Keep in mind that as you dive, you should hold your mask and snorkel gear with your palm and two fingers. Once in the water, take a major jump forward; check your gear and signal to the vessel saying all is well. In the event that the water conditions are rough, it is better to not dive while standing up. Rather, a seated jump into the water is ideal; this is perfect for shallow water as well. A stepping ladder jump is also an alternative; here, you drop the stepping ladder and put your gear on once you get on the rung that is submerged in the water and then dive in hands first.
