When I get going with my 1982 Hobie 16, I will get a humming noise and at times with the humming I can feel a soft vibration through the boat itself. What is causing this and how do I get rid of it?
That is the sound of beauty and life! You want to embrace it not get rid of it!
It is your rudders - very common. You need to tune the trailing edge of the blades and remove as much slop from the rudder system as possible.
sm
the more noise you hear below water = the more flow you are vibrating/disrupting off your boards/boat (its a slow thing)
now when your going so fast your shrouds are hummin ... that's the sound of speeeeed

A chap across the bay has an H17 that hums so loud I can hear it 100 meters away. I told him to file the TRAILING edges of his rudders & boards a bit.
Do a search,on the Hobie forum, or someone post the link. I believe Matt Miller on the Hobie forum addressed this issue a few years ago.
"The hobie sound"usually when you exceed 15knots, a humm, a hobie 16 owners mantra
