There is an annual yacht race, CYC, from San Diego to Mission Bay. The fleet rafts up in Mariner's Basin overnight. A couple of late arrivals, cruising class, tied up on one end assuming there was plenty of water under their keel. Late that night masts and rigging tangled as the tide went out. Do not assume there is enough depth for your boat when rafting up.

On questions 4 and 6 on the quiz questions, the answers uses a triangle to show the GPS fix position on the chart. I thought the triangle was used for an estimated position (Dead Reconing + set + drift). Shouldn't the circle be used for a fix via GPS?

I have always used UTM coordinates to navigate on land - and the was having a hell of a time remembering which was which with latitude and longitude. The wife said it's the way you're mouth goes. When you say latitude your mouth stretches out flat, when you say longitude your mouth orients up and down. Anyway, if you exaggerate how you say it you will remember, and look stupid. A win-win.

I do not understand this question. Firstly what is a FALL? it isn't in the terms needed to know on the previous page.
The question says that at 11.55 the high water is 4m but the table shows 3.4m at 9.25 and proceeds to drop to 1.1m at 15.13.
Using the information in the previous pages on how to calculate these problems i'm not understanding why the tide would go up in 2.5 hrs and using that information i would deduct 4m-1.1 to get my height of tide.
Sorry but i'm lost.
Also i am i supposed to use the PDF Tidal curve at the beginning of this test for all questions or am i supposed to use the ones in the almanac book?

Your question on LW differences uses the MHWS of +0.2 to add to the low water of 0.5. Your answer was 0.7 but i thought i was supposed to use the reference of +0.5 under the MLWN to give an answer of 1m.
Agai, am i not understanding something.

Does HDG MAG in the table = (1) compass heading of the ship or does it mean (2) the magnetic heading (with deviation removed)? It would seem to me problematic if it were (2) because the ships compass doesn't given you the magnetic heading and you have no way of directly measuring the magnetic heading to determine the deviation.
Futhermore, in the example, why does one compensate for deviation on a HAND HELD (caps for emphasis) compass reading since in the previous section on deviation it was stated that hand held compasses are less affected than the ship's compass?

If you have a "cocked hat" fix... when computing/drawing new tracks, determining new courses, do you approximate the center of the cocked hat as the starting point for the new tracks and courses?
