A davit ( dt. [ ˈDeːvɪt ], engl. [ ˈDævɪt, ˈdeɪ̯vɪt ]) is a launching device for boats - especially the lifeboats - of a ship . Conventional davit constructions of larger ships consisted of swiveling cranes (swiveling davits) that were attached to the side near the ship's side. On smaller ships, davits protruding at or over the stern were also used. The davits, made of wood or iron, could partly also be used to launch and lower heavy anchorsbe used. Nowadays only steel davits are used.
Common contemporary construction types include:
- The gravity davit is the usual variant that is also prescribed for lifeboats. It does not need any energy to lower the boat, i.e. H. this can be occupied by people hanging in the davit, whereby only one of them has to release the rope brake to lower the boat into the water.
- Freefall davits are not davits in the traditional sense. When fully occupied, the boat falls freely from its pallet into the water. The davit is only used for hauling in and stowing the boat.
- In the Caley davit , the boat hangs rigidly on an extendable crane arm (runner) by means of a harness, is set down with this on the water surface and automatically notched.
