Design and Construction
McGlasson’s early-sixties design pairs a solid fiberglass hull with a lead fin keel, the ballast reckoned at 47 percent of the 9,700-pound displacement — a figure higher than 79 percent of comparable sailboat designs and a strong contributor to her steady demeanor. The 10-foot beam yields a length-to-beam ratio of 3.25, making her slimmer than 54 percent of similar designs, while a displacement-length ratio of 283 places her among the “heavy cruisers” of her size, with only 38 percent of peer designs rated heavier. Her wetted surface runs about 269 square feet, and the immersion rate of 866 pounds per inch speaks to a hull that settles predictably under load.
Rig and Handling
The Islander 32 carries a masthead rig with a reference sail area of 454 square feet for mainsail and jib, and her sail-area-to-displacement ratio of 16.0 (18.9 with a 135 percent genoa) means she is faster than 42 percent of similar boats in light wind. Reviewers note she is slightly overrigged — carrying more rig than 66 percent of comparable sailboats — which suits a cruiser that benefits from extra drive. Standing and running rigging follow period dimensions: halyards for main, jib, and spinnaker each run about 85 feet at 3/8 inch, while sheets and the 81-foot mainsheet are 1/2 inch, with a 13.5-foot cunningham and 27-foot kicking strap and clew outhaul rounding out the control lines masthead rig.
Accommodations
Below, the boat is fitted with four berths, a galley, and a toilet facility — a straightforward cruising layout for a 32-foot hull of the era. The Motion Comfort Ratio of 25.5 is calculated as more comfortable than 54 percent of similar sailboat designs, a useful gauge for couples or small families weighing her against later, beamier competitors.
Performance Under Power and Sail
Under auxiliary power the Islander 32 may carry a Universal Atomic 4 gasoline inboard of 30 horsepower, giving a calculated maximum of about 6.5 knots against a theoretical hull-speed maximum of 6.7 knots. The capsize screening value of 1.88 and the comfort metrics above frame a boat built for settled coastal cruising rather than offshore surfacing of extreme ratios.
The Verdict
The Islander 32 Mk I is a tidy early-sixties McGlasson cruiser: solidly ballasted, sensibly rigged, and comfort-weighted for her length. She is not a lightweight racer, but her numbers describe a predictable, able coastal boat with period-correct accommodations.
Pros
- Lead fin keel with 47% ballast ratio, higher than 79% of similar designs
- Motion Comfort Ratio better than 54% of comparable boats
- Slightly overrigged masthead sloop with good light-air speed ranking
Cons
- Categorized as a heavy cruiser (DL 283); not a light-air flyer versus modern beamy designs
- Slimmer than average (l/b 3.25) — less interior volume than later 32-footers
- Gasoline Atomic 4 auxiliary rather than modern diesel
