I am replacing the original Bomars with Lewmar Ocean 60s. The old ones are functional, frames still solid and watertight, but the lenses and support arms are nearing the end. If anyone has use for them, I'll part with them cheap.
After you install the new hatches, look into OceanAir. They are finishes for the inside of the hatches. They provide either a screen or a shade or nothing at all. We have had them for years now and love them.
