Q

After the boat is at the top of the davit heads, the davit arms begin moving up the tracks and are stopped by the __________.

🔍 Key Concepts

• Gravity davit operation sequence: how the boat moves from the embarkation position to the outboard position • The purpose of a limit switch versus a mechanical stop or bar • Who/what physically stops motion in an automatic power-operated davit system

💭 Think About

• When the davit arms reach the top of the tracks, is motion normally stopped by a person or by an automatic device? • Which of the choices is specifically designed to stop travel at a preset point to prevent over‑travel or damage? • Think about what part would be used as a safety feature in an electrically powered hoisting system.

✅ Before You Answer

• Identify which option is an automatic control or safety device rather than a human or a general mechanical part • Ask: which item is normally installed to cut power or stop movement when a moving part reaches the end of its safe travel? • Confirm which component is commonly associated with electrical or powered hoists to prevent over‑hoisting.
