You may limit your answer to my question to the period for which
the more
detailed numbers you presumably have are available.

Dave,

I think your answer, if not directly available, can be implied by
the stat I quoted on an earlier date:

-------------------------------------------
Boats (12,000,000 - of which sail and Aux sail 40%)

Deaths pa 800 (5 times as many injuries)
0.25 per 100,000 of population
7 per 100,000 boats
2.8 per 10,000,000 hours (heroic assumption; 250hrs per boat pa)
However: sailboats are only 1% of deaths!
-------------------------------------------

It would be reasonable to assume that if sail and auxiliary sail
boats represented 40% of the fleet, but only 1% of the deaths,
then deaths (and severe injury for that matter) due to props on
these vessels are not significant.

And surely that's the point. There may be a target group in which
prop guards make economic sense - small motor vessels?

But perhaps there's much better value for money educating peple to
use lifejackets and buoyancy aids - whose lack is one of the
biggest contributions to death on the water.

The other major contribution - alcohol - has been tackled in cars
through draconian punishment. Very difficult to apply in the pure
leisure field of boating!
