About the IRWIN 65/68
LOA w/bowsprit: 72.0' Thanks to '7THHEAVEN' for providing corrections.
The Irwin 65/68 is a substantial cruising ketch designed by Ted Irwin and built by Irwin Yachts (USA) in 1981. With a production run of only one year and an unknown total hull count, this vessel represents a rare, large-displacement offering from the early 1980s.
- Best for:
- This boat is best suited for experienced offshore cruisers seeking a heavy-displacement, stable platform for long-range voyaging, particularly those who value the balance and ease of handling provided by a staysail ketch rig.
- Bluewater capability:
- With a displacement of 78500.0 lb and a capsize ratio of 1.62, the Irwin 65/68 exhibits strong offshore stability and seakeeping abilities typical of heavy-displacement ketches.
- Comparables:
- Comparable vessels include the Tartan 4300 and the Hallberg-Rassy 43, as they share similar heavy-displacement characteristics and ketch configurations aimed at serious bluewater cruising.
