2.1 General

  2.1.1 A craft should be provided with:

  • (a) stability characteristics and stabilization systems adequate for safety when the craft is operated in the non-displacement mode and during the transient mode; and

  • (b) buoyancy and stability characteristics adequate for safety where the craft is operated in the displacement mode, both in the intact condition and the damage condition.

  2.1.2 Account should be taken of the effect of icing in the stability calculations. An example for established practice for ice accretion allowances is given at Appendix I for the guidance of Administrations.

  2.1.3 For the purpose of this and other chapters, unless expressly defined otherwise, the following definitions apply:

  • (a) "Length (L)" means length of the rigid hull measured on the design waterline in the displacement mode.

  • (b) "Breadth (B)" means breadth of the broadest part of the rigid hull measured on the design waterline in the displacement mode.

  • (c) "Design waterline" means the waterline corresponding to the loaded displacement of the craft when stationary.

  • (d) "Weathertight" means that water will not penetrate into the craft in any wind and wave conditions up to those specified as Critical Design Conditions.

  • (e) "Skirt" means a downwardly-extending, flexible structure used to contain or divide an air cushion.

  • (f) "Fully submerged foil" means a foil having no lift components piercing the surface of the water in the foilborne mode.
