You are on a sailing vessel, underway in open water. This vessel is sighted on the starboard bow, on a steady bearing and the distance is closing. By the International Regulations for the Preventing Collisions at Sea, what action will you follow?

Risk of collision is deemed to exist and, as the other vessel is on a steady bearing on my starboard side, I will maintain my course and speed.

This vessel is clearly a power-driven vessel and I anticipate that the bearing will therefore close and she will pass ahead at a safe distance.

The «Cargo Handling and Stowage, Management, Oil Tanker» subject provides both theoretical and practical knowledge on safely working with electrical equipment. Mastery of this material is a key indicator of an employee’s competence in their role aboard a vessel. Cargo handling and stowage on an oil tanker involve the processes of loading, unloading, and storing liquid cargo, such as crude oil or petroleum products.
