There are few solid rules to be put in place to avoid yourself to be lost:

• Compass, Log ant clock must be always efficient.
• Write; always write when you leave the harbor the hour, the direction and the speed you have.
• Update each hour the above data's.
• If you have an electronic log use the average function for your calculation.
• If you have a chronometer switch on it when you start. It will be useful if you are lost to track a circumference from your starting harbor to know the area where you can be.
• If you enter in a storm try to fix in mind the average data (time, direction and speed). This average data's will be better than nothing when you have to write down on a map your path.
• If you are lost in the night use your sense before ask for an external help. Look for coast lights; big cities can be saw from more than 100 miles. If you start from Ligury you should be able to identify Genoa and Nice cities lights into the Corsica channel!
• ...and, if really you think to be lost you still have the opportunity to learn how to know your position by the sextant. Please click on my CNA1 (Corso di Navigazione Astronomica 1) and enjoy.
• Last but not least.... if really you are going to leave the spirit you can use a GPS!!! ... but don't forget to have a set of new batteries onboard.
