This may sound like a really stupid question, but I honestly don't
know the answer.

Is it easier to manuever a boat with twin engines with two rudders?
What would be the difference if it had one rudder? Or if you have a
single engine and two rudders?

My guess is that you leave the rudders in straight forward neutral and
only
work the engines forward/reverse to maneuver.

Let's see if I am right.



I agree, although rudder position can be used along with forward/reverse
adjustments of the boat transmissions to do some pretty cool maneuvers.
Normally, when backing the Navigator into a slip I do as you said ....
rudders amidships and I "steer" the boat into the slip using the engines and
transmission positions. I don't even touch the helm.

When trying to dock against a dock and there isn't much room, you can make
the boat move sideways with the helm hard over and careful manipulation of
the throttles with one transmission in reverse and the other in forward. To
move sideways in the other direction, you reverse the positions of helm and
transmissions.

Takes a little practice, but on calm days I can move the 52 foot Navigator
sideways 10 or 15 feet without moving forward or backwards. A tug boat
captain taught me how to do it as he snerked at my thruster controls.

In close quarters maneuvering it's nice to have the prop wash blasting
directly against the rudder, especially important with a single engine
boat but useful even with twins. The rudder deflects the prop wash
and creates a lateral (rotational) force.

So if I read that correctly, and I might not be, using a single rudder
would be similar to applying vectored thrust as you do with an
outboard, but not so with twin rudders?

You get the equivalent of vectored thrust only when moving forward .... not
in reverse as in an I/O or outboard. Moving backwards, rudder position has
little or no affect on steerage. A single, like the GB, requires use of
the "back and fill" technique to back into a slip .... along with a little
bit of prop walk ... although on our GB the prop walk isn't much.

Rudders on twins, like the Navigator, also only work moving forward, but you
use the engines and transmission positions to "steer" the boat backwards
..... similar to how a bobcat is driven. Often, on large boats with twins,
you will see the captain standing and facing backwards, with his arms behind
his back and hands on the transmission levers. You don't use the helm, nor
rarely the throttles unless you get a bit of wind and need to straighten out
a bit.

Hey .... I assumed you've operated twin inboards on a larger boat before.
If you haven't ... come on up to Kingman some day and we'll take the
Navigator out and you can give it a whirl.

That's funny, from a distance they all look alike.



He's bustin' your balls.

Your 49 looks like a bigger version of our 36 and I agree, from 50 to 100
yards you couldn't tell the difference.

The previous owner of our GB has his replacement .... a GB 49 sitting at the
dock near where I am now sitting on the Navigator. It's a beautiful boat
with all the classic lines of a traditional Grand Banks, but with more room
and twin engines.

A Grand Banks style boat is something that you learn to appreciate and like
over time. Once you get beyond the standard "too slow, too much teak, too
much upkeep, too old" impressions and start to use it, you begin to
appreciate the tradition, quality and most importantly ... the experience of
seasoned boatbuilders.

There's a major benefit to not making major style changes every year like
mass production boats. All the kinks have been worked out over 40
something years.

Running a slow GB is simply a different type of boating experience and can
be quite enjoyable.

Nope - my experience is strictly with twin outboards on a wide beam
Contender.

I've been aboard inboard boats with twins, b ut never as Captain.

I will probably take you up on that - I'll drop you a note via email.

When I want to enjoy a slow boat, I take the canoe out for a spin on the
river. Not only is it quieter than a GB RV, there's no exhaust smell,
you're down at the water's level, and you get a bit of decent exercise,
too.

Nothing wrong with that .... I often do the same with my Kayak. Only
difference is, I can carry the Kayak with me where ever I go, I can return
to the GB and get dry when it starts to rain, cook up something to eat and
catch a nice, afternoon nap in the aft cabin.

Try that in your canoe.

Ahh, I keep my canoe out at the Shenandoah, at a friend's little farm.
When I return from canoeing, I can warm up by the fire, cook anything I
please, and take a nap in the hammock on the screened porch, or crawl
into one of the beds.

Why does this make me think of Goldilocks and the three old bears?

Starring Harry as Goldilocks?

Sure would explain a lot. :)

Yep. We "gots" bears, too.
