I'm a fan
For many years, sailing beaten-up club boats, I couldn't figure out what the curious plastic cringles in the sail, and strange zippered flappy things were. Then after attending a boatshow, I realized they were dutchman reefing systems, with the guide wires removed.I've met no shortage of sailors who frown apon this system (mainly because the guide wires can make the sails grubby) but they tame the main, without the chafe associated with lazyjacks.Mine were standard on my Hunter (as were many). I was unimpressed until I spent sometime with someone (who, based on a reference to the name of his boat, I thinks was the dutchman himself, Martinus Van Breems) at a boatshow. He took the time to explain how to adjust the system (which took 10 mins) and oh happy day! I can now dump my 500sq ft main single handed!If you single/short hand, you could do far worse. And based on my encounter with Martinus, you can be assured of superb customer support. So much so, I promptly ordered a Dutchman boom brake.
