Bertram has long been regarded as one of the most iconic names in offshore boating, known for building some of the toughest and most capable hulls ever produced. Founded on performance and durability, Bertram's deep-V hull designs revolutionized the industry and continue to be highly respected today. Classic Bertram models remain extremely desirable for their timeless styling, solid fiberglass construction, and exceptional ride quality, making them a favorite among knowledgeable boaters and collectors alike.
The Bertram 20 Bahia Mar is a legendary small sport cruiser built on a proven deep-V hull that delivers a soft, confident ride well beyond what you would expect from a 20-foot boat. Featuring a simple and functional layout, this model offers a forward cuddy cabin for storage or overnight capability, a clean helm layout with excellent visibility, and an open cockpit that is perfect for cruising, fishing, or day use. This example has been significantly upgraded with a Volvo Penta 5.7L GXI (approx. 320 HP) paired with a duo-prop stern drive, offering strong, reliable performance and modern drivability compared to older configurations.

This particular boat stands out due to the level of investment and thoughtful upgrades completed by the current ownership. The engine package, sourced through Volvo Penta, was fully inspected and brought up to date prior to installation, and professionally installed by Northwest Diesel in Bellingham, Washington. At the same time, the stern stringers and transom were completely rebuilt, along with the installation of a new aluminum fuel tank, addressing some of the most critical structural components of the vessel.
The boat is further equipped with a full canvas enclosure and an Alaskan bulkhead, extending protection just beyond the helm seating area, making it well suited for Pacific Northwest boating in a wide range of conditions. A fresh wrap completed in 2024 and recent hull touch-ups give the boat a clean, updated appearance. The sale is driven by the owner moving into a larger vessel for cruising, presenting a strong opportunity for the next owner to step into a well-sorted and upgraded classic Bertram.
