Bota house build

I have a house on a small lake. A seawall of poured concrete 8 inches thick keeps the dirt in place and when it was installed a boat slip approx. 16' X 14' was made. I want to cover the slip with a wooden frame boat house. The sides will be either open or covered in lattice.
The question I am cogitating on is how to attach the 6X6 support posts to the seawall top. I first thought of using wedge anchors and L brackets but saw some supposed very strong adhesives that might work in junction with a stand-off bracket -Simpson Strong Tie ABU66Z Z-MAX Uplift Post Base- to keep the posts clear of the concrete aand moisture..
Anybody use these new adhesives and have an opinion as to the suitability for my application?
Thanks for any help.
