Dear team, I have watched your fantastic video on making a new car bonnet in carbon fibre and this has given me the idea that I could do something similar with my very heavy centre boards on my Hobie 18 catamaran. The centre boards are about 1.2m in length and 35cm wide with a large handle and small flange at the top. The foil section is symmetrical (like an airfoil basically). The existing foils are very heavy and cumbersome to use. I am thinking that 2 moulds could be made that would basically create the new foil in 2 halves (length ways). Making the moulds and the 2 halves would be the straight forward part, it's the joining to create something stiff, strong and water tight is more tricky to visualise. Alternatively I could be barking up the wrong tree. I have attached a rough sketch of the foil and your advice would be welcome. Mike Cook

What he says lol.
If you are designing the fin from scratch then you could design a bonding flange into your mould. Using a core makes things a bit simpler in that sense as you are bonding both to the carbon and the core.
