Harken ratchet blocks start at a 40mm sheave size and run up to 75mm sheave size for use on a majority of dinghies and catamarans.
There are four types of Harken ratchet block:
All of these ratchet blocks come in slightly different forms.
The T2 soft attach ratchet blocks are popular because they are lightweight with the flexibility of being able to be lashed or spliced anywhere on the boat. The T2 only comes as a ratchamatic which is an automatic ratchet block. As soon as pressure it put onto the block from the attachment point the ratchet engages, when there is no pressure it releases and doesn't engage.
The carbo blocks are popular where the block isn't going to need to move, or where it will sit and happily do the job of making your sheeting easier. This is the standard block issued for a Laser mainsheet block for example, it sits in the middle of the deck with a spring underneath. Carbo blocks are attached using a shackle.
These are available with an on/off switch in the centre, or as an automatic ratchet which can be adjusted using the allen key provided with the block.
The power3 ratchets are the latest blocks from Harken.
Available as a carbo on/off, automatic carbo and T2 these blocks have two different sheave designs which are more aggressive and grip the rope to provide either 1.5x or 2x the grip you would get from a standard block.

I rang to request some advice on replacement parts for my dinghy and was very impressed with the excellent advice and efficient delivery of the required parts. Many thanks
Great product, safely packaged, delivered on time, at a competitive price. One more thing - the person on the end of the phone is an actual person, informative, helpful, knowledgeable and pleasant. What more could you ask for.
The sales team were quick responding to our questions, dispatched to us promptly, and the product is a perfect replacement for our old tiller which ended up at the bottom of a lake!
It was time for me to upgrade to a newer Ilca and it was recommended that I get a Devoti. The price was competitive and the service from Andrew and his team was fantastic. I received lots of communication and the boat was delivered to me within 2 weeks. It is really great that Sailing Chandlery take the time to set up the rigging so that you can get straight on the water. I am very pleased with my new boat and am loving sailing it. Thank you Sailing Chandlery!
Ordered a dyneema RSAero halyard on the Thursday. It arrived by mid day on the Friday and was used on the Saturday. Excellent product and service. Thank you
Cover arrived after three days and is well made and completely covers the boat boom up . The straps and clips all work fine. Good product.
My local chandlery were unable to supply a white inspection hatch and so it was amatter of looking online. Sailing Chandlery had the cover I needed in stock at a good price and delivery. I had never used them before but the service I received was excellent with the delivery on time and the hatch is now fitted.
I will definitely return, especially with the discounts on offer. Thank you Sailing Chandlery!
Always happy with my orders from Sailing Chandlery. They are quick to post and very helpful when I have had a question.
Jason delivered the boat on time at Hayling Island Sailing Club. The boat was new and all the spars were in perfect condition. Jason came to pick up the boat and return the deposit which I gave at the time of the delivery. Every interaction with Andrew and Jason were handled very professionally. I will recommend to any sailor Sailing Chandlery in the future. I really appreciated how easy it was to charter this boat. Thank you very much. Jacques Kerrest
Prompt delivery, with helpful updates and time slot spot on. Perfect new sail at a great price and the number fixing service is well worth it. It even won its first race! Thank you.
