When a davit-launched raft is lowered from a MODU, upon becoming waterborne, the raft is released by __________.

Correct Answer: Option D — the effects of buoyancy removing the weight of the raft from the hook

Davit-launched liferafts utilize an automatic release hook mechanism. Once the craft becomes fully waterborne, buoyancy removes the gravitational downward pull on the hook, allowing it to trip open automatically or manually without remaining bound under load, conforming to 46 CFR survival craft requirements.
