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 recently purchased the Sprint 15 Trampoline Cover from Sailing Chandlery, and I couldn't be happier with my choice. The cover is made from high-quality PVC material that feels durable and built to last, even in harsh weather conditions.
The fit on my Sprint 15 is absolutely perfect—it's snug and secure, ensuring that the trampoline stays protected from rain, sun, and dirt. The attention to detail, like reinforced edges and reliable fastenings, really sets this cover apart.
It’s clear that a lot of thought went into the design, making it both functional and easy to use. The vibrant blue color adds a nice touch and is easy to spot in the boat park.
Shipping was fast, and the customer service from Sailing Chandlery was top-notch. They kept me updated throughout the process and ensured a smooth transaction.
If you're looking for a reliable cover for your Sprint 15, I highly recommend this product. It's a fantastic investment to keep your boat in great shape!
The Topper rope pack arrived shortly after I ordered it. Very good service from Sailing Chandlery. I will fit it when I get home.
The sail numbers were simple to attach
Great value for money and swiftly delivered as always by Sailing Chandlery.
Very good sunglasses, I’ve just had eye surgery and was struggling with peripheral light sensitivity, these are great for that and will be terrific next season sailing.
Great to see these available again, much better quality and sensitivity than the alternatives
We have just purchased the Mersea twin Laser box trailer. Ordering the trailer, and adding the lid afterwards, was easy and straightforward with accurate lead times for its delivery. We paid for delivery to the South Coast and the trailer arrived bang on time along with other items we ordered. Fantastic customer service all round!
The trailer had its first trip this weekend, a 3hr drive on a mixture of town, country and motorway roads and it was a dream to tow - no noise save the odd rattle across potholes, easy to see in the car mirrors and very easy to connect and pull. It's also easy to manoeuvre two by just two people.
Our junior sailor was delighted by capacious box section with two access points and he was able to stow all of his kit to travel and then all covers, bags and kit whilst on the water today.
We're very pleased with the trailer - thank you Sailing Chandlery!
Good quality splicing tool, sensible price and swiftly delivered. Thank you
