Talk About It
Electronic navigation equipment has become quite common in modern yachts. It provides high accuracy and facilitates the work of the captain in the sea.
The more complex the system, the greater the likelihood that failures in its work will be missed is. But many factors have significant destabilizing impact on the work of electronic navigation equipment: fluctuations in supply voltage, humidity, thunderstorms, aurora magnetic storms, failures in the reception of signals due to damage to the antenna. Repair of electronic “black boxes” is not possible without a specialist. It was then checked training, foresight and ingenuity of navigator.
United States Coast Guard research of the causes of accidents of small size fleet showed that the main cause of accidents is the absence of captains of sufficient skills and knowledge on the fundamentals of navigation.
What to do if all the “magic electronic boxes” after a fierce storm faded and there is no certainty that the deviation of a single operating magnetic compass had not changed?
The basic rule – do not get rattled. First of all, according to the visual features it is necessary to analyze a risk of the shallow depths and take all necessary steps to move away from them. What are these symptoms?
The changing nature of sea wave while maintaining the overall direction and strength of wind. You should always bear in mind that with decreasing depth any waving becomes more abrupt and disorderly in appearance, as the wavelength decreases, and its speed increases. The same phenomenon of “crowding” can also be seen in the shallow waters near the windward shore, where arriving by sea waving “breaks” due to the sharp decrease in the depth and mixed with the reflected waving from the shore.
Increasing waving near the coast is a sign that from the windward side of the vessel there is a significant gap of the coastline, reinforcing effect of the wind. This local amplification excitement can be seen passing along the ridges of the islands to leeward, when in a beam of the ship there is the strait separating the island. The same phenomenon can be observed coming out from under cover for the coast or passing broad and deep bays, jutting far into the shore.
Changing the direction of agitation can occur when a ship passes by narrow, bounded by high banks, the general direction of which does not coincide with the general direction of the wind and waves.
Changing the direction and force of wind, while maintaining the general synoptic conditions. With the approach of the vessel to the high banks or individual islands it can often be seen weakening of wind power. If this is accompanied by a decrease in strength of waving, it serves as a reliable warning of close proximity to the coast.
Local changes in wind direction, accompanied by its gain, may occur during the passage of a vessel in the vicinity of deep ravines and gorges, bays at the entrance of narrows, near the low Isthmus of high rocky headlands, etc.
Change of the color and transparency of water. When approaching the shore with a muddy bottom, near the mouths of major rivers, out flowing into the sea a considerable amount of fresh water, which differs from the sea of color and transparency, when approaching the high rocky shores, the depth at which is sharply reduced, the experienced eye of the skipper will be able to discern the difference the color of water – dark in deep and more bright and transparent in the little ones.
Having satisfied yourself that you are in safe depths, proceed to determine location and direction of motion – astronomical methods will help you with this. Good luck!

So, you have become a happy owner of the yacht – motor or sailing, new or used – one thing is certain: in your eyes it is the best and most beautiful boat in the world. And probably you have already decided where your beauty will live – is likely to agree on parking at the local yacht club. However, more and more ship owners, faced with severe weather conditions, turn their views to the south – to the azure waters of the Mediterranean Sea. In this article I will try to help those who are determined with their choice – where and how to keep your boat.
Own yacht in the Mediterranean. Utopia, you say? Is it a complicated and expensive business? From my point of view, such a decision, despite the obvious at first glance complexities has many advantages. The first and the most important: safe navigation season on the Mediterranean lasts almost 9 months, from April to November. You can walk in the winter, but the weather deteriorates dramatically in January – through 30 th latitude cyclones begin to go, bringing with it a violent storm, and long passages at this time can be risky. Dry up rivers in summer begin to bear at sea turbulent water flows, temperatures drops considerably. So, up to October cruise activity in the Mediterranean softens gradually, almost sinking to 15 November. Sailing world begins to wake up from sleep somewhere in March, and to the end of April almost all areas of the Mediterranean Sea are ready to take the cruiser once again.
Dozens of books are written about the cultural and historical richness of the Mediterranean, and be sure – you will find here a place to your taste: a secluded anchorage on the north coast of Majorca, eastern markets in Morocco and Tunisia, or the luxury of Nice and the Cote d’Azur. Many sailors spend year after year, exploring the coast of the country by country: Spain, Italy, Tunisia, Turkey, and Greece. Yacht permanently located in the Mediterranean, provides a unique opportunity to spend the holidays away from beaches where there are a lot of people, hotels and tourist restaurants – when you want it.
Moreover, when the separation costs of the yacht for a few participants, it can be very cost-effective solution of the issue of summer vacation – because the yacht is both a hotel and a means of transportation.
The final point – this is freedom of movement between countries. If you take care of Schengen visa in advance, then will no problems when crossing borders of other countries (visas to Turkey, Tunisia and Morocco are placed in the port of arrival). So I tell you advantages of cruise on own boat, but you have to decide whether it is suitable for you.

People who live by the water, certainly are dreaming of a boat or yacht.
