As long as your standing rigging is properly adjusted, well.....OK, as long as it is tight enough that the mast does not move side to side as the boat rocks, there should be no problem. If the rig is lose enough that the shrouds go loose as she rocks at the mooring (NOT under sail, just sitting there with no one aboard) then suddenly go tight as the boat rolls back the other way.... then you WILL have problems.... but then I think we all know that already <GRIN!>
The previous owner of my boat (keel-stepped mast) did not secure the locknuts on the turnbuckles one year, and as the boat rocked and rolled on the mooring the rigging gradually loosened. The shock loading on the rigging as she rolled eventually snapped one of the shrouds (original 3/32" wire), That was one reason that my boat has the upgraded 1/8" wire.
I have kept my boat on a semi-protected mooring for 20 years, previous owner had her there for 9 years, she has stayed upright with no problems. I haul out if a major storm threatens, and at least remove the boom and covered sail along with the outboard for less major storms, If I can't get her out for a major storm I unstep the mast (and bring it ashore) and double the line on the mooring. During Hurricane "Gloria" In 1985 there was another DS II In a local harbor that was flipped over by the wind and waves. (This was a 1985 model) The hinged mast on that boat tore of one of the chainplates, destroyed the tabernacle/hinge ,and bent the mast. However, only cosmetic damage to top of cuddy. The keel-stepped mast on my boat might have (near 100% certainty) ripped up the cuddy top and likely caused damage inside as well. One of many reasons that I unstep my mast for major storm if I can't get boat out of water in time.
