Product Information
Core Blocks™ are a true all round solution. A tuned 2-stage bearing system provides excellent performance across the full working load range with an integrated thrust bearing feature and the resilience to handle high dynamic or static loads. Acetal sheave, alloy cheeks and stainless fixings complete the durable package. For reliability and a long service life, these blocks are the right choice for sheets, halyards and control line applications for cruising and racing.
Universal Bearing
Dynamic and high static load performance
The Ronstan Universal Bearing incorporates our proven 2-stage bearing system
Stage 1 - Under moderate loads, Acetal ball bearings ensure minimum friction.
Stage 2 - Under heavy loads, where deformation of ball bearings alone would result in increased friction, a sliding Acetal bearing on a polished stainless steel race takes over, maintaining low friction performance.
Additionally the ball bearings are configured to act as a thrust bearing between the sheave and cheeks, preventing the sheave from rubbing on the cheeks and causing friction when the line lead in and out of the block isn’t perfect. Particularly important for cheek blocks.
Alloy cheek plates
Block cheeks are manufactured from the highest quality alloy for maximum strength. Material optimization and the cut-away design minimizes weight and allows easy fresh water rinsing of salt and debris from the bearings. Cheek design has been further styled with flaring at the block throat and reduced gap between the cheek and sheave, minimizing rope wear.
Universal head
The head assembly incorporates a brass bearing washer to provide smooth 360° rotation of the post and shackle. A set screw arrangement allows the head to be locked at 0° or 90°.
Shackles are high quality forged grade 316 stainless steel.
Suits pre-spliced lines
Removable becket pins allow fitting of pre-spliced lines. The flush fit becket pin head is kind on deck surfaces and won’t snag lines.
Applications
Ideal for use on mainsheet, spinnaker sheet, vang, halyard and backstay applications on boats up to 14m (46ft).
General applications on larger yachts.
Alloy sheave models are available for use with wire.
Materials
Sheave: U.V. stabilized acetal or anodized aluminum (AW models).

Solid Omegaverse!
Format: Kindle
4.5 strong stars!🌟
Overall great story solid omegaverse. I love how they’re fighting their instincts. Lots of spice, TONS of slick and heated moments.
**Slight spoiler sort of**
I was nervous reading this for pretty much one reason and that was the other “O” listed. I knew it wasn’t another female and I would have been happy/fine if it was but the concern lay in not knowing or being guaranteed the smexual preferences of our three alphas so realistically this gave me anxiety on how the dynamic would work. Anyone who has read omegaverse knows there’s usually one omega in each pack. My fear was the male omega connecting only with the female omega and that dynamic doesn’t wholly work for me. To me, the male omega needs the alphas as well so I was relieved with how this turned out.

Good plot but definitely slow burn
Format: Kindle
⭐️⭐️⭐️⭐️.5|🌶️🌶️🌶️🌶️ (not a ton of spice scenes for an Omegaverse)
The plot, character development, scene progression, and action throughout the story was done really well. I did wish there was better pacing for the spice. I felt like the big spice was really rushed. During some scenes the story was a little hard to follow. I think some parts could’ve been cut. Overall I would read more from this author! 💖

omg loved the story
Format: Kindle
I’ve been in a reading slump DNFing so many books and finally found a story to keep me captivated… now with that though there were still some parts that were a bit of a struggle like Tatums struggle with the past trauma she dragged that on for ever I get it pasts are hard to overcome sometimes. But honestly it was easy to get over it falling in love with all these little psychos 🤣🤣🤣 absolutely loved Kodi’s obsession with getting Easton even though he doesn’t know him but smells brownies everywhere and missing the mark it was hysterical.

Omegaverse with rival families.
Format: Kindle
Tatum is trying to raise enough money to treat her omega mother who has fallen catatonic due to the death of her mate. To make the money she needs she agrees to work at a gentleman's club scantily dressed. There she meets the twin Hayes brothers, Declan and Kodiak, what she doesn't know is that their younger half brother is the high school sweetheart that ghosted her after helping with her first heat. Tatum also meets Easton, the mysterious male omega that pops into her life but she finds herself strongly attracted to.
I enjoyed all the characters, even those that were not major characters, the plot was good, the storyline was well done. I would recommend this book if you liked Omegaverse stories, mafia storylines, and good romance with why choose.

Loved it!
Format: Kindle
Who doesn’t love morally grey men obsessed with their omega who isn’t afraid to call them out on their unacceptable behavior and make them grovel?
Tatum really is a survivor through and through. She is willing to do anything to get her mother the help she needs, even deal with the man her broke her heart.
If you love brothers playing jokes, crazy stabby omegas and rich men being told no, you will enjoy this book. Great spice and great ending.
