Rosborough 246 Yarmouth

From 1987

The Rosborough RF-246 Yarmouth / current cruising layout is a Nova Scotia-designed compact semi-displacement cruiser/workboat derivative built around an 8-foot-6-inch trailerable beam. The RF-246 has appeared with materially different interior layouts and propulsion packages over its long production history, so exact engine, tank and accommodation details must be matched to the individual build.

Best for

  • Couples wanting a compact all-weather coastal cruiser
  • Owners needing trailerable beam with more displacement and workboat character than a light pilothouse boat
  • Cruising, fishing or mixed-use operation

Trade-offs

  • Narrow beam limits side-deck and interior volume
  • Long production history creates substantial variation in engines, tanks and layouts
  • Utilitarian finish and workboat ergonomics may feel basic compared with modern cruisers

Known concerns

  • No model-specific concern has been promoted to B-Atlas’s evidence threshold. This does not mean the model has no age-, condition- or hull-specific risks.

Inspection focus

  • Confirm exact builder, year, layout and propulsion package
  • Inspect hull/deck structure, wheelhouse joints and previous hardware penetrations
  • Inspect engine/outboard installation, fuel system and steering
  • Verify actual tank capacities, loaded weight and trailer suitability

About this record

B-Atlas preserves uncertainty: missing information remains unknown rather than being treated as a negative. Specifications and guidance describe the model record; individual boats can differ by year, equipment, refit and condition.
