A hydro foil base, in the context of water sports such as surfing, kiteboarding, or wakeboarding, refers to the attachment point between the hydrofoil and the board. It is a critical component that allows the hydrofoil to be securely mounted to the board while still providing the necessary stability and maneuverability.
The hydrofoil base typically consists of a plate or a mount that is attached to the bottom surface of the board. This plate has holes or slots to accommodate the bolts or screws that secure the hydrofoil mast in place. The design of the base is essential for distributing the forces and loads generated during hydrofoil operation and ensuring a strong connection between the hydrofoil and the board.
Hydro foil bases come in various shapes and mounting systems, depending on the specific water sport and the brand of the hydrofoil equipment. Some bases have a standardized hole pattern, making them compatible with various hydrofoil brands, while others may be proprietary and designed specifically for use with a particular brand of hydrofoil.
As technology and equipment continue to evolve, hydrofoil base designs may also advance to improve performance, ease of use, and compatibility with different board types. If you are considering using a hydrofoil or have specific questions about a hydrofoil base, it is best to consult with manufacturers or experienced water sports enthusiasts for the most up-to-date information and recommendations.

Custom Hydrofoil Top Plate Manufacturing
The top plate transfers load between the foil board mounting tracks and the mast. Accurate machining, flat contact surfaces, compatible hole spacing and controlled finishing are therefore important to system fit.
Unity Sports manufactures existing and custom hydrofoil top plates for brands, wholesalers and distributors. Customization can cover mast interface, mounting pattern, dimensions, tolerances, anodized finish, color, logo and packaging.
Match the Top Plate to the Mast and Board
Type 115 and Type 135 are interface options for corresponding mast systems. Before selecting one, confirm the mast connection and the board-track mounting arrangement. Send the hole spacing, slot or track dimensions, fastener requirements and mating drawings or 3D files. Matching a type label alone does not confirm fit across different foil systems.
For a private-mold or customer-specific plate, we can review dimensions, mounting pattern, tolerances and anodized finish against an approved sample. The final drawing should identify the connection surfaces and acceptance checks before production.
Quality Verification and Lead Time
Depending on the agreed design, verification can include dimensional inspection, assembly-fit checks, hardness testing, structural or suspended-load testing, fatigue testing and salt-spray testing.
Public-mold products can start from MOQ 1. Fully custom projects do not have a standard minimum quantity when the customer approves the required tooling cost. Typical sample lead time is 7–21 days and mass-production lead time is 30–60 days.
Request a Top Plate Review
Send the mast interface, board-track mounting dimensions, drawings or 3D files, expected volume, finish and branding requirements for a manufacturing review.
Frequently Asked Questions
What is the difference between Type 115 and Type 135 top plates?
They are interface options for corresponding mast systems. Confirm the mast connection and board-track dimensions before choosing a type.
Can you machine a top plate to our mounting pattern?
Yes. We can review customer drawings or 3D files for mast interface, hole spacing, dimensions, tolerances, anodized finish and branding.
What material is used for the U-AT01 top plate?
The standard U-AT01 is CNC-machined from AL6061-T6 aluminum and anodized for surface protection.
Which checks are available for a custom top plate?
Depending on the agreed design, verification can include dimensional and assembly-fit inspection, hardness testing, structural or load testing, fatigue testing and salt-spray testing.
How do we choose between Type 115 and Type 135?
These are interface options for corresponding mast systems. Confirm the mast connection and board-track mounting dimensions before selecting a type.
What information is needed for a custom top plate review?
Send the mast and board-track drawings or 3D files, hole spacing, fastener requirements, expected quantity, finish and branding requirements for a fit and manufacturing review.
