🔍 Key Concepts

• Compare how gravity davits move along tracks using the boat’s weight versus how radial or quadrantal davits swing or rotate about a fixed point. • Look closely at the inclined track and cradle shown under the lifeboat in the illustration and how the davit arms and boat travel from the stowed to the launched position. • Recall that round‑bar davits and classic radial davits are usually simple swinging arms without large track structures under the boat.

💭 Think About

• From the illustration, does the lifeboat mainly slide down an inclined track under its own weight, or does it simply swing like a door on a single pivot? • Do you see any curved quadrant-shaped track that the davit arms roll around, or is it more of a straight/sloped track arrangement? • Which davit type is specifically designed so that, once released, the boat’s weight carries it from the stowed position to the embarkation and then launching position with minimal power?

✅ Before You Answer

• Verify whether the system has a deck or side shell track that the davit and boat assembly roll along. • Check if the davit arms are part of a cradle that travels, rather than just arms that rotate in place. • Confirm that there is no prominent curved quadrant track or simple single-pin swing typical of radial or quadrantal davits.
