MOORING
Mooring a seaplane eliminates the problem of the
anchor dragging. A permanent mooring installation
consists of a heavy weight on the bottom connected by
a chain or cable to a floating buoy with provisions for
securing mooring lines. Approach a mooring at a very
low speed and straight into the wind. To keep from
overrunning the mooring, shut down the engine early
and let the seaplane coast to the mooring. If necessary,
the engine can be started again for better positioning.
Never straddle a buoy with a twin-float installation.
Always approach while keeping the buoy to the outside
of the float to avoid damage to the propeller and
underside of the fuselage. Initial contact with the buoy
is usually made with a boat hook or a person standing
on the deck of one float.
While approaching the mooring, have the person on
the float secure one end of a short line to the bottom of
a float strut, if one is not there already. Then taxi the
seaplane right or left of the mooring so that the float on
which the person is standing comes directly alongside
the buoy. The free end of the line can then be secured
to the mooring.
Exercise extreme caution whenever a person is assisting
in securing the seaplane. There have been many
instances of helpers being struck by the propeller. On

most floatplanes, the floats extend well in front of the
propeller arc. Eager to do a good job, an inexperienced
helper might forget the spinning propeller while walking
forward along the float.
DOCKING
The procedure for docking is essentially the same as
for mooring, except that approaching directly into the
wind may not be an option. The keys to successful
docking are proper planning of the approach to the
dock, compensating for the existing environmental
conditions, and skill in handling the seaplane in congested
areas. Bear in mind that a seaplane is fragile and
hitting an obstruction can result in extensive damage.
Plan the approach to the dock so as to keep the wind on
the seaplane’s nose as much as possible. While still
well clear of the dock area, check the responsiveness of
the water rudders and be sure the seaplane will be able
to maneuver in the existing wind and current. If control
seems marginal, turn away and plan an alternative
method of reaching the dock. While approaching the
dock, the person who will be jumping out to secure the
seaplane should take off seatbelts and unlatch the door.
When it is clear that the seaplane will just make it to
the dock, shut down the engine and let the seaplane
coast the remaining distance to encounter the dock as
gently as possible. The person securing the seaplane
should step out onto the float, pick up the mooring line
attached to the rear float strut, and step onto the dock as
the seaplane stops. The line should be secured to a
mooring cleat on the dock. Use additional mooring
lines if the seaplane will be left unattended. Be sure to
complete any remaining items on the checklist, and to
double-check that the mixture, magnetos, and master
switch are in the off positions.
BEACHING
Success in beaching depends primarily on the type and
firmness of the shoreline. Inspect the beach carefully
before using it. If this is impossible, approach the beach
at an oblique angle so the seaplane can be turned out
into deeper water if the beach is unsatisfactory. The
hardest packed sand is usually near the water’s edge
and becomes softer where it is dry, further from the
water’s edge. Rocky shorelines are likely to damage
the floats, especially if significant waves are rolling in.
Mud bottoms are usually not desirable for beaching.
To protect them from damage, water rudders should be
up before entering the shallow water near a beach. Sand
is abrasive and erodes any protective coatings on the
bottoms of the floats. If possible, beach the seaplane by
sailing backward with the water rudders up. The aft
bottoms of the floats do not dig into the sand as deeply
as the forward bottoms, so backing onto a beach is not
as hard on the floats as going in nose-first.
Do not leave the seaplane unattended unless at least a
tail line is fastened to some solid object ashore.
Moderate action of the water rapidly washes away the
sand under the floats and lets the seaplane drift. An
incoming tide can float a beached seaplane in just a few
minutes. Likewise, a receding tide may leave a seaplane
stranded 30 or 40 feet from the water in a few
hours. Even small waves may alternately pick up and
