15’ - 18’ outriggers would work well for your size boat. There are fixed and collapsible versions, I think most people go for collapsible to make them easier to store. On the fixed versions you can get internal rigging to tidy things up, but it seems like it would be a nightmare if you had to do any repairs or re-rigging, especially out on the water.
Mount the bases relatively close to the rear corners of your hardtop - about 6” - 12” in from the outside edge and 1’ - 3’ forward depending on what makes the best fit. I’d recommend ones that have a handle that allows you at least swivel them into position from underneath. Some allow you to adjust the height from underneath as, but that you’ll probably find you’ll set it once and leave it.
Taco Marine makes basic to mid level bases and outriggers, Gemlux and Rupp are mid level and up. Marsh Tacky makes high end outriggers only. You can mix and match bases and outriggers, just make sure that base and outrigger butt section are the matching size.
Note you will also need to think about where you are going to place your halyard tensioners. This is usually slightly aft of where the bases are mounted and on the top of the gunnel. Needs to somewhere easily accessible as this is where you will be operating the riggers from. Gemlux makes a suction mount if you have a smooth surface that will work and you want something removable.
Another consideration is rod holder configuration - which ones you will be using for the outriggers and which will be used for running rods straight to the gear. On my boat (30’ Pursuit), I have two rod holders on each side of the vertical hardtop stanchion that work well for the outriggers (top rod goes to the outer line). I can then run two more rods from the gunnel rod holders, plus hand lines from the rear cleats. On my buddy’s 30” Grady, he doesn’t have the stanchion rod holders, so we run the outrigger rods off the front two gunnel rod holders. It works OK, but a bit more prone to tangles when the bite is on. You could put the outer rod in the corner rocket launcher, but they can be a pain in the butt to get down with a fish on.
