Minimum Pin to Pin: 88.9 cm
Maximum Force *: 136 kg
Maximum Stroke 1: 38 cm
Maximum Stroke 2 **: 15.3 cm
Boomkickers use two coated solid fiberglass spring rods to provide the force necessary to support the boom and mainsail.
The rods are clamped into teflon anodized aluminum end pieces and attached to universal mast and boom fittings. Fittings are included along with machine screw fasteners, the proper drill and tap and hex wrench. The mast fitting includes a round slide which, used in the luff groove, avoids drilling into the mast.
Flat slides in varying widths are available from the factory. The slides can often be inserted at the sail opening above the gooseneck and slid down reassembling the fitting in position. If slides are not usable, the fitting can be attached directly to the mast using the same drill and tap provided for the boom.
The custom extruded boom track is contoured to fit both round and flat bottom booms. The track has an adjustable clevis pin to set the maximum height the Boomkicker will lift the boom. The track length forward of the pin allows the boom to move higher if needed.
Boomkicker K0800: Includes mast fitting with round luff groove slide, Boomkicker with 9/16 in diameter spring rods, boom fitting track assembly and fastener pack with screws, drill, tap and hex wrench.
Fits Boats: 25 ft to 27 ft.

Installation Manual
Note:
To avoid undue stress on the boom fitting, it's recommended
that booms be fixed in the upright position. If the boom can roll about
its' central axis, please contact the factory before installation.
Recommended Installation Tools:
Phillips Screwdriver;
Fine Tooth Hacksaw; Center Punch; Rule; Variable Speed Reversible Drill
and Blue Locktite.
1. Setup Boom Height:
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 K0800 is correct.
The min. length is 35 in (89 cm) pin to pin and the max. weight it can
support is approximately 25 lb (11.3 kg) at the outboard end of the boom
with the main sail flaked as stored.
2. Position Boomkicker:
The Boomkicker works by flexing
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 bracket 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 #7 drill and the 1/4-20 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 clamp plates for
each end 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. It is also recommended to check
tighten the rod clamp screws once a season.
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 pin 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.
