Yeah, it puts a lot of pressure on it but we used the electric winch to reef the headsail. I specifically put a ProFurl on because of the steel bearings and you could reef it under load.

At 3 in the morning when I was asleep the wife could reef the headsail by just loosening the sheet a bit and hitting the button on the helm to wind the sail up. If it needed more reefing she would just let a bit more out to ease the sail and then use the electric to roll it up more. She liked the ability to reef the headsail using the electric winch and not having the sail flog all over the place. A lot of pressure but the ProFurl never complained.
