If I remember correctly, there was 1 doctor, 1 nurse and two divers plus the usual array of safety boats many of whom carry people with various degrees of first aid training. Also the RYA offered free first aid courses to all safety and racing crews at the beginning of the season.
Given this, it is obviously then down to the OOD to decide if there are grounds to curtail a race if they feel there is insufficent resources left on the course to deal with any further incidents. Given that Annie was OOD on Sunday, I don't think we could be in better hands and she has often cancelled or curtailed races even when the racers wanted to continue on safety grounds.
As racers, we can never see the whole picture so have to rely on the OOD and safety officer on duty on the day.
Personally I would not be concerned, but then we all make the decision to race or not based on the danger that we all accept any sport has the potential to bring. That's why we do it right? ... the rush of adrenaline ...
Having done Rally Driving, Hang Gliding, Parachuting, Free Falling, Gliding, Flying, Karting and an array of other sports ... they ALL carry risks. If there is professional organisation and safety, then its simply a percentage game.
My view of course, but with the team on duty in Poole, I respect their decision to continue given they had all the facts.
Like your signature says ... Powerboating because other sports only require one ball
