Final answer:
As the operator of a stand-on vessel, you are required to maintain your course and speed, following the maritime 'Rules of the Road' to prevent collisions.
Step-by-step explanation:
When encountering another vessel, as the operator of the stand-on vessel, you must maintain your course and speed. This is part of the navigational rules that are designed to prevent collisions at sea. These rules, often referred to as the 'Rules of the Road,' stipulate that the stand-on vessel has the right of way and should continue on its course to allow the give-way vessel to take action and avoid a collision. As the operator of the stand-on vessel, when encountering another vessel, you must maintain your course and speed. This means you should continue moving in the same direction and at the same speed. By doing so, you are indicating to the other vessel that you have the right of way and they should alter their course to avoid a collision.
