Sea Ark boats without the 22 degree accessory rail generally use the pedestal style mounitng for the baseplate.  Pedestals are most commonly used when the gunnel is less than 7-8 inches (approx.) from the boats casting deck.

Plan sufficient span of the baseplate to get the cup over the edge of the rub rail outside the boat.

  • 12 inch baseplates:  4.75 inch span across gunnel.  Typical for most Excel boats (ie Tournament Series)

Pedestal Riser for BaseplateBaseplate Dimensions

Baseplates sit atop the upper pedestal plate using one of two mounting methods.

  1. Thumbscrews:  a couple of nylon thumbscrews that act as a quick removal as well as a strain relief should the downrod hit something while deployed.
  2. Magnetic Switches:  dual 150lb holding strength magnetic switches hold the baseplate to the pedestal

All Standard baseplate systems include a plastic coated stainless steel tether to hold the baseplate to the boat.  Should the downrod hit something in the water and cause the baseplate to break away from the mounting, the baseplate will follow the downrod overboard and into the lake.  If you do not wish to dive for your baseplate, the cable is the best means to hold the baseplate to the boat.

Assembly Options​

Pedestal Height 1 Pedestal Height

This is the total height of the pedestal needed. Simply measure from the deck to the top edge of the gunnel and add 1/4 inch to clear the top edge of the boat.
Please plan for this exact measurement only. When we build your pedestal, we will ensure that once assembled it will match the height given.

Example: If you need 4 1/4 height, select the 4-5 inch pedestal and use the next drop down to select an additional 1/4 inch.

Movable / Removable Pedestal Mounting 2 Movable / Removable Pedestal Mounting

We offer a mounting plate for a pedestal that allows the user to remove the pedestal and baseplate from the boat or to move the pedestal and baseplate assembly from one side of the boat to the other. This system comprises the lower pedestal components shown in the photo.

2 pcs of mounting plates
1 pcs lower pedestal plate to fit the mounting plates.

Leave blank to have the pedestal mounted to the deck.

Baseplate Material and Length 3 Baseplate Material and Length

Baseplates (the part that holds the downrod) can be made in a polymer material or in Aluminum and are held with either Thumbscrews or magnetic attachment.

Polymer baseplates are considered light duty. The water fished is relatively clear and the user is unlikely to run into underwater obstacles. Trolling speeds are limited to about 4mph maximum using the base Marine board and Aluminum baseplates.

Magnetic baseplates release at a slightly lower speed of 3.5mph and also release more reliably than thumbscrews. As such, they are a good choice for any type of fishing

Aluminum baseplates are considered heavy duty. The Water fished may be full of stumps, trolling speeds can be high. River fishing is likely.

Refer to the outline drawing below to determine a proper baseplate length.
