Got an information email about the weekend today, actually read the notice of race and entry stuff and it doesnt seem to say anywhere about PFD or Flares, I assume the 2 smoke flares and type whatever PFD are still necessary.
Does say you must wear the supplied rashy at all times

while competing. And mentions your equipment must be fit for purpose. Might mean we dont get t-shirts in the goody bag, pity as its the only way I can remember which years I entered in.
There is also a prize draw for entries before December 21 (get your entry fee back and a t-shirt), so if you are undecided it might be time to go for it !
