The main benefits of an extendable gennaker bowsprit:

• Gives the gennaker more clear air  

• Facilitates rapid gybing

• Always ready for quick extension

• Makes for fast and efficient gennaker handling

• Improves performance when gennaker sailing

• Can be fitted to most yachts

• Available in carbon or aluminium

 

Extendable carbon fiber gennaker bowsprit sold as a kit for deck mounting. Fit the two foldable stainless steel pad eyes to the deck in line with the bow bracket (bracket to be ordered separately) and you will have two attachment points for the inboard (aft) end of the bowsprit. The forward pad eye is used when the bowsprit is pushed out and activated. The aft pad eye is for "stand-by" storage, and if required, the bowsprit can be quickly removed and stowed securely below deck. 

The gennaker tackline runs through the bowsprit, entering and leaving via well rounded holes, and then aft to the cockpit.

Add a D-shackle to the outboard end and it will allow attachment of a top-down gennaker furler. Attach the furler, push out the bowsprit and engage it to the foldable pad eye and you are all set for efficient and fun downwind sailing.

The bow bracket is a stainless ring with a low friction polyamide inner lining through which the bowsprit slides into its “active”  position. It must be fixed to a strong and solid part of the bow as it will handle high load, both vertical and sideways. Four different versions of bow bracket rings are available and which one to use depends on the design of the bow. 

The carbon section has a reinforced area which shall be located in the bow ring when the sprit is pushed out in active position. To achieve this, the carbon section must normally be cut in both ends.

By using our digital calculator you can easily determine which dimension of bowsprit/bow bracket you need for your boat.

https://support.seldenmast.com/en/services/calculators/bowsprit_calculator.html

This is based mainly on the righting moment of your boat, the unsupported length (USL) of the bowsprit and the Distance between supports between the bowbracket and the forward pad eye (DBS). 

Important - this product is designed and dimensioned primary for gennakers/asymmetric spinnakers and not for Code Zero sails. A Code Zero is projected to very high load and for the bowsprit to be used, the USL must be drastically reduced as opposed to when used for gennaker.

• Gives the gennaker more clear air  

• Facilitates rapid gybing

• Always ready for quick extension

• Makes for fast and efficient gennaker handling

• Improves performance when gennaker sailing

Student Review
This book is an excellent introduction to the basic principles of insurance. We used this text as a supplement in our Intro to Act. Sci. class. It is very readable, easy to understand. Minimal mathematics required, some basic calculus concepts used, but only briefly. Don't let it's small size fool ya, it has plenty of information in there.

A #MustRead for cybersecurity practitioners
Format: Kindle
Rick Howard's latest book is the ultimate reference for cybersecurity practitioners, making it an essential read for anyone in the field. With his straightforward and refreshingly irreverent writing style, coupled with his profound technical knowledge, Rick has created a narrative that is easy to understand and grasp. He delves into the foundational aspect of cybersecurity, which he refers to as the cybersecurity first principle, which he then it to specific high-impact strategies. The book has eight well-written chapters providing a comprehensive overview of those strategies. Importantly, Rick then offers an up-to-date and thorough exploration of the complementary capabilities (tactical-level tools) that can be utilized to "reduce the probability of material impact due to a cyber event" - the cyber first principle. In the concluding chapter, Rick succinctly summarizes his contribution to the field, stating, "And that's it. Those are all the tools you need to design, build, and enhance a cybersecurity program based on first principle thinking." This assertion highlights the value of his book as a practical guide for designing and improving cybersecurity programs with a focus on first principles.

Absolute must read if you oversee any portion of a cyber security program!
Format: Paperback
I loved this book. The concepts and ideas presented are a great wake up call for an industry that is so focused on blinking light hardware and the next big technological thing...this book challenges the paradigm that you need to strip your security culture down to some very core ideas...then build a solid security program around your security first principle(s). Without that core idea, you're just throwing away money on tools that may not actually be addressing your root needs. Great read for anyone looking to rethink their security program, security culture, and security spend. BRAVO!

Context, Strategies and Wisdom in a single package
Format: Kindle
This was my first book I have read by this particular author. I had spent some time looking for a comphrensive approach to Cyber Security and found many other texts to be lacking. Certain aspects are well documented, but no single source that brought it all together. This is exactly what First Principles brings to the table. As a practicioner that looks for better ways to formulate the objectives of SecOps Use Cases I have found the methods presented in this book to be immensely helpful. I have also given copies aways as a gifts to students who are just entering the field as this is by far the best intro to the long history of Cyber Security that combines the best direction for the future. The historical context that the author brings through first hand experience is beyond a treasure trove. It has been said many times in cheezy ads, but honestly, if you only read one book on Cyber Security make it this one.
