Tufnol is a traditional laminated plastic material made from phenolic resin and woven cotton or linen fabric. It is strong and light, and provides an economical, low maintenance and traditional solution for sailing boat blocks.
Our Tufnol blocks are manufactured in Holland with solid stainless steel frames and brass bush bearings.
The single Tufnol block, fitted with a fixed bow and becket, comes in four sizes to work with ropes from 10mm through to 16mm.

As master of STS Wutuku a 60ft Traditional sail training Ketch I have in the past found it hard to find historic boat hardware. Although I have so far bought some blocks from CBS the service was great I will try them again for sure
