How does the ship avoid collisions with whales?

Most cruise liner has a “whale avoidance training” program for navigation officers and lookouts. The training certificate expires after one year and needs to be renewed each year. The training concentrates on how to look for whales, patterns of different species of whales and what to do when a whale is sighted. There are strict regulations in place for areas with dense whale populations, such as Glacier Bay in Alaska. Stringent controls are in place for reduced ship speeds and what to do when sighting a whale nearby.

In ship building, is there an optimum relationship between the length and breadth of the ship?

Answer: This depends on the wishes of the ship builder and the capacity of the yard. The relationship between breadth and length of a ship affects the speed: a narrower ship has more speed as less surface is pushing through the water, however it will have less cargo capacity and buoyancy. There are also limitations for what size ship a port can handle. The Panama and Suez Canals have a maximum width. If a ship goes around one of the capes it will have to travel more miles, but can carry more cargo.
