Foil Mould

The hydrofoils are manufactured in female moulds. This is for a couple of reasons:

  • Producing multiple sets is less work - ie front and rear foils
  • The foil section is more controlable

The moulds were constructd by routing out a rough foil section from a setion of plywood, then using a template to apply filler to form a good surface.

I assembled the mould in a n shape so the top of the hydrofoil and half the vertical foil is moulded in one piece and the mould for the vertical mould is shared between each half. While this means multiple foils cann't be molded at the same time less time is spent making the moulds. The photos below shows a close up of the mould with half a foil section in it and the complete mould with a vacuum bag round it.
