DSS foil type of design

Hi everyone

I am looking into wasting some money on modifying my boat.
She is an 18ft Jeanneau Microsail (replica) it was built here in South Africa with a solid deck (no balsacore) and strengthened in a few areas that were issues on the original boats. A 1.5m fixed keel was used instead of the drop keel.

With a fixed keel it has opened up the cabin area a lot but this is no luxury boat, it is purely used for racing.

I would like to add something along the lines of the DSS Foils used on a 21ft Mini Transat that is photographed on their website.
The one thing that I cannot wrap my head around is the controls of the system.
What controls are used to push or pull the foils from windward to leeward?

I have thought of an electric system but that involves using large motors with high holding torque to counter the foils pushing back in and in turn will draw a high current constantly.
The second idea was a hand crank system but what would I use to hold the foils in place and what type of system will it be: belts, worm screw, etc.?

I would highly appreciate some inputs and ideas into controlling the foils.

Thanks

The boat's only 18 ft - just do it by hand. A line attached to the middle of the foil led to a block on each side of the hull and thence to a cleat on deck or in the cockpit. It's really no different than rigging a traveler.
