When attaching just about anything to your boat with screw you should use self-tapping screws and DO NOT DRILL a hole. If you need a starting hole to keep your screw from wandering, use an awl to make a hole for the screw point. The only time you should drill a hole for screws if if you are using an anchor for a heavier load.
A plastic welder makes for an easy fix to any mistakes.
Triumph has a maintenance page on their website and they have more information on this.
