Here it is verbatim:
Additional Equipment - In addition to the above requirements, each vessel
a) equipped with a PLA approved and operational Automatic
Identification System Type Alpha (AIS A); and
b) provided with an all round yellow flashing light.
With best wishes
Class A transponders are typically around thrice the price of class B. A good class B black box transponder is around the £500 mark, Class A seem to start at £1500. I'm not familiar with the Class A market, but Comar seem to pop up regularly. The major commercial producers, Furuno, raymarine, simrad all do a unit. The cheapest I can find is the McMurdo Smartfind M5 at £1500.
PS, just read your last post, if the AIS has to be PLA approved, my first call would be to the PLA & ask them for a list of their approved units.
