We do not use AIS because the hazards would not show up, fishing boats, crayfish pot markers and little runabouts (fishing). Commercial boats that are required to have AIS, 300t + are usually well lit and on regular routes (and show up well on radar).
Most fishing vessels here over roughly 35' have AIS. I don't believe it is compulsory fit but it is handy if you have a receiver. Potters tend not to, although some do, but they're less likely to be out in rough weather.
