Step by Step Explanation

1. Measure the distance from the silo to the southern most tip of the penunsila. As a hint, if your finger is on the southern most tip and your finger forms a range with the radio towers on the Newport coast, then the tip is on that range as well. You can plot that LOP between the towers and the tip of the penuninsila. Measure the distance with your dividers between the silo and the tip of the penunsila (in range with the towers) and you get .2 nm.
2. Multiply that distance by ten. (.2 nm x 10 = 2 nm)
3.  Determining your position you should come up with 41º 27.8’N 71º 12.3’W or within .2 nm.
4.  Calculate this by multiplying the distance on the chart from the silo to the G “1” BELL buoy (1.2nm) and the distance between you hand and eye (6.66 inches) and then dividing the product by the width of your hand (4 inches). ( [1.2 nm x 6.66 in = 7.992] / 4 in = 1.998 nm rounded to 2 nm) NOTE: The inches are irrelevent in this equasion, you’re looking for ratios in nautical (or statute depending on where you are) miles.
5.  Yes – they are both 2 nm.
6.  Yes, if you continue at 282º PSC (270ºT) you’ll pass between the rocks and the tip of the penninsulia at about .2nm (.1 nm if you’re working off the cross rather than the green squigley) north (Whew! That was close!).
