Snatch Blocks

allen snatch block open

A snatch block is a variation of pulley that has been designed to allow quick attaching and releasing of lines.

They work by having an opening mechanism for the side cheek, there are several different styles available on the market, but our range comes with a simple hinge mechanism that allows the side cheek to open a bit like the famous gull-wing car door or an oyster shell.

Our snatch block range is available with either a 30 or 40mm sheave, both of which feature the Allen dynamic bearing technology. Two rows of stainless-steel ball bearings running on a stainless-steel axle.


Product Feature – Through Deck Bush

A through deck bush, also known as a fairlead, is designed to protect a surface from a rubbing rope or wire, they can also be used to act as a deflecting point.

In most applications, a through deck bush is used to guide a rope through a surface, such as the thwart or strut of a boat. It also offers protection to the material the rope or wire is passing through. 

Through deck bushes are a suitable product for a wide range of applications, so due to the variety, we offer them in many different materials and shapes.

Product Feature – Blue Carbon Tiller Extensions

Working alongside our Team Allen sailors we developed a range of carbon tiller extension. We wanted them stiff enough to give you the right amount of feedback, yet forgiving enough to take a good beating. Although performance was at the top of the checklist, style and looks weren’t too far behind. 

The Blue Carbon range has a dark blue wrap included in the carbon tube, it gives a really nice blue shine in the sun. It’s something that hasn’t been done before in tiller extensions and we feel it really makes the whole thing pop! It will give the end-user the best quality performance as well as making the boat look great.


YS Cast Aluminium Range Discontinued

We have taken the difficult decision to close our foundry, resulting in the discontinuation of our YS range of fittings.

Whilst the YS range has been tremendously successful for many decades, sales have fallen recently as boat builders switched to a more modern alternative. We have also recently received the disappointing news that the company that completed the polishing and anodising of the fittings has fallen victim to Covid-19 and despite an extensive search, we have been unable to source a new supplier who can meet our quality criteria. The investment required in the foundry, anodising and polishing could not be justified for a shrinking demand. Sadly, we have therefore had to make the decision to discontinue this range.

We still have some stock of the YS range; you can find out what we have by clicking here.

However, some of the YS items will now begin a new life with new manufacturing methods and modern looks. The new AY range will be manufactured using our state-of-the-art VMC machines which will produce more accurate and reliable products. We also have the in-house design and machining capability of producing bespoke designs to a customer’s specification.


Our Biggest Block Yet

Around the world, we are known as a company that produces small boat hardware, but this isn’t strictly true. 

Let us introduce to you to “The Big Boy” just one example of what we can do for bigger boats.

This new 150mm block has been designed to fit on the end of an 8-meter hydraulic ram and will be under loads of around 27 tonnes. The Big Boy weighs 5kg and has a plain bearing sheave with ball bearings to cater for side loads. 

Here at Allen, we are much more than just marine hardware specialists. We are engineering experts who work with a wide variety of companies in different sectors, such as; medical equipment, automotive parts, window manufacturing, public and defence sector, theatre, advertising, aviation and much more.

We can work with such a wide variety of clients due to our multiplicity of in-house resources. Which includes our close-knit team of engineers and designers who can work to deliver premium solutions for custom or mass-production jobs. Allen is also an ISO9001 accredited business, which means we are capable of mass manufacturing high-quality products as well as ensuring a high level of craftsmanship is carried out for custom items. 

“The marine sector, from small leisure boatbuilders to large commercial marine engineers all now face the same issue when outsourcing. We are all in the same boat,” explains Liz Adams, Managing Director of Allen. “Sourcing from anywhere outside the UK now carries a higher level of risk to business continuity than it has in the past. Sourcing from multiple suppliers carries the risk they are buying in materials from abroad. The only way to de-risk is to use UK suppliers who, in turn, source from UK suppliers. If you want to see how it should be done, we have produced a video showing how one of our blocks, the A2060Tii, has been designed and manufactured entirely using services we have in-house.

As a British family-owned business, we ensure 100% of our products are designed, manufactured and assembled in-house at our factory in Essex. All our materials, where possible, are sourced from within the UK. We also guarantee a competitive and fair price for any job we undertake.

If you have any custom requirements, big or small, marine or non-marine, don’t hesitate to get in touch to see how Allen can solve your problems.

NEW Inboard End Batten Adjuster

UK sailboat hardware manufacturer, Allen, is pleased to announce an addition to its extensive range of sailmakers products. The A.951-10 – Batten Adjuster.

The new inboard end batten adjuster has been developed alongside one of the world’s leading sailmakers. It has been designed to help sail manufactures streamline their sail designs by moving the batten tensioning hardware to the luff of the mainsail, up by the mast where the wind is already turbulent. This allows the sailmaker to reduce drag and improve the aerodynamics of the trailing edge of the sail.

The new batten adjuster from Allen will take a 10mm wide batten and has an adjustment range of 10mm with calibration marks to help gather regular sail settings. It can be easily fixed to a sail using the four nuts and bolts provided, and once attached gives a low-profile streamline finish.  

Made from glass-filled nylon and weighing only 33 grams the A.951-10 is a simple yet effective performance-enhancing product for any sailmaker. Check out the video below to see a hands-on video or get in touch with the Allen sales team for more information –
