Many kayaks and boats are made to suit the 4 hole base pattern of Scotty, RAM, Cannon, Fish-On, and many others. Now RAILBLAZA’s original accessories can easily be fitted to these vessels. After many requests we introduced the StarPort HD. This is a stylish, four screw base mount, which comes with the popular RAILBLAZA locking slide, and is lower in profile than others on the market. The StarPort HD can also be centrally mounted on many popular track systems, with the added versatility of tool-free adjustment. Just buy our TracMount Kit 03-4109-11, & open up the central hole bosses with a 6.5mm (1/4 in) drill bit.
