But if fitted with steadying sail, it will have a sail area in square metres that is less than 0.07 times the fully loaded mass (displacement) in kilograms raised to the power of two-thirds. The table above illustrates what this means in practice. Approximate intermediate values can be obtained by interpolation. If in doubt, check using the formula. Hazards for non-sailing boats All forms of non-sailing boats are exposed to the following hazards: a) filling with water when upright, due to insufficient freeboard or watertightness of decks or closures; b) filling with water when heeled, either over the gunwale or through openings in the hull; c) capsize or excessive heel due to movement of the people onboard, or in a few cases the wind; d) capsize due to the effects of waves (principally in Design Categories A and B). Those boats with a lot of top hamper also need to consider the heeling effect of the wind. Different styles of boat counter
