The Invader 22 is a compact and versatile monohull sailboat, introduced in 1975 by the prolific British builder, Thames Marine. Derived from the popular Snapdragon 670, this 22-foot vessel was designed as a capable cruiser-racer, offering a balance of performance and comfortable accommodations for its size. Known for its robust fiberglass construction and practical design, the Invader 22 quickly gained a reputation as a "great little ship" suitable for coastal cruising and as an accessible option for small families and first-time boat owners.

The Invader 22 was conceived in the mid-1970s, designed by David Feltham in collaboration with Thames Marine founders Walsh and Wakefield. Thames Marine, initially known as Thames Structural Plastics, had established itself by embracing fiberglass technology, producing practical, sturdy, and family-friendly cruising yachts. Their design philosophy focused on creating accessible and comfortable boats well-suited for the often-shallow waters around the UK, frequently incorporating twin or triple keels to allow for safe drying out in tidal berths. While the Invader 22 was primarily offered with a fin keel, bilge keel versions were also available, enhancing its versatility for various sailing grounds. The company's in-house design expertise and efficient fiberglass construction were hallmarks of their approach during this era.
Sailing Performance and Handling
While traditional performance ratios are not typically applied to boats of this size, the Invader 22 is characterized as a light displacement vessel compared to many similar designs. Equipped with a masthead sloop rig, she was designed to deliver good sailing performance for a cruiser of her length. Owners have often praised the Invader 22 as a capable and enjoyable boat to sail, proving herself a "great little ship" in various conditions. However, some owner feedback suggests that she may become more challenging to handle in winds exceeding Force 5-6. The design incorporates a fin keel, contributing to her upwind ability and general stability.
Accommodations and Layout
Despite its modest 22-foot length, the Invader 22 was designed to maximize interior volume, offering accommodations for up to five individuals within a two-cabin layout. The saloon typically features a dinette on the port side, capable of seating four. A separate heads compartment adds to the comfort and practicality of the vessel. The interior often benefits from full internal mouldings, contributing to a clean, bright, and easily maintained living space. Standard amenities found on some models include a toilet, a hob for cooking, a VHF radio, and a dining table. The boat was originally configured for an outboard engine, though an inboard engine installation is feasible, with a 4hp outboard considered sufficient for propulsion, and a 6hp recommended for more robust performance.
Owner's Perspectives
Owners generally regard the Invader 22 as a "solidly built little cruiser with good accommodation for her era". Many report having "no real problems" with the boat itself. The enduring appeal of Thames Marine's vessels, including the Invader 22, is underscored by a vibrant community of owners. Associations such as the Snapdragon Mirage and Invaders Association provide a platform for enthusiasts to share knowledge, find parts, and connect, highlighting the lasting impact of these classic British yachts. While the boats are generally robust, some owners have noted common maintenance issues, particularly relating to engine problems, which are often associated with older outboard motors or neglected inboard units. These are typically manageable issues that do not detract from the overall positive ownership experience.
