Radar reflectors are used by sailboats, motorized recreational craft, and working boats of all sizes to increase their potential appearance on the radar of other vessels; the more obvious the “return” on a radar screen, the more likely an attendant boat captain is to avoid collision. However, concrete information is lacking on just how effective radar reflectors are in helping sea kayaks appear on radar.
The purpose of this study was to review the effectiveness of a variety of commercial and homemade radar reflectors in increasing the visibility of sea kayaks on radar. It is intended that the results of this study will 1) raise awareness about the efficacy of radar reflectors on sea kayaks; 2) provide all users of our coastal waters with knowledge to reduce the risk of radar-equipped vessels colliding with sea kayaks; and 3) begin a dialog between motor-/sail- vessel operators and sea kayakers along the coast of Maine.

For those interested in the details of the study set-up, this field data form was created to track 'hits' and 'misses' of reflector-equipped kayaks on a radar screen at various distances and settings. (For details on how radar works, please refer to the study report.)
