Ain't gonna happen.


I know. Today's typical boat owner is
a new breed...clueless, happy to
remain so, unwilling to learn even
the most basic skills, do any manual
labor, or take any responsibility for
ensuring the safety of his own
boat...if I've heard "that's why I
have insurance" once, I've heard it
100 times! Perhaps if the insurance
industry stopped paying claims for
preventable losses.... But that
ain't gonna happen either.

Btw, Doug... Not all bilge pump
thru-hulls are above the waterline???
That's nutsy design...how can a pump
empty out a boat through a hole
through which water can come in
faster than the pump can push it
out??? Otoh, I just learned that a
lot of cockpit drain through-hulls
are also below the waterline...which
makes no sense to me
either...sigh...

Hi - the pump outlet issue is one I
know first hand...
On a sail boat the bilge pump outlet is
frequently underwater when heeled,
and for well designed sailboats with
the outlets on the transom to avoid
this
issue, the wave they generate making
way can sometimes reach the outlets...
No loop, sticky valve and glug, glug,
glug... ;o)
