Islander 30 Mk II Information, Review, Specs

History and Design

The Islander 30 Mk II entered production in 1970 and continued to be built until 1985, with approximately 500 units produced. The design of the Islander 30 Mk II is credited to American maritime architect Robert Finch, who was commissioned to create this model alongside the similar Bahama 30. While some early Islander models bore the distinctive visual imprint of their wooden predecessors, faithfully reproducing plank seams in their fiberglass molds, the 30 Mk II emerged from a later period of Islander's history, after the company had solidified its fiberglass production processes.

Islander Yachts, a company with roots in Joseph McGlasson's early boatbuilding ventures and an early offshoot of Columbia Yachts, cultivated a reputation for producing well-designed, robust cruising yachts. Their manufacturing ethos during this era focused on solid construction, a characteristic evident in the durable fiberglass hull and deck of the Islander 30 Mk II. There were variations in the Islander 30 line; the Islander 30 Mk II is distinct from the Bahama 30, though they share a hull. The Bahama 30 featured a more "modern layout" compared to the traditional Islander designs. The Islander 30 Mk II also offered a "Tall Rig" option, providing a larger sail area for potentially enhanced light-air performance.

Sailing Performance and Handling

The Islander 30 Mk II, with a total calculated sail area of 445.68 sq ft, a displacement of 8,600 lbs, and a ballast of 3,500 lbs, presents a balanced design for cruising. Her Sail Area to Displacement (SA/D) ratio of approximately 16.9 indicates a moderate sail plan relative to her weight, suggesting a boat that performs adequately in a range of conditions but may not be a dedicated light-air speedster.

With a Ballast to Displacement (B/D) ratio of around 0.407, the Islander 30 Mk II boasts a respectable amount of ballast, contributing to her inherent stiffness and stability, enabling her to stand up well to a breeze. The Displacement to Length (D/L) ratio of approximately 258.5 suggests a medium-heavy displacement cruiser, indicating a comfortable motion in a seaway and good carrying capacity, rather than a lightweight performance machine.

Anecdotal evidence from owners often praises the Islander 30 Mk II as a "very good sailing boat," described as "stiff and able." Owners have found her to be stable and fast, returning efforts with reliable performance. She is considered a capable boat for coastal cruising and weekend adventures.

Accommodations and Layout

While specific interior details are limited in provided data, the Islander 30 Mk II's accommodations are generally regarded as comfortable and functional for her size. Typical layouts for boats of this era and purpose often include a V-berth forward, a main salon with settees that may convert into berths, a galley, and an enclosed head. The interior finish usually featured wood trim, contributing to a warm and classic yacht aesthetic. Storage is generally adequate for cruising needs, and ventilation is typically achieved through deck hatches and portlights.

Owner's Perspectives

Owners of the Islander 30 Mk II frequently praise its robust construction and solid build quality, noting that the boat holds up very well over time. Many have found them to be capable vessels for coastal cruising and weekend trips. The boat has even been noted to have an extensive racing history for some individuals, coming in 5th at least once in races like Port Huron to Mackinaw. Its enduring appeal is highlighted by continued activity in online forums, where owners discuss maintenance and share their experiences.

Common areas of consideration for older vessels like the Islander 30 Mk II typically revolve around aging components, such as the original engine (often an Atomic 4 gasoline engine, which may require replacement or significant overhaul if not maintained). Potential buyers are often advised to inspect for structural issues like keel or core rot, as well as the condition of sails and rigging, which are common big-ticket items for any older sailboat. Despite these common considerations for any vintage yacht, the Islander 30 Mk II maintains a reputation for being a well-regarded and reliable cruising platform among its owners.
