The Cal 28 is a classic American sailboat known for its balanced performance and practical cruising capabilities. Designed by the prolific C. William Lapworth, the Cal 28 was first built in 1963 and was initially marketed as the "California 28." This masthead sloop, with its fin keel and spade rudder, aimed to offer a blend of comfortable accommodations and respectable sailing prowess for its size. Produced by Jensen Marine/Cal Boats in the United States and under license by Calgan Marine Ltd. in Canada, the Cal 28 became a popular choice for sailors seeking a versatile vessel for coastal cruising and club racing.

The Cal 28's production run spanned from 1963 to 1969, with a total of 347 units built. C. William Lapworth, a renowned American naval architect, was the mastermind behind the Cal 28. Lapworth was celebrated for designing numerous performance-oriented fiberglass sailboats for Cal Yachts, a company known for making popular designs accessible to a wider market. The Cal 28 was notably the first of Lapworth's designs to incorporate a spade rudder, a feature that contributes to its handling characteristics.

During this era, Calgan Marine Ltd., operating out of North Vancouver, British Columbia, played a significant role in bringing Cal designs, including the Cal 28, to the Canadian market. Founded by Al Nairne, Calgan Marine's ethos mirrored that of Jensen Marine: to produce robust and well-regarded fiberglass sailboats. The company specialized in fiberglass construction, valuing durability, ease of maintenance, and efficient production, which aligned well with the design principles of the Cal 28. While there is a later model known as the Cal 28-2 (designed by C. Raymond Hunt & Assoc.), the original Cal 28 by Lapworth stands as a distinct model from the initial production period.

Sailing Performance and Handling

The Cal 28, with its fin keel and spade rudder, offers a sailing experience characterized by a good balance of performance and stability. Its sail area to displacement ratio (SA/D) of approximately 17.08 suggests a boat that performs reasonably well in lighter winds, being responsive without being overly sensitive to every puff. The ballast to displacement ratio of around 0.36 indicates a moderately stiff vessel, capable of standing up to a decent breeze without excessive heeling. This provides a sense of security and stability for its crew. With a displacement to waterline length ratio (D/LWL) of roughly 235, the Cal 28 falls into the moderate displacement category, positioning it between lighter, pure performance boats and heavier, more traditional cruisers. This combination allows for a comfortable motion in a seaway while still offering competitive speeds.

Anecdotal reports from owners often highlight the Cal 28's ease of handling, even when short-handed. It is generally considered a capable boat that can stand up to some challenging weather, making it suitable for coastal cruising and overnight trips. The boat is reported to motor efficiently, typically achieving speeds of 5-5.5 knots at moderate RPMs.

Accommodations and Layout

While detailed interior specifications are limited, the Cal 28 is generally recognized for providing functional and comfortable accommodations for its size, making it suitable for weekending and short cruises for a couple. The interior layout typically includes a V-berth forward, a head, and a salon area. Owners often describe the interior as being well-built for a production boat of its era, with some mentioning the presence of wood trim alongside fiberglass finishes. Storage is generally considered adequate for its intended purpose, though specific details on lockers and compartments would vary by individual boat and owner modifications. Ventilation is achieved through traditional deck hatches and portlights.

Owner's Perspectives

Owners of the Cal 28 frequently praise its solid construction and comfortable motion, particularly for a boat of its size. Many appreciate its capabilities for overnighting and weekending, finding it well-suited for a couple. The ease of sailing short-handed is also a commonly mentioned strength.

However, common issues noted by owners of older Cal 28s include the potential for hull blisters, a recurring maintenance concern for fiberglass boats of this vintage. Like many classic sailboats, the condition of original deck fittings and standing rigging can be a point of attention, often requiring inspection and potential replacement due to age. Despite these potential maintenance items, the Cal 28 maintains a loyal following, with owners often undertaking restoration projects to preserve these enduring vessels.
