Technical Articles

Here’s where I’ve posted information about some of the more common technical issues we run into while solving yacht vibration problems.  I’ve done so in hopes they might provide some helpful background information for you in your quest for success in dealing with your own yacht vibration and running gear issues. If you are just starting out, get a great overview by reading “So you’ve bent the props… Now What?”

The problem is I don’t know if the technical questions I’ve selected are those you might consider to be the most helpful. It would be great if you posted a comment asking for more clarification on something that puzzles or intrigues you that you’d like me to talk about in a post or as a longer technical article.

Also, if there’s another site that you believe has as good information—or even makes a good case for contradicting my point of view—feel free to link to it in your comments so we can share it with others and so I might either learn from it or have an appropriate response to it.

This is one of the best ways I know to expose you to enough facts so you can make up your own mind about the right company to do  your work.
