We went there by boat about a year ago. A few days before springs with 4 foot draft and left grooves in the mud for the last 50 yards or so to the quay. Well marked so you shouldn't have too much trouble on 3 foot draft.
<hr width=100% size=1>Better to keep one's mouth shut and be considered a fool than open it and remove all possible doubt.
Took the Mooses one Friday evening and arrived at 21:25. Bar lady says we have to order food before 21:30 so started to order. Then talked to chef and all she would do was fish and chips. This was a disappointment because Moose way paying!
Subsequently went with family on a Sunday evening. Service was poor and food was mediocre, e.g. I shared the seafood platter (for 2) and although quantity was good, it was uninspiring and crab was distinctly 'offish'.
Despite this it is a nice spot and better than the Jolly Sailor on the Hamble.
Getting in and out can be interesting with a careful check on the tides being essential. As stated the last 20 yds to the quay are particualrly shallow.
