Letlmet,
If you're using a symmetrical spinnaker by following these guidelines you will be fine. assuming the boat is on autopilot and you're secure enough to walk forward of the mast.
1. Preset the fibreglass cone and the head on deck hoist the rest from out of the front hatch.
2. Make sure the spin halyard and the sheet are outside of the jib/genoa sheets
3. after the sleeve is pulled all the way up,
4. Preset the pole and set the afterguy. If you are using an Asymmetrical spin. ATN tacker of the headstay and snug the tack line.
5. Set the boat on a course 150 degrees apparent wind direction.
6. Go forward of the mast have a seat, pull the line that lifts the cone to the top. leave a fair amount of slack tie of to lifeline with slip clove hitch knot.
7. Go back to cockpit crack open beer turn boat to not more than 130 degrees apparent wind direction.
8. Continue consuming beverages and enjoy.
9. Reverse process to take down spin, except for regurgitation of beverages.........
My autopilot is connected to the wind instrument so I set the desired wind angle and the system will control the autopilot and change the course as needed for consistent sailing and less trimming.
*Side note all spinnaker sheets have to be 2 boat lengths long for safety concerns.
