The 20mm blocks we have available are a selection of the most popular:

  • Allen 20mm Dynamic Block

20mm Dynamic Blocks

Allen 20mm dynamic blocks are made from a mixture of polymers with high strength 316 stainless steel. The ball bearings inside are also made from stainless steel.

20mm Tii Blocks

Lightweight blocks which you can attached to your boat using the soft shackle that comes with the block. These blocks are reinforced with stainless steel in the right areas.

20mm High Load Block

Upgraded from the standard dynamic block with a stainless steel sheave for the rope to run around. This adds extra strength and doubles the working load of the pulley to an amazing 250kgs.

My favourite rope for splicing

Great rescue knife

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...

Zhik INS200

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

Useful little clips

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.
