The 40mm Single block is our go-to dinghy mainsheet block. Also ideal for dinghy jib and spinnaker sheeting systems as well as keelboat control lines.

Built with a lightweight composite cheek, rope friendly Ultra-Strap and Dynamic bearings

Bearings – Dynamic Blocks feature our patented bearing system which uses twin rows of stainless-steel ball bearings running on a stainless-steel rail. This provides a superior load-carrying ability and longevity when compared to other bearing systems which run on a plastic rail.

Ultra-Strap – Our patented Ultra-Strap is used in our 20, 30 & 40mm Dynamic blocks. The Ultra-Strap is unique when compared to other designs because of its coining process. This process strengthens the strap, making it more reliable and hard-wearing as well as making it much more rope friendly than other designs. The Ultra-Strap was the first marine industry block designed to work specifically with a rope attachment.

Becket – The 40mm range features a large central hole, which is designed to be used as becket (tying off point).

    Boyfriend liked it, however it has a weird fit
    I got this for my boyfriend as he is a fan of this brand's clothes. I got him small and I am glad I did. Although it looks fantastic on him because he is him, the sweater is strangely long and has a weird tough material to it. It is not exactly soft to the touch, and it has a weird stretch. It doesn't feel like other COOFANDY brand turtlenecks he owns, so I was surprised at how stiff the material was compared to those. The color is also a bit more orange in person.

    Ribbing & AComfortable Fit
    I stumbled onto this brand as the sizes & sizing were very accurate. The ribbed feature is a blessing as it masks, hides, conceals stains & or body imperfections. I'm a 63 year old grandpa who greets outside in the Midwest at church 50 weeks a year. The warmth, the longer sleeve's and the high & roll up, roll down turtle neck is super cozy. The value is, it looks more expensive than it actually was, I have already ordered another in black. I am 5'8 298# with a 63 inch chest 48 inch waist fits with room to spare.

    Very nice turtleneck
    I bought this for my husband as a Christmas present. He loves it! He says it fits well, not to heavy and is very comfortable.
