Managed to miscalculate the tide just a tiny bit last Saturday on my way back from France, and clipped a rock on the entrance to my beach mooring/harbour. Guess if I'd not bought so much wine the boat may have been riding a little higher in the water and all would have been well. Photo shows the passage I have to take (and no, the tide wasn't quite that low when I tried to return
However, the upshot is, I've burred the edge of one of the baldes (and probably left a groove in the granite). Is this likely to be enough to cause a balance issue or vibration. I'm presuming I should just lightly file the rough edge and go for a spin and see.
