Canadian Boating Practice Exam

Passive radar reflectors are required on all pleasure crafts less than 20m in length or those constructed of non-metallic materials. This is because larger boats are typically made of metal and have a larger radar signature, making them easier to detect on radar. Smaller boats or those constructed of non-metallic materials may not have a strong enough radar signature and require a passive radar reflector to be detected by other vessels, especially in low visibility situations such as at night. Therefore, options A, C, and D are incorrect as they do not provide the correct criteria for boats that must be equipped with a passive radar reflector.
