| 22 x22 Austral 4B's cupped provide the push for
economical and easy low 18-21 Kt cruise in a heavy 36 Hatteras. As
always, this boat is propped for rated ++ at full working weight. |

Tony,
Finally got some numbers. Crew of 4 loaded with gear for an albacore run
into Mexico. Fuel and water tanks about one half full. One hundred lb.
ice and 300 lb. fish. Two foot swell with 10 knot cross wind. Logged 199
miles and used 194 gal fuel. Approximately 170 miles cruising at 22-2400
RPM and the remainder trolling with one engine at 11-1200 RPM.
We only took fifth place!
We did get Mexican limits though. |
 |
| Not quite 30 K's, but as the owner soon found out,
this particular hull likes the upper teens to lower 20's anyway. |

6/27/02 trip to San Clemente Isl. with
a crew of 3 had very similar numbers up to the 2400 RPM level.......above
that it picked up another 2+ knots for each 200 RPM increase and WOT reached
3200. We had significantly less weight this trip, maybe 800 lbs? Logged
175 miles and used 130 gal fuel. Tried to cruise at (or below 2200 on this
run).
Got about 88 hours on the engines as of 7/22. Hope to make a run out past
San Clemente this Saturday for more albacore. All our new stuff is running
great. My AP quit on this last trip. What AP would you recommend for my
boost?
Hope things are going well up there,
Frank |
