You can always bring a towel, but you won't get wet. You can use it for sunbathing, and if necessary, for protection of your skin.
The fact is, that the sun runs overtime, when you are on the water. so beware of getting a tan too quick.
So: yes, bring a towel, you might need it for the purposes mentioned in this message.
