Boomkicker Offers Safety For The Mainsail

The boomkicker typically runs from the base of the mast to a point about a third of the way out the boom. Due to the great force necessary to change the height of the boom while a boat is under sail, the vang usually includes some sort of a pulley system. Hydraulic piston vangs, are used on larger sailboats and controlled by manual or electric hydraulic pumps.

This pulley system is either hydraulic or manual. Due to the pressure which the mainsail is under when sailing, without, it would be impossible to alter the height of the mainsail.

<<>> The vang runs usually from the base of the mast to one third the length along the boom. The control provided, ensures optimum performance from the mainsail at all times. From hoists, reefing and flaking the importance of this gadget is high.

larger vessels have hydraulic vangs. The power coming through pistons which are controlled by electric hydraulic pumps. Manual systems harness the boom by a pulley ratio. The ratio depends on the size of the sailboat. A normal ratio might be 4:1. Depending on the activity at one particular time, the crew is powering, or depowering the vang.

When you are about to round a mark, then de powering is in order. This means the mainsail will move unheeded as the tiller or wheel moves to round the mark. When the maneuverer is complete the boom kicker is powered up, inhibiting the boom and mailsail.
