Default Boat Sank due to Syphoning Effect

Trying to tell people to install vented loops is like trying to get them to
close seacocks when they leave the boat for extended periods. Ain't gonna
happen.


Yep. And that's why somany boats are in the shape they're in.


When you tell people they should close all the through hulls prior to
leaving they say that is not what they are for, or that would take to long,
or don't you trust your hoses, or I can't get too my through hulls,,,,and
that is why most boats sink at the dock.


Yep again. "That's not what they're for"??!? Gee what are
they for then?

"Can't get to my thru-hulls"?!?!!?!!!???!! Why did you buy a
freekin' boat with inaccessible thru-hulls?

Another common one is people who don't know where their
thru-hulls are.


You should see the looks I get from the yard when I tell them the ignition
key is hanging on the closed raw water engine intake and they will need to
open the intake when getting the key to start the engine.


Another goody is people not closing their fuel tank valves.

Yup, my cousins bilge pump started syphoning and sank his boat.

I don' TEEENK that's what happened...for a couple of reasons: bilge pumps
don't bring water INTO the boat, they remove water FROM the boat...and the
thru-hulls for bilge pumps are above the waterline.


Umm, not all of them are.


The water that sank your cousin's boat had to be coming in somewhere
else...and either the bilge pumps clogged and failed, or they kept pumping
till they drained the batteries and died...allowing the boat to fill up
and sink. Or, the water was coming in faster than the bilge pumps could
keep up with it. Or any combination/all of the above.


Rainwater can do it. Also if shore water supply is left
hooked up, and a leak begins (or a hose blows out); that is
a very common way boats sink at the dock (accoring to
insurance). I guess leaving shore water hooked up goes on
the list with leaving thru-hulls & fuel valves open....
