In terms of size, the 1979 Irwin 25 measures 7.62m (25.0ft) overall with a beam of 2.59m, compared to the Hunter 27 at 8.23m (27.0ft) with a 2.79m beam. The Hunter 27 is 0.61m longer than the 1979 Irwin 25. The Hunter 27 displaces approximately 22% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1979 Irwin 25 has moderate sail power suitable for relaxed cruising with an SA/D ratio of 16.30 and 25.8 m² of sail area. The Hunter 27, with an SA/D of 18.23 and 33.0 m² of canvas, offers good sail power for versatile performance. The Hunter 27 has the edge in terms of raw sailing performance.

For comfort and safety, the 1979 Irwin 25 offers a moderate motion comfort level (comfort ratio: 20.6) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.82). The Hunter 27 has a comfort ratio of 17.0 and a capsize screening value of 0.82. The ballast ratios are 40.0% for the 1979 Irwin 25 and 36.4% for the Hunter 27, reflecting their respective approaches to stability.

Below deck, the 1979 Irwin 25 provides 5 berths in 1 cabin with 38L of water capacity and 30L of fuel. The Hunter 27 offers 5 berths in 1 cabin with 68L water and 45L fuel capacity.

Verdict

For cruising: The 1979 Irwin 25 is the better choice for comfortable cruising thanks to its higher comfort ratio, offering a gentler motion at sea that crews will appreciate on longer passages.

For racing: The Hunter 27 has the performance advantage with its superior SA/D ratio, meaning more sail power relative to its displacement for competitive sailing.

For liveaboard: Both boats provide similar accommodation, making either a viable choice for living aboard. Consider water and fuel capacity for extended stays away from marinas.
