The development of fiberglass boats freed the yachtsman from much of the care and maintenance previously required. Marine windows followed the same path. Go Industries, founded in 1971 by a group of California yachtsmen, pioneered the vinyl-framed marine window - a design built to resist corrosion, require minimal upkeep, and last decades at sea. That craft continued under Mark Plastics for 35 years, and in 2023 Maritech Industries acquired the operation - the same shop, the same methods, the same commitment. Today we manufacture standard and custom vinyl-framed marine windows for sail and power vessels, built the same way they always have been.
