    Thomas K.  Your 8th Sep 2243. Am away from home, so no crib available.  I'll try sailor's way for a change, not that I are much of one.  You shoot 25.55 (Hs) + 50 P in A, -2 refraction equals 26.43 (Ho).  Using Intercept Method, for assumed position 53N 000.33W, HC is 26.40 Az is 081. Therefore, plot position line 26.43 - 26.40 equals 3 towards along 081True. I just wish these touch keys were larger, or my fingers narrower. DaveP
