BUOYANCY CHAMBER - Pressure
RISK OF PRESSURE LOSS
EXAMPLE:
Your boat is exposed to direct sunlight on the beach (temperature=50°C)
at the recommended pressure (240 mb/3.4 PSI). When you launch it (temperature=20°C), the
temperature and internal pressure of the inflatable compartments will drop simultaneously (up
to 120 mb) and
YOU WILL THEN NEED TO REINFLATE
until you regain the millibars
lost due to the difference between the ambient air and water temperatures. A drop in pressure
at the end of the day, when the outside temperature is dropping, is normal.
RISK OF OVERPRESSURE:
EXAMPLE:
Your boat is inflated to its recommended pressure (240 mb/3.4 PSI) at
the beginning or end of the day (low outside temperature = 10°C). Later in the day, your boat
is exposed in the sun on the beach or on a yacht deck (temperature = 50°C). The temperature
inside the inflatable compartments may rise to 70°C (particularly for dark buoyancy
chambers), doubling the initial pressure (480 mb).
YOU WILL THEN NEED TO
DEFLATE
the boat to return to the recommended pressure.
WARNING
IF YOUR BOAT IS OVERINFLATED, THERE WILL BE UNDUE
PRESSURE ON THE INFLATABLE STRUCTURE THAT MAY
RUPTURE IT.
IN CASE OF OVERPRESSURE
EASY PUSH VALVE:
Release air by depressing the
valve plunger
