The bell umbilical is generally not intended for lifting the bell. The bell umbilical is connected to through-hull fittings on a closed bell, which are connected to the bell panel inside, for distribution to the interior of the bell and to the divers via the diver's umbilicals. The bell gas panel is operated by the bellman. [1] [4]
A hull is the watertight body of a ship, boat, submarine, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline.

If the motor is trimmed out too far, the bow will ride too high in the water. With too little trim, the bow rides too low.
