The recent storm that did so much\u00a0damage along the east coast of the U.S. made for an interesting evening at anchor aboard FPB 78-1\u00a0Cochise<\/em>.\u00a0With sustained gusts above 75 knots\/88mph…<\/span><\/p>\n

…the question of windage vs stability at anchor has been answered.\u00a0Check out the video below. But first, let us set the scene\u00a0for you…<\/p>\n

We have spent the weekend in Chester, MD, watching the “down rigging festival” from Cochise<\/em>. Sunday afternoon, our guests have departed, and the anchorage is now clear of visiting yachts. A couple of boat lengths away, five very traditional sailing craft sit rafted at the dock.<\/p>\n

The weather doesn’t feel right. We check NOAA on VHF. No big deal. Maybe a gale – small boats watch out – nothing for us to give a second thought. Still, we are both uneasy. We have two hours till dark. We are worried about possible flooding on the river, damage from other craft, and who knows what else.<\/p>\n

The one thing above others that gets us moving is the ease with which the dink comes aboard. Have we heard this story before?<\/p>\n

Linda gets the engines started and the electronics fired up while I get\u00a0the dink secured on the aft deck. In less than ten minutes we are headed down river, looking for a more protected anchorage.<\/p>\n

Now a word on windage and possible lifting forces associated with the various house and roof structures on the FPB 78.<\/p>\n

When Cochise<\/em> is at anchor she has neither the dynamic stability nor the restoring force of the stabilizer fins that come with speed. While we have not been worried about safety, we have wondered about comfort in a real blow at anchor.<\/p>\n

The video that follows is at night so you don’t get a sense of the motion. Essentially it was a non-issue. Yes we sailed a bit at anchor, and there was a bit of heeling in the major gusts, but not anywhere near what we would have felt with one of our sailboats in a similar situation.<\/p>\n

Enjoy the video.<\/p>\n
