Allen Blocks

Allen blocks, also known as pulleys, are all high performing and use a patented Dynamic Bearing technology. Allen also invented and use a patented Ultra-strap technology, a very narrow strap of high strength stainless steel, which can be lashed without fear of line abrasion associated with blocks of traditional strap construction. Throughout the range you can be assured of quality, innovation and performance.

Allen blocks are designed and made here in the heart of Essex where we are based.

It's been worth the wait

Having thoroughly enjoyed a week's training at the Lyme Regis Sea School this phrase is indelibly printed on my sub conscience (the instructors will be pleased to learn) so to have this mug to remind me each morning at breakfast is a treat.

The Zihk Sailing kit bag is very well-made and much more practical than my rucksack. The ordering process was slick and the delivery was fast. I’m looking forward to my next sailing trip with this product. Good price too, thank you!
