The A2024 is our go-to triple 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.

Triple blocks are generally used in systems such as cunninghams or vangs, to give a larger purchase system.

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.

Becket – Our 20 & 30mm blocks offer a large central rivet which not only reduces the overall weight but also offers a rope friendly attachment, perfect as a tie-off point when being used in a cascade system.

UGH SO GOOD!!!
Format: Paperback
Such a good book! The way the story is written and how the characters are portrayed leaves you wanting more! A tad bit of a slow burn but so so good and worth the wait! Personally I bought both the book and audio book because I couldn't put it down! This book had me (A man) kicking my feet like a little girl and holding back tears throughout the story. I just love love and this story is just so beautifully written!

Slow burn with a sprinkle of fantasy.
Format: Kindle
It was alright. Written well. Story was decent. But it just lacked something. It's the slowest burn I've ever read, which is fine. I felt like the knight (main character) was kind of weak and whiney… And I expected the strength of a knight! The first chapter is filled with a lot of background information, but then it's like the story doesn't really reference it again. I would have liked a bit more information that first chapter before just heading right into the story in chapter 2. Things could have been explained more in general. There could have been a lot more detail and explanation abiut the fantasy side of the book. It was just like a straight romance with a sprinkle of fantasy. Overall, it was decent, but I probably wouldn't recommend it to someone unless they asked specifically for a slow burn with a little bit of fantasy. I received an advance review copy for free, and I am leaving this review voluntarily.

A Forbidden Romance With Teeth
Format: Paperback
First off: I loved the couple. Della, our acting princess, and her sharp wit and determination to survive were a refreshing change from the damsel type princess. Galeon was a woman of honour and yet so head over heels with the fake princess that she can't keep away. Birch does a great job of building a magical world and drawing you into it so that you kept turning pages until the end. And that page-turning was also spurred by the slow burn will-they-won't-they romance between the heroines who had much to lose if they crossed the line. I've purchased all three novels and will review Her Blushing Hero just as soon as I've finished.
