ENVIRONMENTAL CONSIDERATIONS
Boat users must observe safe boating and
environmental practices and be aware of local
restrictions and special zones. These topics are
governed by local regulations and international
maritime law and will vary from country to country.
Skippers/owners are required to exercise the
appropriate regulations and 'Codes of Practice'
recognised and approved in the areas where the craft
is operating.
CAUTION
The discharge of fuel oils, foul waste and even food
can affect water quality by locally increasing the
biochemical oxygen demand and releasing
microbial pathogens into the environment.
Quantities discharged maybe small, but in areas
where a large number of vessels operate this can
be very apparent
Fuel oil spillages - Diesel fuel and lubricants are the
most common causes of pollution. The following
points should be observed when dealing with fuel oil
spillages:
a Never discharge engine oil or fuel overboard.
Spillages should be cleared up and placed in
sealed container for disposal at approved oil
disposal points ashore. Do not mix solvents with
oil for disposal, this combination cannot be
recycled and increases the risk of the stored
mixture.
b If washing down be aware that the overuse of
detergents when mixed with oil emulsifies and
becomes a greater problem than the oil itself.
c Avoid fuel spills at the dock by filling slowly and
not overfilling tanks, giving rise to fuel leaking
from tank breathers.
Discharge and waste disposal - Many countries have
legislation controlling the disposal of waste coupled
with heavy fines. Be aware that MARPOL regulations
regulate the prevention of pollution of the marine
environment by ships.
Non-biodegradable waste - Whenever possible this
should be retained aboard and jettisoned only in
approved disposal or recycling points ashore
Biodegradable waste - 'Biodegradable' a common
justification for throwing food scraps overboard. There
is a high chance that this will affect the oxygen levels
in a high volume vessel area. Where food has to be
disposed of overboard it should be cut-up as small as
possible to speed up the breakdown (Many European
countries restrict such disposal within 17 km (12 miles)
of their coastline)
Sewage/foul waste - As raw untreated sewage this will
increase pathogens into the water posing a potential
public health risk to swimmers and those who
consume shellfish. Where you craft is fitted with
holding tanks you should use them in preference to
pumping sewage overboard in coastal waters.
Sewage should only be discharged when over 17 km
(12 miles) offshore or at a pump out point provided in
marinas and harbours.
