[quote=motivated]My old Hobie (pictured here in 1975) would make this very erie singing sound when the boat was on a certain tack at a certain speed. The hulls would resonate. On one occasion, it attracted dolphins who came up alongside the boat, they swam directly under me while I was hiking out. Very cool. That was well over 30 years ago. Do the newer Hobies still make this sound? Has anyone else experienced this phenomenon?[/quote]
