Picking up a mooring buoy
Using the stream to your advantage makes for easier
mooring.

Let's face it, picking up a mooring buoy really isn't
rocket science.
Yet somehow, we often manage to mess it up: witness those
unseemly scenes where the crew is hanging off the pulpit
frantically clinging on to a rope while their arms are
almost wrenched out of their sockets.
Much shouting and grappling later, the boat will be attached
to the mooring buoy, but skipper and crew are no longer on
good terms.
Use the Stream to your advantage
Imagine you are adrift in a river with a current flowing
at two knots. You will have no steerage or any other control
over the boat, but you will still be in danger of hitting
rocks, buoys, anchored boats or anything else fixed to the
ground - and you will hit them at two knots, the speed of
the stream.
This is not a great situation. But if instead you turn to
point the boat upstream and motor ahead at two knots, you
will find yourself in the happy position of having zero
impact speed with those same objects and, with two knots of
flow passing over your rudder, you will remain in perfect
control.
So, the first and most important golden rule is to STEER
INTO THE CURRENT.

Approaching downstream, boatspeed and stream combine.
Speed over the ground is increased. An upstream approach,
however, will reduce the speed over the ground.
Wind over tide
Having given you a golden rule, here is a situation where
you might be tempted to ignore it. A strong wind blowing in
the opposite direction to the stream might make you rethink:
DON'T. Always steer into the stream.
In this example we're motoring towards a mooring buoy
facing a 2 knot tide, with a near gale blowing from astern.
The wind is pushing us forward at an alarming rate.
At 20 metres from the buoy we engage reverse gear to slow
the boat down. At 5 metres we increase the reverse thrust so
that the boat is slowed further until the bow is held
stationary over the buoy.
Even though we are using a lot of reverse thrust to hold the
boat against the wind we still have 2 knots of positive flow
over the rudder and, therefore, retain full control.
It's worth noting that single screw motorboats with small
rudders and big propellers may not enjoy much control by
rudder alone, though the principle holds good.

It helps to pick some visual references when making your
approach.
Securing to Buoys
Mooring buoys come in many shapes and sizes but those
reserved for visitors will be large, clearly visible and are
often marked as such. They may sometimes have pick-up buoys
attached.
If the mooring has a pick-up buoy then approach up-tide
with a crew on the foredeck armed with a boathook. Remember
that the buoy will disappear under your bow as you approach,
so ask the crew to call out the distances while pointing at
it with the hook.
Once the boat has been brought to a halt with its bow
over the buoy, your crew should sweep under the pick-up
buoy's line with the boathook, pull it aboard - ideally
over the bow roller or through a fairlead - and secure it
to a cleat. You can then relax and put the kettle on.
If there isn't a pick up buoy, the easy way to do it is
to use a lasso. Take both ends of a long and heavy mooring
warp and cleat them to the boat with 'figure of eights',
which can always be undone even under load.
Pass the large loop of rope out over your bow roller and
then back aboard over the rails. The foredeck crew should
now divide the loop of rope into two even handfuls and, when
the helmsman brings the boat to a halt, cast the rope out
and over the buoy.
As the rope settles and sinks, back away from the buoy
and the rope will pull tight around the chain beneath the
buoy.

Whether by lasso or boathook, if you have to pick up a
mooring single-handed, make the initial connection over the
stern where you can both drive the boat and reach the buoy.
Once you have your temporary connection, take a long warp
from the bow to the buoy, release the stern and allow the
boat to swing. Finally, pull the bow up to the buoy and
secure.
