SPP™... koristi regresijske analize za izračun sila na trupu bez postojećih North VPP podataka

SPP (Sail Perfomance Prediction) koristi se za predviđanje relativnih performansa jedara između različitih dizajna jedara ili brzine trima. Koristeći SPP dizajneri mogu trenutno usporediti performanse novog dizajna jedra sa osnovnim kalupom. To omogućuje dizajnerima da testiraju do 10 puta više oblika u odnosu na individualne dizajne zahvaljujući velikoj matrici u Flow-u koja spaja ove rezultate u North VPP-u.

Osim toga, SPP se može koristiti kada dizajneri nemaju dovoljno podataka za North VPP.
