Seat Posts and Seat Bases

If you don't have an existing seat post or an existing seat base to mount your seat base style planer board caddy unit on, you can buy them both direct from us. NOTE: You need a seat base AND a post. We offer both of the most common seat post brands in the popular 2 3/8'' models. Most aluminum boats come equipped with a 2 3/8'' style seat post system throughout the boat. Some manufactures use Springfield, some use Atwood Swivel-Eze. You will need to review the pictures and notes below to confirm the style you need. The seat base that we offer works with either brand of seat post. It will only work with 2 3/8'' systems. It will not work with other size seat post systems. ** If you need a seat post AND a seat base, you will have to add them both to the cart separately.  **
