SART |
 |
 |
SART stands for Search And Rescue Transponder. A SART is meant to help rescuers locate you in an emergency situation. When activated a vessel (or rescue helicopter) that is equipped with a 9Ghz bandwidth radar will be able to home on your SART device. The SART will show on the radar as a series of 12 dots. When you get closer to the SART the dots will become bigger and bigger circular lines until they are fully closed concentric circles. By this time you are no further than 1 mile away from the SART. When spotting a SART on your radar you should check with the nearest coast station if they know about an emergency situation and offer assistance when required. When, in an emergency situation you have to leave your vessel for a life raft you should always take your SART with you. Mount the SART as high as possible in your life raft for it to be "visible" as far as possible.

Boom Vang |
|
|
|
A boom vang or kicking strap (kicker) allows vertical adjustment of the boom. It is an important tool in shaping the main sail. The vang typically runs from the base of the mast to a point about a third of the way out the boom. Tensioning the vang tightens the leech of the sail, flattens the sail and bends the mast. By controlling leech tension, the boom vang is one of the three methods of controlling sail twist. The other two are the main sheet and the traveler. Cruising sailors use the vang to keep the boom from rising downwind. While under sail, the opposite force to the vang is supplied by the sail itself. When the sail is reefed, a topping lift supplies the upward force on the boom. Some line vang systems incorporate a piston to provide the topping lift force and to damp oscillations. |

I, J, P, E: what do they stand for and what knowledge do they give you ?  "I" is measured along the front of mast from the genoa halyard to the main deck. The main deck is where the deck would be if there were no deckhouse. "J" is the base of the foretriangle measured along the deck from the headstay pin to the front of the mast. "P" is the luff length of the mainsail, measured along the aft face of the mast from the top of the boom to the highest point that the mainsail can be hoisted or black band."E" is the foot length of the mainsail, measured along the boom from the aft face of the mast to the outermost point on the boom to which the main can be pulled or to the black band. When you know those values you can use the following formulas to calculate approximate areas for: - Mainsail = (P x E) / 2 (add 10% for racing mains)
- 135% Genoa = (( J x I ) / 2) x 1.44
- 100% Jib = ( I x J ) / 2
- Racing Spinnaker = 1.8 x J x I
- Cruising Spinnaker = 1.65 x J x I

EPIRB |
|
|
|
EPIRB stands for Emergency Position Indicating Radio Beacon. An EPIRB is meant to help rescuers locate you in an emergency situation. When activated an EPIRB starts sending a unique serial number via a satellite radio. The signal frequency used (406 Mhz) has been designated internationally for distress use only. The signal allows the satellite to locate the EPIRB to less then 5 km accurate anywhere in the world. However, this requires multiple satellite orbits and could take several hours. Some EPIRB's are therefore equipped with a GPS and send their exact location with the emergency signal. All EPIRB's need to be registered with the authorities so rescue services know full details about the vessel and owner immediately. |
