Hanse 505 shoal draft

The Hanse 505, here in "shoal draft" version, is a 48’8” monohull sailboat designed by Fietje Judel and Rolf E. Vrolijk. She was built by Hanse (Germany) and made of monolithic bottom, sandwich sides and deck: balsa / fiberglass / polyester. The production started in 2014 .

The Hanse 505 is as well listed, on Boat-Specs.com, in version Standard.

Hanse 505's   Performances
Upwind sail area to displacementiThe 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 23 it indicates a fast sailboat.
20.49
Displacement-Length ratio (DLR)iThe Displacement Length ratio is a figure that points out the boat's weight compared to its waterline length. 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.
160
Ballast ratioiThe Ballast ratio is an indicator of the stability; it is obtained by dividing the boat's displacement by the weight of the ballast. Since the stability depends also of the hull shape and the position of the center of gravity, only boats with similar ballast arrangements and hull shape should be considered.
Higher the ballast ratio is, greater is the stability.
29 %
Righting moment @ 30°iThe righting moment is a moment (torque) that tends to restore a boat to its previous position after a rotational displacement. 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 at this angle.
57141 lbs.ft
Maximum righting momentiThe righting moment is a moment (torque) that tends to restore a boat to its previous position after a rotational displacement. 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 at this angle.
66544 lbs.ft @ 50.00 °
Hull speediAs 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.
