portlites
The originals were Beckson. You can talk directly with the folks at Beckson (beckson.com) and you'll find them very helpful. If the frames are OK you can get replacement lenses only - you shouldn't have to replace the frame. If you do opt to replace the whole thing you will likely have trouble getting off white color and will have to settle for white but call them and see. I opted to replace mine with Lewmar with aluminum frames. Expensive but very nice. No flange sticking out to wack your ankle or break. The cutout for Lewmar is larger but the outside of the frame dimensions are identical so they look perfect.When you remove the ports you'll find the liner and deck are two seperate pieces with just an air gap between so it's tough to make a tight seal and any leak allows water into the gap and eventually into the core - not good. I filled in the gap with epoxy mush - made a very solid fit and seal.Good luck!
