I bought a 33 MK II in Toronto last fall and there was a loud hum. The hum was
there on Toronto Island where I pick her up and at a marina on the mainland. I
asked the owner about it and he said "I have never heard that before" and I
thought what have I just bought myself.

Had a similar hum while coming back from Newport. The engineer on board put a

Don't listen to him, Jim. I can tell he's just
making things up. The name was Peat and we don't
have pints of rum... maybe a litre or two.
And to settle the ghost, try hoisting a fender
alongside the mast about half way up. You will be
amazed how it can settle the rig if you have

It's the ghost of Penelakut Pete. He drowned in Clam Bay when he fell
overboard after consuming a few pints of rum. Legend says he only comes
