The KSW40 is an innovative and very (very) efficient 4-speed automatic winch : 2 speeds identical to other winches on the market PLUS 2 additional extremely fast speeds. The speed change takes place as on a traditional winch by changing the direction of rotation. The winch automatically returns to 1st gear when you release the tension. The KSW is more of a winch dedicated to sailors.

When maneuvering, the difference is just incredible : the line is “swallowed” 6 times faster than a winch of a similar size. Many sailors have already adopted it and are gaining ground with each maneuver : sending of sails, gybes, tacking, … These manual winches are so quick that you no longer have to pick up slack in the line on the fly. The maneuvers are safe and fast, the sails wear less, the boat loses less speed, … 6 times faster = 6 times less crank turn to give. The KSW is simply the fastest winch on the market !

– 2 winches in 1 : 2 standard speeds and 2 additional very high speed speeds
– 6 times faster than other winches on the market (equivalent headstock size) : 1 turn of the crank = 65 cm against 15 cm (30 cm on a 3-speed winch)
– The fastest winch on the market. No Equal for Equal Size
– A formidable weapon for any racer looking to maneuver faster.
– Listening is never resumed by hand. A saving of precious time in turns and gybes for solo skippers or small crews.
– A benchmark on many Class 40 and sailboats racing with small crews (Transquadra for example)
– 4 automatic speeds. Speed change at each change of rotation.
– Available in 3 sizes : 40, 46 & 52
– Applications : Tacks, jibes, sending of sails
– Advantage of a faster winch :
– Speed, fluidity and safety of the maneuver (the ropes remain on the self-tailing without having to take up the “slack”
– The sails wear less for a long time and are damaged less (stability of form and longevity)
– All the winches are equipped with self tailing – Made of aluminum, hard anodized and black.
– The materials chosen limit corrosion and component wear.
– Easy to maintain.
– 5 years warranty

Good quality and design, but...
Size: Medium, Color: Black(windmill)
The design, fit, and feel are nice, and I'm glad I used the sizing chart within the pictures because typically I have to buy a large in other brands. However, the collar is unsupported and the fabric is like others have said (thin, silky, a little like a shower curtain, and a little like a disco shirt, though surprisingly not stretchy). Not necessarily bad, just unexpected, and pleasantly light. I bought the white polka dot and the gray diamond print. The white was a tiny bit see through and the gray has a very subtle color change throughout the fabric undulating slightly lighter to slightly darker, which I did not notice from the pictures, but was nice. Unfortunately, the pocket fabric didn't switch lightness and darkness the same as the rest of the shirt, so the one I received had a dark splotch right next to the lighter pocket fabric making it look like a grease stain on the center of the shirt. The two were also slightly different in size even though they were both listed as the same size (medium). The white one pulled across the chest and had more fabric on the sides, the grey one fit beautifully with a nice taper, but it had the "stain." I did not wash mine or try to get the wrinkles out, but the crease of the fabric upon arrival is very prominent, and I would imagine it is hard to get out. All-in-all, I didn't love the shirts, so I returned them. But the fabric was nice, thin, and comfortable but I wouldn't say cheap. The shirt was a little more casual with the unsupported collar which is just good to consider. And there were some minor inconsistencies with sizing. I would have kept the gray had the pattern lined up better and perhaps I just got the one bad one.

I love these shirts!
Size: 4X-Large, Color: Blue Combo
These shirts are great! They’re super comfortable, super stylish, and they fit me! I’m a fat guy and they make me look great. Here’s a tip if you’re fat like me. Sit down in a chair and measure around your biggest area, then use that as your “chest” size on their charts. Order whatever size is just a little bigger than your measurement. Always check the charts because they’re not always the same.

Nice looking shirt
Size: Large, Color: Black
A very nice shirt. Bought it for a “polka dot” dance so needed a polka dot shirt. But, it’s nice enough to wear for going out or golf. Yes, the inside is white but it’s not distracting. The medium was just right. Sometimes wear a large.
