You stick a handle on the bit sticking out by the gooseneck and crank... this rotates the boom and winds the sail round it as you lower the required amount...
Mainsails set very poorly with this system... baggy bellies... go slab reef

I had one on a former sailboat of mine. It was a pre-cursor of the 'in-mast' furling so popular now. It has the advantage of being quick and highly variable in the amount of sail being set. I think the reason it never caught on is just as boatman says: never really set the main right. Having said that, I used it a bit and it worked after a fashion. However, I wouldn't want to rely on it and I think the short answer is: it's junk .

Having a roller furling boom on my 1967 Pilot Boat has been great. I had to make new sails anyway, and being aware of the lack of proper sail shape with the furling/reefing boom, I had the sail maker build the sail a little flatter. Never once had a problem. Great idea with the correct sail. Sailor Simon

They caught on and were the typical reefing system in the '40s into he '60s. Never did figure out why, though. The reefed sail with one of these systems is a nightmare. There is always a big bag in the middle and the leech is bar tight. I had the system on my first boat and ruined the main the first time I reefed. Trying to get any useful drive instead of healing moment from the main stretched the leach. It was not easy to roll in a reef and definitely not fast. You physically had to haul the leech/foot aft as you rolled the sail in to cut down on the center bag so it took at least two people to set an at all decent reefed sail. Some people resorted to throwing life jackets and any other junk they had into the middle of the sail as it was rolled to try and keep the bag out of the sail.

Slab reefing, a throwback to an older system, is just so much easier to set and easier on the sails. Roller reefing was an invention that really had no reason to happen.

I read on how practicle a roller furleur is when comming in or out the marina...can a roller main sail be used in the same manner?

at present my boat is enginless and I hope to keep it this way.

I had one on my pearson vanguard. It worked, sort of, but it's not the same thing as a roller furler. If you try to roll the entire mainsail onto the boom you'll be cursing and cranking for 10 minutes and the sail will look like crap.

My CAL has an internal roller boom (Stowboom).. it works fine but the thing needs a good shot of silicone from time to time inside, and it is imperative to hold tension on the halyard so the roll is tight, or it won't all fit
