Nothing easier than waterstarting a 5.0 when its windy enough to use one. Wind flips the sail into position, sail clears itself once you lift the light sail a few inches high, if gusty you can usually feel when there is enough wind to try. Starts to get harder at about 6.5. Heavier sails need to be lifted some degrees from horizontal before there is enough sail area facing the wind to hold it up, and you sometimes have to wait for gust, get the whole waterstart in during the gust. Past my 30th year of windsurfing I was still learning some new maneuvers to get up in the lightest winds.
True!
And in light wind, especially with larger sails (7.0 and above), you sometimes need to clear the clue from the water BEFORE you want to sheet in the sail to waterstart. If you sheet-in and still have the clue stuck in the water, your sail will sink deep! Been there! Very frustrating!

To prevent that from happening, I usually, I swim to the top of the sail, lift it to the wind and travel my way to the boom fairly slowly so the wind has time to clear the clue from the water. This is especially true with Cam sails when the cams are on the wrong side full of water. Clue must be cleared before you can yank the cam on the other side with an energetic downward pull of the boom while still swimming! After a few of those you'll find that your head can stay above the water without using your arms!

Something useful to learn is waterstart clue first: For example, it's useful when you screwed up a jibe, you're in the water and still have the boom in hand, the sail is in the air, but you and the board already switched sides. Saves energy from not having to flounder in the water unnecessarily!
