Searching for a good CAD hydrofoils setup to start with!

hello!! i’m a surfer and a maker, i build everything i need normally and i have everytool for every application.
i generally build wood surfboard and eps bord but i want to get in the foils now.

i want to build it and learn how to ride it… i get a lot of fun on building vs buying.

i found this old file… do you think is a good design? i cannot contact the designer to ask if some one have actually tried already…

does someone can reccomand a foil design in CAD that actually work in real life so i can avoid to waste money and just get something that will work for sure?
