I think a cannon on deck would look great on my Ericson 30+,
though I'm not sure the Coast Guard would share my enthusiasm!!
In other posts I have read periodically that many of the larger boats don't check their radar that carefully. And we recently had a ferry run into an island!! I suspect that they would likely be even less attentive to their radar on good weather days, when they are likely not anticipating the kind of situations that could arise at night or in fog. So even in the situations described above, is the radar reflector going to help much?
Also, can anyone tell me if my 30 foot sailboat with 46 foot mast will show up on their radar at all without a radar reflector--ie. is the radar reflector the only thing that will tell them I'm there (if they can't see me visually) or would I show up a bit smaller or more faintly without the reflector?
