If a boat is made of non metallic materials what is needed in order to help larger vessels see the boat on radar screens?

To help larger vessels detect a boat made of non-metallic materials on radar screens, the boat can be equipped with radar reflectors or transponders. Radar reflectors are designed to bounce radar signals back to the source, making the boat more visible on radar. Additionally, installing an Automatic Identification System (AIS) transponder can enhance visibility, as it broadcasts the boat's position and information to other vessels.
