Hello powercat aficionados,
Being an engineer, and prompted by a recent discussion on the PDQ Forum, I
decided to compile two years of Sno' Dog cruising data and put it into tabular
and graphical form. The data is now posted on our website at:
www.snodoglog.com/Performance.html
It shows mileage ranging from 3.8 n mi/gal (4.4 stat mi/gal) at 7 knots down
to 2.4 n mi/gal (2.8 stat mi/gal) at 14.5 knots (16.7 mph). Many other boats
can achieve similar mileage at the lower speeds, but there's no other
34-footer (that I know of) that can touch our high end numbers. (Even the little
Camano 31' burns 9 gal/hr at 15 kts for a mileage well below 2).
I also posted some comments about running on one engine to save fuel. It
appears that, if you go slow enough, it might actually be possible - even on a
boat like ours without featherable props. But you'd have to cruise below 6.5
kts. In exchange, you might get something over 5 miles per gallon.
Happy - and economical - summer cruising,
Henry
