Menghitung Ordinat YFACE dan YBACKTitik-titik koordinat yang dibutuhkan oleh profil dapat dihitung dengan formulasi yang diberikan oleh Van Gent et al (1973) dan Van Oossanen (1974) adalah sebagai berikut :

Untuk Perhitungan Propeller Nose Radius mengacu pada rumusan di Buku The Design of Marine Screw Propeller hlm.72Setelah mengetahui nilai masing - masing (cr,ar,br dan Sr) diatas, maka langkah pengerjaan dilanjutkan pada penentuan penampang ketebalan tiap bagian daun menggunakan rumusan dan tabel dibawah ini :Untuk P>0(Marine Propellers and Propulsion hal 104)YFACE= V1(tmax tl.e)YBACK= (V1+ V2) (tmax tl.e) + tl.eUntuk P
