Next, the raft is tied to the ship's rail so passengers can be loaded before the
raft is lowered into the water.
A good system if the ship is upright, but what if it is heavily tilted? Then, you
throw the raft into the water
(it autoinflates in this case), the passengers jump -- from whatever floor they're
on, and are picked up from the water.
Anyway, that is the plan.
