What are spars on a sailboat?

What are spars on a sailboat?
A spar is a pole of wood, metal or lightweight materials such as carbon fibre used in the rigging of a sailing vessel to carry or support its sail. These include yards, booms, and masts, which serve both to deploy sail and resist compressive and bending forces, as well as the bowsprit and spinnaker pole.
What is a spreader rig?
The spreader boom rig is a general purpose, boat fishing rig. With two hooks hard on the seabed it is particularly effective for flatfish, gurnards etc.
What are sailboat spreaders made of?
Spreaders are metal (usually aluminum), wooden (usually spruce), or composite (usually carbon fiber) and are attached to the mast on spreader bases.
What are shrouds on a sailboat?
On a sailing boat, the shrouds are pieces of standing rigging which hold the mast up from side to side. There is frequently more than one shroud on each side of the boat. Shrouds are attached symmetrically on both the port and starboard sides.
Why is it called a boom on a sailboat?
Why is it called the “Boom?” The origins of the term “boom” in the sailing world are unclear. Some people speculate that the word came from the early use of Lateen rigs in the middle east, while others attribute the term to colloquial sailor-talk. Nonetheless, “boom” is a fitting name.
What is a boom 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.
Why do sailboats have spreaders?
A spreader is a spar on a sailboat used to deflect the shrouds to allow them to better support the mast. The purpose of the spreaders is to control, by either limiting, or inducing, bend into the spar so that when the windward shroud is loaded the mast achieves the desired bend characteristics.
How do you change a sailboat spreader?
Tie off halyards and have a spotter to maintain them. Disconnect the shroud from the chainplate on the deck. Climb the mast, remove the old spreader and install the new spreader. Reconnect the shroud to the chainplate and restore the halyards to their original place.
How tight should sailboat shrouds be?
They should be tight enough that when you push or pull on them, they don’t want to jiggle around too much. If they feel loose or floppy, you need to tighten them further. Once the cap shrouds are set, the rest of the shrouds simply follow in sequential order with none of them being tighter than the cap shrouds.
How long does sailboat rigging last?
Question – When should I replace my standing rigging? From the Rigger – According to industry standards, the anticipated lifespan for stainless steel rigging is 10-12 years for wire and 15-20 years for rod.
What is the purpose of a spreader on a sailboat?
Unsourced material may be challenged and removed. A spreader is a spar on a sailboat used to deflect the shrouds to allow them to better support the mast. The spreader or spreaders serve much the same purpose as the crosstrees and tops in a traditional sailing vessel.
Why do you need a spreader bar on a crane?
Why Use a Spreader Bar? A spreader bar is a type of below-the-hook lifting device used to aid crane operators in picking up large and sometimes heavy loads. The idea behind a spreader bar is to simply distribute the load of a lift across more than one point, increasing stability and decreasing the loads applied during hoisting.
How are spreaders used to support a mast?
Spreaders are struts attached to the sides of a mast to hold the shrouds away from the mast and increase the angle at which they meet the mast. The greater the angle between shroud and mast, the lower the shroud tension required to provide lateral support and, therefore, the less the compression on the mast.
What’s the best way to use a spreader bar?
There are several styles and options of below-the-hook lifting devices that can be used to accomplish this. The styles include: the spreader bar, the spreader beam, and using multiple spreader bars stacked together. These options are discussed below.

How are spreaders used on a mast rig?
Spreaders Spreaders are used on most Rigs to improve Mast support by increasing Upper (and Intermediate) Shroud angles. Spreaders are specific to particular Spreader Bases (or Spreader Bars), which, in turn are specific to individual Mast Sections.
