rigorous solution:
SIN 4 = 0.06975
1 mile = 6080 ft.
1 mile X SIN 4 = 6080 X 0.06975 = 424 FEET
therefore aim 424 FEET (per nautical mile per total distance travelled .... or add 4) to the 'right' (windward side) of your course and you will be 'ded-on' at your arrival: 145 + 4 = 149M
If the wind would be from the east and causing the same value of leeway, then subtract 4; 145 - 4 = 141M
Yes! Agreed..I subtracted at first....it is an add.. 149 deg. steer into the wind..
