w/fittings - Sailboats 14 to 16 ft.

* At Maximum Pin to Pin Length.
1 Maximum stroke at initial Pin to Pin.
2 Maximum stroke at min. Pin to Pin.
** Stroke is travel when flexed. 1 in of stroke equates to approximately 7 in at the aft end of the boom.

The Boomkicker model K0312 works basically the same as the larger models, but instead of attaching directly to the boom, a webbing sling, suspended between the two spring rods, supports the boom.

Designed for smaller daysailers, these Boomkickers are easy to install with no drilling or tapping required. All parts fit in the luff groove of the mast. For trailering, the design makes rigging and de-rigging a snap, simply remove the boom and fold the Boomkicker up against the mast for storage.

The sling, because it does not attach directly to the boom, allows these models to work with the simplest of goosenecks. Even if the boom just slides onto a pin at the gooseneck, or can roll, the Boomkicker can not push the boom back or restrict it from rolling around its central axis to follow the sail.

Boomkicker K0312: Includes mast fitting with round luff groove slide, Boomkicker with 5/16 in diameter spring rods, webbing sling to support the boom, control line from sling to mast and eyestrap with round luff groove slide.

Fits Boats: 14 ft to 16 ft.

Note: Uses webbing sling at boom instead of track fitting.

_x000D_ _x000D_ 1. General:_x000D_ _x000D_ The Model K0312 Boomkicker is designed for _x000D_ sailboats under 17 ft (5 m) who's boom, with sail, weighs under 16 lb (6.8 kg). _x000D_ To the right is a sketch of the Model K0312. The Boomkicker comes fully _x000D_ assembled. Two fiberglass rods provide the force to support the boom. _x000D_ The boom sits in the sling between the rods. The sling is held by the _x000D_ line to the gooseneck stop and controls the initial height of the boom. _x000D_ The mast fitting and stop use slides in the luff groove to avoid drilling. _x000D_ As shown, the Boomkicker works by flexing upward and when straight, it _x000D_ is at the top of its travel. The Boomkicker does not restrict the boom _x000D_ from rising higher.

_x000D_ _x000D_ 2. Installing Mast Bracket and Gooseneck Stop:_x000D_ _x000D_ The Boomkicker _x000D_ works best if the boom/gooseneck is fixed in one spot on the mast. If _x000D_ the boom/gooseneck can slide, then in the normal sailing position with _x000D_ the sail up, place a mark on the mast, indicating the lowest point of _x000D_ the gooseneck inside the luff groove. Then remove. Using the sail opening _x000D_ in the mast, slide the assembled base with bracket and slide to the vang _x000D_ bail, do not tighten. Next slide the top of the gooseneck stop to the _x000D_ mark and tighten. Reposition the boom against the gooseneck stop. If the _x000D_ boom/gooseneck is fixed to the mast, the slides can be detached, slid _x000D_ past the gooseneck and reassembled in position.

_x000D_ _x000D_ 3. Final Positioning:_x000D_ _x000D_ Using the main halyard, li ft the _x000D_ a ft end of the boom 6 in - 8 in (15 cm - 20 cm) above horizontal or _x000D_ the normal sailing level. Orient the Boomkicker so the two screw heads _x000D_ on the base are facing downward or a ft, and the sling loop for the line _x000D_ is forward. If the Boomkicker fits in the area above the vang, hold the _x000D_ sling around the underside of the boom and adjust the mast fitting location _x000D_ to make an angle between 40º and 45º with the boom. The sling _x000D_ line should be loose and is adjusted later. If the angle is much lower _x000D_ than 40º, then as the spring rods flex, they lose ability to hold _x000D_ the boom. Tighten the bracket in position. If the Boomkicker is too long _x000D_ or the angle too low, it can be cut down. Shorten the bottom of the rods _x000D_ (loosen two small screws in base to pull the rods out) equal lengths of _x000D_ no more than 5 in (13 cm). A fine tooth hacksaw works best and frayed _x000D_ ends can be avoided by prewrapping a layer of tape around the rod at the _x000D_ cut.

_x000D_ _x000D_ 4. Final Adjustments:_x000D_ _x000D_ With the boom/gooseneck held against _x000D_ the stop, adjust the line between the sling and gooseneck stop so the _x000D_ sling supports the boom. Since some initial stretch can be expected under _x000D_ load, slightly overtighten. Disconnect the halyard from the boom and press _x000D_ the boom down to flex the Boomkicker. It should flex freely upward and _x000D_ have enough support for the boom and mainsail without sagging.
