That’s one of the more weird things I’ve heard… radars are specifically designed to try to filter out any signals not their own.
Other boats might have something like the CARD system aboard to pick up other vessels’ radar: http://nordkyndesign.com/collision-avoidance-at-sea-ais-alarm-project/ <http://nordkyndesign.com/collision-avoidance-at-sea-ais-alarm-project/> But those systems haven’t been available new for a decade. The other type of device that you could have on your vessel to help other radar-equipped vessels see you better would be an active radar target augmentation system like the Echo-Max: https://www.echomax.co.uk/radar-target-enhancers-x-band-dual-band.html <https://www.echomax.co.uk/radar-target-enhancers-x-band-dual-band.html> Or a Search and Rescue Transponder (SART): http://www.offshoreblue.com/safety/sart.php <http://www.offshoreblue.com/safety/sart.php> — Fred Fred Street -- Minneapolis S/V Oceanis (1979 C&C Landfall 38) -- on the hard in Bayfield, WI :^( > On Feb 2, 2018, at 11:42 AM, Damian Greene via CnC-List > <cnc-list@cnc-list.com> wrote: > > Here's a question for your collective wisdom: > > We regularly have fog here in Maine, and my normal practice is to hoist a > Davis emergency radar reflector in the shrouds (so I hopefully will not get > run over by a lobster boat).
