Design Brief & Intent
The Islander Bahama 28 was designed as an entry-level, pocket-sized coastal cruiser and club racer. In an era where builders like Catalina were finding immense success with the budget-friendly Catalina 27, and Cal Yachts was appealing to speed enthusiasts with the Cal 27, Islander aimed for a higher tier of build quality and sea-kindliness. Perry’s design prioritized stability and structural integrity, utilizing a heavy ballast package and an inward-turning hull flange. The builder targeted small families, sailing couples, and solo weekenders who wanted a boat robust enough to handle the ocean swells of the Pacific Coast, yet nimble enough to perform in light-to-moderate harbor breezes.
Stepping below deck, the interior character of the Bahama 28 reflects a step up from the utilitarian fiberglass finishes of many contemporary mass-production models. The cabin is warm, heavily lined with rich teak joinery, structural bulkheads, and custom wood cabinetry. The redesigned deck mold on the Bahama version allows nearly six feet of standing headroom in the saloon. Its layout is open and practical: a traditional V-berth forward is followed by a private head compartment with a marine toilet and sink. In the main saloon, opposing settees provide comfortable seating for four, with the starboard settee pulling out to form a double berth. A starboard quarter berth lies tucked aft, while the portside features a compact, functional L-shaped galley positioned near the companionway for optimal ventilation.
Variations & Configurations
While the hull lines remained identical throughout its production, the Islander Bahama 28 featured a few notable equipment options. The standard masthead sloop configuration features a deck-stepped mast supported by a heavy compression post tied directly to the main bulkhead. The underwater profile is dominated by a deep, high-aspect fin keel drawing five feet, though a shoal-draft keel was also offered to appeal to sailors in thin-water destinations.
The most significant upgrade for the 1981–1985 Bahama run was in the engine compartment. While older versions of the hull from the 1970s often relied on gasoline engines like the Atomic 4 or the OMC Zephyr, the Bahama 28 came standard with a modern, reliable 14-horsepower Yanmar 2GM inboard diesel. This mechanical package provided enough torque to push the boat through heavy chop while operating with the safety and fuel economy of diesel fuel.
Sailing Performance & Handling
On the water, the Islander Bahama 28 is remarkably stable and forgiving. With a displacement of 7,000 pounds and a ballast weight of 3,000 pounds, the boat possesses an impressive ballast-to-displacement ratio of 42.86%. This translates directly to a very stiff, upright ride, allowing the boat to carry full sails well after its lighter competitors have been forced to reef.
Its moderate displacement-to-length ratio of 254.18 ensures that the hull cuts smoothly through a chop rather than bouncing over it, though it lacks the surfboard-like planning ability of modern ultra-light sportsboats.
With a sail area-to-displacement ratio of 15.78, the sail plan is conservative. In light air under five knots, the boat carries some drag due to its generous wetted surface area, requiring a large genoa to keep moving. However, once the breeze fills to ten knots or more, the boat truly wakes up, tracking straight and pointing high upwind.
The capsize screening ratio of 2.06 sits right on the edge of the traditional ocean-racing safety boundary, reminding owners that while she is incredibly secure on bays, sounds, and coastal passages, she is not designed as an extreme, blue-water offshore cruiser. Her motion comfort ratio of 21.01 confirms a lively, responsive helm feel that remains highly manageable for single-handed sailors.
Known Issues & Triage
Despite its robust build, any vessel from this era requires careful inspection of several known structural vulnerabilities. The most famous is the "Islander Smile," a hairline crack that can develop at the leading edge of the keel-to-hull joint. On boats with external lead ballast, hard groundings or the natural flexing of the fiberglass hull stub can cause the adhesive fairing compound at the joint to crack 7. While often cosmetic, a persistent smile demands that the keel bolts be inspected and re-torqued, and the joint be properly ground down, filled with epoxy, and glassed over.
The deck is constructed with a balsa core, which provides rigidity but is highly susceptible to water intrusion and rot if neglected. Soft spots are common around high-stress deck hardware, the companionway, and specifically the chainplates. Water leaking down through the chainplate deck glands will eventually rot the interior marine plywood bulkheads to which they are bolted.
Furthermore, the hull-to-deck joint on the Bahama 28 is an inward-turning flange sealed with an adhesive compound and capped with a slotted aluminum toe rail. Because this joint is secured by hundreds of stainless steel fasteners driven through aluminum, galvanic corrosion can break down the seal over decades, causing weeping leaks in the cabin. Resolving this issue requires systematically backing out the fasteners, cleaning the joint, and rebedding them in small sections.
Modernization & Upgrades
Modern owners of the Islander Bahama 28 focus their refits on improving short-handed safety and simplifying electrical systems. Many owners choose to run halyards, reefing lines, and control lines aft to the cabin top by installing deck organizers and clutches. Swapping out old, standard primary winches for modern self-tailing units significantly eases genoa trim for short-handed crews.
In the engine space, the 14-horsepower Yanmar diesel is highly regarded, but auxiliary fuel tanks from this era can suffer from sludge or corrosion. Owners frequently replace the original aluminum fuel tank and upgrade to a modern primary fuel filtration system to ensure engine reliability.
On the electrical side, the original factory wiring harnesses are often tired and corroded. Installing a modern DC breaker panel, converting cabin lighting to LEDs, and upgrading the battery banks to modern AGM or lithium-iron-phosphate (LiFePO4) systems allows the boat to easily power modern navigation electronics, low-draw autopilots, and efficient refrigeration units without relying on constant engine idling.
The Verdict
The Islander Bahama 28 stands as a highly successful refinement of one of Robert Perry's finest small-boat designs. It offers an exceptional combination of predictable, stiff sailing performance, robust West Coast fiberglass construction, and a surprisingly elegant, comfortable cabin for a 28-foot boat. For budget-conscious sailors, young families, or those looking to downsize to a low-maintenance pocket cruiser, this classic design provides enduring value and exceptional safety on the water.
Pros 3

- Generous standing headroom and a comfortable, wood-finished cabin
- Excellent upwind pointing ability and predictable handling at the helm
- Reliable and efficient standard Yanmar diesel engine
- Robust fiberglass hull capable of handling rough coastal conditions
Cons 7
- Balsa-cored decks are highly prone to soft spots and water rot if deck hardware is not rebedded
- Slotted aluminum toe rail joint is notorious for developing slow, weeping leaks over time
- Underpowered in very light airs due to a conservative sail plan and high wetted surface area
- Susceptible to the "Islander Smile" at the keel-hull joint, requiring periodic inspection of keel bolts
