Kicker load on an Ent

I'm getting older but I do have a pretty good idea how strong I am (a couple of different jobs and hobbies over the years). 60kg I can lift and pull on a line in a favourable position. I could not pull that much from the side deck but we have to take into account the max loads when speccing rigging. Good quality snap shackles will have a SF of 3 but cheaper Chinese stuff likely no more than SF = 2. The shock loads possible on a kicker are likely to be at least 2 x static load so a strong crew setting up the kicker while leaving the beach and a strong wind gybe will probably exceed the breaking load of a 1000 kg rated shackle. 99 times out of 100 the l tonne shackle will be fine, the OP wanted to know what to use for maximum confidence. 

It shouldn't be too difficult to have a coarse and fine adjustment with a cascade kicker, take up the slack with the coarse and use the fine for power?

Originally posted by Granite I think that 1000kg will be more than enough. Sure there is a lot of purchase, but do you think you could feasibly lift 60kg, equivalent to a small adult with one hand using 4mm control line? Also think about the strength of other components in the system. Look at the final line strength, or final block type they will give you a good steer for strength of the system.

The weakest point in an older Ent kicker system is probably the lower fixing. Not sure how your's is fixed but mine were both screwed into the hog (early wooden boats, I can't remember but I imagine the kicker was no more than 4:1 TBH).
