What is IALA IALA is The International Association of Marine Aids to Navigation and Lighthouse Authorities. (IALA) is a nonprofit international technical association. It was established in 1957 and it provides nautical expertise and advice. IALA encourage its members to work together to harmonized aids to navigation worldwide and to insure the movements of the vessels are safe and cost effective. IALA is known for its buoyage system In order to minimize the number of changes to the current existing systems, are you all decided to create a system divided into two regions. Which depends upon geographical location. There is region eight and there is region be. North, central and south America is…

Lake St. Clair, Michigan Lake St Clair lies between Lake Huron and Lake Erie. It is connected to Lake Huron by the St Clair River and to Lake Erie by the Detroit River. This lake/river system is one of the busiest waterways in the world. With over 5,000 ships transiting each year, it is busier than both the Panama Canal and the Suez Canal combined! Both the lake and the river were named by French explorers in 1679 after St. Clair of Assisi. Along with the Detroit River, the system is actually a strait as it joins two large bodies of water and lies between two large landmasses. facts about Lake St. Clair and its…
Regulatory Marks are designed to assist sailors navigate oceans, seas and lakes. It inform sailors of restrictions or dangers that they are approaching. Regulatory marks are white "can" buoys that have an orange shape on them. Those marks can display a warning or other instructions. Some of them to control speed or notify the sailor of dangers such as rocks.
NON-LATERAL AIDS TO NAVIGATION are used to mark fairways, mid-channels, and offshore points, and have unobstructed water on all sides. They can also be used by the vessel operator transiting offshore waters to identify the proximity of intended landfall. Lighted/unlighted buoy may show a red topmark.
Double Sheet Bend https://www.youtube.com/embed/g2Z7aKwWa6Q The double sheet bend knot shares all the features of a Sheet Bend except that it is a more secure knot. Accordingly, it is the preferred knot of the two.
Sheet Bend https://www.youtube.com/embed/aK-1LJNYTIs The sheet bend knot is used to tie two lines of equal or unequal thickness together. The sheet bend knot can be tied anywhere into another line and therefore it can be used to lengthen or shorten the overall length of a line. Always make your bend (U shaped loop) in the thicker of the two lines.
Lateral Marks These show well-established channels and indicate port (left) and starboard (right) sides of the channels. Port marks are a red can shape. At night, a red flashing light may be shown. Starboard marks are a green conical shape. At night a green flashing light maybe shown. Lateral Aids to Navigation generally indicate which side of an aid to navigation a vessel should pass when channels are entered from seaward. In the absence of a route leading from seaward, the conventional direction of buoyage generally follows a clockwise direction around landmasses
