How does that work then?modern racing yachts are using Dyneema more and more, instead of stainless bottle screws.

Usual caveats - I'm no expert; but 
Comments; kevlar ropes are prone to damage if bent at too tight a radius, not sure how dyneema performs in this respect. Anyway, I would be inclined to use traditional deadeye techniques if using small dia cord to replace bottle screws.
It will at least be easy to see potential problems and replace/ reinforce as necessary at an early stage.
It works well using basic cord on dinghies, and Debbie is only an overweight dinghy with a lid on.
But dinghies are normally only used for day sailing from a beach (unless your name is Frank or Margaret Dye)

Still can't figure how you're going to achieve and maintain the required tension and precision of adjustment (although I'm sure it would be strong enough) at less cost than bottle screws. How cheap do you need them to be? Gael Force SS fork/fork bottle screws.
High tech string v. ss bottle screws

My pal with the fast trimiran uses what are effectively light plastic versions of old fashioned dead eyes, but laced with thin, v. strong, high tech string. The overall weight is apparently less than ss rigging screws, but I suspect that for more normally constructed boats the advantage is likely to be insignificant.
