AIRTIGHTNESS OF THE INFLATABLE TUBE
The tube is considered to be airtight if it retains the recommended inflation pressure for 8 hours.

As the inflatable tube is a primary safety feature - check the airtightness of your boat regularly.
Inspect the condition of all inflatable components and remember that some natural release of
pressure (see the information below) can occur. Make sure that:
 There are no material cracks, holes and leaks.
 All inflation valves and seams are intact.
 ISO 6185 standard permits up to 20% loss of pressure in any compartment within 24 hours.
 If you discover a significant reduction in pressure add some air using the foot pump supplied.
Never use high-pressure equipment to inflate your boat;
Changes in ambient temperature have a significant influence on air pressure within the tube. A
variation of 1°C results in a variation in pressure of about +/- 4 mb (0,06 psi).
