360? Sailboat stability ratings comes into play especially MAXIMUM RANGE OF POSITIVE
STABILITY
If I understand the numbers correctly -my boat rates a 120.
Meaning in a theoretical world she can roll with the mast 30 degrees below the surface and right herself.
Most recommendations I've read place 120 as the min. number for
offshore work. Knowing my boat - my conclusion is she may survive and she may not which places her in the realm of coastal - not ocean IMO.
Having said that: based on the experience of a couple of friends: I doubt she will roll thru a 360
arc and right. Most likely she will reach her limit of "inverted" stability and right herself on the same side and very likely without the mast up.
A couple of bits of criteria at play here, namely whether a kind sea exists and the speed with which she is rolled.
If the sea keeps pushing....she may well do a 360
the issue of sails up.
I watched a J24 sink in NY harbor a few years back when she was pinned on her hear while flying a
spinnaker.
So many variables.....
There is a scene in the
movie "All is Lost" which claims a 360 roll. Besides the fact it is filled with technical flaws - go see it.
