Super knowledgeable and awesome instructors.

I took the 101 course with Trevon Baker and 103 with John Barlow. They were super knowledgeable and awesome instructors. I had zero experience and now I am absolutely hooked! I can’t wait to buy my own sailboat and will be taking the 104 class as soon as I can.

Wild Horse Island State Park Sailboat Charter

We took a charter sail out with Captain Genevieve. She was safety conscious, encouraging and enjoyed our conversation. The water and wind was perfect. Flathead Lake is a beautiful lake. Dayton is a quiet get away from the tourist areas.

Professional ASA instructor and good to learn from

Captain Genevieve is absolutely phenomenal in her knowledge and how readily she shares her insight. My husband and I want to build more confidence and skills in sailing our boat and asked Captain Genevieve to help us. She provided us an incredible lesson. She carefully listened to us for what we wanted out of the lesson. During the lesson, she offered direction and helpful hints, We love Go Sail Flathead Lake and highly recommend it.

Truly incredible experience

This was a truly incredible experience. The team made the learning fun, effective and helped the knowledge stick. Our second course in particular, 103 with Jon Barlow, left me feeling confident I could charter my own keelboat and not leave it at the bottom of a bay somewhere. Jon is a great instructor and had a manner of ensuring you were comfortable with being effective on the water. If you do the 101, definitely follow with the 103.

Excellent Private Charter with a Captain

We wanted to try something different and unique and selected this wonderful sailing experience on Flathead Lake. Our charter captain for our afternoon trip was a lovely, charming lady who has sailed all over the World on all kinds of boats and she made this trip perfect for us with his interesting travel stories. Very safety conscious and as much (or as little) time for us to practice sailing techniques. The lake is still a little cold for me right now, but we were also offered the option to take a dip and swim in the lake if we wanted. We would highly recommend Captained Sailing Charter this experience especially if celebrating a special occasion as we were welcome to bring our own cooler with adult beverages.
