I have a 130 with foam loft and therefore generally do not bother to install the 110. As for reefing, the easiest is always doing it at the dock but it is not always necessary. When having to do it while underway, it depends on wind and sea conditions. If around 22/25 kn apparent, I set boat on a real tight closehauled course, put main into the wind with traveler down, lock the autopilot on, drop the main to reef point, then go to mast & hook it to gooseneck, & back to cockpit to retension main halyard and take in reef line, followed by proper main & jib trimming for course desired. If wind upwards of 25/30, I heave to and then proceed to the reefing. As usual, practice makes better. Good luck
