Not bad.

BTW: Another great day on the water. ;-)


Did the first, real "mini-cruise" on the GB today. Left the marina on Cape
Cod (near Wood's Hole) , through the Cape Cod Canal, then northward to
Scituate, MA.

Set the throttle to 1700 RPM as we entered Buzzard's Bay and didn't change
it until we arrived in Scituate, 7.5 hours later. Total fuel burn:
Approximately 16 gallons, not counting whatever the genny used.

With 400 gallons of fuel at the start, I am starting to think we have a
lifetime supply.

Interesting little trip and my first on this type of boat. We hit the canal
at the worst possible time ... max current against us ... and barely managed
to maintain 3 knots headway. There were people walking the hiking trail on
bank of the canal that waved as they passed us by. The only person we
gained on was an elderly man walking along with the aid of a walker.

It was actually very enjoyable and relaxing, even though it was a bit snotty
as we exited the canal and into Cape Cod Bay. A NE wind had fetched up the
Bay a bit, but it flattened as we slowly progressed northward to Scituate.
It really didn't seem like all that time had gone by.

I need more practice backing a single inboard into the slip in Scituate
though. It's a bit tight and I am too used to twins swinging big props that
move the boat around. The GP is totally different. Turns on a dime going
forward (big rudder) but nada backing up. I'll get the hang of it
eventually.

I have a friend who has an older GB single. Will never get whip lash going
out the Gate to fish salmon. But does do well on fuel.

So do we all need practice, regardless of the number of years with a
single screw.

General tip, try to achieve balance between sternway pressure on the
rudder and prop walk. With the rudder set to oppose the prop walk, you
should be able to roughly "steer" in reverse by increasing rpm (and
prop walk) when the rudder begins taking you off in one direction and
decreasing rpm (or coasting astern in neutral) when the prop walk gets
too dominant. Once you get a couple knots sternway up the prop walk is
less of an issue.......but you may not want to get up to that kind of
speed backing into a slip.

You can always "cheat" and use a bow thruster. :-)

Speaking to Chuck's point, although it probably will not work as well
on a powerboat, one of my old sailboat maneuvering tricks was to give
the boat a good shot of reverse while still in the clear, build some
momentum, and then back in at idle speed or totally in neutral. This
requires some practice to learn how far you can glide before losing
steerage. On a sailboat it is quite a long way. The main thing with
reverse is to be quick and decisive with the application of power,
building enough speed that the rudder can get a bite.

The other big trick to master is the "back and fill" maneuver where
reverse is used only to check forward speed, and forward power is
applied in short bursts with the rudder hard over. Depending on prop
rotation, the boat will be much easier to turn in one direction than
the other. I have seen large workboats turn around almost in their
own length using this technique.

Thanks to both of you for sharing your experiences. I am going up to the
GB later this morning and do some practicing.

Part of the learning curve (for me) is adjusting to the v-e-r-y slow
response to throttle or gear shift. I get a kick out of it, but it takes
some getting used to. A 36 GB is a heavy boat for a little 120 hp engine
and small prop, but it's fun learning how to deal with it. My head's
"tuned" for much more powerful boats with bigger props, etc. that react
rather quickly. I'll get there with some more practice.

BTW .... Wayne ...

The former owner of Mrs.E's boat ended up buying a 1990 GB 49 footer with
twins.
It's not high powered ... 15 kt cruise ... but it's a thing of beauty. He
spent all last winter traveling the southern hemisphere in it and recently
returned to Kingman for a short haul and cleaning before traveling off
again.

Cool.

15 kts *is* high powered compared to ours. We can cruise at 10.5 kts
when we need to but it's much more fuel efficient in the 8.5 to 9
range.

What kind of engines does he have?

What's the breeze like at 8.5 knots? :}

If it has an ignition or on-off switch .... I drive.
If it has a saddle and you feed it .... she drives.
