Item Description

The Sailrite Ultrafeed LSZ-1 PLUS Sewing Machine package features our powerful, portable, straight stitch/zigzag walking foot sewing machine with some of our favorite accessories. This package is perfect for someone who needs an easily portable, heavy-duty machine or for boat owners looking to sew heavy canvas or sails. The Ultrafeed LSZ-1 Plus Package features the Ultrafeed LSZ-1 Sewing Machine (Patent #6499415) in the Industrial Carrying Case, and includes the Integrated Thread Stand and the Flex20 LED Light.

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

Included with the Ultrafeed is the Power Plus Balance Wheel, which has twice the power and size of a traditional flywheel for more slow speed power and control. Turning that wheel and 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, in both forward and reverse. 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.

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.

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!

Could Not Ask for a Better Machine


I have never used a sewing machine in my life but with a sailboat full of projects I thought it was time to learn. The LSZ-1 was a snap to learn and easy to control. The Sailrite videos made the setup process extremely easy to complete and then it was off to the races! The controls are simple and intuitive. Build quality is excellent and all the tools you need are included with the machine.

Mine's been working great for me.


I've had one of these for a few years, with the monster balance wheel option. The machine's been great. I'm surprised how little adjusting I've done, even when switching fabric weights. A partial turn on the tension knob once in a while has been the only thing. My projects have been mostly Sunbrella - sail covers, winch covers and other boating and camping stuff. Some other things with lighter fabrics (curtains, etc). Large model airplane wing bags from quilted fabric. The biggest project was a sacrificial Sunbrella border for the 150% genoa on my 36' sailboat. It's a BIG sail and I made a special table to be able to feed the rolled up sail through the machine. I'm no expert but the machine seems to make things pretty easy so it works out well for me. A couple of boating friends have this same machine and they're really happy with theirs, too.

A little more on my table. I got an 8 ft long x 30" wide portable plastic top table from Costco and put an angle bracket under one long side about halfway along. On that I hang a little plywood shelf with one leg at the outside end and I set the machine on that with the sewing surface of the machine the same height as the table top. It's like a miniature sail loft if you've ever seen a real one. You can slide some fairly bulky stuff around on the plastic table top for ease in maneuvering through the machine. The walking foot does a great job of feeding the material. You just have to keep the bulk of it managed somehow.

I've built a couple of the project kits that Sailrite sells and they've been good practice for an amateur sewer like me:-)



Very prefect

Ultrafeed in the Sculpture Department

by -

I purchased one of these machines for the sculpture department at the university where I teach and was 100% satisfied. For years my students have wanted to utilize sewing for sculptural projects and we've been just making do with hand-me-down machines. The Ultrafeed sews like a champ, especially when we need the walking foot for materials like vinyl and nylon. I would highly recommend this machine to anyone and will hopefully be getting one for my own studio soon.
