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 aluminium 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. 

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.

Great Knee Support
Color: Blue
The 1-inch thickness provides exceptional support and cushioning, making it ideal for a variety of exercises beyond just yoga. The high-density foam used in this mat is a game-changer. It not only cushions my joints but also retains its shape remarkably well. The carrying strap is a convenient addition, allowing for easy transport wherever I go. Plus, the mat is easy to clean, which is a huge plus after sweaty workout sessions. While the extra thickness might not suit everyone's preferences, especially if you prefer a thinner mat for certain poses, I find it perfect for my needs. It strikes an excellent balance between comfort and stability, providing the right amount of cushioning without compromising stability during balancing poses. Overall, the BalanceFrom All Purpose Yoga Mat will become an indispensable part of my fitness routine. Its durability, support, and easy maintenance make it a top choice for anyone seeking a reliable exercise mat for various workouts.

Perfect For My Routine
Color: Black
I am retired military, so exercise has always been a part of my daily routine. Since the pandemic I have had to adjust, which is hard because the gym has the equipment I have become accustomed to. I didn’t realize how different it was working out there as when I started to work out at home on my hard wood floors (no carpet anywhere). I thought it would be easy but the military exercise mat is entirely too thin and was making my tailbone hurt tremendously, so I had to give up my sit-ups and some other ab exercises. This kind of threw a wrench into my routine and I could start feeling my motivation go away. I decided to take a look on Amazon for a thicker mat. I should have done this long ago because I found this one I’m writing about. It’s the shape of any typical exercise Matt except it’s 1” thick. It appears to be made of a type of foam (not bothering to look at the description right now). When I pulled it out I thought I was going to sink in making sit-ups even harder but it’s firm but not hard. I like it better than what is at the gym. Durability will be hard to determine until I’ve had it a while but I’m definitely excited to start back up on my exercises. I recommend this mat if you have hard wood floors, bad back, bad knees, etc. I thought I read some negative reviews about mats this thick because of yoga and balance but I beg to differ. If balancing is part of your exercise routine, then a mat which makes balance harder is exactly what you want. Exercise is supposed to be challenging and you need to work harder to see a difference. If that isn’t your goal or if balance is a medical issue, this may not be the right mat for you. Something you may not think about is I have chronic foot pain and this mat makes it less painful for me to stand or jump. For me, this mat is perfect.
