The Sailrite® Ultrafeed® LSZ-1 PREMIUM Sewing Machine With WorkerB® Power Pack is unmatched in power and portability. For the first time ever, experience unrivaled power and control in a portable machine. Sailmaking, canvaswork, upholstery work, leatherwork and hobby sewing — the Ultrafeed will elevate your sewing and deliver professional results like never before.
What Is an Ultrafeed®?
The Ultrafeed LSZ-1 (Patent #6499415) is a portable heavy-duty sewing machine that performs both straight and zigzag stitches. The Ultrafeed is extremely versatile. It has the ability to sew incredibly thick, dense assemblies as well as lightweight home fabrics. You can also easily adjust the speed control dial for stitch-by-stitch sewing or faster, production-level output. These features, and many more, make the Ultrafeed the perfect machine for both beginners and seasoned sewers alike.
The body and internal components are all made of robust, high-quality metal, making it a machine that will deliver exceptional results year after year. Assembled and tuned by hand at our Indiana facility, each Ultrafeed must meet rigorous quality standards. Your Ultrafeed is examined and tested by Sailrite-certified sewing technicians before it’s packaged and shipped.
When you buy an Ultrafeed, you get more than just a machine. You’ll receive Sailrite’s unparalleled customer support and constantly expanding instructional videos. Sailrite is a family-owned and -operated company with over 50 years in the DIY industry. Your Ultrafeed makes you part of that family.
What Can It Sew?
In short, almost anything. The Ultrafeed powers through the heaviest materials and thickest assemblies you can fit under the presser foot. The Ultrafeed LSZ-1 can handle all sails for most 35-foot boats. For larger boats, it will depend on the weight of the sailcloth and the size of the sail. Its sewing capabilities have been proven in up to 10 layers of thick material, but it’s versatile enough to sew through lighter home fabrics as well.
Check out what it can sew:
- Heavy canvas
- Vinyl fabric
- Clear vinyl window material
- Upholstery fabric
- Soft to medium leather
- Lightweight home/hobby fabrics
- And so much more
Let’s Talk About Power!
The WorkerB Power Pack is Sailrite’s all-new motor system exclusively found on Ultrafeed PREMIUM packages (currently 110V only). Here are some key features of the WorkerB Power Pack:
|1/4 Horsepower Motor||The most powerful motor found on portable sewing machines, the WorkerB delivers 2.5 times the power of other portable motors.|
|Power Boosting Technology||When the machine encounters resistance from changes in fabric thickness or density, the control box provides a boost in torque to power through.|
|Speed Control||Easily adjust the maximum sewing speed with the dial on the control box. Whether your comfort level is stitch-by-stitch precision or 638 stitches per minute, the WorkerB provides maximum power.|
|Added Safety Features||An on/off switch allows you to shut the motor off with the machine plugged in. If the foot pedal is accidentally pressed, the machine won’t run and the needle won’t move. This is a great safety feature if you have small children or pets.|
I’m a Beginner — Is This Machine for Me?
Don’t be intimidated by the robust look of the Ultrafeed. This is a great beginner sewing machine. We’ve made the Ultrafeed intuitive and easy to learn. Plus, as an Ultrafeed owner, you have access to the best tutorial and support videos on the market. And our full-color, in-depth guidebook covers everything you’ll ever need to know about your machine.
Take a look at some of the features that make the Ultrafeed a perfect beginner’s machine:
|EZ Set™ Stitch Length Plate||Easily adjust your stitch length for precise, consistent stitching in both forward and reverse.|
|Monster® II Balance Wheel||We all learn at different speeds, and the Monster II delivers the ultimate stitch-by-stitch control so you can sew as slowly as you need to. It also comes with a hand crank for sewing without electricity.|
|Walking Foot Technology||The machine feeds for you, you just have to guide the material. This way, you can focus on what you are sewing.|
|Flex20 LED Light||It sounds simple, but good lighting can make or break a project. The Flex20 provides bright, concentrated light, and the flexible neck lets you position the light right where you need it. With the WorkerB Power Pack, we’ve built an outlet directly into the control box so you won’t have to find yet another outlet near your sewing station.|
|Posi-Pin® Safety Shear||This patented sacrificial pin (Patent #7438009) protects your machine from damage. If you sew over something you shouldn’t, the pin will break and your machine will stop operating in order to protect the machine. Pulling the pin out also makes the machine stop working, which is an excellent additional safety feature. As an added perk, it also makes winding bobbins quick and easy. To learn more about our patented Posi-Pin® Safety Shear, read "The Ultrafeed & Posi-Pin: The Perfect Power Couple."|
|Sailrite Support||We’ve got hundreds of free videos to help you learn how to do everything from changing the needle to sewing your own pillows and cushions. Whether you’re troubleshooting your machine or in need of project inspiration, our specialists are available by phone, email or online chat to help with whatever you need.|

|High-Quality Construction||Quality begins with the machine’s foundation. The Ultrafeed’s cast iron body houses the all-metal internal components for long-lasting performance.|

How Is the Ultrafeed Different From a Home Machine?
Power is the name of the game. Where home machines lack power and control when sewing through multiple layers, the Ultrafeed delivers — every single time. Its unique ability to sew with slow, stitch-by-stitch precision in thick or dense materials makes it an industry game changer. The robust, all-metal internal components won’t wear and break down like plastic parts in home machines, which means less time fixing and troubleshooting your machine and more time sewing.
Where Is the Ultrafeed Made?
We pride ourselves on our hands-on dedication and commitment to our proprietary sewing machines. That’s why each and every Ultrafeed is assembled, fine-tuned and inspected by our highly trained machine technicians at our Indiana facility. We even include sewn-off samples of material proving that the machine has been tested for quality assurance. Every Ultrafeed is thoroughly examined and signed off by one of our senior technicians who has worked in our sewing department for at least six years and has passed a rigorous training program.

Why Should I Choose an Ultrafeed?
The Ultrafeed is a groundbreaking piece of sewing machine technology. No other portable machine comes close to comparison. But don’t just take our word for it! Read what verified Ultrafeed owners have to say about their machines:
"I waited a long time to purchase this machine, but should have done this years ago. Many projects I passed on could have been accomplished easily with the LSZ-1 and the great support of Sailrite. Don’t make the mistake of hesitation. If you are thinking about purchasing a machine, you already need this one." – Mike K.
"I sew bike bags so I am using technical fabric mostly, very slick and laminated. The walking foot is the best of its kind. And all the webbing and heavy duty zippers I use don’t stand a chance, especially with the hefty fly wheel. If you are thinking, “will this work for my application even if I don’t sail?”, then throw that thought out. I was blown away by the results I’ve gotten. ... Thank you Sailrite team, for being the epitome of customer service." – Garrett
"Haven’t sewn a stitch since 1988 and watched videos and started sewing my sling chair replacements. No problems at all. Love my machine and am looking forward to more projects. Your videos are amazing and the book is very detailed. I’m very happy I purchased the LSZ-1 package, as the extras are so simple but so effective. I love that magnetic guide! The LED light is bright and can be put wherever I need it. The case is very rugged and fit and finish is perfect. The machine just makes it effortless for a novice like me to sew beautiful stitches." – Tom R.
"The LSZ-1 is a significant investment, my only advice is to make it earlier and get working on those projects. Being able to breeze through 4 or 5 layers of canvas makes a huge difference to the time taken and the quality of the stitch." - Nils S.
"When I bought this portable sewing machine, I was expecting a great machine. ... What I didn't expect were all the great support videos. I have a great appreciation for the way they guide you through tune-up and maintenance procedures. After your purchase you aren't left to fend for yourself. Even if the machine never goes out of tune, I am confident with the knowledge that Sailrite has shared with me. Thank you." - Gerald B.

Ultrafeed Sewing Machines are assembled in the United States with components from the United States, Taiwan and China.
WorkerB Power Packs are designed to work on inverters/generators of 400W or more of the Modified Sine Wave or Square Wave types. Pure (or Digital Synthesized Wave) Inverters/generators can disrupt the “phase cutting” technology of the WorkerB since they hide high-frequency current in the waveform.

Haven't had a chance to use it a lot yet but think it is going to be really great.
I have been looking at the Sailrite machines and youtube videos for the past three or four years. The canvas on my 1977 Islander32 sailboat is beginning to show its age. Last season, much of the thread securing the sacrificial cover to the roller furling genoa gave way. After a tedious attempt at hand sewing the cover back on, I decided it was time for a new Sailrite machine. The Ultrafeed LSZ-1 Premium machine made short work of the repair. The machine is a solid workhorse and I hope to put it to use making a winter cover and replacing my old dodger and bimini. Thank you.
It has power to handle tough jobs. Well thought out heavy duty design. Support is real, not someone on the phone that you can’t understand or understand your issues. USA
I love my machine. It does just as advertise. I can now take on any job.
I started sewing my own cloths when I was 17 so I knew the basics of a sewing machine. The Sailrite is a hundred times better than my mother's home machine. I have repaired all the broken stitches in my dodger and Bimini and made an awning for my main cabin hatch. I'm making plans to replace my dodger windscreen and eventually replacing all the enclosure panels. The Sailrite has given me a new way to spend the days when the wind is uncooperative and I can't sail.
I'm bummed it to me so long to buy a sailrite.
I have only had my sailrite for a week and I love it. I'm still watching videos on how to operate it properly and working along with the videos. I have been sewing since 1976 when I started in 4-H and I wish I would have purchased a sailrite many years ago. It is so smooth to operate.
Sailrite is that absolute best company. Incredible customer service!!! And my LSZ-1 is amazing! I love this machine. Thanks again to all the Sailrite team, and keep up the amazing Customer Service, you really stand out as a top company to deal with.
Enjoying the machine and all of your learning videos.
