Choosing a davit is a critical decision that may determine the fate of your lifeboat. With many types of davits on the market today, you need to know the essential features and specifications to make an informed purchase. This article will explain everything you need to know about lifeboat davits and what to look for when buying a davit.
A lifeboat davit is a device used to launch a lifeboat from a ship or another structure. The primary purpose of the davit is to lift, lower and hold the boat securely in place during launch. The davit has been around since early on in maritime history, and they have also been used in other applications such as an improvised crane, a log boom, or even a diving platform.
There are several different types of lifeboat davits, each serving a specific purpose. Here is a short overview of the most common types:
Gravity davit is the most common type of davit, and it is also the simplest. It consists of a set of wheelsor trolley tracks, which are used to move the boat along a rail to allow access to the lifeboat underdeck or in other areas with limited room for maneuvering.
Single pivot davit is also referred to as a vertical luffing davit. This type of davit is used when the objects to be worked upon are placed at heights that cannot be reached using a normal gravity davit. This type requires a person to turn the head of the davit to lower the lifeboat, which makes it very slow and labor-intensive.
Snap davit is a point-to-point type of vertical liferaft launch and retrieval system. It consists of large wheels, which allow the boat to be moved along a set of tracks, which can be turned by a person using a long pole.
A sling davit is a small davit attached to a ship's deck railing. It is similar to the pull-on davit and can be used with boats that are designed for launching only. They are mainly used in fishing vessels, but they are also found aboard lifeboats.
Fixed davits attach to structures such as the railingand can be used for launching or retrieving lifeboats. Fixed davits consist of a set of heavy steel hooks mounted on a rail and attached to tracks thatallow the boat to be moved along the rails from one side of the structure to another.
Lifeboat davits are crucial equipment for any vessel carrying a lifeboat. When choosing a davit, several factors need to be considered. They include:
One factor that determines which type of lifeboat davit you should use is the purpose. For example, some lifeboats are designed for launching only, so you may prefer to use a gravity davit, while others can also be operated from a power source.
The weight of the davit is another important factor that needs to be considered when buying a lifeboat davit. Heavy-duty davits are usually more rigid and will not vibrate and rattle as much, but they arealso more costly. Therefore it is your decision how much you are willing to spend on a particular davit.
You should make sure to buy a product that can be easily obtained. You also need to know where to get parts if something breaks or becomes obsolete. If you plan on using the davit with your boat for many years, you will likely have to replace parts over time. That's why you need to ensure you have a good selection of available parts and accessories.
Another important factor to consider when buying a lifeboat davit is the lifeboat type. The weight of your lifeboat and its design can influence which type of davit you should use.
Different types of davits can be used for launching different types of lifeboats. A single pivot davit is most appropriate for a lighter lifeboat with a low center of gravity. At the same time, a pull-on davitis most suitable for launching lifeboats that are heavier than one ton. Fixed davits can be used with any type of liferaft; they will work with the same kind of lifeboat regardless of its weight or type. Gravity davits can be used with all types of lifeboats, and they are best suited for launching orretrieving small lifeboats with a limited number of people on board.
When selecting, it is important to consider the features of the particular lifeboat davit you are interested in, the budget, and your requirements. Determining your needs and choosing the best davit for you is often important, especially if davits are made from different materials.
