|Teak winch pad used to mount a fireplace chimney|
For my application, I drilled out a 5 inch hole with a circular drill bit, then sanded down the base of the winch pad, till the slope of the pad was complimentary to the slope of my boat deck. Then I laid down some 4200 sealant and drilled the teak pad down into the balsa core fiberglass deck of my boat. This makes for a solid, water-proof attachment. I've never seen a leak on the inside of the boat.

This is the pad I used. Looks pretty, ages well...
