At 1,800 rpm we made between 8 knots and 2.8 knots.
Hopefully, that was 8.2 kts, not 2.8 ? :)
No I mean 2.8 knots.
People who assume that they can always
throttle back to extend their range,
need to realize that is not always true!
I did about 4000 nms (total) last year on four
different Nordhavn 47's, northbound on the Pacific
Coast. Most trips were non-stop from Dana Point to
Seattle, and some junky weather was experienced
causing occasional throttling-down to 3-1/2 or 4
knots. Typical weather conditions allowed 7.5 - 8.0
knots, but overall average was right around 7 knots.
I also delivered a Nordhavn 57 from Dana Point to Ft
Lauderdale last year. We made only two stops of about
36 hours each (Acapulco and Balboa, Panama), and spent
5 days beating into persistant 25-30 knot
headwinds/seas in the Caribbean. But when it was all
done, we averaged 8.8 knots @6.1 gph for the 4500
miles in 25 days, just under 1.5 nm/gal
Having been aboard Paul's boat (but not underway), I'd
reckon he's spot-on with his 9 knot@10GPH figure, may
even have some breathing room in there. Sometimes
he'll be down to 4 knots, but overall, if anyone wants
to start an "office betting pool" on his trip to
Hawaii, I'll put my money on 8.75kts @ 9.25 gph for
the leg.
