a Boats using options 1, 3 and 6 are considered to be susceptible to swamping when used in their design category.
b That is, any boat that is not 'fully enclosed', thus including boats without any decking.
c This term is defined in 3.1.5.
d This term is defined in 3.1.6.
e The downflooding height test is not required to be conducted on the following boats:
- those which, when tested in accordance with normative annex C.4.3, have been shown to support, in addition to the mass required
by C.2 and Table C.5, an additional equivalent dry mass (kg) of (75∙CL + dry weight of stores and equipment included in the maximum
total load), or
- those boats that do not take on water when heeled to 90° from the upright in the light craft condition.
f This test only applies to boats of design category C.
g The application of Worksheet 8 is only required for boats where ALV / (LH BH) ≥ 0,5.

Note whether it is asymmetric by adding P (port ort S (starboard) to denote the larger side)
Sketch: Indicate possible seating locations along the length of the side to be tested using numbers, so that these may later
be used to record the positions that people actually occupy. Locations should not be closer than 0.5 m between centers,
and not less than 0.2 m from outboard edge unless on sidedecks less than 0.4 m wide.

Normative annex E
Objective: to show that the buoyancy available from the hull structure, fittings and flotation elements equals or
exceeds that required to support the boat as loaded for the swamped load test.
Objective: to demonstrate that a boat can be returned to the upright after a capsize by the actions of the crew using their body action
and/or righting devices purposely designed and permanently fitted to the boat, that it will subsequently float, and to verify that the
recommended minimum crew mass is sufficient for the recovery method used.
The internal arrangement facilitates the drainage of water to bilge suction point(s), to a location from
which it can be bailed rapidly, or directly overboard?
