Understanding Design and Operations of Beneteau Oceanis 38 and Oceanis 40 CC
Anchors are essential in ship movement, assisting ships securely docking at ports and on the high seas. A heavyweight known as the anchor head generates the resistive forces to keep a whole vessel (weighing a few hundred tons) in place. However, have you ever considered how a significant item of such size gets lowered and raised from the sea floor? The windlass anchor is a mechanical device used for this purpose.
A windlass is any pulley or mechanical device that transfers heavyweights in either a vertical or horizontal orientation. It was designed by the ancient Greek scientist Archimedes. It was used for various purposes, including drawing water from wells and assisting in lifting heavy construction equipment.
Heavy anchors are necessary to stop larger ships have been forced into duty as technological improvements have placed more demands on the shipping and freight transport industries. As a result, innovative anchor windlass systems have been employed to operate the anchor and accompanying gear effectively. This post will look at a windlass anchor and how it works.
A Windlass’s Basic Design
A windlass is any device that uses a pulley system to move big weights. A belt or crankshaft drives a barrel wrapped around a chain or cable. This circular shaft allows it to hoist huge weights without using the energy required to move them conventionally. The crank, which is linked to the barrel and may spin about a central axis, can be handled manually (as in the case of extracting water from wells) or by the motor (as in substantial construction cranes).
The idea behind a pulley design is that huge weights may be lifted by dispersing the load across numerous cables rather than a single chain. Thus, a significantly more considerable weight may be successfully hoisted with little effort.
Such systems have the drawback of applying excessive pressure to the wire or chain used to convey the weight. Therefore, appropriate measures must be implemented to prevent the cable from breaking under stress if the machine is stopped in the middle of its operation.
When subjected to tension loads, most materials are susceptible to fatigue or stress-related failure. As a result, to ensure that the anchor head is withdrawn from the anchor rode when the operation is stopped, specialized mechanisms must be used with an anchor windlass that must elevate almost a ton of weight. More information about this will be provided in the sections that follow.

Beneteau Oceanis 38
At the most recent Annapolis boat show, everyone was raving about Beneteau’s new multi-personality performance cruiser, the interior of which can be modified so drastically that it defies the definition of a production boat. However, this model does not just grow from earlier thoughts; instead, it leaps off the drawing board and pushes you to conceive its ideal use.
The Beneteau Oceanis 38, like most of Beneteau’s modern designs, features angular solid lines with a nearly plumb bow and a slightly reverse transom. The low cabintop creates a pleasing appearance while concealing the capacity and headroom.
The dual rudders enable the hull to grip the water independent of heel angle despite the beam being carried well aft to a large stern. A substantial chine running from well forward to well aft also aids in keeping the Oceanis 38 sailing up to five degrees’ flatter than it would otherwise. That makes a difference for anyone who has had to brace himself in the wind.
To boost rigidity, the hull is moulded in polyester, with a hull liner glued in at the start of the construction process. To increase strength and minimize weight, the deck is injection moulded with a Saerfoam core, then fastened to the hull with adhesives and screws and “trimmed” with a 1-inch toerail. The keel is made of cast iron. Stainless steel is used for rudder stocks.
