There was only one reasons I
could ever come up with on Bathtub Mary... The boat had a mind of its own
and I hated it when it started to think ;-)))

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. (Protected marina,
no real current to contend with)</font></font><font face="Arial"><font size=-1>
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></font><font face="Arial"><font size=-1>Regards,</font></font><font face="Arial"><font size=-1>Brian

<font face="Arial"><font size=-1>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></font><font face="Arial"><font size=-1>Jim
