BUOYANCY CHAMBER
–
PRESSURE
NOTE:
Observing a slight air loss before screwing the valve cap on is perfectly normal.
Only the plugs provide final airtightness.
PRESSURE
The tube has
5
compartments. Each one should be at a pressure of
240 mb / 3.4 PSI
.
It is the buoyancy chamber's correct pressure.
The ambient temperature of the air or the
Ambient temperature
Pressure inside the

water proportionally influences the
+1°C
+4 mb / 0.06 PSI
internal pressure of the buoyancy chamber.
-1°C
-4 mb / 0.06 PSI
It is therefore important to be able to anticipate changes.
Check and adjust the pressure of inflatable compartments (by inflating or deflating) depending on
the temperature (particularly when temperature variations are high between the morning and
evening in particularly hot regions) and check that the pressure does not exceed the recommended
pressure zone (from 220 to 270 mb).
RISK OF PRESSURE LOSS
Example:
Your boat is exposed to bright sunlight on the beach (temperature = 50°C) at the recommended
pressure level (240 mb/3.4 PSI). When you put it in the water (temperature = 20°C), the temperature
of the inflatable compartments and the pressure inside them will fall in step (by up to 120 mb) and
YOU WILL NEED TO REFLATE
to regain the millibars lost due to the difference in temperature between
the ambient air and water.
It is normal to observe a drop in pressure at the end of the day when the outdoor temperature drops.
