Drilling Cooling Pickup in Rudder

Hello,

I have an older ABS v-hull that I use in a small creek/river. It is a lot of fun as the tight creek almost makes it like racing a jet boat up the river. The design of the hull keeps it very shallow, however I would like to shorten the rudder. It is using a typical TFL style rudder with the breakaway screw, and single pickup as pictured here:

Basically, I am looking for any advise on how to drill a new pickup hole higher up, so that I can shorten the rudder, as it is much longer than needed.

Thanks!

Since the hole runs up the entire back of the rudder, you could cut to your desired length and then taper the leading edge down to the trailing edge, making a bit of hook at the back.
