Our bow rail was crushed when the mooring cover at the marina clasped. Looking for a bow rail for our Four Winns Vista 320, year is 2003. She's. in great condition
Welcome to iboats, sorry to hear about the rail.
I‘d start by asking the manufacturer if they are available.
Here‘s a site I found: https://parts.fwdealer.com/
If that doesn’t work, maybe search for a boat graveyard?
Good luck!
