I have a HOOD Stoboom that is unavailable new now, but mine was hardly used.
I like in-boom systems since you can use a fully battened sail and trim it like a "normal" set-up. I ordered the Profurl but had some bizare trouble the West Australian distributer, so I walked.
I had some problems with the line-drive and the boom aligment, all now under control.
I have added some sail-reinforcements/ 3rd reef loops if things get really bad sown here close to the "Roaring 40''s" .
I just love it when I, Furl the head-sail, press the Autopilot button and walk up on deck and roll the 350'' main in about 20-40 seconds. Hard work, but easy now when I put the main-halyard on the Anderson REVERSED and a elastic cord as "brake". It gives the right tension and I can just crank like crazy. Summary: This stuff is like most gear on a boat only as god as the installation and the "set-up". Good sailing!
