[Rhodes22-list] Measured Hull Speed

[Roger Pihlaja]

The hull speed is measured by an Autohelm ST-50 knotlog.  The 5-1/4 knot
cruising speed is achieved at about 60 -70% throttle.

> Hi Everybody,

> The recent discussion re 4-cycle vs. 2-cycle outboards got me wondering
what kind of fuel mileage the new engines, that some you rave about, are
achieving in actual service on your Rhodes 22's.

> Fortunately, I've lived on the same Sanford Lake since 1976.   Over the
years, I've been able to do multiple fuel consumption tests in roughly the
same conditions; same 1976 R-22, dead calm, little or no current, & with
just me on board motoring around at hull speed (about 5-1/4 knots).  Our
2-cycle Evinrude 6 consistantly got about 6 nm/gal.  Our current 4-cycle
Honda 8 consistantly gets about 10 nm/gal.  This difference is right in line
with Honda's fuel consumption advertising.

> So, that's my data.  How are your outboards doing relative to that
benchmark?
