1. The first thing that you should before you sail is to check the weather. You should check with your local weather center in order for you to determine whether the weather will be perfect for sailing or not.

2. You need to check that all the equipment and materials that you will need are already prepared. You have to make sure that the materials are also in great condition before you sail.

3. As much as possible, you should stay away from locations or destinations that are restricted to both professional and beginning sailors alike.

4. If you are going to sail alone, it is best if you inform a friend or a loved one where you will be heading to. In that way, if something bad happens, they know where they can find you.

5. Before you leave, you need to drink plenty of water to prevent hydration. It is still better to be safe than have problems or be sorry in the end.

In most cases, reflected sunlight determines the color of the sea. Tropical islands have turquoise seas because the water absorbs blue and reflects the red in the sunlight. If you go diving, you will notice that the water become bluer the deeper you go. This is because only the blue light waves are able to penetrate deep waters. Sometimes when there is a storm at sea, the water can look even black. The dark storm skies leave no light for the water to reflect.

Other times, algae growths are responsible for the various different water colors. In the Red Sea, there is an algae bloom that creates red of the water. Algae also creates the green hue of the Colorado River in the Marble Canyon during the spring. Other parts of the Colorado River have a red tone due to sediment in the water.

These are just a few of the different reasons why the sea has different colors in different place. Depending on location and conditions, the sea can take on a multitude of surprising colors.
