This information comes from Sail Calculator, a website which calculates various data about different boat models.

I found the information very informative, especially the indices on motion comfort and capsize ratio for the Cascade 36. In summary the Cascade 36 is a fast cruiser which is generally safe (although this would depend more on the crew than the boat) and has a comfortable motion. Of course this is borne out by my experience with her. Below is the information. I would be interested in readers looking at the data for their own boats and letting us know whether they agree with the conclusions.

Loa: 35.56
Lwl: 28.87
Beam: 9.95
Displacement: 12829lb
Sail Area: 678

Displacement to LWL: 238
Explanation: A medium value would be 200. 300 would be high (Heavy Cruising Boat) and 100 would be low (Ultra Light Displacement-ULDB). Boats with low numbers are probably uncomfortable and difficult to sail.

Hull speed: 7.2
Explanation: This is the maximum speed of a displacement hull. Some racers and lighter boats are able to achieve greater speed by lifting over the bow wave and riding on top of the water,that is, planing.

Sail area to displacement: 19.79
Explanation: The sail area is the total of the main sail and the area of the front triangle. I cannot be sure that this datum was entered correctly for each listed boat. A racing boat typically has large sail area and low displacement. A number less than 13 probably indicates that the boat is a motorsailer. High performance boats would be around 18 or higher.

Lwl to beam: 238
Explanation: A medium value would be 2.7. 3.0 would be high and 2.3 would be low.

Motion Comfort: 29.87
Explanation: Range will be from 5 to 60+ with a Whitby 42 at the mid 30’s. The higher the number the more comfort in a sea. This figure of merit was developed by the Yacht designer Ted Brewer and is meant to compare the motion comfort of boats of similar size and types.

Capsize ratio: 1.7
Explanation: A value less than 2 is considered to be relatively good; the boat should be relatively safe in bad conditions. The higher the number above 2 the more vulnerable the boat. This is just a rough figure of merit and controversial as to its use.

Pounds/inch (displacement): 1026
Explanation: The weight required to sink the yacht one inch. If the boat is in fresh water multiply the result by 0.975. If you know the beam at the waterline (BWL) multipy the result by BWL/Beam.

Sailing Category: Racer/cruiser
Explanation: The four categories are racer, racer/cruiser, cruiser/racer, and cruiser in order of descending performance
