The 57mm block from Harken comes in three formats, the carbo, the ratchet carbo and the newer Power3 ratchet blocks. The ratchet version of the 57mm Harken block come either with on/off switches or as an automatic ratchet.
Harken 57mm blocks are lightweight, strong and reliable with a fiber-reinforced composite construction meaning they have a great strength to weight ratio.
You can expect breaking loads of up to 2,270kgs.

My favourite rope for splicing
Solid folding lock knife, this is my third one (dropped the last and the first I had for over 6 years).
Looks like it will be good at cutting rope, I've only ever used it for cutting cheese...
we order some stainless beta pins, good price and very quick delivery.
Zhik described this range as medium waterproofness. Unsure what this means and whether I need a spare set of gear for stronger weather. Not convinced but it fits well and it’s a good make. Would be good to see a long term review
The Inglefield clip was invented by Lieutenant Edward Inglefield RN in the 1890s, it has been standard issue to British warships since 1895.
The idea was to make a reliable and fast way of assembling a hoist of signal flags, which they do very well.
I have had a long involvement with these clips, mostly for flags, but they have other uses, for example the West Lancashire Seabird One Design (a half rater) use the clips for their spinnaker halyard attachment to the sail, and I have seen a big version cut out of steel plate for a special job.
The standard clips are made from brass, these medium size nylon ones are clearly not as strong as brass, but they are good for small flags.
A further advantage is the avoidance of metallic stains on the bunting.
I don't think they would be strong enough for a big flag in windy conditions, but that isnt what i purchased them for.
