About the TANZER 8.5
The Tanzer 8.5 is a 27.92 ft masthead sloop designed by Johann Tanzer and built by Tanzer Industries Ltd. in Canada, with production records indicating a single build year of 1978. This vessel represents a specific era of Canadian boatbuilding, characterized by a displacement of 7400.0 lb and a beam of 9.5 ft, offering a balance of performance and comfort for its time.
- Best for:
- This boat is best suited for coastal cruisers and weekend sailors who prioritize a responsive, performance-oriented hull form, as indicated by its SA/D ratio of 14.33 and Comfort ratio of 22.8. It appeals to owners willing to undertake significant mechanical and structural maintenance, given the high frequency of reported issues with rudders, shafts, and deck cores.
- Bluewater capability:
- With a Capsize ratio of 1.95 and a D/L ratio of 246.6, the Tanzer 8.5 is designed for coastal cruising rather than extended bluewater passages, as its relatively light displacement and fin keel prioritize speed over heavy-weather stability. While capable of offshore passages with careful preparation, the critical frequency of rudder/shaft failures and deck core moisture issues necessitates rigorous pre-voyage inspections.
- Comparables:
- Comparable boats include the Pearson 28 and the O'Day 27, which share similar dimensions, displacement, and the masthead sloop rig configuration typical of late-1970s performance cruisers. These vessels offer similar interior volumes and sailing characteristics, making them direct competitors in the used market for owners seeking a 27-foot trailerable or coastal cruiser.
