Canadian Boating Practice Exam – Prep, Practice Test, Questions & Study Guide

A radar reflector should be mounted as high as possible to be effective on boats less than 20m in length. This is because the higher the radar reflector is mounted, the more visible it will be to other boats' radar systems. This is especially important for smaller boats, as they may not have a strong radar signature and are at a higher risk of being missed by larger vessels. The other options, such as a fitted bell, special flashing light, and masthead lights, may also be important safety features to have on a boat, but they are not directly related to the effectiveness of the boat's radar system.
