To find north using Cassiopeia, look high in the northern sky to locate the five bright stars that form a distinct "W" or "M" shape. Focus on the central peak of this shape, which acts like an arrow pointing out toward the open side of the constellation. Draw an imaginary line straight out from this central bend and extend it about five times the overall width of the constellation. This line will lead your eyes directly to Polaris, also known as the North Star. Since Polaris sits directly above the Earth's North Pole, facing this star means you are looking exactly due north. #stars #sailing #sailor #sailboat #space

Protect yourself and your wallet before setting sail on your next charter. Document the exact condition of your charter yacht - especially existing wear and tear like scratches on the outboard engine. #sailing #bareboat #sailingvacation

Why can’t you drink Seawater? Seawater contains about 35 grams of salt per liter. Your body fluids contain salt too — but seawater is roughly four times saltier. And the water in seawater is usable. The problem is what comes with it. When you drink seawater, your body absorbs both the water and an enormous load of salt. That salt raises the sodium concentration in your blood. Through osmosis, water moves out of your cells and into the saltier fluid around them. The cells begin to shrink and stop functioning normally — and brain cells are particularly sensitive to this. At the same time, your kidneys try to remove the excess salt. But your kidneys can’t make urine as salty as seawater. So to flush out all that salt, they have to use more water. That means eliminating the salt can cost your body more water than the seawater gave you. Now you’re thirstier than before — but every additional drink of seawater adds another load of salt. The cycle accelerates. Eventually, severe hypernatremia and dehydration can cause confusion, seizures, organ failure, and death. So seawater contains plenty of water. Your body just can’t afford the salt that comes with it. #sailing #sea #ocean #boat #boating
