How to Keep Your Boat From Sinking
Photos
by David H. Pascoe, Marine Surveyor

I
caught this boat in the process of sinking. The
white arrow shows where the water is running into
the hatch opening. In this case the scupper is only
one inch above the water line. The owner rejected
my recommendation to close off the scuppers and
three months later it sank. |
 |
This
boat sank three times before anyone found out what
the problem was. The scupper is 2.5" above
the normal water line which is shown by the white
line on the boot stripe. |

The
inside view of the scupper showing that it is only
two inches away from a deck hatch. The owner thought
it was water tight but tests showed that it leaked
as much as 12 gallons per hour. The gasket - as
shown by arrow - was jammed with dirt. But even
when cleaned it still leaked. |
 |
This
plastic fitting was not a year old when it cracked.
It was poorly designed and could not withstand the
weight of a large hose attached to the nipple behind. |

 |
A bilge
pump discharge hose that is lacking a riser loop,
installed this way by the builder. Only 3"
above the water line, it sank the boat. |
