Drilling the knees which support the transom

I am considering drilling the knees which support the transom of my Valiant Dr490. The purpose is to support the second leg of the A Frame (I want to strenghten the frame from a single to a double). I plann to recess the bolt head so it does not come in contact with the tubes.

I am wondering the following
1) is the knee a solid peice of timber or is it just boxed out and fibreglassed.?
2) What is the likley way that the knee has been constructed?
3) what are the down sides to drilling a 8 mm hole in the knee?

Any other thought are welcome.

TSM
