In November the Sailing Chandlery team went down to Harken to improve our knowledge of the product range to support our customers with the purchasing of new Harken products.
Here are a few things we thought would be useful to tell you.
Harken use a range of different bearings for different applications around your boat from plain sleeve bearings to caged roller bearings made from Titanium to Torlon.
Roller bearings are great for use on applications where the load is high and static. An example of this would be Boom Vangs, Halyard blocks and Cascade systems.
The Harken Element block is one of the best plain bearing blocks on the market.
In the Harken range, roller bearings are found in winches and the biggest and strongest yachting blocks. The cages hold the bearings to a tighter tolerance than un-caged bearings stopping them from moving around and hitting each other when under load or rolling.
Black Magic, V Blocks and Winches all use roller bearings to work under and withstand the load that big boats have.
Ball bearings are by far the most commonly used bearing they can be found in anything from cleats, swivel bases, travellers, 16mm air blocks and mega yacht blocks. There are a few different types of materials for different ball bearing applications:
You would find Torlon Balls in traveller and genoa systems to work under substantial loads for longer-term use.
You would find Delrin balls in the Harken Micro blocks that are not under great load but are adjusted regularly whilst under load on small dinghies.
The Carbo blocks range from 29mm to 75mm. They can be ordered in a range of different specifications from cheek to triple block with a cleat and floppy spinnaker halyard blocks.
Carbo's reinforced glass fibre nylon is extremely durable and eliminates the need for stainless steel side plates. This all comes together to make the Carbo blocks 30% lighter and 60% stronger than the classic blocks.
The Classic range has been with Harken from the start. Therefore they come in at a lower price compared to the Carbo range as they are an evolution from the classic. One key difference between them is the bearing race, having the balls on a flat race causes a small contact patch whereas the shaped race of the carbo allows for more strength and friction, increasing the working load substantially.
The Fly blocks are a relatively new design from Harken. The soft attach blocks are slowly working their way into more boats and people are seeing its advantage. For example, the 18mm and 29mm Fly / T2 blocks are now the blocks every Laser sailor is fitting to their boat as they are stronger than the air blocks they were using previously. Mainly due to the shaped stainless steel bearing race and the use of stainless steel ball-bearings to cope with the load of the 8 to 1 downhaul systems on the boats.

Harken UK is a distributor for many of your other favourite sailing brands:
Harken works with these smaller brands to help our customers and us get these great products quickly and regularly.
Harken UK supports these brands to help them grow and get new products out for people to see.
Whilst spending the day with Harken you can see the lengths they go to create great products. For example, the Harken Marine Grip isn't like any ordinary grip that ruins sailing clothing at the expense of grip.
Marine Grip can come in 1 or 2-inch widths sold by the meter it's also available in different shapes and sizes like hexagons.
The marine grip was originally designed by surfers to replace surf wax. It's a thin design whilst remaining non-abrasive and grippy. The thin design also means you are less likely to catch the edge of the grip when moving around your boat and less likely to cause it to lift and come off meaning your grip will last longer on your boat. Different colours and shapes mean the design of the grip you can create on your boats are endless.

I have the 270 boots 2020, But these 170 boots are great, much easier to get on and off and very grippy and comfortable
Great range of products, very efficient service, item arrived well packed and on time
Really strong, does what it needs to!
Great product, does the job for a good price
Perfect product at good price and fast delivery. Thank you.
Best spring/summer hiking wetsuit.
As per usual the Sailing Chandlery team got these to me in a flash! Amazing service!!!
I have previously used the Superwarm version of this hiker and it was brilliant!
I purchased these as I get far too hot in my winter hikers during the sweaty summer months!
Only used once so far, but were warm enough in 15 degrees C and worked exactly as expected!
Good size handle, comfortable grip. I find I have to go down a size in needle than that advised for the rope I’m splicing.
Fantastic service and reasonable prices
Excellent service product delivered very quickly and exactly the item I required.
These were fine. But what was an issue was the number of emails I received after.
This is my most used item in my sailing bag. Keeps me warm on colder days underneath layers and I also wear it on top in the summer. The fleece lining inside is very comfortable.
These are brilliant socks. I tuck them inside my Superwarm wetsuit and because the seems are sealed it stops any water getting to my feet.
Small and springy - exactly what I needed !
But usual great service from Sailing Chandlery !!
