Design and Construction
The Islander 30 has a solid fiberglass hull and carries 2,900 pounds of internal lead ballast within an 8,400-pound displacement. It has a fin keel—although one source describes it as a long keel—and a skeg-hung rudder.
Its 23-foot-4-inch waterline and 8-foot-10-inch beam produce a length-to-beam ratio of 3.35, making it slimmer than three-quarters of comparable designs. A displacement-length ratio of 295 places it among the heavier cruisers. Its 35 percent ballast ratio is higher than that of only about a fifth of similar boats, while its 1.74 capsize screening value would, by that formula alone, admit it to ocean racing.
The raised deck, a defining feature carried over from the Islander 29, increases headroom below. Ports and hatches bring natural light into the cabin.
Rig and Handling
The Islander 30 carries a masthead sloop rig on aluminum spars, with 355 square feet of sail between the mainsail and jib. Its SA/D is 13.8 with the reference sail and rises to 16.2 with a 135-percent genoa. That makes it quicker in light wind than roughly a quarter of its peers. However, yachtdatabase.com says the boat carries more rig than 96% of all similar sailboats, marking it as significantly overrigged.
The theoretical hull speed is 6.5 knots. A motion-comfort ratio of 28.1—more comfortable than 76 percent of similar designs—suggests a stable, if heavily canvased, coastal cruiser.
Specified running-rigging dimensions include a 75.5-foot mainsail halyard at 3/8 inch and a 74-foot mainsheet at 1/2 inch.
Accommodations
The practical interior sleeps four comfortably and uses teak trim typical of the era. A spacious V-berth fills the bow, convertible settee berths line the saloon, and a centerline head serves the cabin. The compact galley includes a gimbaled stove and an icebox.
The raised deck provides additional headroom, while ports and hatches admit natural light. Fuel and water tankage are modest, suiting short passages rather than extended offshore living.
Auxiliary Power
Auxiliary power comes from a Universal Atomic 4 gasoline inboard rated at around 30 horsepower. Together with the modest tankage, it supports the boat’s stated focus on stable coastal voyaging rather than long-range self-sufficiency.
Verdict
The Islander 30 is a compact, solidly built McGlasson design. Its raised deck, conservative ballast, comfortable motion, and accommodations for four make it a family-friendly coastal cruiser. Its overrigged sail plan, modest tankage, and brief production run, however, place it firmly in niche coastal-cruiser territory rather than among bluewater voyagers.
Pros
- Raised-deck layout provides enhanced headroom and natural light
- Solid fiberglass hull with internal lead ballast
- Comfortable motion, exceeding 76 percent of similar designs
- Family-friendly accommodations for four
Cons
- Significantly overrigged compared with its peers
- Modest tankage limits passage range
- Brief production run limits fleet size and spares commonality
