2.4.2. Beams
The beams are ready to go onto the boat, all beam bolts are numbered for their position in the
beams.
♦
Make sure that the rear and front beam are facing the correct way. On the rear beam the
eyelets for the traveller cord should be facing backwards. Apply sufficient grease to the
threaded part of all bolts before inserting them into the hull. Get all the bolts started before
tightening the 1
st
bolt. Be careful not to over tighten or cross thread the bolts. If a particular
bolt is being difficult to fit then fit this bolt first.
♦
Use a 17 mm hexagonal socket or a 17 mm spanner to tighten the bolts properly. The bolts
should be set to 20Nm using a torque
wrench.
♦
In case a torque wrench is not at hand,
a weighing clock (as used in fishing for
instance) connected to a 17 mm ring
spanner will do the job too. If the ring
spanner would have an effective length
of 0, 15 m, the clock should read 13.5
kg for 20Nm.
♦
Do not forget to check the bolts from
time to time as some setting will occur
during the firsts boating. In no case
exceed the recommended 20 Nm as
over tightening will result in a damaged
threads
♦
Finally, after the platform has been assembled, the dolphin striker needs to be tensioned.
Use a 24 mm spanner to extent the pole between the front beam and the striker strap. The
centre of the front beam should be 10 mm higher then on the ends. The front beam is then
bent up and slightly pre-stressed.
2.4.3. Trampoline
Fitting the trampoline might take some effort as it new and has not yet been stretched from use.
♦
The trampoline should already be attached to the front beam. If not slide it into the front
beam groove and refit the front beam end plate.
♦
Fold the trampoline upwards and insert the cords on either side in the track of the hull.
Adding a little Teflon or silicon base lubricant to the track and on the cord of the trampoline
will ease the work considerably.
♦
Slide the trampoline down the track on each hull. This is best done with 1 person on either
side of the platform and does require some care to pull the trampoline backwards. Keep it
even on each side as it moves down the hulls. You may need to help feed the tramp into the
track once it pulls tight across the boat. Finally slide the alloy tube into the pocket at the rear
end.
♦
Use the 3mm cord to lace the tramp to the rope buttons on the rear beam. Pull very tight as
you move across the boat. Use the rope buttons on the rear beam to absorb the surplus
length of the cord after tensioning.
♦
The shock cord for the skipper’s trapeze wires should pass underneath all other lines and
around the striker post.
♦
The righting rope should be attached to the front beam by passing outwards through a
saddle on either side with a stop knot and kept tight and flat in a V-shape backwards under
the trampoline by a shock cord running from the front beam, through an shackle at the rear of
the tramp. In this way, sufficient righting line is always available without having it on deck.
