Norman L. Skene's(in SKENE'S ELEMENTS OF YACHT DESIGN) gives 2 methods of judging the sea-keeping and stability of a boat, methods based on statistical stability diagram of several boats.
- Firs method is called Wind pressure Coefficient Method [page 292]
- Second method is called The Dellenbaugh Angle Method [page 296]
- At page 299 there you can find a the flowing table which allows you to judge a boat's stability by analyzing the transverse metacenter GM.
