BS EN ISO 6185-4:2018

This part of ISO6185 specifies the minimum safety characteristics required for the design, materials, manufacture and testing of rigid inflatable boats (RIBs) with a hull length of between 8m and 24m and with a motor power rating of 15kW and greater.

This part of ISO6185 is applicable to TypeIX and TypeX RIBs intended for use within the operating temperatures of −20°C to +60°C.

• TypeIX: Powered boats, fitted with a buoyancy tube covering at least 85% of the port and starboard sides, suitable for navigation in inshore and sheltered waters, up to and including wind force 6 Beaufort and significant wave heights up to 2m (design categoriesC and D), with a hull length of between 8m and 24m and with a motor power rating of 15kW and greater.

• TypeX: Powered boats, fitted with a buoyancy tube covering at least 85% of the port and starboard sides, suitable for navigation in waters, up to wind force8 Beaufort and significant wave heights up to 4m (design categoryB), with a hull length of between 8m and 24m and with a motor power rating of 75kW and greater.

NOTE1 General arrangements of typical boats of TypesIX and X are given in AnnexesA and B, respectively.

NOTE2 For boats with power ratings of 4,5kW and less, refer to ISO6185‑1. For boats with power ratings of 4,5kW to 15kW inclusive, refer to ISO6185‑2. For boats with a hull length of less than 8m and power rating of 15kW and greater, refer to ISO6185‑3.

Boats outside these types or outside of TypeIX and TypeX, as defined, are outside of the scope of ISO6185.

NOTE3 For inflatable boats with a hull length greater than 8m, it is suggested to use the requirements of ISO6185‑3.
