What lookout on Cuttyhunk? My chart 13218 (not the practice one) shows a windwill bearing 068 T from the monument. Is the windmill, installed in 1976, is in the same location as the lookout 41 25.10 N 070 56.0W? If not what is the lat and long of the lookout?

If that is the case, the problem is solvable.

Agree with Jack...I don't see how you determine the deviation without a chart and a known range bearing. (my chart also shows a monument and a windmill not a lookout tower)

Edit. I just found my old copy of the practice chart 1210 Tr ( training) .
It indeed lists a lookout tower and not a windmill.

Same place as the windmill?

Mr A - what is the true bearing from the monument to the lookout tower.

 

[jackdale]

Solution

T bearing monument to lookout = 060

V = 15W (from my chart - is training chart different?)

M bearing monument to lookout = 075

D = 075 - 070 = 5 E

C = 300 (ships compass) +130 (relative bearing from pelorus) - 360 = 070

So how many of you have a pelorus on board?

I'm using chart 1210Tr...thanks davidpm, rgscpat, jackdale and tempest for helping me thru this, questions are 7 & 8 in the above link.

My chart shows only one tower

What is the true bearing between the towers?

Jack

The solution

T = 003

V = 15 W

M = 018

D = 3 W

C = 317 + 064 - 360 = 021

I had to put my reading glasses on..for this

My glasses are an aid to navigation.

Thanks for that. I will edit my post.

and I was wondering do sailors even use charts anymore other than emergencies? and would flying and sailing require a similar skill set?

I use paper charts to do my planning and plotting. I also know how to use electronic charts (I have three different ones on my Windows tablet). I also know how to use radar fix on paper charts.

I may be an exception.

Being able to paper charts is a skill that should be learned before one starts to use the electronics
