[Public-list] inverter - sheet splicing Genoa leads

Wed Oct 11 10:48:51 PDT 2006

Very interesting - never knew it by that name...

We use it for our 12 strand dyneema core in sailng ship shrouds and stays.
Now there is a sight... 4" diameter shrouds, eight to a side to a mast...no
turnbuckles... 20" diameter deadeyes with 1" diameter lanyards...
