Types of Davit System for Boat and How They Work
Davit manufacturers came up with many types of davits depending on their functions. Davits can also be classified based on their features.
Check out the different types of boat davits below and their brief description.
1. Swing-up/Snap Davit
A snap davit system is considered the most basic. It is a popular choice for small boats that have a swim platform.
It works by attaching the connecting hardware to the dinghy and the swim platform. The dinghy will be pulled up vertically after securing the dinghy fittings into the swim platform.
2. Single Arm Davit
This type of davit is popularly used for launching and storing rescue boats or rafts. It features a single arm that is responsible for hoisting and lowering the cargo.
This crane-like davit can be manual or electric.
3. Traveler Davit
This type of davit has a more advanced mechanism for lifting and lowering boats or dinghies. It is an automatic davit system.
The traveler davit features two cables that help control the hoisting and lowering of the item.
4. Gravity Davit
A gravity davit is a hinged type of davit that lowers items using gravity fall instead of cables. This davit system can be controlled using a remote or the brake handle of the winch.
5. Sling Davit
Sling davits operate using a sling that the boat rests in. They are commonly used on smaller vessels and are considered the most cost-effective davit system on the market.
The sling davit is installed behind the boat, floating, and waiting for a dinghy to be lifted.
6. Pull-on Davit
A pull-on davit works similarly to how the traveler davit works. The main difference is that this davit uses a cable release system that pulls or pushes the object being hoisted.
7. Hydraulic Gravity Davit
This davit system uses hydraulics to hoist and lower lifeboats. This system is a specialized davit intended for shipboard launching and recovering a lifeboat.
The mechanical system of this davit allows the safe launching of a lifeboat using gravity and hydraulics.
8. Crane Davit
You should be familiar with what a crane looks like. A crane davit features a folding crane that raises and lowers lifeboats. This is a common davit on a ship because it requires bigger space.
