3 Harken air blocks - 22mm single sheaves

A quick release hook suitable for the clew

1.5 metres of 4mm rope

6 metres 4mm rope

25 cm of 3mm shock cord


This is a design  for a simple but upgraded classic outhaul without using deck fittings. If any more purchase is required then buying the XD deck fittings before anymore blocks is the better option.
