Just spent a week on the upper Chesapeake Bay. Spent time around Havre de Grace, North East, Bohemia River, and ended up in the Chesapeake and Delaware Canal on the weekend for the annual Canal Day event (renamed Canal Fest this year) in Chesapeake City. This is a very wild event akin to Marti gras on the water and yes there are alot of beads flying and bikini tops "repositioning".
All this was great until Friday about midnight. Picture well over 100 boats rafted together in a small basin when a storm hits with up to 80 knot straight line winds

Most boats had anchors out both bow and stern and not one boat stayed in place. My group of about 8 boats (mine was one of the smaller ones) rotated about 90 degrees and moved 50 yards. Anchor lines were getting tangled in props and moving the boats more. The closest I saw was when we came about 5 feet from a really large catamaran. What a wild half hour. Am not aware of any damage other than snagged anchor lines and spun prop hubs (mine

). Oh, some people had a great time tracking down thier tenders

.
One of the best hysterical lines I heard from the boat next to me was that we should jump in the water to save ourselves. Seems akin to getting out of the car during a pileup on the highway
The spun hub made for a quiet and scenic trip back to Elk Neck State Park. Within a mile or so of the Chesapeake City basin, saw at least 13 of the really big houses on the water crushed by large trees. Many trees also down in the park.
BTW - not meaning to ignite an old spirited discusion, but the anchor I saw that held the best was my 7 pound Fortress FX-11 anchor. I was so impressed, I have already ordered a second as my spare.
