2:1 halyard block for Seldén CX45, CXr45 and CXe45 Code Zero furler.

Machined and hard anodized aluminium block with captive pin. Acetal sheave.

To boost the performance when using a Code Zero, the halyard load must be higher than what normal halyard boxes and stoppers can handle. Therefore, a 2:1 purchase needs to be arranged by fixing the dead end of the halyard in the mast and letting it run
through a block attached to the halyard swivel. Position on the mast must be specified by Seldén. In most cases Code 0 sails need to be hoisted lower than gennakers and spinnakers. 

This block is also ideal for a 2:1 purchase on the main halyard.

Best Muclucs I've every owned....GREAT PRICE!
These things are so comfortable and warm. I sleep with them on because I like to have my feet out of the covers. Not too warm...just right. Great quality and fit with a non-slip leather-like sole. I'll keep ordering these ahead of time to make sure I'll always have a fresh pair when I wear them out. I wear them EVERY NIGHT and keep them on all morning. Life-changer! The BEST EVER!!

Great for indoor use.
Size: 10-11, Color: Cable Knit Navy
I bought a pair of these for myself about a year ago and there are plusses and minuses to them. They are comfortable and warm, without getting my feet sweaty or whatever. That's exactly what I wanted. On the minus side, mine ran far too small. I am a 10.5-11 shoe size and the 10-11 is about a half inch too short... my heels are sliding off the back. I am reordering a size 12-13 to try that one. In the take note column, the soles are NOT rubberized in any way. In fact they are like foam, and will absorb water! Also they do not provide cushioning against any kind of rough surface. I think they are perfect for strictly inside the apartment use, but they are not like moccasins or something that allow outdoor use. And I am ordering a 2nd pair after a year so I do like them.
