Design and Construction
The Irwin 30 Competition measures 30 feet overall, with a 26.92-foot waterline and a 10.17-foot beam. She displaces 10,000 pounds and carries 4,600 pounds of ballast. Her fin-with-skeg configuration draws a maximum of 5.33 feet. The fiberglass hull has a fin keel and a skeg-mounted rudder.
A ballast-to-displacement ratio of 46 percent and a displacement-length ratio of 228.84 put her firmly in the moderate-displacement racer class rather than at the featherweight end of the spectrum. Her sail-area-to-displacement ratio is 16.39. Paired with an oversized masthead-sloop rig, that figure points to a boat tuned for speed under sail rather than ponderous cruising comfort.
Ted Irwin founded Irwin Yachts in 1966. The company built the Irwin 30 Competition as a dedicated racing design from Irwin’s own drawing board.
Rig and Handling
A Sailboat Review account describes the Irwin 30 Competition as having an oversized rig with the standard masthead-sloop arrangement. One owner’s boat, Argo, has a tall rig, tiller steering, a mainsail stack pack, and self-tailing winches.
Owners report that the boat sails smoothly and very fast. They also describe her as well balanced, easy to control, and able to turn on a dime. With a reported sail area of 474 square feet and a hull speed near seven knots, the design rewards an attentive helm without requiring a large crew.
Argo’s Atomic 4 gasoline engine is reported to provide more than enough power to get the boat out of any bind.
Accommodations
Argo shows how the racing hull can still contain a workable daysailing interior. The saloon has a fold-out table with room for six people. Its two settees double as single berths, with storage beneath and behind them.
Forward, the V-berth sleeps one person comfortably, or two if they’re closely acquainted. Drawers and cubbies provide stowage, while a hanging locker sits beside the head and V-berth. A quarter berth aft can accommodate one sleeper or serve as a large storage bay.
The galley includes a two-burner alcohol stove, a sink, an icebox, and a 120-volt refrigerator. Plenty of galley storage is reported. The head has a flushing toilet and sink.
Equipment and Ownership
Argo illustrates the sort of equipment an owner may add over the years. Her navigation gear includes a GPS chartplotter and a backlit, gimbaled compass. She has tiller rather than wheel steering, while the mainsail stack-pack system and self-tailing winches simplify shorthanded sail handling. The Universal Atomic 4 remains the noted power plant.
Buyers and owners should expect period systems that need surveying and may require modernization, although the fiberglass shell itself is straightforward.
Known Issue
One documented ownership report identifies a small two-gallon gray-water tank. It has no pump-out, so it must be detached inside the cabin and carried by hand to a disposal point. This is a practical nuisance rather than a structural defect, but it directly affects convenience for daysailing or living aboard.
The Verdict
The Irwin 30 Competition is a purpose-built racer with enough comfort below to work as a daysailer. She carries her Ted Irwin pedigree lightly and rewards an active helm with enough performance to satisfy racing priorities. The awkward gray-water arrangement is the one documented drawback to easy use.
Pros
- A genuine racing design with an oversized masthead rig and quick, balanced handling
- Surprising comfort below for a 30-foot racer, with several berths and clever storage
- Solid fiberglass hull from a known Florida builder, with a 46 percent ballast ratio
Cons
- The gray-water tank can’t be pumped out and must be carried by hand for disposal
- The gasoline Atomic 4 and other period systems may need updating for modern use
