J. The Effect of Boats Moored Along Side
2.. Excessive.or.unequally.distributed.weight.
A.boat.operator.should.be.aware.that.carbon.monox-
ide.is.emitted.from.any.boat’s.exhaust..The.operation,.
mooring,.and.anchoring.in.an.area.containing.other.
boats.may.be.in.an.atmosphere.containing.CO.not.of.
the.operator’s.making..An.operator.likewise.needs.to.
be.aware.of.the.effect.of.their.boat.on.other.boats.in.
the.area..Of.prime.concern.is.the.operation.of.an..
auxiliary.generator.where.boats.are.moored.along.
side.each.other..Be.aware.of.the.effect.your.exhaust.
may.have.on.other.boats.and.be.aware.that.the.
operation.of.other.boats’.equipment.may.affect.the.
carbon.monoxide.concentration.on.your.boat...

3. Canvas configurations – Under various conditio-
ns,.adding.or.removing.canvas.may.raise.or.lower.
CO.levels..See.Figures.B-8,.B-9.&.B-11.
EXHAUST FUMES!
Hull exhaust from your boat can cause
excessive accumulation of poisonous carbon
monoxide gas within cockpit areas when using
protective weather coverings (while underway
or while stationary). Provide adequate ventila-
tion when the canvas top, side curtains and/or
back (aft) curtains are in their closed protective
positions.

K. Backdrafting (Station Wagon Effect)
Backdrafting.or.the.“station.wagon.effect”.is.caused..
by.air.movement.over.or.around.a.boat.creating.a.low.
pressure.area.or.suction.area.around.the.stern.that.
can.increase.CO.level.on.the.boat..Backdrafting.can.
be.affected.by.relative.wind.direction,.boat.speed,..
and.boat.trim.angle..See.Figure.B-8.Backdrafting.–..
Airflows Over Boat and Behind Transom”.
4.. Opening.and.closing.ports,.hatches,.doors,.and.
windows.may.raise.or.lower.CO.levels.on.board..
a boat. When airflow is moving forward inside the
boat,.CO.may.be.entering.the.boat..See.Figures.
B-10.and.B-11.

and behind transom
Under.certain.speed.and.operating.conditions,.the.low.
pressure.area.may.form.in.other.regions.and.permit.
carbon.monoxide.to.enter.the.hull.through.openings.
