Been there, they're not good instructors or sailors
A number of years ago (10 years?), shortly after Practical Sailor gave them a top two rating, I took their "couples" course with my girlfriend at the time. I already knew how to sail, but all my experience was on smaller boats (max 22'), and my girlfried had no experience. We spent 5 days living on board an ODay 32 with the instructor on the Chesapeake. I learned very little. A bit about navigation, but I could have learned that all in a couple of hours with a good navigation book and some practice. Other than that, the course was a waste for me (nice sailing tho, went to St. Michaels!)My girlfriend learned more of course, but a month or two later we went sailing on my dad's 22' Venture, and she wasn't able to do many basic things like raise sails, which I felt wasn't covered well as we took the course. The ODay had cockpit led lines and cabin top sheeting, when the configuration was changed, the girlfriend wasn't able to deal with it because variations hadn't been addressed.Finally, I thought the instructor was borderline competent as a boater/sailor. Two specifics still stand out to me.One was a docking manuever where she was demonstrating the "correct" technic, which involved having a dockline tied off to one of the lifeline stanchions (!) and motoring against it to bring the boat along side the dock. As the manuever went bad, to "fix" it, she just throttled up, and the boat came penduluming around that dock line and crashed broadside into the dock. (It was quite dramatic; I was impressed with the sturdiness of the ODay to survive; it didn't have the stanchion ripped of or the hull cracked!)The other was teaching us how to make a bowline, which she made up "sideways" (I don't know how to describe it...the rabbit didn't run around the standing part of the line, but instead around the other branch of the loop). I spent a good deal of time trying to get her to tie it right, and more importantly to show my girlfriend right, but she never believed me, and in the end, of course, the girlfriend couldn't tie a bowline.Since then, Practical Sailor has given them rather bad reviews as well.
