In The Event Of Overpressure - Zodiac PRO 750 Eignerhandbuch

BUOYANCY CHAMBER - Pressure
Thus, it is important to anticipate:
Check and adjust the pressure in the inflatable compartments (re-inflating or deflating
as necessary) depending on changes in the temperature (particularly when there is a big
difference in temperature between the morning and the evening in very hot climates).
Check that the pressure does not go outside the recommended pressure range (from 220
to 270 mbar / green area).
Risk of underpressure
Example: The boat is exposed to direct sunlight on the beach (temperature = 50°C) at the
recommended pressure (240 mbar/3.4 PSI). When putting the boat in the water (temperature =
20°C), the internal temperature and pressure in the inflatable compartments will both drop
(down to 120 mbar). It is then necessary to re-inflate to make up for the millibars lost due to
the difference in temperature between the ambient air and the water. It is also normal to note a
reduction in pressure at the end of the day when the outside temperature drops.
WHEN UNDER-INFLATED, THE BOAT LACKS RIGIDITY
WHEN UNDERWAY, ITS PERFORMANCE IS REDUCED AND
IT RISKS AGEING PREMATURELY.
NOTE
Risk of OVERPRESSURE
Example: The boat is inflated to its recommended pressure (240 mbar/3.4 PSI) at the
beginning or end of the day (lowest outside temperature = 10°C). Later in the day, the boat is
exposed to direct sunlight on the beach or on the deck of a yacht (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). It is then necessary to deflate in
order to return to the recommended pressure.
IF YOUR BOAT IS OVERINFLATED, THERE WILL BE UNDUE
PRESSURE ON THE INFLATABLE STRUCTURE THAT MAY
RUPTURE IT.
