The previous comment makes a good point and ties in with another comment from the Morgan email group:
"Everything is relative. If you read Marchaj and others yes they refer to 120d as the accepted minimum these days. But that is also dealing mainly with IOR type boats, and he notes the deep fin keel on this type of hull may be inherently usafe, in that it leads to the type of motion that can roll the boat into a broach off the top of a wave.
Since you have a full keel, not an IOR fin, the same situation doesn''t apply to you--you are inherently safer against the roll being *started* than a fin keel boat.
Ideally you would have the traditional full keel *and* a higher stability angle, but in life we compromise. I would suggest that "due diligence" accounts for a lot of the safety factor. If you take the boat across the Pacific and out of range of weathercasts, you have more risk. In the Atlantic and Caribbean, it is easier to monitor and avoid extreme weather.
I don''t think anyone would call the OI41 a dangerous boat."
Its always helpful to know the details and assumptions behind mathematical formulas!!! Without the knowledge of these background parameters its just a bunch of meaningless numbers!! My research is finished.
Respectively
