Swinging at anchor

[Miss Jamey Lynn]

at Anchorage 10 to 15 mile an hour winds watching a 60 ft plus motor yacht swinging in the wind next to a 53-foot Hatteras motor yacht hardly moving not sure why that's happening seen this before just was looking for ideas why that would happen just curious why boats can swing so much

Yes some boats swing a lot more than others. Hull shape has a lot to do with it and when you look at the hull shape on the classic hatteras (53,58 etc) between the keel and the sharp entry you can see it create more sideways resistance in the water. The 84 lazzara i run is definitely a swinger... I have to take this into account in busy anchorages especially around sailboats that don’t swing much due to their keels

So swingers should hang out with other swingers and non-swingers with other non-swingers? Asking for a friend.

[johnjen50]

Definitely. The non swingers get a little uptight in the presence of swingers.

It's a combination of 3 things: weight, rode length, and the ratio of freeboard to hull below the waterline. Hatts are generally heavier and have a lower ratio of freeboard to hull below the waterline.
