Parent topic: Annex 6 - Methods Relating to the Intact Stability Investigation of Hydrofoil Craft

2.1 Hull-borne mode

  2.1.1 The stability in the hull-borne mode should be sufficient to satisfy the provisions of 2.3 and 2.6 of this Code.

  2.1.2 Paragraphs 1.1.2 to 1.1.5 of this annex are appropriate to this type of craft in the hull-borne mode.

2.2 Transient mode

  2.2.1 The stability should be examined by the use of verified computer simulations to evaluate the craft's motions, behaviour and responses under the normal conditions and limits of operation and under the influence of any malfunction.

  2.2.2 The stability conditions resulting from any potential failures in the systems or operational procedures during the transient stage which could prove hazardous to the craft's watertight integrity and stability should be examined.

2.3 Foil-borne mode

 The stability of the craft in the foil-borne mode should be in compliance with the provisions of 2.4 of this Code. The provisions of paragraph 2.2 of this annex should also apply.

2.4

 Paragraph 1.2.2 of this annex should be applied to this type of craft as appropriate and any computer simulations or design calculations should be verified by full-scale tests.
