Irwin 24 Information, Review, Specs

Sailing Performance & Handling

The Irwin 24 is widely regarded as a light-air specialist, a characteristic typical of Ted Irwin’s early hull shapes which prioritized reduced wetted surface area. With a displacement of approximately 3,000 pounds and a ballast-to-displacement ratio near 27%, the boat is relatively nimble but can become "tender" (leaning easily) as the wind climbs above 15 knots. According to the original Irwin 24 Owner's Manual, the vessel was offered in both a fixed-keel configuration and a keel/centerboard version. The latter is particularly prized in shallow-water regions like the Florida Keys or the Chesapeake Bay, as it allows for a minimum draft of just 2 feet 8 inches with the board up.

On the water, the boat tracks reasonably well for a short-waterline vessel, though the tiller can become heavy if the sail plan is not balanced by reefing the mainsail early. Its PHRF (Performance Handicap Racing Fleet) rating typically hovers around 230 to 240, making it competitive against contemporary designs like the Catalina 25 or the Cal 25. The rig is a simple masthead sloop, which facilitates easy headsail changes and provides plenty of power for the hull to reach its theoretical hull speed of roughly 6 knots.

Interior Comfort & Variations

For a 24-foot boat designed in 1968, the interior layout is remarkably efficient. The cabin provides roughly 5 feet 2 inches of headroom—modest by modern standards but generous for a vintage "pocket" racer. The standard configuration includes a V-berth forward, followed by a small marine head (often a porta-potti or a compact manual pump) located under a mahogany-trimmed privacy panel. The main salon features two longitudinal settees that double as berths, and a compact galley area is typically situated near the companionway to allow for better ventilation.

Irwin produced several "siblings" and iterations on this hull length. The Irwin 23 was the direct predecessor, featuring a slightly narrower beam and a more basic interior, while the Irwin 25 served as a more "stretched" version with improved amenities for coastal cruising. Buyers should note that while the Irwin 24 was built as a production boat, Ted Irwin was known for making "on-the-fly" modifications, meaning some hulls may feature slightly different bulkhead placements or galley finishes based on the year of manufacture.

Known Issues & Buyer’s Checklist

Prospective owners should approach an Irwin 24 with the understanding that these vessels are now over 50 years old. The most critical area for inspection is the deck core; Irwin used balsa-coring in the decks which, if the hardware (stanchions, cleats, or chainplates) was not re-bedded regularly, can lead to soft spots and significant rot.

A secondary concern is the centerboard trunk on the keel/centerboard models. Over time, the pin that holds the board can wear, or the trunk itself can develop leaks. It is essential to inspect the centerboard pennant (the cable used to raise and lower the board) for fraying. Furthermore, early Irwins were known for having relatively thin fiberglass layups in non-structural areas to save weight for racing. While the hulls are generally robust, owners on community forums frequently cite the need to check for "osmotic blistering" below the waterline and to inspect the original atomic 4 inboard engines (if equipped), though many Irwin 24s have since been converted to outboard power for ease of maintenance.

Community & Resources

The primary hub for technical data and historical documentation is the Irwin Yachts corporate archive, which maintains digital copies of original brochures and manuals. Owners also find significant support through the "Irwin Sailboat Owners" groups found on major social networking platforms and niche sailing forums, where technical advice on restoring the vintage teak trim and rigging specifications is frequently exchanged.

The Verdict

The Irwin 24 is an ideal entry-level classic for the sailor who enjoys "tinkering" and appreciates a boat with a racing pedigree. While it lacks the standing headroom and luxury of modern 24-footers, its sailing characteristics and shallow draft make it a versatile choice for coastal exploration.

Pros:

• Excellent shallow-water capability (keel/centerboard version).
• Strong performance in light winds, outperforming many heavier cruisers of the same era.
• Compact and relatively easy to maintain or trailer with the right equipment.
• Strong historical lineage from a legendary American designer.

Cons:

• Prone to deck core rot and osmotic blistering if not properly maintained.
• Limited headroom and cramped quarters for extended cruising or tall sailors.
• Can feel overpowered and "tippy" in heavy weather without early reefing.
