Ali McRae made enquiries about this topic, and received the following reply from Bronwyn Hansson of the Australian Wooden Boat Festival (edited to the relevant bits) :
Re your registrations, great idea to get boat owners to register their own boat ... they have until 20th Oct for Boats Afloat and for Boat Ashore 15th December (boat Ashore can be a bit elastic)...
Please get them to put down that they are in the RAID. Ask them to put it in the same box as they put the name of their boat also put in RAID ie "Swiftsure (RAID)"
