Go Sail Flathead Lake operates from Dayton, Montana, offering sailing instruction, rentals, and guided cruises on Flathead Lake. The company provides American Sailing Association (ASA) courses including ASA 101, 102, 103, 104, and 111, plus combo certification programs that prepare participants for bareboat chartering. Instruction is hands-on and delivered in small groups aboard a variety of sailboats, from Capri 22 keelboats to 30–45 foot sloop‑rigged cruisers used for bareboat training.
Options range from a three‑hour introductory sail and refresher courses to multi‑day certification combos. Short experiences such as the three‑hour “A No‑Stress Introduction to Sailing” and ASA 111 refresher focus on practical skills, knot work, and sailor terminology. Two‑day courses cover keelboat basics, racing skills, and bareboat cruising techniques, while four‑ and six‑day combo courses combine 101, 103, and 104 curriculum for broader certification.
Go Sail Flathead Lake also offers captain‑guided boat tours and sunset cruises that showcase Wild Horse Island and surrounding islands with opportunities for wildlife viewing. Experienced captains can tailor the experience for relaxation or informal instruction. Certified sailors can rent a Capri 22 bareboat for independent exploration, with options to add kayaking, paddleboarding, or swimming.
All offerings emphasize safety, hands‑on learning, and navigation of Flathead Lake’s consistent winds between Wild Horse Island and Big Arm Bay. Reservations, course prerequisites, and certification details are provided for each trip. Booking information, specific boat assignments, and safety briefings are available per trip; participants should review course prerequisites and prepare for on-water instruction and practical assessments before arrival and launch.
