Hull assembly
Position the hulls in
parallel with the inner
sides facing the
ground.
Lift the right hull. One person
straddles the hull to hold it in
place. The other person ap-
plies the silicone sealant (for
waterproofing) around the
bolt holes.
Take the front
crossbar (with
dolphin stri-
ker). Place it in its
support so that the
trampoline track
faces the rear of the
boat. Insert the two
bolts. Pass your
hand through the inspection port to position the nuts
and washers onto the bolts photo). Fasten loosely. Lift
the left hull, and follow the same steps as for the right
hull. Do not fully tighten the screws. ***Respect same
order for the washers as assembled at the delivery***
Apply silicone sealant around
the rear beam bolt holes.
Place the rear crossbar on the
right side. Insert the bolts, washers
and nuts as shown for the front
crossbar. Do the same thing for the
left side.
Once the frame has been mounted,
tighten all the bolts fully and then
install the lock nuts.

NB : it is advisable to check the fastening of the bolts after the first trip out onto the water, and
recheck these at regular intervals.
2
washers
nuts
Unfold the trampoline. Note that the
side tension lines are prethreaded. In-
sert the front sealed bolt rope edge
into the trampoline track of the front
corssbar. Continue feeding the tram-
poline into the trampoline track and
position it in the centre. Line up the
grommet in the centre of the front
edge of the trampoline with the dolphin striker post. This will position the trampoline in the centre.
4
Pull the trampoline to the back of the boat and
insert the fibreflass rod into the rear flap of the
trampoline. Leave an equal amount protruding
from each side.
5

6
Trampoline
Commence lacing the rear of the trampoline.
The lacing line ties off on the lacing post at
the left rear of the rear beam. Pass the line
around the rod and back around the first la-
cing post. Lead the line around the second la-
cing post and pass it around the rod on the
first trampoline cut out. Now, come back
around the second lacing post and continue
towards the third. Continue all the way across the beam in the same fashion and tie off
loosely. Do not attempt to tighten the rear lacing too much at this stage.
6
Start
Now lead the end of the line through the eyestrap on
the rear of the front beam and back through the loop.
Lead the end back through the eyestrap and apply as
much tension as possible. Maintaining the tension,
lead the line through the grommet and back to the
eyestrap. Next, lead the line through the grommet in
the front edge of the trampoline and tie off securely.
Repeat procedure for port side.
Tensioning the
sides : starting at
the right rear cor-
ner, take the line
that emerges
from the trampo-
line. Lead it
through the eye strap on the rear beam and then
through the grommet/eyelet. Tie it off with a bow-
line knot or similar.
7
Move to the front right
corner of the trampo-
line. Pull on the line
as firmly as possible
and tie a bowline knot
or loop in the line as
close to the trampo-
line edge as possible. This will enable a 2:1 pur-
chase to be used for tensioning. Tie off once ten-
sioned to secure.
8
9
Retighten rear lacing from left to right. Tie the rear la-
cing off securely at the eyelet posts on the right hand
end of the rear beam.
NB :
It is important that the trampoline lacing is
kept very tight. Check the trampoline tension on a
regular basis. Remember: all ropes streches!

Tiller crossbar & tiller extensions
Insert the rudder pin, and do not forget to put in the
two split rings: one on top and one at the bottom of
the rudder pin.
Repeat the proce-
dure for the right
rudder
assembly.
Identify the right rudder from the left rudder (green sti-
cker = right ; red sticker = left)
Take the left rudder, position the washer as indicated on
the photograph, then align the rudder casting onto the
gud-
geon
.

Take the yoke connection of the tiller extension and fix it
into the middle of the tiller crossbar.
Take the tiller crossbar and insert the right side
into the right rudder arm and the left side into the
left rudder arm.
4
5
Then fix the tiller head into the yoke connection as
shown on the photo.

Unroll the diamond wires. Attach the joint end of the
diamond wires onto the turnbuckle adjuster near the
base of the mast (level with the security sticker) using
the pin and split ring.
Take the loose ends of the diamond wires and hold tight to
adjust to the same length, using the turnbuckle adjuster
which is located on the lower section of one of the wires.
Once they are the same length, attach the two wires to the
shield plaes situated on each side of the mast under the
mast tang.
Assemble the spreaders on the centre of the
mast. The spreader root attaches to the front
of the mast section onto the one-piece stain-
less steel strap. The spreader rake adjuster
barrel attaches on each side to the individual
fittings on both sides of the mast nearer the
sail track. To adjust the spreader rake, adjust
the length of the barrel (by winding in or out)
and measure from the wire positions at the
tips of each spreader. Caution : do not try to
adjust spreader rake while diamond wires are
Slide the diamond Wires into the correspon-
ding slots at the end of the spreaders. En-
sure the black plastic roller is above the
spreader arm. It may be necessary to re-
lease tension from the diamond wire turnbu-
ckle adjuster near the base of the mast. Se-
cure the diamond wire with the thin wire
supplied. Pass the wire through the small
hole near the spreader tip, bend the wire
and on one side of the spreader turn the
wire around the thicker diamond wires two
or three times. Do the same for the other
side of the spreader. Cut off the excess thin
wire ensuring it is bent neatly onto the dia-
mond wires as to prevent the wire from tea-
ring the sails. Once secured, tape over the
spreader tips to further ensure there are no
sharp edges.

Raising the mast
Attach the twist toggles
and stay adjusters to
the shroud anchor pins.
Locate the two shrouds, two forestay/bridles
and the two trapeze lines. Unroll all the wires
and remove any kinks. Attach the loop at the
top of the trapeze lines to the thimbles at the top
end of the shrouds.
1
Attach the wires to the mast tang with the 8
mm shackle. The two forestay/bridle wires
are located between the two shroud wires.
See photograph. Tighten the shackle with pliers.
Re-check the tang shackle regularly !

3
Attach the re-
maining two
stay adjusters
to the bow tangs.
4
Rotate the mast 90°
and place the mast
base onto the mast
step ball. Secure in
place using the bolt
and nut supplied.
Lay the shrouds
and forestay/
bridles down
each side of the
mast on the tram-
poline. Attach the
shrouds to the
top holes in the
shroud adjusters.
The trapeze lines
can be fastened
loosely near the
base of the mast
if desired.
6
Lay the
mast on top
of the boat
with the sail
track facing
down and
the mast
base to-
ward the
bows. Tip : Disconnect one side of the tiller cross-
bar and swing it to one side. Use some padding
under the mast to prevent scratching.

Trapeze
CAUTION - DANGER - ALUMINIUM MAST
STAY AWAY OF ELECTRICAL WIRES
Before raising the mast ensure that it cannot
get in contact with electrical wires
The person on the trampoline now pushes
the mast into the fully upright position and
holds it in position. TIP : The second per-
son may assist in the above procedure. Once the
mast is in the fully upright position one person is
sufficient to hold it there.
With one person on the trampoline and the
other toward the head of the mast, start lif-
ting the mast until the person on the trampo-
line can support the full weight.
1
2
Release the trapeze lines from the base of the mast and ensure that they are
not tangled. Pass the trapeze shock cord under the trampoline and up
through the grommets behind the daggerboard shock cord. Assemble the tra-
peze adjuster line, rope locks, and trapeze lines and attach to the shock cord.
Trapezing height can be altered by adjusting the position of the rope lock on
the trapeze adjuster line.
The second person can now take the fores-
tay bridles. Make sure that they are not tan-
gled and attach them to the stay adjusters on
the bow tangs.

FIXING THE TRAPEZES

11
*Always point your Hobie into the wind before raising the sails. *
Unfold the mainsail on a clean surface and insert each batten into its respective pocket. The
battens are numbered from 1 to 7. Number 1 goes at the top and number 7 at the bottom of
the sail. Secure the battens in the pockets with the batten ties – as shown in the photo-
graphs.
1
Mainsail
Undo the halyard rope, which is attached to
the mast. Pass the end through the hole in
the headboard and tie off with a figure
«8» knot.
2
Feed the luff of the mainsail into the opening of
the mast track ensuring that the hook is on one
side of the mast and the halyard on the other
side. Ensure that the halyard inside the track
stays inside the track.
Raise the sail by pulling the halyard and feeding
the sail into the opening. When the sail is all the
way up turn the mast slightly so that the hook
will engage in the halyard lock when you pull
down on the sail. Insert the bottom part of the
luff into the lower section of the mast track. Roll
up the halyard and place it in the trampoline pocket.

12
Boom
Slide the outboard end of the boom through
the webbing loop attached to the clew of the
mainsail.
1
Connect the boom to the mast using the
hinge vertex, clevis pin and split ring.
2
Connect the shackle on the boom outhaul
line to the grommet in the clew of the main-
sail.

13
Mast rotation
Locate the rotation line. Pass one
end through the end of the rotation
arm. Both ends of the line go down
through the grommet located in
the middle of the trampoline be-
hind the trampoline pocket.
1
Lead one end of the rotation
line under the trampoline and
up through the grommet loca-
ted adjacent to the deck-
mounted rotation cleat. Pass
the line through the cleat fair-
lead and tie off at the stay ad-
juster. Repeat procedure for
other side.
2

14
Take the righting line from the rope bag.
Attach it to the dolphin striker post under
the front crossbar (photo). Pass it under
the trampoline through the grommet at
the base of the mast. Fold up the end of
the line and stow it in the trampoline po-
cket at the base of the mast.
Shackle the cunningham blocks into the grommet of the mainsail tack. Take the cunningham line and
feed as follows : (NB : the line must go through the inside of the rotation arm)
- Start from the cunningham block ont the left side of the mast. Feed the rope into the cleat around the
sheave
- push the cord up through the first sheave of the left block from back to front
- take the rope back down, thread it through the left sheave at the base of the mast from front to back
- take it up through the second sheave of the left block from back to front
- take it back down and through the single block,
- take it back up into the first sheave of the right hand block from front to back
- take it back down through the sheave at the right of the mast base from back to front
- take it up through the second sheave in the right block from front to back
- finally thread the line through the cunningham block and in the cleat.
Attach each end of the cunningham line to the shrouds.

Jib kit
Mounting jib sheet tracks
The inboard end of the track is located 320 mm from
the centre of the front cross beam and 40 mm up from
the trampoline slot. Use the pop rivets supplied to ins-
tall the track. Do the same thing for the second track
on the opposite side. Slide the jib sheet block/car as-
semblies on to the tracks.
Attaching the pigtail, forestay and jib halyard
When using the jib kit on the FX-One, the two long forestay/bridles
supplied with the cat-rigged boat are not required. Undo the 8 mm
tang shackle, remove the two forestay/bridles and shackle the pigtail bet-
ween the two shrouds. Fit the two extra trapeze lines to the shrouds if re-
quired.
1
Mounting the furler cleat
The cleat is located 180 mm to the left side of the
centre of the front cross beam and 55 mm up from
the trampoline slot. Use the large wedge only and
also the metal fairlead. Fasten the furler cleat to the
beam using the self tapping screws supplied.
2
3
Attaching the bridles and furler
Connect the bridles supplied with the jib kit to the bow tangs.
Fasten the inboard end of the bridles to the furler. Ensure that the hole in the furler housing is pointing to-
wards the front cross beam. Now is a good time to roll some line
onto the furler drum.
4
Raising the mast
Attach the jib halyard line to the small jib halyard
block at the end of the jib halyard wire. Tie off the ha-
lyard wire and the line near the base of the mast.
5

17
Once the jib is fully raised, take the jib luff
tensioner line and secure it to the bottom
of the stay adjuster.
Now pass the line through the small block at the
end of the jib halyard, then back down through
the cleat on the jib tack. Remove the jib halyard
line and stow it in a secure place.
NB : Ensure that the rig is tensioned before
you tension the luff on the jib. The jib
halyard is designed to tension the luff of
the jib - not to support the mast.
Jib kit
Hoisting the jib
Unfold the jib and open the zipper on
the luff. Use the 4 mm bow shackle to
connect the jib tack to the furler moun-
ted stay adjuster.
7
Shackle the jib head to the jib halyard.
Then position the jib and the halyard line against the forestay.
Close the top of the zipper ensuring that the
halyard line and the forestay remain inside the zipper.
As you pull down on the halyard line,
close the zipper as the sail is raised.
8
9
Raise the mast and fasten the
forestay into the furler mounted stay
adjuster with the clevis pin and split ring.
Attach the trapeze shock cords, lines, rope locks
and handles if you have fitted the second trapeze kit.
6

18
Jib kit
Shackle the two jib clew blocks to the jib clew plate
using the shackle provided.
10
Jib sheet line
Take the jib sheet (yellow) and tie one end to
the becket on one of the jib sheet blocks
using a bowline knot.
11
Take the other end of the sheet and pass it through
the corresponding jib clew block. Now pass the line
through the sheave, then the cam cleat on the jib
sheet block.
Pass the jib sheet behind the mast (but above the cunnin-
gham lines) and duplicate threading procedure on the
other side of the crossbar.
Take the end of the furler line and lead it through the fair-
lead and cam cleat on the front crossbar. Pulling the furler
line will furl the jib, provided that the jib sheet line is not
cleated.
NB : it is not advisable to leave the jib furled for extended
periods of time.
12

19
Jib sheet (self tacking system)
Take the white
spectra rope
and to one end
tie on to the top
of the middle
size block.
Now take the yellow thicker sheet rope and starting from one
swivel cam cleat on the front crossbar pass the rope under the
thinner white spectra rope through the middle size pulley (2)
and back to the other side swivel-
ling cam cleat (also on the front
crossbar).
Once the jib is hoisted, attach the
carbo block (5) with shackle to the
jib clew and use the yellow sheet
rope to trim.
Firstly, attach the smallest pulley supplied in the kit to
the spinnaker pole centre pad eye (also where the
centre supports attach for the spinnaker pole). Attach
this pulley with one of the shackles supplied.
1
Lead the other
end of this rope
through the smal-
ler pulley that was
shackled to the
spinnaker pole in
step 1.
2
then back to the
carbo pulley atta-
ched to the travel-
ler car on the self-
tacking track.
3
This spectra then passes
through the other carbo
block (also supplied in kit
which attaches with shackle to the
jib clew) and then ties off to the
carbo block mounted on the travel-
ler car. Tie a bowline knot through
the hole in the middle of the pulley.

Further Suggestions
⇒To furl the jib you will need to untie the knot on the traveller car for the jib and tie the sheet off to the jib
clew block. Otherwise the jib will not furl completely.
⇒As the track is mounted on the front section of the beam you may find that the hole you use on the jib clew
board may now have to become one of the lower, more forward holes. Also it may be necessary to tack
the jib at a lower position on the forestay adjuster.
⇒The spinnaker halyard system still works exactly the same as the standard Hobie Tiger original system
however it has moved to a more outboard position on the beam.

20
Attach the Spi halyard block
Shackle the spi halyard block through the small
bow shackle attached to the thin cord at the top
of your FX-One mast. Now pass the halyard through
the pulley and thread as per the photograph.
Mounting the spi pole
First drill and rivet to attach
the spi pole mount bracket on
the center front side of the front
cross beam. Attach the base of the
spi pole to the bracket.
Then attach the spi pole bridle and support
wires to the bow tang using the shackles pro-
vided. Once the mast is erect and the rig ten-
sioned, using the spi pole support line lift the pole
and tension till firm. Ensure that the main bridle
wires do not loosen at this stage.
Attaching the bridles
Having already removed
the standard forestay/bridles, attach the
new short bridles to the bow tang on the inside
bow of each hull. The other ends of the bridles
both attach to the 6 mm shackle which also
connect to the stay adjusters.
Kit de spinnaker standard (Option)
1
Mounting the forestay
Replace the standard forward forestay/bridles with the
one forestay at the mast tang fitting. The new forestay po-
sitions between the side shrouds.
4
Now attach the spinnaker ratchet
pulleys to the shroud base toge-
ther with the twist toggle (except
Tiger & Pacific, on the padeyes on the
hulls).
Once attaching all the stays correctly
as per the rigging manual and checking
that there are no over head power lines
raise the mast.
3
Mounting the spi halyard cleat
Drill and rivet to attach the swiveling cam cleat
to the top of the front crossbar on the right side
of the mast step. Location 180 mm right from
the mast step (see diagram).
