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

The ratio sail area to displacement can be used to compare the relative sail plan of different sailboats no matter what their size. [links]
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.
The First 235 is a 21’7” (6.57m) cruiser-racer sailboat designed by Finot Conq Architectes (France). She was built between 1986 and 1994 by Bénéteau (France) with 680 hulls completed. The Swing keel version features an appendage configuration without compromise between draft and performance. The only drawbacks are the space is taken inside and the effort needed to lift the keel.
i The 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: Wind < force 9, Waves < 10m
B: Wind < force 8, Waves < 8m
C: Wind < force 6, Waves < 4m
D: Wind < force 4, Waves < 0,5m
The JPK 38 Fast Cruiser is as well listed, on Boat-Specs.com, in Fin keel version (see all the versions compared).
