The Clipper Marine 21, also widely recognized as the Clipper Mark 21, is a compact and highly accessible trailerable sailboat designed by the renowned British naval architect William Crealock. Produced by Clipper Marine in California from 1971 to 1977, this fractional sloop was conceived with the primary goal of making sailing more readily available to enthusiasts, allowing owners to easily transport their vessel and explore diverse cruising grounds. It quickly established itself as a popular choice for those seeking a practical, entry-level sailboat that combined ease of handling with surprising sailing capabilities for its size.

The Clipper Marine 21 emerged during a pivotal era for fiberglass sailboat manufacturing, aligning with Clipper Marine's founding vision in 1971 to specialize in innovative, trailerable designs. William Crealock, the sole designer for the company, brought his extensive experience in offshore yacht design to this smaller, more accessible market. His philosophy for the Clipper Marine line, including the 21, centered on practicality, ease of handling, and maneuverability, allowing sailors to explore various waterways without the need for permanent dockage.

The vessel's production spanned from 1971 to 1977. Central to its design was the emphasis on trailerability, a feature facilitated by its lightweight fiberglass hull and, notably, a swing keel, allowing for a minimal draft of just 0.54 feet when retracted and a maximum draft of 4.33 feet when deployed. This made it ideal for shallow waters and easy ramp launching. During its production run, the Clipper Marine 21 was also offered in a flush deck version, providing alternative interior and deck layout options for buyers. The design incorporated innovative features for its time, such as a "one-line" uphaul/downhaul system for its kick-up rudder, simplifying operation.

Sailing Performance and Handling

Despite its compact size and focus on trailerability, the Clipper Marine 21 is often described as a surprisingly capable performer on the water. Owners frequently report that the boat handles gusts effectively and exhibits a neutral helm, contributing to a comfortable sailing experience. Its fractional sloop rig contributes to easier tacking, a desirable characteristic for cruisers and those new to sailing.

Anecdotal evidence suggests that the Clipper Marine 21 is a "surprisingly good sailing boat" that can manage well in various wind conditions. While not a performance racer, its design prioritizes ease of control and maneuverability, making it a suitable vessel for lake sailing, coastal cruising, and day trips. Its lightweight displacement of 1,800 pounds further contributes to its nimble handling.

Accommodations and Layout

The interior of the Clipper Marine 21, while modest given its 20.87-foot length overall, is generally regarded as offering considerable room for a boat of its size. The layout typically includes a V-berth forward, a small salon area, and basic galley amenities, though detailed specifics can vary, especially between the standard and flush deck versions. Owners often describe the interior as functional rather than luxurious, reflecting the boat's practical cruising ethos.

Interior finishes commonly featured wood trim, though some original elements like "yellow shag carpet" might have been present, with many owners opting for upgrades and renovations over time. Ventilation and storage are generally adequate for weekend cruising or day-sailing. While the did not specify maximum headroom, the overall layout aims to maximize usable space for its primary purpose as a compact cruiser.

Owner's Perspectives

The Clipper Marine 21 maintains a loyal owner base, with many praising its fundamental qualities. Owners consistently commend its solid construction and its ability to handle various weather conditions competently, often describing it as an "excellent boat for the price". For many, it serves as an ideal first sailboat due to its forgiving nature and ease of management. The boat's "good lines" and pleasant sailing characteristics are frequently highlighted.

However, some common points of discussion and maintenance revolve around the boat's age. Owners have noted potential issues with the original deck fittings requiring re-bedding to prevent leaks. A recurring concern, particularly with swing keel models from this era, can be related to the keel lifting system and its components, with some reports of swing keel failures if not properly maintained. Additionally, like many fiberglass boats from the 1970s, some Clipper Marine 21s may exhibit blister problems. Interiors often require renovation due to years of neglect, but owners have successfully revitalized these spaces, sometimes by reapplying finishes to interior wood components.
