Our Lagoon 440
has a Profurl system, we have a Harken
53 electric on the halyard
which then is used on the downhaul/drum.
Absolutely a pleasure to use, fast easy and safe. Reefing anywhere between 1 and 100% in a minute.
Keeping a little tension as you downhaul ensures a tight wrap. No different to a headsail furler
in that way.
Beauty of it all is if you get jammed you can still drop the main.
Full battens give great shape we are totally stoked!
