Buoyancy distribution

3.2.1 Buoyancy must be evenly distributed over the craft plan-form.

3.2.2 No contribution to intact buoyancy is to be claimed for any space or material above a level which is 75 mm below the lowest point at which water may enter the intact craft when floating in calm water at maximum designed weight.

3.2.3 Structural void contributions to buoyancy are to be bounded by watertight boundaries, and must each be provided with a watertight access panel for inspection and the removal of any accumulated water. Any penetrations of buoyancy void boundaries must be watertight.
