STATISTICS
76% of all PWC
accidents in 1998 were collisions—70% with other vessels, and
6% with fixed
objects1
With Exposure
Hours factored in, PWC are 6 times more likely to be involved
in an injury accident than an open motor
boat2
PWC injury
accidents are significantly under-reported Data captured
through the National Electronic Injury Surveillance System
shows that between 1990 and 1995 an estimated 32,954 persons
with PWC-related injuries were treated in US hospital
Emergency Departments, of which 3.5% were hospitalized.
PWC-related injuries increased from an estimated 2860 in 1990
to more than 12, 000 in 1995. During that same 5-year period,
the number of PWC in operation increased 3 times, and the
number of injuries increased 4 times. The rate of ED-treated
injuries related to PWC was about 8.5 times greater than the
rate from
motorboats.3
Discussion of
Statistics as a mode of determining what education is
needed:
An argument has been
made that statistics can be manipulated for the purposes of the
manipulator. No doubt that is true. Let us look at the motives of
persons who have gathered and disseminated the statistics reported
above.
1. The US Coast
Guard.
Q. What could be
their motive in reporting the high statistic on PWC collisions?
Where did they get those numbers?
A. The US Coast
Guard is the central reporting agency, which gathers boating
accident information from all 50 states. The Coast Guard Safety
office analyses the data reported and makes safety
recommendations to marine manufacturers, and when necessary
intervenes on behalf of the consumer to insure the boating
public’s safety. The Coast Guard is heavily involved in search
and rescue operations and is very familiar with accident
scenarios. Motive? Save lives.
2. Heiden &
Associates: Hired by Kawasaki, Polaris, and Yamaha to survey the
boating public. Analysis and data supplied to the USCG.
Q. How did they
decide what a boating exposure hour is for a PWC or an open
motorboat?
A. Riding time
included time away from the dock, shore, or launch point for
both PWC and open motorboat. 60 percent of total open motorboat
time was spent in operation, and 77 percent of PWC time was
spent in operation. Motive: Try to understand what the real
risks of accident were from vessels reporting similar exposure
hours. Possible secondary motive: Hope to show PWC operation was
not that risky. (Unhappily, not so.)
3. Branche et. Al.
Emergency Department and other Health Officials.
Q. Are they
trying to make PWC look bad? Why does their report differ so
much from the USCG?
USCG stats for
1995 show only 3,986 PWC injuries. The ER Docs are saying
12,000—that makes USCG stats only ? the number seen in the ER.
What gives?
A. The Coast
Guard is not everywhere at once, and some people don’t want to
get "in trouble" so they don’t fill out an accident report, even
though it is required. As for the ER Docs, there are strict
penalties for falsifying medical records. There is no reason to
suspect a conspiracy by doctors who treat trauma. Instead, maybe
we should suspect a need to reverse the growing trend in PWC
accidents so they don’t have to go home so often thinking about
the carnage they have seen. Motive? Prevent
Accidents.
4. The Coalition of
Parents and Families for Personal Watercraft
Safety
Q. Why put out all this "negative" stuff about PWC?
Are you sure you don’t want to ban them?
A. There are many entities now involved in the PWC
Safety Discussion. At least one study has been ordered and then
pulled because of misconduct, which might have shed light
remedies for loss of steering off throttle. At least two years
were wasted, almost 300 people died in that time on PWC, and
17,000 injuries were reported to the USCG. (No continual
tracking system is in place in Emergency Departments, so unless
someone else funds a similar study to Branche et. Al. we will
not see new material.) We cannot afford to wait while more
people are injured and killed. It will be a nice day when we
have a dramatic downturn in PWC injuries and deaths to report,
and when that downturn stays consistent. OK if it makes you mad,
but better if it makes you take a boater education class, and
exercise caution at all times while operating PWC while the
"powers that be" get all the legal and technical stuff worked
through. That looks like years, and even when the design is
changed to include real off-throttle steering, we will continue
to have challenges with proper safety gear, appropriate training
for the type and speed capabilities of the craft, and
appropriate age and training of all PWC operators. We are here
for the long term. Yes, we’re sure we don’t want to ban them. If
we get on that bandwagon, nobody who likes PWC will talk with
us, work with us, or assist us in saving lives and preventing
injuries. Motive: Save lives, prevent injuries.
A final word about
statistics. If you want to seriously look at a problem with
prevention in mind, you have to study the problem, taking in all the
information you can. The best information we have is not complete,
but it is the best information we have. Rather than quibble over the
unhappy news that PWC represent disproportionate numbers of
collisions and trauma on accident reports; let’s give some credence
to the information that we have. People are more than
statistics—they are wonderfully made, and completely
irreplaceable.

1998 USCG Boating Statistics
2 1997 Boating
Exposure Survey Results. Heiden Associates, Inc. PWC incidence
per million exposure hours: 6.22, Open Motorboats: 0.94;
Canoes/Kayaks 0.25. This statement is qualified with the caution
that when interpreting these observations because of incomplete
reporting of injuries and potentially significant differences in
injury reporting rates across vessel types.
