[Rhodes22-list] Tight Turns To Port With The Wind Astern

[Roger Pihlaja]

David,

Sorry to say this, but it sounds to me like your docking technique may have
contributed to your engine failure.  Repeatedly shifting from
forward-reverse-forward is very hard on an engine.  It's also a very
difficult way to turn a boat around, sort of the technique of last resort.
However, it sounds like you have one of the most docking difficult
situations; strong wind astern, right hand prop, & tight turn to port into a
narrow slip - YUCK!  Dynamic Equilibrium can make this turn under these
conditions in about 1.5 - 2 boatlengths by putting the rudder tiller hard
over to starboard & the engine tiller hard over to port with the engine at
full throttle in reverse.  Please note that you will have to disconnect your
rudder to motor steering linkage in order to perform this maneuver.  The
boat would need to be traveling at a starting velocity of about 3 knots
forward in order to pull this maneuver off.  So, your situation sounds like
it's right on the ragged edge of the performance envelope.  Before you try
this, make sure you have done everything possible to reduce your windage,
particularly at the bow.  Remember that you must maintain forward velocity
in order to have any steering control.  Although it can be daunting in a
crowded marina with the wind howling, if you are going to attempt this kind
of turn; then, this is not the time to be timid.  I think I would setup some
fenders for marker buoys out in open water & practice this maneuver before
trying it in the marina.  I know this manuever sounds radical, but try it.
You may get to like it & it will be a whole lot easier on your engine.

You might consider finding a different slip for next season.  For example, a
slip right across from you would be better.  A tight turn to starboard in
this situation is much easier than to port.

If it were my boat & I were being more cautious, I think I would pull up to
the end of the finger pier, port side to the pier.  I would either put out
fenders on the port side amidships or mount a suitable bumper on the corner
of my pier.  I would loosely tie off amidships & use a bow line to warp the
bow around into the slip.  No muss - no fuss.
