Is spool shackle legal on Cunningham

Hi - I'd like to avoid having to re-tie the spectra that passes through the cunningham eye every time - can i keep a loop tied in one end and pass it through the sail and secure to the block with a shackle? Also, would a Spool Shackle be legal?

Thanks!
 
Rule 3 a vi Says :- When an “Optional” block, or shock cord is
attached to a fitting, line, mast, boom or the sail,
it may be attached either with or without a shackle,
clips, balls, hooks and/or a tie line.

So I would say yes. :)

Thanks Clive - this looks like a simple solution -

How about a couple of sister clips/brummel hooks?

Hi Zoophyte,

Check the break load of your clips. If you can pull with say 30Kgf then the load in the sister clip would be 5 times 30Kg which is 150Kgf. The break load of a Ronstan RF536 Sister clip is 70 Kg - not enough! You may be using a different clip though.

HJB, where did you get the spool shackle at I was looking I really like that
idea. Thanks in advance. MB

Good point Clive. I sail in a location that is generally light winds so not a great deal of force on the cunningham. Though maybe I should change to an RF89 just in case.....
