These Railblaza ports are so awesome that we fit them as standard features onto most of our boats. They are bonded to the tubes and will hold the oars, rod holders, fish finders, bait boards etc. But we are often asked to add extra ports when our customers are ordering their True Kit boats so now we have this option. The price includes the RibPort and the time and materials needed to bond it to the tube - just tell us where you want it. Simply add as an extra to your cart when ordering your new True Kit.
