Gate is the name given to the lower barrier of a canal lock. A Canal lock is used to lower and raise the water to move boats along a waterway.
No, the Suez Canal is at sea level throughout its length.
A canal lock cill is the bottom part of a lock chamber that serves as a barrier between the water levels on either side of the lock. It is typically constructed from durable materials to withstand the forces of water and the weight of vessels passing through. The cill is crucial for maintaining water levels within the lock, ensuring safe and efficient navigation. It also helps prevent water from flowing out of the lock when it is being filled or emptied.

Locks are necessary to lift barges and canal narrow boats up or down through a series of lock gates. The water level at the start of a series of lock gates may be higher or lower than the water level at the other end of the lock gates. Without the retaining effect of lock gates, the canal would simply be dry in some lengths and wet in others.

They have pumps,drainage valves and receivers ( akin to ballast tanks on subs) to alter trim to prevent this from happening, this is more complex than, say, a Bath tub.
"Raises the ship in the canal" typically refers to the operation of a lock system in a canal, which allows boats and ships to navigate changes in elevation. By raising the water level within the lock chamber, vessels can be lifted to a higher section of the canal or lowered to a lower section. This engineering marvel helps facilitate transportation and trade by connecting different bodies of water with varying heights. Locks are essential for maintaining navigability in many inland waterways.

I think that you mean 'lock' and not loch. A lock on a canal or river allows water level to be raised or lowered so that boats can go upstream or downstream.
