Maximum Loads of Inflatable Accessories?

Is there any info available on the maximum allowable loads for the 79052000 i – ACCESSORY HOLDER KIT, the 79052006 i – HARDWARE ACCESSORY KIT, and the 79052016 i – TRI RING KIT?

Assuming they are all correctly installed, I'm guessing the tri rings are strongest followed by the hardware mount, followed by the accessory holders?

Part of the reason I ask is that I mount my rod holders on a 1/2" poly board strapped to the forward sail tri eye, the handle, and the seat tri eye. I use the accessory holders as "feet" for stabilizing the board rather than gluing them permanently to the boat. This gives me much more flexibility & leaves the boat "clean" if we're not using it for fishing.

I want to add another cleat of some type about 12" forward of the sail tri eye so I can move the board further to the bow.

I'm curious how the various attachments will stand up to the stress of trolling rods & also for mounting an anchor trolley on the side.

Any load data or anecdotal info is very much appreciated!
