This Hobie link will show how to change the rudder lines and
adjust the rudder for centering.
https://media.hobie.com/digital_assets/ ... Uo8dIw.pdfSince the rudder lines will tighten up on a warm/hot day, it's best to adjust the line tension on a warm day. It won't leave 2" of slack on a cooler day.
Maybe the previous owner replaced the rudder lines and never performed the final tension adjustment.
Since the earlier Hobie Mirage kayaks did not have a "Boa" to adjust the rudder line tension as the hull expands and contracts, you need to live with the fact the rudder will have a small amount of slop.
