Our Legacy and Mission

Since 1938, the Diamond Lake Yacht Club has been a beacon of sailing in Cass County, nurturing a love for this elegant sport among its youth. Continuing this proud tradition, the Diamond Lake Sailing School (DLSS) is dedicated to introducing and teaching the art of sailing to young enthusiasts. Our mission is not just to teach sailing but to instill a lifelong passion for this versatile sport, whether it be racing or cruising.

Sailing School Schedule

Our sailing season runs from mid-June to the beginning of August. Classes are conducted Monday through Thursday, with Friday reserved for make-up sessions in case of inclement weather. Each class is three hours long, starting at 9:00 AM and 1:00 PM. Morning sessions are typically reserved for our younger sailors, taking advantage of the gentler morning winds.

Our Approach to Learning

Sailing education at DLSS begins on dry land. Here, students get acquainted with their sailboats, learning the intricacies of rigging and boat handling. This foundational knowledge paves the way for swift progression to on-the-water training, where the real adventure begins. Our classes, capped at 10 students, ensure personalized attention with a high instructor-to-student ratio of three instructors per class. The focus is on mastering the fundamentals of sailing in a fun, engaging, and supportive environment.

Location and Facilities

DLSS proudly operates from the front of the Diamond Lake Yacht Club, located at 21268 Shore Acres in Cassopolis, MI. Our prime location includes two long docks, comprehensive facilities, ample parking, and a 100-foot-wide waterfront, offering direct access to the beautiful Diamond Lake.

Our Proud

The heart of our school is our diverse and carefully selected fleet, comprising nine Optimist sailboats (Opti's), seven Sunfish, three 420s, and a Butterfly. The Opti's, renowned as the world’s most popular single-crew instructional sailboat, form the core of our beginner training. For more advanced students, especially those eyeing high school and college sailing, we utilize the 420s – double-crewed sailboats that offer a more challenging and collaborative sailing experience.
