Your data would have some credibility if you actually could cite a
real reference. Just claiming that the official numbers are bogus
makes you sound like a crackpot.

BTW, since over half of all boating accidents are in June, July and
August, your numbers are not inconsistent the official numbers. For
example, the 2004 report includes "one hundred eighty-six (186)
accidents involve a person being struck by a motor/propeller either as
the first, second or third event in the accident sequence. These
events resulted in thirty-one (31) fatalities." Unfortunately, the
primary data only includes the first event, and that's the only way to
sort out which type of vessel was involved.

The figures are not all that accurrate at the USCG but they are working
on them and should be able to provide more detailed data soon. At the
most recent meeting the following figures were presented.

In the summer of 2005 alone, a brief and very limited media (90 days)
search, uncovered 58 exposed recreational boat propeller strikes:

34% were fatal
14% led to amputation of a limb
42% were severe lacerations requiring hospitalization for extended
periods.

(Note when we speak of "severe lacerations" from a propeller strike
we mean severe life altering/changing lacerations)

The above demonstrates an extraordinary result but unfortunately the
standard consequences, common to most grievous of boating accidents.
Worst of all we are finding far too many children from age 3-18
represented in these horrifying statistics. Similar to the automotive
industry forty years ago, the recreational boating manufactures argue
wrongly, safety is the responsibility of the operator. We believe
safety can be designed into a product and that safety is not an option,
it should be mandated. Safety does sale!
