The Hobie 16 doesn't have an adjustable downhaul. When I am solo and out on the wire, I leave the jib tight and handle the tiller and main sheet. To come about, I slack off about a foot on the main sheet, cleat it and throw the sheet onto the tramp. I immediately start to come up into the wind and when enough force is off the sail I slide in, get unhooked, pass the tiller around to the other side, move over myself and hook up again. I then lay my foot or leg on the tiller to keep turning and wait for the backwinded jib to carry me around. When the main snaps over, I release and recleat the jib and get back out on the wire. It takes longer to describe than to actually do it. Tacking isn't much slower since you wait for the jib to carry you around anyway.
