NORTHSTAR ORION Owner's Manual

4.3. INFLATABLE TUBES

4.3.A. TUBES
The tubes of Northstar ORION RIBs are manufactured using CSM
(hypalon) fabric. The boat has inflation chambers around the
hull. Under normal circumstances, slight overpressure can be
used, however, the boat should never be used while the tubes
are underinflated.
Although the inflatable tubes of Northstar ORION RIBs are tested
by over-pressurization and will withstand up to 30 % pressure
rises due to temperature differences, it is important to check the
pressure of the compartments at regular intervals and adjust
them to a maximum of 180 mbar (2.6 psi) to prevent premature
wear of the tubes.
Especially in summer when the air temperature is high, tubes
should be brought to working pressures during the hottest hours of
the day. In this way, overpressurization of tubes due to sun's heat
can be prevented.
