Rawson 30 specs

Rawson 30 sailboat information and Rawson Specifications

D/L RATIO: 503
Displacement to LWL: 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.

SA/D RATIO: 12.52
Sail Area to Displacement: The sail area is the total of the main sail and the area of the front triangle. 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. (14 = low, 22 = high)

BAL/D RATIO: 41.6
Ballast to Displacement: (33-45 is average, higher=more stability)

LWL/BEAM: 2.44
LWL to Beam: A medium value would be 2.7. 3.0 would be high and 2.3 would be low.

CAPSIZE RATIO: 1.57
Capsize Ratio: A value less than 2 is considered to be relatively good; the boat should be relatively safe in bad conditions. The higher the number is above 2 indicates the more vulnerable boat. This is just a rough figure of merit and controversial as to its use.

MOTION COMFORT: 40.12
Motion Comfort: Range will be from 5 to 60+. The higher the number means 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 sizes and types.

HULL SPEED: 6.29 knt
Hull Speed: 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 (planing).

These are the Outfitting specifications for the Rawson 30 as provided by Ron Rawson.
