    When I sail fast enough my boat hums.

    Does anybody know what causes it?

    As I understand it, the centerboard is the source of the harmonic resonance (vibration). Pretty common from what I have heard.

    My best speed so far is 5.8, and I have never had any hums.

    Mine does too. It's the centerboard at a certain speed, mine humms a bit and then stops as the speed picks up.
