In sport, work, rescue and military versions, these boats consist of a hull and double hull of strengthened fibreglass, which are joined and sealed, and form a watertight compartment with an important floatability reserve.
The inflatable tube, which surrounds the hull, is manufactured based on watertight compartments that supply an additional floatability reserve and, moreover, contributes to the great stability and the capacity to absorb the impact of navigation in severe sea conditions.
