1.5.2. Hull openings, seacocks
Openings in the hull are possibly hazards for the penetration of water. They request special
attention.
Fittings and cocks were selected according to approved technical regulations and standards.
Because they are manual controlled the status of the sea cock should be checked regularly.
All through hull fittings should be revised or replaced latest every 5
years.
All through hull fittings below the waterline can be closed. If you leave the boat close all sea
cocks.
For safety reasons the hose connectors are provided with double hose clamps. Do not change
this!
Through hull fittings for instruments, i.e. sensor for the echo sounder, are special designed and
can not be closed like as a seacock.
Close the sea cocks if they are not in use and between the Sailing.
The status can be recognized by this:
Closed – crosswise lever-direction to the hose
Open – longitudinal lever-direction to the hose
To avert danger you should keep leak stoppers in different sizes on board. They should be made
of soft wood in various diameters to fit well into the different sizes of board ducts and could close
every opening safely.
