Any clues how to use a compass for course, wind shifts etc., maybe web sites.
Thanks

Compass for racing boats (day cruisers) : vertical flushmount
Designed for sailing boats of 8 to 12 metres (26 to 40 ft).
The tactical version of the Contest 101 compass fills two different and complementary functions :
Main steering compass on the horizontal part of the card.
Reading of the course from the lubber lines mounted in the lower part of the bowl.
Tactical compass on the vertical part of the card.
Direct reading. One only needs to memorise one figure for the three legs of an olympic course.
Double reading : from cockpit and from cabin.
Double graduation : vertical and horizontal.
Apparent diameter of tactical card : 100 mm.
Lighting is built-in the upper part of the bezel for a better light distribution on the card.
Front access to light and compensation cell.
Functional heelmeter.
Supplied with protective cover.

When the wind is oscillating in direction, as it often does, and you are racing, you need to sail close hauled, in the half an hour or so before the start, in the area between the start and the windward mark, noting the course you sail on port and on starbord tacks. As you do this and the wind direction goes through its cycle of directions (over several minutes), you will find that your heading changes on each tack. One tack will be more directly towards the windward mark (lifted) and the other further away (headed) from the direction of the windward mark. You should try to memorise the extremes of heading on each tack and of course, recognise which headings are lifted and which are headed.
Then during the race, always aim to tack onto the lifted tack. When you are getting close to the layline however, bear in mind that you may overstand if you continue too far on the lifted tack before getting another windshift.
In the enclosed waters of Carrick Roads, or out in Falmouth bay, most sailors use landmarks instead of a compass to see where the tacks are heading and to judge when they are being headed and need to tack. In open water, when there may be no landmarks ahead, the compass is used instead.
You can also use the compass to find the favoured end of the starting line.
