When leaving the dock the next morning at 6:10 am, we were on the middle face dock, we went aground about 30 feet off the dock. Extremely disappointed no one advised us of this when we arrived the previous day. I had to inch us off slowly to deep water, it was a hard grounding not mud or sand. I will be checking my props and gutless bearings when I do a haul out inspection. My recommendation, do not use this marina!
