Best value for money build on classic board foil set up

Hello Gurus!

What is the best build in 2002?

I currently have an Axis Hps980 with 85 mast and blueplanet 4.10 board that I use for winging in Florida. There is limited wind supply here and after 2 years windfoiling I am now thinking about electric power!
Objective is to go upwind on electric and get the downwind with waves power.

What are your recommendations to build with minimal toolset at home. No welding, no 3D printer…

Thanks for your insights!
