III 9 - CUTTING THE BOOM PROFILE AND THE MANDREL TO LENGTH
III 9 a -H
OW TO CALCULATE THE LENGTH OF THE BOOM PROFILE
.
Case # 1: The PROFURL boom overall length should be the same as the one
delivered.
Case # 2: The PROFURL boom being delivered in over length, the opportunity may be
taken to make the boom longer.
Caution : changing the boom length could
affect the balance at the helm when sailing under sails. In this case check
that the aft end of the boom cannot touch the backstay or any other piece of
equipment on board.
In both cases please refer to drawing 9 for dimensions.
The PROFURL in-boom reefing system is delivered pre-assembled. The boom profile (15)
and the mandrel (16) may have to be re-cut to length to match the boat’s requirements
when fitting the system.
CAUTION : should the complete length of the boom profile be used, the
rear boom end fitting is just temporarily attached to the boom profile
for shipping. Please follow the rear end boom fitting assembly
procedure from § III 9 c 5 and on as if the boom profile had been re-
cut.
III 9 a 1 - To cut the boom profile (15) and the mandrel (16) to length, first dismantle the
rear boom end fitting (23) from the boom profile and pull out the mandrel (16) from the
boom profile.
