Hi mate, dont want to make you sick but i have had 11 sizable bass here on the iow this year
A few tactics i have used for a few years have i am sure helped me no end.
I fish 10 to 20 foot from waters edge.i keep very very quiet and do not use a tilley or shine my headlamp on the water! nice big chunks of maccy are the biz!
Give it a try,this seems to work on any type of beach
Remember the bass swim very close to the beach every night so something out of the ordinary will spook them.....pretend you are not there,keep very quiet.
let me know how you get on.
