The Laser has had many different configurations during its life, in recent years alongside the 8 to 1 downhaul system we have also seen more people switching out their 57mm ratchet block for a 40mm ratchet block.
The main reason is the thickness of the main sheet. Most Lasers have had in the past 8mm main sheets. The 8mm rope sat inside the sheave of a 57mm block and gives more friction therefore more grip. But in recent years around the boat park, you may have seen people using 6mm main sheet rope.
6mm lines like Kingfisher Evolution Sheet and Marlow Marstron are lighter and smaller creating less friction through your blocks, making your sailing easier. Therefore having more control over the main sheet in lighter winds and the sheet going out easier and quicker when gybing and starting the downwind leg.
The 57mm block is designed to work with lines up to 10mm and by having a 6mm line running through the block it will work fine but the block is not working at its peak performance.
The 40mm can also take up to 10mm rope but being narrower and shallower the sheave works very effectively with 6mm and 7mm ropes.
Another big advantage to having the 40mm ratchet block is, on a winder day when you have all your control lines pulled hard on and excess rope in the boats cockpit you are less likely to have your controls getting caught and tangled in the larger opening of the 57mm block.
Here are the links to the two blocks for you to compare. Which do you use?

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.
