About the Tiger 25 Westerly Sailboat

Produced by the well-regarded British builder Westerly Marine, the Tiger 25 is a compact cruising sailboat that reflects the practical, seaworthy design philosophy that made Westerly a trusted name among weekend sailors and coastal cruisers throughout the latter half of the twentieth century. Built for the kind of sailor who values reliability and ease of handling over outright performance, this boat is well suited to coastal passages, estuary sailing, and relaxed family cruising in sheltered to semi-exposed waters. Westerly boats earned a strong reputation for solid construction and sensible layouts, and the Tiger 25 is generally consistent with that heritage. Its modest size makes it approachable for newer sailors while still offering enough capability for experienced hands looking for a manageable bluewater daysailer or weekender. Storage, stability, and a practical cockpit arrangement are typically among the strengths associated with Westerly designs of this era. While detailed specifications for the Tiger 25 are limited, its enduring presence in the used boat market speaks to its durability and the loyalty it inspires among owners who appreciate a no-nonsense British cruiser with genuine seakeeping ability.
