Chine Design

I am currently researching the design of chines or "Lifting Rails" on a deep V hull. Hoping to get some recommendations on written material providing details. Any help would be greatly appreciated.

I remember a few years back when Volvo was selling speedrails -- I'm not sure how much improvement you would see on a typical hull though, or if there were any handling "side effects". I see Ocke Mannerfelt's Batboats are doing really well now, but I no longer see speedrails for general sale...

So far I've gotten one well meaning reply from a directed source indicating a couple of books that "might have information" and it turnedout there really wasn't much. But at least this was a reply. COuld it be that the subject of Chines and Lifting Strakes is beyond the entire community of Designers. Or possibly a topic considered VooDoo? Or maybe them that has it is gonna keep it? Well I hope this provokes some commentary. Cause I'm still looking.

Prediction of lift/drag values, dynamic stability, etc. in the interface between hull, air, and water surface via mathematical formulae quickly becomes VERY esoteric and is best practiced by post-graduate physicists and hydrodynamicists - check out papers on the topic at The Society of Naval Architects & Marine Engineers (SNAME). The usual practice among lesser mortals is to use general formulae from texts such as Lord's "Naval Architecture of Planing Hulls" and others to get a baseline data set, then refine the design with public and proprietary hull data from previous designs or towing tank experiments. Usually the designer has a "good idea" and then builds either a full-size or scale model and performs calibrated trials to prove and improve the initial design. Mostly seat of the pants (in an expensive and formal way) engineering, I'm afraid.
