Overview
Bertram 25 Flybridge Sports Fisher – Fully Rebuilt, Turn-Key Offshore Package
This vessel is a Bertram 25 Flybridge Sports Fisher, built in Australia in the early 1980s. The boat has since undergone an extensive professional rebuild and refit, resulting in a genuine turn-key offshore fishing and family cruising package.
Over more than two years on the hardstand, this classic offshore sports fisher received comprehensive structural, mechanical, cosmetic, and electrical refurbishment, with over $80,000 invested (excluding original purchase price). All work has been completed to a high standard, with invoices available for inspection.
Renowned for its legendary offshore ride, stability, and build quality, the Bertram 25 represents a rare opportunity to own a classic sports fisher with the hard work already done.
