When hoisting a boat on gravity type davits using an electric motor driven winch, the davit arms should be brought up to which position?

🔍 Key Concepts

• Operation of gravity davits and how they are normally stopped in the raised position • Purpose of hand cranking at the end of hoisting and what risk it avoids • Function of mechanical stops vs. electrical limit switches in winch systems

💭 Think About

• Ask yourself: Which stopping point is designed as a positive mechanical stop that does not depend on electricity or a switch working correctly? • Why would the procedure call for hand cranking only in the final part of the hoist, instead of using full power all the way up? • Which option best prevents over‑hoisting and damage if something in the electrical system fails?

✅ Before You Answer

• Identify which choice refers to a built‑in mechanical stop on the davit, not just a switch or a deck level • Consider which method would be safest if the limit switch failed or was out of adjustment • Verify which option allows the winch to do most of the work, but still uses manual control for precise final positioning

When hoisting a boat on gravity type davits using an electric motor driven winch, the davit arms should be brought up to which position?

Until just before they make contact with the limit switch, and then hand cranked to their final position

To the embarkation deck, and then hand cranked to their final position

To the bar stop, and then hand cranked to their final position

To their final position with the winch operating at slow speed
