Sailing Yacht Comfort Scale | PDF | Boats | Sailboats The Motion Comfort Ratio was developed by boat designer Ted Brewer to predict the comfort level of a boat based on its motion when encountering waves and swells The formula calculates a ratio that indicates the speed of upward and downward motion, with a higher ratio denoting a more comfortable ride According to the formula, as a boat's displacement increases, its motion comfort ratio will
Sailboat Design Ratios MCR = Motion Comfort Ratio MCR = DISP ( 65*BEAM 4 3 ( 7*LWL+ 3*LOA)) [ HP-41 Program] This ratio was invented by Ted Brewer who say's he dreamed it up "tongue in cheek" as a measure of the motion comfort of a boat A boat that has a more corky motion is considered less comfortable then one less affected by wave action

And if we compare that to a boat that is lighter overall, but it has a deep draft keel, with a higher ballast ratio, the bulk of the ballast carried in a bulb, its maximum beam carried to a single point in the deck so that there was less deck area near the maximum beam, a lighter weight hull, deck and interior as well as a lighter, but taller
Comfort 30 - Sailboat Guide Comfort Ratio This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness Read more Formula Comfort ratio = D ÷ ( 65 x ( 7 LWL + 3 LOA) x Beam 1 33) D: Displacement of the boat in pounds; LWL: Waterline length in feet
COMFORT 32 - sailboatdata 40 to 50 indicates a heavy bluewater boat; over 50 indicates an extremely heavy bluewater boat Comfort ratio = D ÷ ( 65 x ( 7 LWL + 3 LOA) x Beam^1 33), where displacement is expressed in pounds, and length is expressed in feet Capsize Screening Formula (CSF): Designed to determine if a boat has blue water capability
