So I am definitely the odd person in the sewing world who cuts everything with my scissors. I’ve been a sailmaker for 30 years and we cut paper, Mylar, Kevlar, carbon fiber, fabric (of course), rope, tape, adhesives, you name it. I’ve been using the same pair for 20 of those 30 years as well. We do get them sharpened but not all the time.
Dyneema is the one thing that will mess up your scissors though. My buddy at work had a dull spot on his that wouldn’t sharpen from dyneema webbing. We ended up getting a special pair for that and Kevlar, with micro serrated teeth.
I will say though that a person’s scissors are sacred, you don’t touch another sailmakers pouch and tools. What they do with them is their business, use your own tools.
Mind if I bug you with questions about sail making? That sounds like a super interesting job!
For sure! Though I apologize if I don’t answer right away! I will answer though.
How do you get into a job like that? I figured they would mostly be made by machines nowadays.
What’s the biggest sail you’ve worked on?
Best/worst material to work with?
What kind of equipment does your job require?
You mentioned a knife but I’m guessing it’s not a common knife. I’m imagining more of a hook shaped blade to pull easier, but would love to know if I was wrong

Thanks a ton for the answers!
I’m honestly unsure where my brain got the knife thing if I’m being honest.
One more question for you if you don’t mind -
How’s kevlar to work with?
Haha, my brain does the same thing all the time.
Kevlar is a funny one for me as I’m now allergic to it. Yay occupational disease! If I have to use it for a quick job it’s fine, but anything longer than an hour I get what feels like a sunburn. Usually on my arms and cheeks, basically where I touch when I push up my sleeves or whatnot. Doesn’t get red, just feels like a bad sunburn. One of the ways it’s used is in big rolls with an adhesive backing, for patches. So we’re not really sure if it’s the Kevlar or the adhesive, but I can use any other product with an adhesive back and it doesn’t happen.
Anyhoo, Kevlar is really tough, so it can be a pain to cut. That toughness makes it great for backing patches or chafe patches. On Genoas we’d use it to make spreader patches. It’s really only used like that on laminate sails. Though I’ve seen Kevlar leech line used on Dacron sails. Another common use is in kayak hulls along the keel for abrasion resistance. It also has a very high melting point and will char more than melt, which also helps with chafe. Its UV resistance isn’t the best so it will deteriorate over time. But racing sails don’t last as long as cruising sails so it evens out. You can recognize it on a sail as it’s a golden yellow.
Edit: I think it’s fallen out of favour over fibers like dyneema and carbon. I haven’t been in that part of the industry in a long time.
The fibers and technology in racing sails are pretty crazy. There’s some neat videos online if you want to dive a bit deeper into it.
A kevlar allergy is definitely an interesting one!
I gotta ask what you mean by patches. Judging by the fact you seem to mostly work on racing ships and other very expensive sailing ships, I’m guessing you don’t mean patches in the sense of filler material to fix holes?
Hey did you follow the americas cup this year?
What did you think of the wingsails / twin skins / no boom configuration?
Hi! I didn’t at all tbh, but your question just made me go on a deep dive looking at the boats. So crazy! I’d seen pics of them but hadn’t looked real close. I have to say, it makes sense for the racing they are doing to have that boomless shape. You’re getting every bit of wind with no waste. Those boats are engineered to the hilt, I can’t wait to see what they do next year. I’m going to watch some videos later, thanks for the rabbit hole!
The race I have been following is the Vendee Globe. The website is so good. I highly recommend!
Vendee global is amazing! I feel like it’s the closest thing to a pure “all rounder” sailing - solo sailors, robust and well-engineered boats that are just smashing it every condition and loving ayvoace as well. I’m subscribed to their updates on YouTube.
So as to the madness of the americas cup - if you look at the sails they each have two wide counter coloured bands on them. when doing boat testing they use upwards facing LIDAR on both sides of the boat to calculate the best sail shape, live, and adjust accordingly. I feel a bit odd about that, I think trimming is one of the fine arts of sailing and to see it automated out is a bit sad. But if you’re doing 45 knots on foils, I guess the fewer jobs the better.
