The Comfort Ratio is calculated:
For example:
Step 1. Calculate the weighted length component: Multiply LWL by 0.7 and multiply LOA by 0.3 and add these two results together.
Step 2. Calculate the beam component: Raise the beam (to the power of 1.33).
Step 3. Calculate the denominator of the formula: Multiply 0.65 by the result from step 1 (weighted length). Multiply that result by the result from step 3 (beam component).
Step 4. Calculate the comfort ratio: Divide the boat’s displacement by the result from step 3.
Interpretation:
A higher number indicates a more stable comfortable vessel (while lower numbers indicate a lighter, livelier one), making the boat more suitable for offshore passages. A value of 30 or higher is often recommended for offshore sailing. However, the value is not very valid or reliable – read more.
