Ok I'm confused about requirements for seat bases and post for Helm and passengers in a side console boat can anyone clarify them for me? From what I understand I need a base and post and seat base that have a ABYC code of AO for the helm but the passenger need only have a AN code? Are require by the Canadian authorities? Can someone suggest a good combo of seat posts , bases and seat mounts for helm, passenger and front casting deck seat, and where to get them in Ontario GTA area.
