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.

Worn these for a few races now and they have been excellent. Really high performing. They are grippy and super supportive even without using the zhik toe straps. I’ve raved about them so much that my crew and colleagues at the club have now also bought the same ones
Ordered this when my son's training sail got rippd in action. Pleased to find it here 20% cheaper than anywhere else and as always delivered correctly and in great time. Thankyou
The bag is well made and large enough for halyards as well as other items. I have used the 3M fixings but these are not really adequate and so the bags will need to be screwed in place.
I would buy again.
Delivery was on time. The O rings fitted the hatches on my topper topaz. No issues excellent service
I ordered the hiking pads for my son who was very pleased with them. The order was delivered within a few days. I’ve ordered items before from sailing chandlery and have not been disappointed with the service I received. Thank you
Loads of space in this bag for all of my kit, extra pockets are very helpful and the compartment inside keeps my dry and wet kit apart. Would recommend.
Not actually for a Topper but for a sailing canoe I have built. Pleased with the quality, delivered promptly, just the job thank you!
I’m using this with the Clamcleat CL211 and they pair perfectly. Strong and with the stiffness that I was looking for. Really pleased with the purchase and excellent quick service.
These work fantastically. Used with 6mm rope they grip instantly. Easy to adjust in small amounts and lock in with no effort at all. I was concerned that when the pressure comes off that the rope would release, but this isn’t the case at all. Really pleased with the purchase and rapid delivery.
Just what we needed, bought a second hand Topper, needed new ropes, sorted..Fitting instructions could be clearer for novices.
Very speedy delivery, and the special short length is just what I ordered. Ordering couldn’t have been simpler. Excellent service.
Harken block
Bought when I changed the wheels - arrived well wrapped with the wheels and on time. Easy to fit quality product. Good service
Easy to fit and seem to be robust as a replacement for my Trolley wheels. Arrived as promised very well wrapped. Worth checking if you need new washers and clips to add to your order.
Though not cheap this control line swivel block is just the job. Well worth the money imho.
Save up to 40%on your next order.
