Good points, Rothko.
You described my issues with the naval battle better than I could - the entire thing was just very "c'mon, gimmee a break". They just showed up outta the blue, completely unnoticed in the middle of the ocean in the middle of the night, found the right boat in one shot, etc. The whole thing was just very silly to me.
Do we have any resident eunuch experts that could help shed some light on Greyworm's situation?
