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.

Lightweight, Smooth, and Truly Unscented — My New Go-To Sunscreen
Size: 6 Fl Oz (Pack of 1), Style: SPF 50
This is the first time I tried this Banana Boat unscented sunscreen, and I’m genuinely impressed. One of the biggest things I look for in sunscreen is how it feels on the skin, and this one delivers—it’s not sticky at all and goes on very smooth. It’s easy to apply and absorbs quickly without leaving that heavy, greasy feeling. I also really appreciate that it’s unscented. There’s no strong or unpleasant smell, which makes it much more comfortable to use daily. I’ve used other brands before, like Neutrogena and some higher-priced options, but honestly, this one stands out. It performs just as well—if not better—at a more reasonable price. Overall, this is a great sunscreen that I’ll definitely keep using. Highly recommended if you want something lightweight, smooth, and fragrance-free.

BEST sunscreen on the market
Size: 6 Fl Oz (Pack of 1), Style: SPF 50
This sunscreen is truly the best sunscreen on the market. I have now bought 4 bottles, and plan to purchase more. It is extremely milky, dissolves onto the skin perfectly, it feels like you arent wearing any sunscreen at all. I tell everyone I know about this product. I also purchase the FACE spf which is even more smooth. I wish they sold this in a giant container, because I apply this everyday !! This sunscreen has made it more accessible for me to apply sunscreen daily, it also has very minimal scent, and never burns your eyes. Personally I will never buy another type of sunscreen again after this sunscreen.
