Brewer 44 - In Mast Mainsail Furling was created by Matt Davis
Just finished a survey and sea trial on a 1990 B44. The boat has Z-Spar mast and boom. During the sea trail, the owner could not get the mainsail to extend all the way out. The best he could get was about 3/4 of the way. I attempted but could not do any better. It appears the sail "snags" or gets jammed near the top while winching it out (extremely difficult to unfurl). It does furl back into the mast, but takes tremendous effort to grind it back in, as well. The sail is 10+ years old. The furling lines were in really bad shape, as were the cars on top of the boom for the outhaul. Were we doing something wrong? The owner sailed this boat all the way from North Carolina, down through the canal and then up to Mexico. He said it would hang-up like that 1 out of 10 times but would usually work after furling it back in and then letting it out again.

Since the mast and boom are made by Z-Spar, is it safe to assume the the in-mast furling mechanism is also a Z-Spar design/product? The schematics I have found online do not match up to this system's appearance.. Can the furling unit be serviced through the very limited access of the mast or would the whole rig need to come done to repair/replace? Furthermore, can a new sail be bent on without taking the mast down? Any idea on cost of a new in mast furling mainsail? Could the mast be retrofitted back to a conventional sail?

I would greatly appreciate any feedback, as this is what will make or break my decision of becoming owner of this particular Brewer 44. My biggest fear is that the whole furling unit/sail are shot and I would have to replace the entire mast/sail setup, which I certainly cannot afford to do.

Thanks,

Matt Davis

Matt,
Sorry to weigh in so strongly. I highly recommend hiring the services of a rigger to assess the condition of the furler. Main mast furlers are notorious for problems. In addition, when you keep in mind the 1st LAW of WBSailboats, never assume your installation is the same as the next boat - similar, but not the same. You are correct that a problem may be expensive or impossible to fix. Coupled with your determination that maintenance has been deferred, identify the cost of repair and proceed with caution. I don't know your location. I have experience with a couple of good riggers but limited to Annapolis and mid-Florida. Good luck, and keep us posted.

Greg is certainly correct that no two of our boats are identical. I have a 12.8. You're going to find my story hard to believe and it may be irrelevant but I'll shar it anyway for what it's worth.

When we sea trialed my boat the in mast furling was almost impossible to roll out. We bought her anyway with an allowance for fixing the problem. The furler was so hard to roll out that my 270 pound 6'3" son could barely pull the sail out.

When we got the boat home to my own yard the rigger began his diagnosis by grasping the sail at the clew and pulling. It was a little stiff but did pull out. He then worked his wY along the out haul all the way to the winch on the cabin top. He found friction at every block. His recommendation was that we replace all the blocks with ball bearing blocks and reduce the diameter of the furling line one size because it, too, was binding. He also adjusted the angle of the boomto make sure the sail didn't bunch up when it was furled. Believe it or not, the combination of these small fixes eliminated the problem

My system is a LiesureFurl so my experience may be no help.

Good luck.

Hi Greg, thank you for your input. I am going to try and source a rigger. I will be sure to update the outcome.

Hi Jack,

Thanks for taking the time to give a recap of your experience. That is very interesting that you experienced similar conditions to what we did. I am sure that there are elements of friction going on, probably even more than we know about. I will keep the ball bearing blocks in mind if we move ahead with the purchase. The wife really loves this boat so how can I say no?!

And don't forget the diameter of the furling line. That made a big difference, too. Try the idea of starting from where it comes out of the mast and seeing where you feel big resistance. If it is in the mast you have one kind of problem. If it is downstream it may be an easy fix.

My Brewer has Hood in-mast furling. 2 comments.

1. Important to keep the boom elevated at the aft end so the sail doesn't wrap directly on top of the wrap underneath of it, rather you want a spiral like you normally see for the head sail. I think your photo shows this, so this may not be your problem in this case. Use the topping lift before starting to furl the sail. About 5-10 degrees from horizontal.

2. You want a tight wrap of the sail around the foil inside the mast. You must keep tension on the outhaul while pulling on the furling line to wind the sail in. this is a delicate balance of tensions. If you don't keep tension on the outhaul, the wraps will not be tight, but loose with gaps, which cause problems the next time you try to pull the sail out.

Once we got these 2 things figured out, we have not had any problems.

It sounds like one or both bearings on the furler are shot. When the sail is furled in the diameter of the sail row is largest and when you start to unfurl the diameter reduces which results in a smaller moment force to unwind the sail. I would find out first which or both bearings are bad by placing a observer at the upper bearing and someone at the lower bearing with 1more at the out haul. Try to unfurl the sail If the lower part of the curler rotates minutly with out the upper rotating it is the upper bearing if both ends move at same time suspect lower bearing or it may be both but the chance of that is slim

Well, we are proud owners of a 1990 Brewer 44!

We were able to fully unfurl the sail after repeated attempts. We then lowered and removed it. Bearings seem to be just fine. It was the actual sail that looks to be the problem. After getting it down, we noticed two considerable tears on the leech that are in the same area as where it would jam. I am hoping after a good cleaning of the furler, a new mainsail, new boomcar and track, and new lines, we will be back in business! Thanks again to all who commented. - Matt

Great news. Congratulations! Don't forget the individual blocks. We and our surveyor thought we needed a new track and car but we didn't.
