The A2022 is our go-to double sheave low friction, fast rolling, small pulley. It’s lightweight and strong, making it ideal for dinghies, windsurfing, kitesurfing and anything else that runs smaller diameter lines. 

Our Dynamic range is generally the best choice for applications that require constant sheave movement.

Becket – This block has a becket to make tieing off easier. The becket also helps keep the load central.

Bearings – Dynamic Blocks feature our patented bearing system which uses twin rows of stainless-steel ball bearings running on a stainless-steel rail. This provides a superior load-carrying ability and longevity when compared to other bearing systems which run on a plastic rail.

Ultra-Strap – Our patented Ultra-Strap is used in our 20, 30 & 40mm Dynamic blocks. The Ultra-Strap is unique when compared to other designs because of its coining process. This process strengthens the strap, making it more reliable and hard-wearing as well as making it much more rope friendly than other designs. The Ultra-Strap was the first marine industry block designed to work specifically with a rope attachment.

Cute dress, runs large. I’m usually a true medium but sized down to a small based on other reviews and it fits perfectly.

Skirt portion of dress was awesome!
Size: Medium, Color: Black
Great skirt with pockets. Loved the light cotton fabric. Needed a little more support up top than what the dress could give. Probably better for AA-C bust.

Not what I expected
Size: Medium, Color: Black
Very cute but, the top of the dress is like a stretchy cami, like what we used to wear from the 90'/00's - so not dressy enough for my occasion and I returned it.
