Sailing Techniques
Beating,
Reaching and Running
Beating
Light Winds - Don’t pull the sail in too tight as the boat stalls
easily at slow speeds. Keep the tiller central and as still as possible to stop
the rudder acting as a brake. Keep weight forward to lift the stern out of the
water and keep the boat heeled so that one sponson is always out of the water,
to reduce friction. Keep still in the boat to avoid disturbing the wind and
water flows.
Medium Winds - Pull the boom in over the transom corner but be careful
not to oversheet and stall, when there will be a dramatic speed reduction and
you may end up head-to-wind. [to recover from this, see page 2] Use short
tiller movements to luff slightly over the waves and bear away down the front of
them.
Heavy Winds - If the boat is struggling, ease the boom out a little.
Look upwind for gusts approaching and be ready to spill wind or luff slightly
to keep the speed up. Lean to windward to stop the leeward sponson from burying
and be careful not to point the boat too high and get “into irons”, stopped
head to wind, as it is very difficult to get going again if the boat stops.
Reaching
Light Winds - Keep easing the sail out until all the telltales are streaming
horizontally. Keep the tiller as central and still as possible. Keep one
sponson out of the water at all times, preferably by leaning to leeward, as
this will allow gravity to swing the boom out.
Medium Winds - Constantly check and re-trim the sail to keep the
telltales flying. Surf on the waves by bearing away as crests come under the
boat and luffing off them as they go by. Lean to windward, as you ease the sail
and steer to bear away, which lifts the leeward sponson to take advantage of
hull steering.
Heavy Winds - Waves are larger and medium weather technique is applied
more vigorously. If the leeward sponson submerges in gusts, luff a little to
ease the pressure and bring it up again. When using the rudder frequent small
movements are more effective than large ones as the rudder gives more control
and is less likely to stall. It also takes less strength and energy. When
bearing away, make sure to let the sail out quickly so that it doesn’t try to
resist the turn.
Running
Light Winds - Ease the sail out to 90-100 degrees from the centreline.
This should keep the boom out when you heel the boat to windward. Sailing by
the lee, with wind streaming from the back to the front edge of the sail, is
fast. Try to make some of the telltales fly to show the wind flow. It is
essential to fit gybing lines so that the rig can be trimmed in and out, as
required.
Medium Winds - Boom out to 90 degrees [marks on the mast and deck will
confirm the angle]. Boat heeled to windward and surfing on the front of waves is
fast. Speed is not increased by broad-reaching so point dead downwind or sail
by the lee for the shortest distance between two points. Weight should be kept
forward to trim the hulls level as, the longer the water line, the faster the
speed that can be obtained.
Heavy Winds - Concentrate on surfing down the waves and keeping maximum
speed. If the boat tries to bear away, pull 2 or 3 handfuls of sail in, which
should counteract it. Sliding seats can be pushed back to keep the stern down
and the rudder in the water but make sure the stern doesn’t drag as it will
slow the boat, which will make gybing more violent and put a strain on the rig.
Sitting in a semi-lying position feels more secure in big waves.
Centreboard Control
The centreboard is quite large and has considerable drag
when lowered. To avoid drifting sideways, the board should always be swung
fully down when beating. On a reach,
the board can be lifted as much as required, depending on the exact point of sailing
and the weather. It is often possible to raise the board so that only the tip
is down because the long narrow hulls give good directional stability on their
own. When running, the board can always be lifted right up and the reduced
friction makes a big difference to the speed.
Both centreboard
and rudder should be frequently checked and should be smoothed and polished to
reduce friction in the water. The board should be a snug fit in the slot, with
no sideways slop.
Steering
The system should be taut with no slop. Check the tightness
of the tiller pivot by moving the arm up and down and tighten if necessary. The
lines should be as tight as possible without any friction drag and it is
important that the tiller and rudder are both aligned fore-and-aft. The blade
should have no sideways movement in the stock but should pivot up and down
easily using the control lines.
