Island Packet 485/525 Information, Review, Specs

Embodying the Island Packet tradition, this yacht is designed to provide a safe, stable, and comfortable platform for serious cruising sailors seeking to undertake extensive passages or live aboard for extended periods.

The Island Packet 485 began its production run in 2002, with the model subsequently being re-designated as the Island Packet 525. Designed by the company's founder, Bob Johnson, the vessel reflects his unwavering commitment to creating strong, seaworthy, and supremely cruiser-friendly yachts. Island Packet's foundational design philosophy, central to their reputation, emphasizes safety, comfort, and robust construction for extended voyaging.

A hallmark of Island Packet design, prominently featured on the 485/525, is the exclusive "Full Foil Keel®." This design integrates the keel with a protected prop and rudder, offering excellent directional stability, minimizing the risk of fouling, and providing crucial protection against impact damage—a vital consideration for offshore reliability. The hull and keel are constructed as a single piece, utilizing hand-laminated, solid fiberglass with triaxial knitted fiberglass, ensuring a strong and durable structure built for countless miles of cruising. The cutter rig, featuring a self-tacking staysail on a Hoyt boom, was incorporated to simplify sail handling and address some of the trimming challenges associated with traditional cutter rigs. Beyond the name change from 485 to 525, no other significant variations in the production run (such as MkI/MkII designations) are widely noted.

Sailing Performance and Handling

The Island Packet 485/525 is engineered for stability and comfort over outright speed, reflecting its primary role as a bluewater cruiser. With a calculated Sail Area to Displacement ratio of approximately 13.48, the yacht is classified as a heavy displacement vessel, indicating a design optimized for handling heavier winds and providing a stable motion, though it may exhibit slower performance in very light air. The Ballast to Displacement ratio, around 0.362, suggests a moderate level of stiffness, allowing the boat to stand up well to a breeze while maintaining a comfortable heel. Its Displacement to Length ratio, approximately 245.15, confirms its moderate-to-heavy displacement, typical of traditional cruising yachts that prioritize load-carrying capacity and a seakindly motion in various sea states.

Sailors often describe the Island Packet 485/525 as a "true liveaboard long-range cruiser" designed to please owners on extended voyages. While some general critiques of Island Packet designs suggest they are not optimized for fast sailing in light winds, often described as "heavy boat / light winds", the 485/525 is celebrated for its seakindliness and robust behavior, proving capable of ocean passages. The cutter rig, with its versatile sail plan, allows for adaptability across a range of wind conditions, though its overall performance emphasizes comfort and stability.

Accommodations and Layout

Entering the interior of an Island Packet 485/525, one is typically impressed by the spacious and well-appointed layout, designed for extended periods aboard. While specific headroom figures vary, the overall design prioritizes liveability and comfort. The vessel commonly features a four-cabin layout, accommodating two single berths and three double berths, alongside two heads. This arrangement often includes two main staterooms, each with its own private head and ensuite shower, providing excellent privacy and comfort for owners and guests. An additional cabin might be configured with either a berth or a dedicated desk, offering flexibility for cruising families or those who require an onboard office.

The galley is characterized by a wide, open layout, providing ample space for two or more individuals to work comfortably. Interior finishes generally reflect a quality build, with an emphasis on durable materials suitable for the marine environment. Features such as Whitewater Marine stainless-steel ports enhance the vessel's salty aesthetic while providing light and ventilation. Owners report that the boat's design incorporates numerous systems, which, while complex, contribute to its comprehensive liveaboard capabilities.

Owner's Perspectives

Owners of the Island Packet 485/525 frequently praise its solid construction and the comfortable motion it provides in a seaway, affirming its reputation as a highly capable and safe bluewater cruiser. The active and supportive owner community, fostered by resources like IP Home Port and the Official Island Packet Yacht Owners Association, is often highlighted as a significant benefit, providing a wealth of shared knowledge and assistance 5, 14, Builder Article. The spacious and well-thought-out interior is consistently lauded for its liveaboard suitability and comfort on long passages.

However, some common considerations for older Island Packet models, which may also apply to the 485/525 as it ages, include the potential for original deck fittings to develop leaks, sometimes necessitating re-bedding. There have also been mentions of concerns regarding electrical failures over time and, in rare instances, issues such as fiberglass rot or keel separation, though these are not universally reported as widespread design flaws but rather age-related maintenance items. While the boat's performance in very light winds is acknowledged by some owners as less exhilarating than more performance-oriented designs, its stability, comfort, and robust build are consistently cited as primary strengths, reinforcing its appeal as a dedicated cruising platform.
