There appears to be enough room to add one chair mount opposite the swim ladder side of the boat. Not sure I would add two chair mounts and here is why;
Is it possible that a floor mount located infront of the swim ladder could be a "toe stubber" ? Worthy of a good hard look.
Prior to picking up our new SLi, we had the dealer add a second table mount up in front of the right lounger/seating area.
I was specific where I had the table mount located as to not look like an after thought. I made sure it was centered and placed the same
distance as the rear floor table mount. I like the option of two tables. I have not ordered the second table & post yet.
GL and post a few pics of your new TOON!
