Jackstay Tension

We recommend that deck jackstays be installed in a manner that allows for a certain degree of elevation in the centre of the line before subjecting it to any substantial load. The extent of the lift should be in proportion to the total length of the jackstay and should account for the inherent stretch of the jackstay.

For webbing jackstays, it's essential to install them tightly to minimize slack when subjected to the load of body weight however not to overtighten as this equates to excessive stress to deck fittings and minimises the elasticity of the webbing.
