I had a full bankhardt surgery on March 30 and actually first got into my boat 2 months later on Memorial Day. My doctor certainly wasn't aware of this, he didn't "clear" me for easy boating(classII) for another month, but I knew my shoulder felt well enough to do some easy class 2 flat water. I just did some simple, straight-forward paddle strokes that seemed quite similar to a lot of the PT exercises I was doing with the bungees. It was great just to get on the water and was extremely carefull with my hand/arm placement, making sure not to let my hands get behind me. After 4 months of rehab/PT, he cleared me for boating and I was able to jump into III-IV water, feeling about 90-95%. I was timid while paddling for about another month or so and paid extra attention to my hand placement on all my rolls and while playing. It wasn't until after about 8 months that I truely felt 100%. Those last few percentages take a while to come back.
