I would suggest getting ALL the weight you have as far in the back corner you are aurfing as possible, before you even start just floating there the boat should be leaning to the surf side, my boats totally different than yours but ive had lots of boats and the swim grid is always at least a few inches under the water on the surf side.
From my personal experience i always get the weight in the rear corner first and get the wave tall, then once you get that you can play around mostly by adding more weight to that side but further forward to stretch the wake out so you have a longer pocket.
