schlackoff, congratulations on your flip-flop. from instant one I have been
saying the boat MUST be moving for the rudder to be effective in reverse, while
you kept saying No the prop pulls enough water forward to make it work.

at least I am glad you saw the light. interesting how you changed position and
claimed it as your own all along.

t can
also be applied to moving ahead,

no, it can not. water *pushed* over a rudder can cause a rudder to turn a
boat, while water "pulled" over a rudder can not.


Jax, quit worrying about push and pull.
Take a sailboat and start backing it with the engine.... get up the right
amount of speed and shut down the engine. You can now steer that boat because
of the forces of the water PASSING over that rudder, exert a steering force.
Hoist sails and trim them to start getting headway (you are not pushing water
over the rudder you are passing water over the rudder) and once you have
sufficient speed, this water passing over the rudder will exert a force to
steer the vessel.... hence it applies astern or ahead.
Too simple for you to understand? ...... oh well......
