One word (well actually one acronym) IQF. A 10lb bag isn't going to kill you space or cost wise and will go a long way towards getting those fish into the mood.
I bet you'd benefit by pulling a couple of daisy chains behind dabos/rabbits/birds and running chuggers or jet heads on your outside rods. Since you're on a small platform, maybe you need to make yourself stand out a little more to get those fish up. If it gets real desperate maybe even run a pair of diving boards off of your corners. I'd be glad to lend all of that to you if you want to give it a try.
