Just returned from by run from Fort Lauderdale to Rhode Island. 1700 Miles to figure out fuel burn with twin SP225 Lehman Diesels.
I found that at on average I burned 6.5 gallons per hour at 1600 RPM with a average speed of 8.6 knots. At 1400, I would be close to the 4.5 to 5 per hour and at 1800-1850, 8 to 8.5 gallons per hour . Add wind and current and these numbers get better or worse as expected.
Given that five people plus gear plus a heavy dingy were aboard, I was pleased with these numbers.
If interested, I created a website for the trip:
www.redgypsy.net
Besides pictures and blogs, I will also be posting reference materials on the major systems as I have time or find them so that the Cheer Men community can begin to build a reference Library. If these type of site exists or you have material that can be posted, let me know.
Regards,
Coast Guard Dave
