Mr Twist!
I'm just warning you...you will battle for vis this time of year. At the moment all the rivers have broken into the sea and the water is a ginger-beer colour.
BUT - if you get some clean water you can get some fish! Ski boat bay is in Ramsgate. It is the next beach south from the main beach. It's very easy to shore dive...nice entry and exit bay. The point on the south side of the bay drops off quite steeply and is good for bronzies,garrick and brusher in the season. Summer...you will have to see whats swimming around. Further out the reef starts before the nets and runs southwards in 13m+. There is a good spot towards the south edge of this reef.
I am from southbroom and should be around when you are there. I'm always keen for a dive!
