To choose the right windlass, it's important to consider several parameters as well as the product's main technical features. The choice of windlass type should be based on the length of the boat, the power of the motor (in watts) and the maximum pulling force required. The biggest problem will undoubtedly be the space available for positioning the windlass.
1 - Windlass type: vertical or horizontal
Windlasses are referred to as vertical or horizontal, depending on the axis of rotation of the sprocket. Both vertical and horizontal windlasses have advantages and disadvantages, depending on their design and use.
The vertical windlass generally offers better pulling efficiency, as the chain or rope makes a complete turn around the spool, ensuring a good hold. This type of windlass also takes up less deck space, as the motor is mounted below deck, freeing up deck space and preventing ropes from getting caught in it. Finally, from an aesthetic point of view, the compact design and below-deck installation make the vertical windlass less visible, contributing to a cleaner, tidier appearance on deck.
Conversely, fitting a vertical windlass can be more complex and costly, requiring deck drilling and adequate sealing to protect the motor below deck. Access to the motor for maintenance or repairs can be more difficult, often requiring work in confined spaces below deck or in the anchor locker.
In comparison, the horizontal windlass is easier to install, as all the equipment is mounted on deck, simplifying the process and reducing the need for drilling and sealing. Access to the motor and components is easier, as everything is deck-mounted, facilitating maintenance and repairs. On the other hand, they take up more deck space, which can be a disadvantage on boats where space is limited. And having the windlass and its components exposed on deck can be less aesthetically pleasing, presenting a risk of snagging for sheets, or even tripping the crew.
But in the final analysis, the choice of model depends above all on the space available on the boat to accommodate the motor and sprocket, and the possibility of securing the windlass in a very solid point on the deck.
2 - Traction force and electric motor power
Windlass motor power must match boat size and intended operating conditions. The supply voltage (12V or 24V for pleasure boats) must be compatible with the boat's electrical system. Adequate power is necessary to ensure that the windlass can operate efficiently without overheating or tripping.
The windlass must be able to support the weight of the anchor and chain. The pulling capacity of the windlass, usually expressed in kilograms or pounds, must be sufficient to lift the anchor from the seabed. We recommend choosing a windlass with a lifting capacity greater than the combined weight of the anchor and chain to provide a safety margin, for example when the anchor is loaded with silt or algae.
3 - Sprocket size and compatibility with cablot
It's crucial to ensure that the windlass is compatible with the type and size of chain or cable being used. Some windlasses are designed to work only with chain, while others mix chain and cable. Check the windlass specifications to make sure it can handle the diameter of chain or rope you're using. Some windlasses even have a dedicated cable headstock, in addition to the chain sprocket.
