Catalina 16.5 Fin keel
Last update: 25th March 2020
The Catalina 16.5 is a 16’4” (4.98m) dinghy designed by Gerry Douglas (United States). She is built since 1994 by Catalina Yachts (United States). The Fin keel version adopts a classical fin configuration, the easiest option to provide a low center of gravity.
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.

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.
