Q

On which type davit does the davit head stay at the same height?

🔍 Key Concepts

• How each type of davit moves the lifeboat outboard • Whether the davit arm pivots in an arc (up and down) or slides/rolls sideways at a constant level • The meaning of the head of the davit staying at the same vertical height during operation

💭 Think About

• Visualize the motion of each davit type: does the davit head swing in a circle (changing height) or travel mostly horizontally (same height)? • Ask yourself which design is common on modern ships for rapid launching under gravity, where the boat travels down a track at a fixed level until it is lowered by falls. • Think about older-style davits that required more manual effort and swung the boat out in an arc—would their head height stay the same or change?

✅ Before You Answer

• For each davit type, decide: does its arm rotate about a fixed pivot, causing an arc (change in height), or does it move along a track/guide (nearly constant height)? • Recall which davit type is standard on many SOLAS lifeboats for quick launching, and consider its travel path. • Eliminate any option where the davit clearly swings like a crane boom, since that would change the davit head height.
