Series 55 Ratchet Orbit Block™ - Single - Swivel Head - Auto & Manual

Automatic Ratchet Block
Now you can enjoy the flexibility of setting up your ratchet blocks to suit yourself. Ronstan is the only company that offers a ratchet block with both auto and manual engagement modes. In the auto mode of the ratchet mechanism engages when load is applied, but switches off when it's released. This lets the sheet run out smoothly and freely-great for rapid easing of the sheet and for gybing asymmetric spinnakers. In manual mode, the ratchet mechanism can be switched on or off as required. This is the preferred mainsheet set-up for may top sailors. Try the block in both modes and see which you prefer - you really can't go wrong.


Awesome Ratchet Block Holding Power
Quite simply, Ronstan Ratchet Orbit Blocks™ have the highest holding power available. The sophisticated NC-machined sheave features Generation 2 of our sheave cross-hole geometry. Its holding power is up to 21:1, almost double that of our nearest competitior. The unique sheave design has 12 gripping faces which directly resist loaded line movement. Traditional designes have only 8 faces with an angled resistance to line movement. Our Generation 2 design has straight resistance faces which both distribute the load and minimise rope wear. These faces are offset from the radial line, to draw the rope down into the gripping area when under load.

Features:
  • Up to 20:1 holding power
  • Smooth easing of sheets
  • High performance cleating
  • Swivel shackle head for unlimited block rotation.
  • Stainless steel shackle head for ultimate durability and compatibility with harsh fixing points.
  • Automatic & manual ratchet block

It was easy to read
Format: Paperback
This book is written so I can refer back to it from time to time. It was easy to read, not a lot of jargon. I am really enjoying reading this book, Extraordinary Relationships: A New Way of Thinking About Human Interactions by Roberta M. Gilbert, M.D. It kept my interest. It is only 168 pages, plus a few more pages that has reading notes, epilogue, a glossary, and of course the index. The book about developing yourself so that you can further develop your relationships. kudo to the author and her mentor.

A bit repetitive
Format: Paperback
The Family Systems approach makes a great deal of sense and is very helpful. But this book seems to be somewhat formulaic - every case looks the same.

Extremely enlightening!

A psychologist recommended I read this book as my daughter and I were having issues. Wow! What you'll find in this book will change your whole thinking about relationships with family members. Very enlightening as to why we all behave as we do and what affect our behavior has on the development of our children. A MUST read for every parent. I bought a copy for each of our children and grandchildren to read.

Some good advice
Format: Paperback
Roberta Gilbert's "Extraordinary Relationships" offers useful advice for dealing with family relationships couched amidst an examination of systems theory. Although it is more technical than a lot of self help, it can be used by a general audience. Gilbert examines the theory of Murray Bowen, who countered notions of individual psychology (like those of Freud) with the theory that personality develops as a result of a family unit. The nuclear family, like a herd of amimals, reacts against each other, speaking a common language that is known only to them. Children raised in that family then detach from the family to form their own adult relationships, where dynamics may follow the family system. In order to heal adult problems, the author offers some practical advice, like taking the time to observe old patterns as they crop up (family Christmas fights come to mind) with the dispassionate mind of an observer. The author states that individuals will better be able to understand family dynamics and their role in them by doing this. I've read this book twice, and it has helped me better understand my family, and my role within it. I would recommend it for those who are seeking to better understand their family of origin, and what they can do to improve their present life through understanding the past.
