Installation Manual
Recommended Installation Tools:
Phillips Screwdriver; Fine Tooth
Hacksaw; Center Punch; Rule; Variable Speed Reversible Drill and Blue
Locktite.
1. Setup Boom Height:
Sliding goosenecks should be positioned
for sailing. Securing a stop under the gooseneck relocates the position
for rigging. Use the main halyard to support the boom above its highest
operating position, or a desired height when moored or docked. At this
time, check that the Model K0500 is correct. The min. length is 26 in
(66 cm) pin to pin and the max. weight it can support is approximately
14 lb (6.3 kg) measured at the outboard end of the boom with the main
sail flaked.
2. Position Boomkicker:
The Boomkicker works by flexing
upward and when straight, it is at the top of its travel. Install the
Boomkicker with the screw head side of rod clamps facing up to flex upward
away from the vang. With the boom height set, position the Boomkicker
with fittings alongside the vang triangle to see how it fits. Position
is not critical so long as it does not interfere with the vang. It's recommended
that both the vang and the Boomkicker make an angle of between 30o and
45o with the boom. Mark the location for the mast fitting.
3. Install Mast Fitting:
The mast fitting comes with
a luff grove slide to avoid drilling the mast. Different diameters and
flat slides are available by exchange, or at the web site or by phone.
See part list. If usable, a fter disassembly from the fitting, the slide
can o ften be inserted at the mast opening for the sail and dropped or
lowered with a string. If the mast is out of the boat, the slide may be
inserted from the base of the mast. Reassemble the mast fitting at the
desired location and tighten the screws. If the slide is unusable, the
bracket may be screwed directly to the mast. Extra long screws are included
if needed to pass through the groove. Use the #25 drill and the 10-24
tap provided, with the mast fitting bracket as a guide. A variable speed,
reversible drill makes tapping easy. Go slow. Locktite is recommended
on threads.
4. Shorten if Necessary:
If the Boomkicker is too long,
we recommend shortening the rods at the mast end so any cut ends are less
visible. Loosen the rod clamp with the provided hex-key and slide the
extension up the rods until there is a good fit. The bottom half of the
clamp fittings for each extension have embossed stops to prevent slipping.
Do not shorten total length more than 10 in (25 cm). Cut off extra rod
length equally from both rods with a fine tooth hacksaw. Before tightening
the clamps, check the rod ends are against the embossed stops and the
clamps/extensions are not twisted relative to each other.
5. Install Boom Fitting:
Make sure the rod clamps at
both ends are tight. Then attach the Boomkicker to the mast fitting, and
the slide and track at the boom end. The angle on the track goes forward,
the stop in a ft. There are 3 standard choices for the stop with the initial
position in the middle for later adjustment if needed. If necessary more
stop positions can be drilled using the inscribed line along the side
of the track for the 3/16 in diameter pin. With the Boomkicker in position
and slid back against the stop pin, and with the track centered under
the boom, mark one hole. Then center punch, drill and tap. Attach the
track, recheck position, then drill and tap the remaining holes using
the track as a guide. Use Locktite on threads. Hint: Once installed, to
attach the Boomkicker, it's usually easier to slide the Boomkicker into
the boom track first, then attach it to the mast fitting, rather then
attaching to the mast first.
6. Check Return Force:
A fter installation, check return
force by pushing down on the end of the boom. The amount of support desired
is a personal preference. For reference, with the sail flaked, using about
10 to 12 lb (4.5 to 5.4 kg) to pull the a ft end of the boom down seems
like a good balance between boom support versus tension required to pull
on the vang. More support may be desired with a bimini or if crew use
the boom for support with the sail down. Less support may be desired if
the mainsail is not stored on the boom or the Boomkicker is used to just
li ft the boom in light air for sail shape. If less or more force is needed,
optional spring rods are available either as exchange, or ordered on the
web or by phone. The purpose of the Boomkicker is to support the boom
so the boom topping li ft can be eliminated along with the chafe, windage,
hangups and adjustments. If needed in unique circumstances, such as motoring
in waves with the mainsail down, the main halyard can be attached to the
a ft end of the boom and tightened for further support.
