Temperature on land was in the upper 90's, but was considerably cooler on the water. Crew was Kelly and Michelle. The first half hour was rough, with the wind dying several times as we baked in the heat. Once we reached Canton, it picked up a bit, and it picked up considerably once we reached Fort McHenry. I handed the helm over to Kelly, who tacked toward the Key Bridge, getting us about halfway there before it was time to head back. Michelle handled much of the downwind leg back to Fort McHenry, but lost confidence and handed the helm back over to me. I took us back to Canton, where, Kelly took the helm again and practiced a few MOBs, then handed the helm over to Michelle to take us through Northwest Harbor. Approaching the Inner Harbot, we encountered traffic, so I took over the helm to get us through it, then performed a MOB myself before handing the helm back over to Kelly, who executed one perfectly. I then guided her through performing a downwind docking back into our slip.
