Mirror Offshore Mk I Information, Review, Specs

History and Design

The Mirror Offshore Mk I began its production run in 1964, a period when Tyler Boat Co. Ltd. was at the forefront of the burgeoning fiberglass yacht market. Edward Tyler, the company's founder, had a background in construction and an early interest in fiberglass, initially using it for building materials before venturing into boat waterproofing and eventually yacht construction. Tyler Boat Co. became renowned as a master laminator, providing high-quality GRP (Glass Reinforced Plastic) hulls and decks not only for their own complete yachts but also for numerous other finishing yards worldwide. This expertise in fiberglass construction contributed to the robust build of the Mirror Offshore Mk I.

The design, Van de Stadt's "design #101," was particularly clever for its intended market, aiming to deliver a robust and appealing small cruiser. The Mk I was characterized by its triple keel configuration and a masthead sloop rig. While production of the Mk I eventually ceased, an updated Mk II version, modified by GDB Marine Ltd., later appeared in 1980, featuring a different rig and interior layout, and often a taller mast and increased sail area. The Mk I, however, maintained its distinct charm with its original specifications, including 122 square feet of reported sail area and a displacement of 1,800 pounds.

Sailing Performance and Handling

For a boat of its modest dimensions, the Mirror Offshore Mk I offers a stable and forgiving sailing experience. Its triple keel hull type contributes to its stability, making it a suitable choice for new boaters or those seeking a less demanding sail. With a reported sail area of 122 square feet and a displacement of 1,800 pounds, it is considered a moderate weight sailboat, though some characterize it as underpowered, suggesting it performs best in moderate breezes rather than light air. The hull speed is calculated at approximately 5.32 knots. Owners generally describe the Mk I as easy to handle, exhibiting a balance that belies its size. While not a performance racer, its solid construction and straightforward masthead sloop rig make for predictable handling in various coastal conditions.

Accommodations and Layout

Despite its compact size, the Mirror Offshore Mk I was cleverly designed to maximize interior space. It is notably one of the shortest production boats to feature a separate heads compartment, a significant convenience for a vessel of this length. The typical interior arrangement for the Mk I often includes two berths forward, providing basic sleeping accommodations. While specific details on finish quality and materials require closer inspection of individual boats, the builder, Tyler Boat Co. Ltd., was known for the quality of their fiberglass laminations, suggesting a solid foundational structure. Owners frequently appreciate the smart use of space for a boat under 19 feet, allowing for comfortable weekend cruising for a small crew.

Owner's Perspectives

Owners of the Mirror Offshore Mk I often praise its robust construction and surprisingly spacious interior for its size. Many value the practicality of its trailer-sailer design, allowing for easy transport and access to various cruising grounds. The triple keel design is also frequently highlighted for contributing to stability. Common sentiments suggest that while the Mk I may not be the fastest boat on the water, its reliability and ease of handling make it a beloved choice for those seeking a straightforward and enjoyable small cruiser. As with any older fiberglass boat, potential maintenance considerations often revolve around the condition of original fittings and the need for periodic refurbishments. However, the enduring community of Mirror Offshore owners underscores the lasting appeal and functional design of this classic small yacht.
