[Public-list] inverter - sheet splicing Genoa leads

Wed Oct 11 11:08:20 PDT 2006

No our sheets are standard Bridgeline ropes double braid. It is I believe a 
variation on the 'mobius brummel' except the tail lengths are identical. It 
is a small neat splice and hasn't failed in 10 years of sailing.
