Item Description

The Sailrite Ultrafeed LSZ-1 PREMIUM Sewing Machine package features our powerful, portable, straight stitch/zigzag walking foot sewing machine loaded up with all of our best accessories. This package is perfect for someone who needs an easily portable, heavy-duty machine, for boat owners looking to sew heavy canvas or sails, or for the sewer who wants all the bells and whistles. The Ultrafeed LSZ-1 Premium Package features the Ultrafeed LSZ-1 Sewing Machine (Patent #6499415) in the Industrial Carrying Case and all these great accessories:

  • Monster II Balance Wheel
  • 1” Swing Away Binder
  • EZ Set Stitch Length Plate
  • Integrated Thread Stand
  • Flex20 Light
  • Deluxe Magnetic Sewing Guide
  • Kickstand
  • Left Roping Zipper Foot
  • Cording Foot Set for Large Welting
  • Needle Assortment Pack
  • Elastic Protector Strap

The Ultrafeed LSZ-1 Sewing Machine excels in performance and versatility, sewing in both straight and zigzag stitches. Built with the toughest, most reliable parts, the Ultrafeed is designed to make sewing through heavy materials like sailcloth, heavy canvas, denim, and upholstery fabrics easy (tried and true in up to 10 layers of heavy canvas and 8 layers of Dacron sailcloth).

Double the Power

With the Ultrafeed Premium Package you not only get the standard Power Plus Balance Wheel, but also the extra large, extra powerful Monster II Balance Wheel. The Monster II is a solid 7 lb. nickel-plated steel balance wheel with twice the size and power of a traditional balance wheel. It also comes with a hand crank and creates enough momentum to sew even heavy fabrics without electricity. Powering the machine is a 110 VAC motor (10,400 rpm at 1.5 amps) and a cogged belt and pulley drive system. Operate using the fully grounded, variable speed, electronic foot control.

Patented Posi-Pin

Sailrite’s patented Posi-Pin (#7438009) Clutching System provides 100% power transfer from the balance wheel to the needle. This unique system keeps the clutch from slipping while sewing heavy, hard to penetrate fabrics.

Simple, Straight Forward Sewing

An extra wide (19mm) zigzag mechanical walking presser foot works with the feed dog to pull thick layers of fabric through the machine at consistent speeds for symmetrical stitching. The EZ Set Stitch Length Plate helps to keep stitch length consistent when switching from forward to reverse. Switching directions is made quick and easy by the spring loaded stitch length lever.

The presser foot features a built-in welting tunnel for sewing piping and a needle positioning lever moves the needle left, right and center so you can sew marine zippers without changing the foot. For those times when you need the needle even closer to what you are sewing or you need to sew extra large piping, this package includes a left roping zipper foot and a large cording foot.

Conveniently Portable

The Ultrafeed is built to be tough enough to go wherever you go. Move it around your home, or take it in your boat or RV! The heavy-duty Industrial Carrying Case is a durable, reinforced carrying case that protects your machine so you can sew and store it anywhere. The Integrated Thread Stand attaches directly to the case’s base and swivels for convenient use and quick storage.

Included with the Industrial Carrying Case is our Elastic Protector Strap. This courtesy add-on helps to protect delicate fabrics and clear vinyl from snagging or scratching on the latches of the case. The strap snaps directly onto the case via pre-install snaps.

Sewing Capabilities

The Ultrafeed features a 3/8” high foot lift and a best-in-class needle bar stroke, so you can sew virtually anything you can squeeze underneath the foot. Set the variable stitch length up to 6 mm in straight stitch and up to 5 mm in zigzag width and you’re ready to go. The Ultrafeed will easily sew through fabrics like:

  • Heavy canvas
  • Sailcloth
  • Upholstery fabrics
  • Denim
  • Vinyl
  • Window material
  • Soft leather
  • Drapery material
  • And more!

Sewing Along!


Happy to finally have one of these awesome machines. I have a ton of projects but I have already paid for the machine by just finishing a bimini for my Catalina.

Thanks for Sailrite Ultrafeed LSZ-1 Premium and videos

by -

I have been using the sewing machine for multiple projects on our sailboat. I never had experience before but with this machine and the videos I have been able to make sail covers, hatch covers, winch covers, redo the cushions, make pillows, make an entire enclosure, make sheets and blankets to fit the v-berth and many more. Thanks to great equipment and great videos.

Good machine!!


Great machine, never sewed before but I have very definite ideas how I wanted my sail covers to fit, the machine has the "skill" built in so my amateurish attempts came out good!

A Non-traditional Review


First of all I would say as a disclaimer, I did not use this machine for more than 1 hour. Ok, that said, let me say why. It is a machine not meant for anyone hoping to transition from one needle to another without having to use a screwdriver, it is not meant for anyone who doesn't have strong arms to turn the monster wheel. I was in tears by the end of using this product, but that's because it just wasn't for me. Industrial sewing machines in general as it turns out are not for me. So- why the 5 stars? Because it is exactly as described, it is high quality, it essemblea relatively easily if you follow the instructions. I would say to anyone who likes industrial style sewing machines, to make sure to get the kickstand or your machine will want to fall over when you need to reload the bobbin. I know that this is a non-traditional review, but it's my experience, and maybe it can shed a little light for someone looking to buy. Also, I give it 5 stars because the customer service in returning it was excellent. The representative I emailed back and forth was understanding and walked me through the process without any guff. I had to pay for shipping both ways which isn't refundable, but I consider it lesson learned. I was really impressed with Sailrite, and will continue to buy other products from them.
