AdvanTec Marine

What AdvanTec Marine does

AdvanTec Marine (legal entity: AdvanTec Manufacturing Canada Inc. and AdvanTec Manufacturing USA Inc.) is a privately held specialty manufacturer of marine closures and access equipment, headquartered in Chilliwack, British Columbia, with a second manufacturing facility in Gold Beach, Oregon. Through six wholly owned sub-brands (Freeman Marine, Diamond Sea Glaze, Steelhead Marine, Pacific Coast Marine, USA Sliding Doors, Manly Marine) and two partner brands (Ucalsa, Karaca Gemi), the company designs, engineers, and builds watertight and weathertight doors, aluminum cast and steel hatches, marine windows, and cranes and davits for commercial vessels, superyachts, military and government fleets, and selected civil engineering applications. Its product portfolio is anchored on patented quick-acting dog mechanisms and proprietary DiamondFrit glass, with both facilities holding ISO 9001, DNV welding workshop approval, and the only Canadian MED Wheel Mark certification for fire-rated (A0/A15/A30/A60) door production, plus approvals from Lloyd's Register, Bureau Veritas, ABS, and Transport Canada.

The company sells exclusively on a quote-based pricing model through a hybrid enterprise field sales and authorized distributor/dealer channel spanning 50+ countries, supported by a Naval Architects registration portal for design engineers, an online parts storefront at advantecstore.com, a Quickship expedited program, and onsite commissioning, warranty, and aftermarket service. Revenue is generated through hardware sales (custom engineered product, standard SKUs, and replacement parts) and a smaller professional services stream for maintenance, repair, and technical support. Customer concentration is anchored by defense agencies (U.S. Navy, U.S. Coast Guard, Royal Canadian Navy), top commercial shipbuilders (NASSCO-General Dynamics, Bollinger, Alabama Shipyards), and long-tenured luxury yacht relationships (Turquoise Yachts, ~30 years).

Operationally AdvanTec runs a multi-brand acquisition platform: Manly Marine was acquired in 2010, with other brands consolidated around it, and corporate structural moves since 2024-2025 include the 2025 fire-rated door dual-facility certification, a global distributor workshop for Steelhead cranes, the appointment of Jamie Munro as VP of Sales (Feb 2026), and the addition of distribution partners in Benelux (B2B Marine) and Florida (All Points Boats), alongside a Business Development Manager dedicated to Europe and South America. Leadership is anchored by President Dave Vanlaar (also VP of AdvanTec Industrial), CFO Sarah Neetz, VP Matt Kirby, and tenured operations directors in both the U.S. and Canada.

• Wärtsilä: Finnish broad-line marine systems provider spanning engines, propulsion, and ship services. Overlaps with AdvanTec through naval and commercial shipyard channels but is far larger and not specialized in closures.

Others

• Ucalsa: Spanish manufacturer of watertight and fire-rated marine doors under SOLAS Wheel Mark certification. AdvanTec Marine holds a Ucalsa license to manufacture fire-rated doors in the US and Canada, making it a licensing partner rather than a competitor.
