What’s that noise

[PConti2025]

I have a 15 foot Spindrift Rascal. Today was my last sail of the season. When I am sailing close hauled in 10 mph wind I hear a humming sound while boat travel through the water. What is that humming sound coming from

I am not familiar with the boat but if it has a cable controlled centerboard that would be where the vibration can come from.

Probably the centerboard vibrating.

Yes tge centerboard.vibrating makes sense. There is no cable just an uphaul line. I tried to attach downhaul line but groove on forward side of centerboard is too shallow and line get hung up. I depend on weight of centerboard to lower boat as my sail speed picks up I imagine the centerboard is being retracted by forward movement

I love that hummmmmmm... Its like the boat is singing to you.

As already mentioned, it is the dagger board.

Your boat is singing while doing it's happy dance. It becomes addicting after a while. You kind of miss it when it's gone.

However, if you want to get rid of it, loosen your centerboard line

We can judge our speed by the hummm now. When the sound comes, we’re smiling.

I used to race on a flying tiger 10-meter.
When we would get it up on a plane with the spinnaker, it had quite the hum.
For us, that was the sound of speed and quite pleasant.

Agree to all I am becoming quite fond of that sound

Reminds me of a Neil Diamond lyric .. "...like a guitar humming..." I don't think he was singing about a centerboard ...
