What is the line which raises the boom to a desired height?
The topping lift (more rarely known as an uphaul) is a line which applies upward force on a boom on a sailboat.
What is a boom line?
Lines on the boom. The control lines (ropes) on the boom act in conjunction with the halyard and leech line to ensure that the sail is trimmed most effectively. Two primary sail control lines are attached to every boom: The outhaul runs from the clew of the sail to the free end of the boom.
What is the rope that holds the boom?
The boom vang holds the boom down when beating to wind. On down wind legs the boom vang can be loosened to provide more shape to the sail. The cunningham pulls the sail down tight and is used also when reefing. The outhaul line is attached to the clew to pull the sail out along the boom.
What is the best line for a topping lift?
There are no high demanding requirements for a topping lift. We recommend a durable double braided polyester rope in this case.
How do you make a boom topping lift?
The classic way to make a topping lift is with a halyard similar to the mainsail halyard. But instead of attaching the shackle to the head of the mainsail, you attach it to the aft end of the boom. The working end of the line can be cleated at the mast or led aft to the cockpit.
Why is it called a boom?
The word "boom" is the Dutch word for tree. German is similar: "baum." Remember "O Tannenbaum," a Christmas carol of German origin? From these roots, we get the word "beam" as in a long wooden timber, and of course, a part of a sailboat, the "boom," that holds the foot of the sail and was traditionally made of wood.
What is a boom in rigging?
A crane boom is the long, telescopic arm used to lift and transport heavy objects. The boom is normally constructed of steel and can be extended or retracted to change the crane's reach. The boom is coupled to the turntable of the crane, enabling the operator to rotate and position the boom above the load.
What is the rope for raising a sail?
In sailing, a halyard or halliard is a line (rope) that is used to hoist a ladder, sail, flag or yard.
What is the anchoring rope called?

What is a bull rope?
any of various ropes for holding objects to prevent them from rubbing against or striking other objects.
What is the difference between boom vang and topping lift?
The topping lift holds up the boom when the sail is down, and should be released once the mainsail is up so the sail can assume it's proper shape. Conversely the vang pulls the boom down when the sail is set, primarily when going when downwind to counter the booms tendency to rise.
What is a Vang on a sailboat?
The vang allows vertical adjustment of the boom, and is an extremely important tool to shape the main for speed. Tension the vang to tighten the leech, flatten the sail and bend the mast. Cruisers use the vang to keep the boom from rising when sailing downwind and abraiding the main.
What type of lift is a boom lift?
A boom lift, also known as a cherry picker, is a type of aerial lift. Boom lifts work by connecting a hydraulic arm to a platform or bucket.
Why use a boom lift?
Better Maneuverability – A boom lift is the better choice if you need to maneuver around objects. The long arms can be angled in many directions to access hard-to-reach places. Higher Lift Heights – Boom lifts usually extend much higher than scissor lifts.
Can you tip a boom lift?
Boom lifts are engineered to be very stable, but while working at heights they can become top-heavy, increasing the risk of tipping. It's important to remember that these machines are not impossible to tip despite their incredible design.
What are the legs on cranes called?
Outriggers (sometimes called Stabilizers) are retractable hydraulic `legs' that extend, like a spider's legs, away from the truck before they make contact with the ground. Hydraulic outriggers commonly come in two shapes.
Why is it called a knuckle boom?

What's the difference between boom and jib?
Crane jibs are secondary structures that can be attached to the end of a boom as an extension. Jibs help to increase the boom length of a mobile crane, but they reduce lift capacity as they extend the reach.
What is a luffing jib?
A luffing-jib crane is characterized by the ability to raise and lower its jib, which allows it to reduce the turning radius. The Luffing Series includes Comansa's entire range of luffing-jib tower cranes.
What is the terminology of rigging?

What line do you use for halyards?
Use a blended braid Vectran® or Spectra® line for the halyards, jib sheets, and guys. Avoid using polyester for these high-load applications so that you don't have to get extra-large diameters. Polyester can be used in control lines and other lower load lines.
What is a governor rope?
Governor ropes transmit the speed of the elevator to the overspeed governor and its tripping pulse in the event of overspeed to the safety gear.
What are the ropes in a ship rigging called?
The ropes on a boat are called lines. There are various types of lines, including mooring lines, dock lines, and tow lines. Each type of line has a specific purpose. For example, mooring lines are used to secure the boat to a dock or another vessel.
