Given the lines of this boat, I'm not surprised :-) Boatman and SailsToo laid it out, tho.
Before you lay the helm
down, bear off a tad to get to maximum speed, then, on the call, lay the helm down about 2/3 of total travel or something like 30º. In this boat you'll likely have to hold the helm down by sticking the tiller twixt your legs while you work
. Watch your headsl luff. The moment you see a ripple, start the headsl sheet completely. Leave it started till the headsl is on the new side. Now make sure by watching your telltales on your shrouds that the wind is 15º or 20º on the new side. Then SLOWLY haul the new lee sheet, paced to the rate of turn, so that you come to the mark on the sheet when the wind is 60º or so on the new side. Then, but only then, can you bring her up on the new course till you see a ripple in the headsl luff. Then you fall off a tad to keep the drive in the sail.
An embellishment on the "standard" procedure is to leave the headsl sheeted on the "old side" till it backwinds as the boat is turning. That will help to drive the head
through the eye of the wind and fall you off on the new side. Again, you watch your telltales on your shrouds, and when you have the wind 20º on the new side your start the headsl sheet on the old side and haul taut on the new side.
That will work
in this boat when you have a bit of wind. In a zephyr it might not work due to the lines of the boat. But as others have said, if you miss stays, just wear her. "Wearing" is the act of bringing the wind on the other side of the boat by turning the stern through the wind. "Gybing" is act of bringing the boom oven
onto the new side in a controlled fashion, and in an intrinsic part of wearing. Gybing in any amount of wind can be hard on the gear
and even dangerous unless you know how to control the motion of the boom by using the mainsheet. When you wear, the headsl will take care of itself.
Pick yourself a day with 10 or 12 knots of wind and just go out and practice, practice, practice! In such gentle, but sufficient, wind in a tiller steered boat this size you should be able to do it all yourself in one well coordinated "cockpit dance" without using winches or any other kind of "help".
