Oh, one more thing that I noticed in your pics is that your pallets have the cut-outs for the forklifts to use. Take a lesson learned the hard way. Position the side with the cut-outs towards the water when loading them on the boat. If not, after you add your weights and try to slide the overboard the cut-outs will hang on the edge of the boat and then it is heck to get them off with all that weight.
Hope this helps and like I said NIMROD is the guy to talk to if you run into any problems or have questions.
Let us know how it goes.
