One of the joys of sailing late at night (usually due to lack of wind during the day) is the phosphorescence. As a little kid I loved going down to the beach at night and watching the waves glow and stomping on the sand to watch stars shoot out from my feet.
On the boat it is a different view. I have stars in my wake. Some times more than others but they are still there. When I end up rowing is the best though. It looks like I am stirring some magic potion. Back and forth, glowing all around. It is a simple pleasure but it makes me smile every time it happens.
