Those big boats can (and do) filter out all signals from AIS-B

they still don't see you.
If they do - they are at least at a legal disadvantage should a
collision happen.
An argument to fit an AIS-A transponder :-)
In this case an active radar reflector would be better, as it cannot be
filtered.

An active radar reflector is the way to go. The only problem is it takes
electrical power.
Power boats with a large generator have no problem.
The next best thing for a sailboat is an adequate passive radar reflector.
I am looking at the Tri Lens Radar Reflector.
It is always best to know the traffic on or close to your route.
This is best done when you are planning your route.
When this is not possible I check for traffic with the Coast Guard.
Over here we use Fundy and Halifax Traffic I visited their office and they
have the latest of equipment and land base radar antennas all around the Bay
and the gulf of Maine.
When entering narrow passages under heavy fog I prefer to make my self known
by being in radio contact with the traffic dept and the vessels in my
vicinity.
