Stern light is original. Has small screw down at base, loosen it and it telescopes up, then tighten it back down into place.
Open bow sure is handy for beach or docking like you say. This windshield will actually tilt all the way back behind you so you have access to the bow. We never do that as don't intent to try and climb/walk across it... doesn't appear to be that sturdy to me and don't want to damage anything. But can definitely grab things easier, ropes, etc.
Noise level... don't really notice much of a difference with or without the top on. Engine is ear shot away regardless and it's pretty open even with top on.
It does make it difficult to climb into drivers or passengers seat... you have to kind of crawl in and out. I try not to ever put a knee or hand directly/firmly down into the original upholstery. It's decently pliable, and I condition it all the time, but I think would be easy to pop a seam if not careful. Heck its 57 years old. We use seat cushions and I give instructions for anyone that goes with us what they should/should not do. lol
