Chinook Power Plate

The Chinook PowerPlate makes it simple to bolt any windsurf board with a Powerbox, Tuttle or Deep Tuttle fin box to the common 4-hole plate pattern found on most kite and windsurf foils today. An easy way to turn an existing windsurf board into a windfoil board.

• Use the included bolts to screw the PowerPlate to the 4-hole plate on your foil.
• Mount it to your windsurf board through the fin box using your current fin bolt(s).
• Fore & aft fine tuning with the multiple mounting-hole system: forward = quicker lift, backward = slower lift.
• Made from 2 pieces of solid aluminum, with an attached 3/16" foam pad to protect your board bottom.
• Fits Naish foils hole alignment plus others (see the hole-spacing image to check compatibility).

Head options: Deep Tuttle, Tuttle or Powerbox — pick the one that matches your board's fin box.

User instructions:

1. Be sure to use a metric 6 mm fin bolt.
2. Be careful not to cross-thread the fin bolt.
3. Get at least 12 complete turns into the PowerPlate (max. 16 turns, or 3/4"). You may need a longer screw.
4. Tighten the fin bolt hard enough to compress the foam. Check and re-tighten as needed.
5. If your board has a big V-bottom, add extra foam to the outer plate edges for lateral stiffness.
6. Always use a leash regardless of your foil/fin box setup — an impact with a log or other object could cause your foil to sink.
7. Adjust the head or plate mounting bolts to your preferred fore/aft position.

Wing forward = more lift. Wing rearward = less lift (better for learning).
