I've been sailing my DS I single hand, off and on, for over 20 years with no special rigging. The trick is pick your days, you know, days with just the right wind. Sit on the rail , at about in the middle of the centerboard trunk, with the main sheet over one knee and the jib over the other knee, so you know right where your sail controls are then you need them. I sail in Colorado, along the front range, and the wind speed
and direction can change very, very quickly, so I'm ready to make an adjustment very, very quickly.
You could also have a sail maker put in Jiffy Reefing points on your main sail to shorten sail when you need to. Our Day Sailers don't sail very well with just one sail, so it's best to shorten the main, before it gets too bad and we want take down the jib.
How ever, our Day Sailers do "heave to" very well.
Back the jib.
Let main all the way out.
Point the end of the tiller all the way over
boom.
Your Day Sailer will stop foward motion and drift sideways very slowly.
