Maritech Industries

Maritech Industries Inc. manufactures custom vinyl-framed marine windows in Corona, California, for sail and power vessels. The company’s roots trace to Go Industries, founded in 1971 by California yachtsmen to create durable, low-maintenance windows for fiberglass boats. The operation continued under Mark Plastics for 35 years before Maritech acquired it in 2023, carrying forward its established methods and commitment to marine window manufacturing.

Maritech offers fixed, sliding, hinged, and removable windows for refits and new construction. Products can be made to match existing openings or customer-provided dimensions and radiuses, with frame profiles and pane materials selected for marine use. High-impact, weather-resistant vinyl frames resist corrosion and many common marine chemicals, while installation features such as pre-drilled frames, interior trim rings, and stainless steel fasteners support clamp-style fitting. Sliding models include handles designed to stay secure, oversized drain holes, and an interior splash guard. Hinged windows use stainless steel adjusters and screw-down dogs for sealing. Customers can contact the company to discuss custom orders or request a replacement quote.
