I would like to get the Breezers opinion on this. I work part time for the department of transport as an examiner and have over 25 years of ocean sailing experience. The DoT regulations allow the use of inflatable PFDs as do AORCA and Canoeing Australia. The organisers of the Doctor are using their own regulations which will only accept a 'self inflating PFD' - ie one that inflates when you hit the water - not terribly practical for downwinders.
The other option is to wear a full bulky PFD2/3. Given that this event is already a huge event for surf skis and trying to attract SUP, I wonder whether this is the best approach in regard to safety equipment? Inflatable PFDs are commonly accepted around the world at SUP downwinder events (to my knowledge) and are accepted locally here at WA events - the Mandurah Duel for instance.
The organisers state that they are trying to avoid a situation of unconsciousness - due to heat stroke or heart attack (because of the age demographic), but they are accepting a PFD 2 and 3 which are both buoyancy vests - they have no neck collar, which means if you fall into the water unconscious you may drown as the the head cannot be held clear - which is why the Dot and marine safety require a PFD 1 for all sea going vessels.
I know the organisers are trying to do the right thing, I am just interested in everyones thoughts.
