    Boomkicker for boats 16' to 19'

    The Boomkicker model K0400 works basically the same as the larger models by flexing as show below, 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.

    When installed, the Boomkicker is straight and the boom should be positioned above the usual sailing height. As the mainsheet or vang is tensioned, the Boomkicker flexes smoothly from straight to flexed. The force stays relatively constant as the Boomkicker continues to flex, which helps keep the vang efficient. Each model now includes only two rods of a specified diameter and force. If after installation the force is more or less then desired, optional rods are available either as exchange or for purchase. The more forceful the rods, the more support for the boom but the harder it will be to pull on the vang. In general only about 10lbs should be needed to pull the end of the boom down by hand. At their initial length, the rods provide as much as 6 feet of travel at the end of the boom depending on set up.. If needed the spring rods can also be shortened within limits to fit above the vang with some loss of range.

    Both the gooseneck eyestrap for the line and the mast fitting have standard 3/8" diameter slides to fit in the luff groove and avoid drilling. 1/2" diameter is also available. The length of the line positions the sling along the boom and determines the initial boom height. The gooseneck eyestrap also serves as a stop if the gooseneck slides in the luff groove.

    Where both the K0312 and K0400 models have webbing slings, the model 400 mast end is all aluminum, basically the same one used on the model 500. Initially both the models K0500 and K0400 share the same rod diameter, and force, so the only difference or choice is whether you prefer the sling attachment or aluminum track fitting. However the K0500 offers both larger diameter (more force) and smaller diameter (less force) rods as an option, where the K0400 only offers a smaller diameter.
