  Windlass - Wikipedia, the free encyclopedia
Typically, a windlass consists of a horizontal cylinder (barrel), which is rotated by the turn of a crank or belt.
A winch is affixed to one or both ends, and a cable or rope is wound around the winch, raising a weight attached to the opposite end.
Windlasses are used in sailing, often to raise anchor on smaller vessels, wherever space is at a premium and a capstan would be too large.

 Hedderwick, "A Treatise on Marine Architecture", 1830.
The principal piece of the windlass, marked D in all the figures, is an octagon, whose diameter at the center and at the inside of the range-bitt C, is represented by Figs.
Also, by boring the windlass right through from end to end, it prevents any rot from taking place in the centre of the piece by taking out the heart, which in large pieces of timber is generally soft and the first to decay, and communicates the rot to the other parts.
Having already pointed out the form and position of the hoopes and bushes, and supposing the windlass made on the ground, and the pawl-bitt placed, the windlass-bitts should be in thickness 1-3d of the diameter of the windlass, and in breadth not less than a whole diameter of the same.

 Windlass
Windlass (ARS(D)-4)—originally conceived as LSM-552—was laid down on 27 August 1945 at Houston, Tex., by Brown's Shipbuilding Co., Inc.; launched on 7 December 1945; and commissioned on 9 April 1946 in Houston at the Tennessee Coal and Iron Docks, Lt.
Windlass received a summons to assist in refloating the grounded destroyer Basilone (DDE-824) off Fort Story, Va. Rough weather hampered the operations which were begun on 5 January 1956, and Seneca (ATF-91) also ran aground during the attempt to pull Basilone free.
Windlass subsequently recovered the wrecks of airplanes, salvaged small landing craft that had sunk during amphibious maneuvers, and participated in other classified projects in locales that ranged from Argentia, Newfoundland, to Chesapeake Bay; from Guantanamo to Assateague Island, Va.; and from San Salvador to Nova Scotia.

 BoatUS BoatTECH Guides: Anchor Windlasses
Lever-type windlasses are generally single speed, and vertical models, like sheet winches, have two speeds: a fast, low-power gear for light loads, and a slower speed with higher power for when the going gets tougher.
Windlasses weigh a lot and handle high loads; you may need to reinforce your deck and spread the load with marine plywood or an aluminum or stainless plate.
Although your windlass is rated at three times the weight of your anchor and chain, the slop factor takes into account strong wind, current, and recalcitrant anchors firmly dug in.

 Motor Boating Magazine - Boatkeeper - Installing or Replacing a Windlass
Windlasses are a back-saving luxury for some boaters and an absolute necessity for others, but installing or replacing one must be done with care to ensure that the results are worth your investment in time and money.
Essentially, windlasses vary by the type of rode they are designed to handle and where they direct the rode as it is hauled up.
The gypsy on a chain-only windlass has no groove for rope and is usually found on larger vessels that require the strength and reliability of an all-chain rode.

 Choosing A Windlass - Windlasses
Using the windlass to haul the boat to the anchor is not recommended and will result in damage to the windlass and motor.
Windlasses are not designed to hold high loads while a boat is at anchor.
When the windlass is not is use and the boat is at anchor, the anchor rode should be secured using a chain stopper or attached to a load bearing point such as a cleat.

 Windlass (ARSD-4)
Windlass (ARS(D)-4) (originally conceived as LSM-552) was laid down on 27 August 1945 at Houston, Tex., by Brown's Shipbuilding Co., Inc., launched on 7 December 1945, and commissioned on 9 April 1946 in Houston at the Tennessee Coal and Iron Docks, Lt. Comdr.
She investigated the wreck of SS Chile off Cape Henry, ascertaining whether or not the wreck was of sufficient danger to be a hazard to navigation, recovered practice mines, raised an LCVP off Wolf Trap Light; and planted moorings at Bermuda.
Other operations performed by Windlass during 1951 included; removing channel obstructions, raising an LCM and a small boat, refloating the grounded PC-572 off Cedar Point, removing the obstruction which had fouled a propeller of Gearing (DD-710), righting a target sled, conducting diving school, and mooring the hulk of the former YC-818 in the Potomac River.

 Windlass information for sailing yachts and boats or boat-for-sale
With the combination of high current loads and cable length it is subject to voltage drop problems, and anchor windlass performance and therefore lifting capability is reduced by the installation of incorrectly sized and rated cables.
Windlasses do not have a constant load during anchor recovery, but have a varying load according to the various phases of anchor recovery.
A windlass is not designed to take the entire load when riding to anchor, especially in large swells or heavy conditions, and you can damage the gearbox with heavy shock loads.

 The Windlass Effect -September '03
Windlass (pronounced WIND-less, as in how you feel after the first mile if you go out too fast) usually refers to some kind of machine that lifts a load by pulling on a line.
When windlass is an "effect" rather than heavy equipment, the machine is your foot, the line is your plantar fascia, and the load is you.
The flexing joints act as a windlass, pulling on the plantar fascia, which accelerates the lifting of the heel, and forces the arch to rise up into, yes, a rigid lever.

 Fantasia 35 Windlass Installation
The criteria used to select the type of electric windlass was based on the desire to have the windlass mounted inside the forward locker which is where the existing Simpson Lawrence Sea Tiger 555 was mounted, to have a simplified installation, to have trouble free service and to keep the total project costs down.
As it was not desirable to have windlass mounted on the deck, the solution to this problem was to elevate the windlass to the highest point internal to the windlass locker.
The windlass had four stainless threaded mounting studs that had to be removed and replaced with longer stainless all thread.

 Podiatry Arena - Windlass Mechanism Enhancing Running Shoes
It could be hypothetically assumed that if the windlass mechanism is functioning efficiently then there would be a more rapid movement of forces from the heel to the forefoot, greater forces under the medial column (due to first metatarsal plantarflexion as the windlass establishes) and a relatively lower forces under the lateral column.
Based on this, it could then be assumed that if force to establish the windlass is high and a windlass enhancing shoe has the effect of lowering this force, then subject specific differences should be seen between the windlass and non-windlass shoe and this should be correlated to the force to dorsiflex the hallux.
This study has shown that there are some systematic functional differences between windlass enhancing running shoes and the nearest non-windlass enhancing running shoe and some of the subject specific response to these shoes can be explained by the force needed to dorsiflex the hallux (establish the windlass mechanism).
