It is important to locate the hole so there is nothing important behind it.  Drilling a hole into electrical or plumbing equipment would be a bad idea.

Drilling through tape helps to prevent the gelcoat from cracking.  The video below also demonstrates how to chamfer the hole to help the hole keep it’s integrity and keep the gelcoat from cracking.
