<DIV><FONT face=Arial size=2> OK, so explain to me. When my slip was
on the south side of the east-west pier, with a predominant southwest to west
wind, and I reverse out to the south,the stern would always go to port. Last
season, I moved to the north side of that same east-west pier, still predominant
southwest to west wind, and now when I reverse out to the north, the stern
always goes to starbord. Same boat, same engine, same prop, same procedures,
same operator, same predominant wind, different direction, different result.

<DIV><FONT face=Arial size=2> It appears obvious to me that the
direction the boat backs to has more factors controlling it than just prop
rotation direction induced prop walk.</FONT></DIV>

<DIV><FONT face=Arial size=2>Don't blame the prop walk on two blades.
The increased prop walk is more from being able to spin it faster. Those
that have converted to diesels and get even more RPM on the prop in reverse
get some very usable prop walk. In fact the prop walk effect is probably
the best way to steer when backing. Assuming your boat backs to port
(this can be different with a diesel) keep the tiller hard over for a
right turn and by backing and filling, you can do a 360 in little more than
the boats length. Back - the stern goes to port. Give it a goose
ahead - the prop wash against the rudder nudges the bow to the right. As
soon as she starts going ahead, back hard for a few seconds - the stern jumps
to port. Keep it up and it is easy to turn around. Note that
this can be slow with the Atomic 4 and the original prop.</FONT></DIV>
