Hallberg-Rassy 412's performances

Upwind sail area to displacement
 iThe ratio sail area to displacement is obtained by dividing the sail area by the boat's displaced volume to the power two-thirds.

The ratio sail area to displacement can be used to compare the relative sail plan of different sailboats no matter what their size.

Upwind: under 18 the ratio indicates a cruise oriented sailboat with limited performances especially in light wind, while over 25 it indicates a fast sailboat.
199 ft²/T18.45 m²/T
Downwind sail area to displacement
 iThe ratio sail area to displacement is obtained by dividing the sail area by the boat's displaced volume to the power two-thirds.

The ratio sail area to displacement can be used to compare the relative sail plan of different sailboats no matter what their size.
291 ft²/T26.99 m²/T
Displacement-length ratio (DLR)
 iThe Displacement Length Ratio (DLR) is a figure that points out the boat's weight compared to its waterline length. The DLR is obtained by dividing the boat's displacement in tons by the cube of one one-hundredth of the waterline length (in feet).
The DLR can be used to compare the relative mass of different sailboats no matter what their length:

a DLR less than 180 is indicative of a really light sailboat (race boat made for planning), while a DLR greater than 300 is indicative of a heavy cruising sailboat.

Ballast ratio
 iThe Ballast ratio is an indicator of stability; it is obtained by dividing the boat's displacement by the mass of the ballast. Since the stability depends also of the hull shapes and the position of the center of gravity, only the boats with similar ballast arrangements and hull shapes should be compared.

The higher the ballast ratio is, the greater is the stability.
36 %
Righting moment @ 1°
 iThe righting moment is a moment (torque) that tends to restore a boat to its previous position after heeling. Its value corresponds to the torque needed to heel the boat for this angle.
Higher the righting moment is for an angle, greater is the stability.
2119 lb.ft293 kg.m
Righting moment @ 30°
 iThe righting moment is a moment (torque) that tends to restore a boat to its previous position after heeling. Its value corresponds to the torque needed to heel the boat for this angle.
Higher the righting moment is for an angle, greater is the stability.

Maximum righting moment
 iThe righting moment is a moment (torque) that tends to restore a boat to its previous position after heeling. Its value corresponds to the torque needed to heel the boat for this angle.
Higher the righting moment is for an angle, greater is the stability.

Critical hull speed
 iAs a ship moves in the water, it creates standing waves that oppose its movement. This effect increases dramatically the resistance when the boat reaches a speed-length ratio (speed-length ratio is the ratio between the speed in knots and the square root of the waterline length in feet) of about 1.2 (corresponding to a Froude Number of 0.35) . This very sharp rise in resistance, between speed-length ratio of 1.2 to 1.5, is insurmountable for heavy sailboats and so becomes an apparent barrier. This leads to the concept of "hull speed".
The hull speed is obtained by multiplying the square root of the waterline length (in feet) by 1.34.
