^^ How much did you have to modify the hole in the bow to get the new nav light to fit? Was it a pretty big difference? I just don't want to chance the fiberglass getting stress fractures
BTW, thanks for the link!!!
You have to make a hole, a really big hole as seen by the below pics! If done correctly you'll have no issues. The 'glass on the bow is thick, probably 3/4" if not more and there's really no stress there.
