Use a hole saw.

A couple of things to worry about (we'll think of more):
Look carefull at what you might drill into- wiring, piping, a tank, finish
work, etc. It's easier to pull a wire harness aside than to re-splice it.

Determine if the deck is cored. If it's over 1/4" thick, it is, and you
need to seal the core. Depending on what the core material is, techniques
vary.

I friend of mine is bringing over his boat so we can drill 1 1/8inch holes
in his boat for pole holders.

This is a boring ol' fiberglass boat, but I figured I'd post a question to
you experts for some suggestions to make sure it goes well.

Could you give us any suggestions/warnings/hints about drilling into
fiberglass to make sure it goes well.

Any help would be greatly appreciated.

Thank you, from a novice boat builder
