    I'm new to boat building (I've build one laser so far) and I'm building a catamaran foiler. The design is similar to the ifly15 but slightly smaller, I've never made a foiler so dont know the dimensions to use. What variables do i need to take into acount and also just some general advice on how to build the foils and mabey a trailing wand systeme (if realisic for a homebuild). I'm hoping for this to be able to foil in around 10-20kts
    Not sure if this is the right forum but thanks in advance to anyone who helps
