The instructions in this manual are made with the intention of making
owners safely use the boat for training and racing. The M32 is a high
performance competiton boat designed and dimensioned for inshore
racing and should be used accordingly.
WE WANT TO STRESS THE IMPORTANCE OF HAVING THE RIG ACCORDING TO THE RECOMMEN-
DED SETTINGS WITH THE SPREADER ANGLE, PREBEND, DIAMOND TENSION AND MAST RAKE
BEING THE KEY PARAMETERS.
•Spreader angle should be between
180-200mm
•Prebend should be a minimum of
70mm with full main and 80mm when
sailing with a reef. When measuring
the prebend the mast supports shall
be placed 150cm above the bottom
end of the mast and one 20cm above
the upper diamond stay fitting.
•The diamond tension using the Loos
& Co. gauge RT-10M(3,2-7,1mm) with
the base of the gauge in just above
the mast winch is recommended to be
in the interval 45-55. If the required
prebend is not reached at 55 on the
gauge the spreader angle needs to be
adjusted.
•Mast rake should be 480mm

ADDITIONAL IMPORTANT INFORMATION WHILE SAILING:
•The recommendation is that a max-
imum of one person tensions the
gennaker tack line. It is key that this
is not tightened excessively as it is
increasing the compression of the
mast dramatically.
•The forestays and shrouds should
be tight at all times so they need
to be tightened if they stretch. The
forestays take the majority of the load
going upwind, not the gennaker luff.
•When not manuevering only one dag-
gerboard should be fully down
•The mainsheet and traveler combined
is supporting the mast both upwind
and downwind and the gennaker
needs to be eased prior to the main-
sheet when depowering the sails.
•To prevent damage to the rudders do
not let the tiller go while reversing,
this is overloading the rudder head as
well as the blade.
•Ensure that the cunningham line
is not resting on the diamond stay,
a dyneema can be put around the
gooseneck to get a better angle for
the ring/block

Place the lower and upper mast tubes
collinear to each other either on stands
or padding on the ground.
Connect the spreaders to the mast; the
key ring shall be on the lower side. Only
the 2 Clevis pins closest to the mast
shall be disconnect when removing a
spreader.
The diamond turnbuckle needs to
properly greased and clean to function.
It’s a good opportunity to clean and
service the turnbuckle when the mast
is disassembled. Unscrew and remove
the bolt entirely, do not remove the
hanger from the mast. Clean the bolt,
bronze nut and washer. Put grease on
the entire thread of the bolt and bronze
nut + some grease on the washer. We
recommend “Rocol ANTI-SEIZE Stain-
less”. Other marine grease for stainless
should function.
Push the two mast halves together
and insert and tighten lightly the 6 M6
screw that locks the lower and upper
mast tubes together, (2 on the leading
edge and 2 on each side close to the
trailing edge).
Make sure that the mast halves are
a tight fit, if this is not the case this
needs to be ensured by bedding the
joint with adhesive

Attach the lower diamond on one side
to the diamond turnbuckle and then
connect it to the upper diamond at the
spreader tip. Support the upper dia-
mond to prevent unnecessary load on
the stay. It is good to have marked the
diamonds stays so one knows which is
starboard and port.
Attach the upper diamond to the mast.
The nut must be all the way down in
the hanger as shown in the picture,
this must be controlled while tensio-
ning the bolt to ensure that it is not on
the side.

Its important to lubricate the two halfes before
pushing them togeher.

Tension the diamond turnbuckle until you
get your required prebend.
Prebend should be a minimum of 70mm
with full main and 80mm when sailing with
a reef.
Prebend is defined in this case as the
distance between the trailing edge at the
spreader and an artificial straight line
between the upper most point and lowest
point of the trailing edge of the luff track.
When measuring the prebend the mast
supports shall be placed 150cm above the
bottom end of the mast and one 20cm
above the upper diamond stay fitting.

It is VERY IMPORTANT that the clevis pin is orientated with the head facing towards the trailing
edge of the mast and the key ring is towards the leading edge of the mast. The shrouds can be
damaged and the mast can fall down if the clevis pin is orientated the wrong way.
The halyards need to have a diameter
of 8mm to prevent the halyards to
come out through the luff track. Do
not remove the cover or use lesser
diameters.
VERY IMPORTANT!
IMPORTANT!
Remove the top sheave to insert the Main
halyard. Use a small hook to pull the haly-
ards through the luff track. Tie the sail head
end of the halyards to the mast close to the
mast foot.
Let the Gennaker halyard at the bottom go
through the spinlock on port side of the
mast.
The diamond tension using the Loos & Co.
gauge RT-10M(3,2-7,1mm) with the base of
the gauge in just above the mast winch is
recommended to be in the interval 45-55.
If the required prebend is not reached at 55
on the gauge the spreader angle needs to
be adjusted.
Let the Main halyard at the bottom go
through the block on starboard side and up
to the winch.

How to check the spreader angle:
Pull a string tight between the center of the
spreader tips and measure the distance
between the string and the trailing edge of
the mast at the joint. Standard measure-
ment is 190mm, minimum is 180mm and
maximum is 200mm. Larger spreader angle
will give more mast prebend. The adjusted
length of the spreader turnbuckles must be
the same on both sides. A halft turn on turn-
buckles gives approximately a 5mm change
in spreader angle. As shown in picture 7a the
string should be pulled just above the end
fitting on top of the diamond stay.

Position the two hulls with the two
beams in place.
Adjust the position until everything
lines up before putting in the beam
bolts.

Put grease on the entire thread of the bolts. We
recommend “Rocol ANTI-SEIZE Stainless”. Other
marine grease for stainless should function.
VERY IMPORTANT!
Position the trampoline in front of the
boat with the two fibreglass rods facing
forward.
Fasten the trampoline to the main and
aft- beam as the illustation below
shows. Tighten the net at the main-
and aft- beam first then tighten the net
along the sides.
Slide the trampoline in from the front;
you need to be two persons. Be careful
to not scratch the hulls with the
fiberglass rods.

Put in the 8 beam bolts with washer.
Tighten the 8 bolts until there is no play
left, there will not be a distinct stop.
Do not over tighten the bolts, the bolts
only needs to be lightly tighten but with
no play left between beam and hull.
Put in the 4 travel track bolts with
washer from inside of cockpit.
Tighten the 4 bolts until there is no play
left, there will not be a distinct stop.
Do not over tighten the bolts, the bolts
only needs to be lightly tighten but with
no play left between travel track and hull.

Lower the bowsprit gently and connect
the struts carefully before securing
with the pins. When the struts are
connected the bolts can be tightened
so there is no play between the strut
and hull. Do not over tighten as it will
damage the threads!
Attach the rudder assemblies to the
hulls and lock the locking arm with
the shock-cord. Make sure that the
stainless pin is clean so the rudder can
rotate easily and that it is completely
through the lower gudgeon.

Attach the bowsprit to the main beam;
lock the pin with the chock-cord. Check
that the tack pilot line is in place.
Leave about a 5mm gap when
tightening the bolts.
Attach the gennaker halyard to the
middle of the bowsprit and hoist the
bowsprit. Connect the bolts while hol-
ding the struts upright, do not forget to
grease the threads.

IMPORTANT!
The locking arm of the rudder
shaft shall face outward. The
groove in the plastic puck is
deeper on the outside. If the
locking arm is facing inwards then
the locking arm can unlock and
result in expensive repairs to the
hull. The schock cord needs to be
replaced regurarly to ensure that
the locking arm is secured in the
groove.
Bowprit and racks are assembled after the stepping of the mast. The mast cannot
be raised if the bowsprit is connected.
NOTE!
