up...”

Or... 60% decrease in fuel consumption is under ideal conditions (open sea, wind more or less at your back) and the 20% is an overall figure. A lot of ship owners would surely appreciate even a 20% reduction in fuel consumption, if the added costs (equipment, staffing, etc) don’t eat up the savings. Doesn’t seem like a completely whackadoodle idea to me, although it may ultimately be found impractical.

I have not read the article, but I bet when the wind is good you get incredible mileage. When the wind is against you, then you only get to run the diesel. When you average the two then you get the actual cost. Were your numbers an average or just wind friendly?
