Irwin 43 (Tall Rig)
Description
The Irwin 43 Tall Rig (also called the Irwin 43 Mk III Tall Rig, built 1986–1989) was the high-performance flagship of the long-running Irwin 43/44 series and remains one of the best-sailing big Irwins ever produced. Sharing the same modernized center-cockpit hull as the standard 43 Mk III (LOA 45′6″ with sugar-scoop, LWL 36′6″, beam 13′8″, displacement ~26,000–27,000 lbs), it carries a deeper fin keel (6′0″ standard vs. the usual 5′0″ shoal) and a dramatically taller triple-spreader masthead rig (air draft ~62′ vs. ~58′ standard) with approximately 950–975 sq ft of working sail—pushing the SA/D into the 18.5–19.5 range compared to ~16 for the normal rig. The extra canvas, combined with the stiffer deep-keel version (ballast ~10,000 lbs), gives noticeably quicker acceleration, higher pointing, and sustained 7.5–8.5 knot passage speeds in 12–20 knots—easily the liveliest of all the 43/44 variants.
