Meant to type "Lookie here" .... anyway, the link describes gyroscopic
progression which is why JohnH was correct.

I am new to boating and would like to get some opinions on docking and
how it "should" be done. I have a Wellcraft 270 Coastal with twin
Evinrude 200's.

The big issue with twin engine outboards is that the engines are are
usually mounted close together, and the props are relatively small.
As a result, most twin engine maneuvering tricks don't work
particularly well or take longer than you'd like.

Get some practice in open water and find out what works on your
particular boat. If you want to spin quickly to port, put the
starboard shifter forward, and the port shifter in reverse. In
addition, turn the wheel hard to port for some vectored thrust.
Everything is opposite for spinning to starboard. Be wary of trying
to spin the bow into the wind in close quarters.

Wind is not your friend on a lighter boat and you need to maneuver
quickly and decisively, all the time controling your speed to the
minimum required to accomplish all of that. It can be a delicate
balance at times and requires practice.

He's correct. Same on a motorcycle. Push the left handle forward, the
bike will make a left turn. Push the right handle forward, bike turns
to the right.

Try it sometime.

Hmmm. Actually push the left side of the handle bar away from you while
pulling the right side towards you and you go right.


No. On a moving motorcycle, (and I assume a bicycle, although I haven't
tried it) pushing the left handle away from you will cause the motorcycle
to turn towards the left ... same side that you are pushing. Push on the
right ... bike will turn towards the right.

I can see several people are having trouble with this. Don't feel bad.
So did I until I tried it.

Eisboch

I've never ridden a motorcycle. But if I'm on my bicycle and I push on the
left hand handle bar, or pull on the right one (rotating the handle bars
clockwise as viewed by a bird flying by) and the bike turns right.

I still cannot comprehend how adding a motor causes the opposite.

Nothing to do with the motor.

There are a lot of factors in play when you make a turn on a two-wheeled
vehicle.
Try this sometime on you're bicycle. Ride along, nice and straight and
without leaning.
As you pedal along, gently push one of the handlebars away from you. (no
leaning)
Note which way the bike tries to turn.

Ok I just did.

Pushing the left handlebar forward moves the front wheel to the right.

Pushing the right handlebar forward moves the front wheel to the left.- Hide quoted text -

Did you take into account the shifting of your weight in order to
"push"
(down?) on the left handle bar?

I think it has to do with the shifting of weight to the side you are
"pushing" on.

Yep. The only exception is with high speed racing motorcycles, bikes or
cars going into turns on a dirt or otherwise slippery track.

I was never talking about those conditions.

Every bicycle I ever used turned right when I pushed the left side of the
handle bar away me. Every motorcycle I ever owned did the same. Thus my
analogy in my original post.

I never thought my original post to this thread would evolve into dirt bike
racing maneuvers or disagreements on how to ride a bicycle.

'nuf said. ;-)

Okay, I'll vouch for Eisboch. Except I always thougnt of it as push on the
hand grip that is closest to the pavement and you'll turn in that more
sharply in that direction... and if for some reason the handlebars should
snap back in the opposite direction you will be launched @ss over tea kettle
over said handlebars.

Aren't you talking about 'drifting'.. as you might see on a dirt racetrack?

No.

I guess you all will have to just go try it. It's due to the gryoscopic
stability of the bike.
Now .... did you know that helicopters were impossible to fly until
gyroscopic progression was recognized and accounted for in the control of
the rotating airfoils?

Somehow boating will tie into this somewhere.....
