From memory,this goes for both upper and lower,a-01 starts just past the corner and also takes in the corner,a-02 starts just before corner and basically all the way up the straight after that,i sat in a-02 lower last year and had a cracking view,plus there’s nice looking yachts down there aswell,which you can check outif you go for a walk along the marina Dont know if thats any help,if your looking for a specific seat,phone them up they are very helpful
