I encourage you not to fall into the same trap the boating industry often uses to deflect attention. They say we have not seen any accidents EXACTLY like this one for a long time (not the same boat builder, the same horsepower, the same type of drive, fatality, within the last 5 years, etc). Sometimes it seems to us like they would like to add "on a Tuesday afternoon". Youth sailing propeller accidents do not happen every day HOWEVER the U.S. Coast Guard openly admits most boating accidents meeting their reporting criteria go unreported. That makes the existing data more valuable. I suggest you consider broadening the applications AND geography AND time span to get a better picture of what is going on.Agreed, if you have a prop guard it makes a prop strike fatality much much less likely... problem is, that's a pretty rare circumstance. Of 2 the other youth sailing fatalities reported in the last decade (total of 3) the other two were rigging entanglement in a capsize. I don't know what other forms of accidents have been suffered, it would be very interesting to hear about European and Australian youth accident reports; from a standpoint of preparing for the real hazards rather than imagining what-might-go-wrong scenarios.
I suggest looking at fatal AND non fatal propeller accidents involving coaching, escort, and safety boats across youth sailing, open water swimming, canoe races, rowing, sculling, and other similar events here and abroad. It gives you a better view of what brings about these accidents. Much of that data inside AND outside the U.S. will be limited to media reports.
For example, I copied the text below from our site:
"two boys were taking sailing training with a safety boat about 50 meters in front of them with Royal Yachting Association (RYA) handlers on board. Then one boy fell into the water and the sailboat was still upright. The boy remaining onboard was having trouble pulling up the boy that fell in, in part because his safety harness was catching on the hull. The crew on the safety boat decided to help. They put their boat in neutral. The helmsman was moving across the safety boat to assist, when he slipped and grabbed the throttle which also pulled the safety boat into gear. He immediately pulled the kill switch, but his boat had swung sideways, its propeller struck the boy’s leg and caused serious injuries. The boy was taken to a nearby hospital where his leg had to be amputated. The accident was written up as Incident Number 8 in a MAIB safety series. Posted online by Sail-World 24 August 2009 along with a list of 4 lessons learned (lessons posted 23 August 2009)."
Back to my previous post,
Yachting Australia also issued a safety information notice 26 August 2013 "The use of propeller guards for outboard engines at training centres and clubs where there is dinghy and windsurfing training." http://www.sailing.org.au/wp-content/uploads/2013/10/sin-2-130826-propeller-guards.pdf
Back to RYA, in UK Water-Related Incident Database Gap Analysis Final Report RSM/06/14 for Health & Safety Laboratory (a UK safety research firm) they interviewed RYA for their 2014 report. "From the telephone interview it was established that the RYA do not currently collect or collate any accident information. In a small number of cases they may respond to accident information (i.e. through basic investigation if the incident relates to the RYA directly). "
RYA had not taken advantage of their position to record accident data of any kind.
