The afterguy will be close enough for now. That's it for the hoist, set the auto pilot where you want it, and fix up the pole height and sheet trim. Sailing much below 150 AWA by autopilot is a bit dicey, and the boat is happier on a bit of a reach no matter what the sail combination is. See how the spinnaker is exposed as the pole is lifted and squared aft. With the spinnaker pole properly trimmed, notice how much of the sail is to weather of the centerline.
Nets are old- fashioned but work just fine, and eliminate the worry of a wrap.
Cheap and simple, and works like a charm. The extra sail area is great as long as the boat keeps sailing downwind, and it is important to douse the spinnaker well before boat control becomes an issue. This releases the tack, and the sail will flop around behind the main until the sock line is pulled down. Pulling in the lazy guy or the sheet will help keep the sail behind the main until it is socked. In lighter winds, simply easing the pole near the headstay and sailing low is enough to collapse the spinnaker behind the main, and simply pull the sock down when the sail collapses.
