Over recent years we are pleased to have supplied the
majority of sails to Formula 1 owners and which have won the
National Championships on several occasions.
The Formula 1 is easily overpowered and requires a mainsail
which can be easily flattened. This allows full main to be
carried into stronger breeze and gives greater flexibility in
The genoa is developed to respond easily to halyard tension
making it useful over the widest possible wind band. This year
we have introduced a pentex taffeta genoa and modified our sail
shape and panel layout to take advantage of the superior
properties of this cloth.
Our Formula 1 sails have been used for such diverse applications
as a round Ireland circumnavigation and even a self tacking jib
for single handed sailing.
For the spinnaker we have developed a sail based on our
successful Sonata design.
The No 2 genoa is built from 6.5 Polykote with maximum length
leech battens to give stability when the breeze is up.
Headsails can be provided for foil or hanks now allowed under

FORMULA 1 TUNING GUIDE
Cap Shroud Tension= 38
Lower Shroud Tension= 35
(Measured on Small superspar gauge)
To set mast rake
Backstay should be released during this procedure
Pull tape measure up main halyard and measure 8.2m to top of
boom black band.
Now measure to transom 10280mm
Front face of mast to forestay 2165mm
Upper Diamonds - Just slack
With backstay released the mast should set with about and inch
of prebend. Adjust tension of lower shrouds to achieve this if
When setting the mast up always apply cap shrouds before lowers.
Hang a measuring tape on main halyard and measure to shroud
platesto ensure mast is upright athwartships. Tension lowers to
eliminate sideways bend.
No 1 Genoa Sheeting
Tension halyard to have just enough roundness in entry to make
the windward and lee telltails lie down easily. Too slack and
the entry will be very flat, too tight will round up more than
required. The flattest entry which allows the boat to be
comfortably steered will give highest pointing.
Sheet lead position. Use this guide to determine correct
Sheet genoa until luff telltails lie down correctly with the
sail sheeted in on windward course. From this point you can
a) move leads forward, which will require you to ease sheet in
order to make top telltails flow. This will make the boat foot
faster but point lower.
b) move leads aft which will require you to sheet harder to
bring the upper jib leech back into position - This will make
the boat point higher and go slower.
When fully sheeted in the genoa leech is designed to set about
50mm from spreader. Obviously in light winds or in waves this
distance must be increased.
Use no kicker, sheet to C/L or above to bring boom close to
centreline. Tension miansheet so that upper batten telltails
flow intermittently. Backstay should be totally slack. Outhaul
With the boat fully powered up with full crew on rail genoa
halyard will probably need to be tensioned a little to control
sail shape. When overpowered, tension kicker and gradually
increase backstay. Leave traveller on centre if you wish to
de-power. Sail on mainsheet, increasing tension on backstay and
kicker as the wind increases.
Gradually increase kicker and backstay and move genoa cars back
If you free off mainsheet and boom will not move to leeward but
just backwards then slot is becoming choked. This is a good
indication of genoa cars requiring to come back.
You should be able to drop boom off C/L by 6 or 9" with No1 when
getting overpowered. This will take the helm off the boat. Move
cars back as necessary to allow this.
Sailing upwind with No2 Genoa
Sheet main hard down to traveller and let traveller go to
leeward use backstay and kicker evenly as required - pull on
cunningham to tidy up mainsail.
High pointing is achieved in less than overpowering conditions
by having a closed genoa slot and hard mainsail leech whilst
still retaining flow over the rig.
Once the sails stall significantly then obviously the boat will
slow down. In very light conditions, high pointing generally
equates to not making leeway. Often it is faster to crack off
and go lower. The extra speed generates more lift over the keel
and the boat actually makes less leeway.
In strong winds when the boat is generally overpowered high
pointing again equates to minimisation of leeway. This leeway is
incurred when the boat is knocked over. Being able to drop the
boom off the centreline a little (which you will find unloads
the helm) is important. This allows you to drive without putting
the brakes on with the rudder.
We sail upwind with the outhaul on in all conditions. If the
conditions are very lumpy and you need more drive you could ease
by 20mm or so. Downwind ease off.
