Ideally suited for gunwales of smaller tinnies, vertical cockpit wells on kayaks and any other application where you have a vertical surface, but need a horizontal StarPort. Fitted in only minutes, and sold with all necessary stainless steel fasteners the SidePort is a fantastic mount and great value for money. IMPORTANT: Use of petroleum based lubricants on the StarPort slide will cause failure. Silicone based products are best suited .
