To each their own, but having grown up camping on the shores of Sak in the New Town area where we would leave the boats beached overnight, through storms, etc for weekend's at a time, there is a real difference in wear on a glass hull when compared to the aluminum hulls.
If you are able to cherry pick your beaching spot for a shore visit, I have no issue with glass hulls on the shore. It's a Devil's in the Details kind of thing for me. And like I said, at this point the Corps has really taken that away from most boaters in ND nowadays, so even I would probably lean towards glass on my next purchase.
