About the Schock 25 Sailboat

Designed by W.D. Schock Corporation, a California builder with a long reputation for producing capable and accessible sailboats, the Schock 25 is a compact daysailer and coastal cruiser that reflects the practical sensibilities the brand became known for along the West Coast. Built for sailors who want a responsive, manageable boat without the complexity of a larger vessel, it fits comfortably into the category of weekend and near-shore sailing. The Schock 25 carries the hallmarks typical of production boats from this era and builder — a hull shape balanced for reasonable performance and stability, making it approachable for newer sailors while still offering enough liveliness to satisfy more experienced hands. It works well for harbor sailing, bay cruising, and calm coastal passages where simplicity and ease of handling are valued over offshore capability. For those researching a first keelboat or an affordable daysailer with a reputable name behind it, the Schock 25 represents a sensible choice. Prospective buyers are encouraged to seek out a thorough survey, as detailed specifications can vary between individual boats depending on age and any modifications made over the years.
