Yes but a leisure RIB is unlikely to choose
to go out in the conditions in which an RNLI RIB is required
to go out. The chances of losing all electrical power are, I would think, almost negligible in ordinary conditions.
Further, I'm sceptical whether any practical size of passive reflector will actually give a good return mounted on a RIB at (what) 1-1.5m above sea level, at best. The Qinetiq report
on radar reflectors was not reassuring in that regard and the Echomax tested has some poor results at larger elevations.
I wonder how well even the Sea-Me (the best performer by a long way) would work at typical RIB height.
