You are on a power-driven vessel underway in open water. This vessel is sighted directly ahead. The distance is closing slowly. What action will you take under the International Collision Regulations and why?

This is a vessel engaged in towing and I am seeing the stern light of the tow. The tug is not however showing any lights indicating she is restricted in her ability to manoeuvre. I will however display good seamanship and keep out of her way.

The vessel is on a steady bearing and the distance is closing. I will therefore take avoiding action, altering course to starboard and sounding one short blast under rules 14 and 16.

I will maintain my course and speed. The other vessel is being overtaken and is therefore obliged to keep out of the way by rule 13.

I will keep out of her way. I am the overtaking vessel and am obliged to keep clear under rule 13.

Ships vary considerably in design and underwater shape, but does the ship’s trim ever have any influence on its steering abilities?

No, the ship will have the same steering ability and is unaffected by trim.

Yes, the ship often steers better if trimmed by the stern.

Yes, it is usually best to be on an even keel and have no trim at all.

The «Deck Operational Oil Tanker» subject provides both theoretical and practical knowledge on safely working with electrical equipment. Mastery of this information is a key indicator of an employee's competence in a relevant position on a vessel. As the 3rd officer on an oil tanker, your primary responsibilities would include assisting senior officers in the safe navigation and operation of the ship. You would be tasked with maintaining accurate navigational records, performing regular safety inspections, and ensuring compliance with all relevant maritime regulations. Additionally, you would supervise the deck crew, oversee cargo operations, and conduct regular safety drills and training exercises. As a junior officer, you would be expected to learn from and support the more experienced crew members while gaining valuable experience for future roles in the maritime industry.
