III 11 - FITTING THE BOOMVANG HOUND AND THE BOOMVANG
Reminder: the ideal working angle of the boomvang being 45° the boomvang must not angle less than 30 °
with the mast or boom.
III 11 a - Fit the boomvang attachment (12) with the 2 slide screws which had been stored at the mast foot
(please see § III 2 a A ).
III 11 b - Bend the aluminium gooseneck sideplates (13) to the mast shape. During
bending please protect the plates from dings and dents.
III 11 c - Would the sideplates be too long, they can be re-cut if necessary, keeping in mind
too much length is always better than too little.
III 11 d - Draw lead lines for drilling on the side plates (13). Drill at Ø 5 mm and fit the pop
rivets (14) on the side plates . There should have at least 8 pop rivets (14) on the mast on
each side plate.
III 11 e – Fit washer 20 onto the articulation eye. Fit the articulation eye (49) with the eye preferably
downwards onto the gooseneck attachment, fit in this order washers 20 (plastic) and (SS) 30, low nut 30a
and Nylock 31 . Please see drawing 13.
Note - in some cases you maybe brought to fit the articulation eye
(49) upside down: providing the boomvang angle to the boom is still more than 30°, it is a mechanically
acceptable option.
III 11 f - Fit the boomvang onto the articulation eye (49) and onto the boomvang hound (28). Fit the pins and
the split pins.
