Just talked to a rigger here in
Panama that has a multhull himself , retired now (72 years old) but with 40+ years of experience
When i told him about the tension his face went pale exclaiming ‘that is way too high for a self supporting mast/rig !!’
According to him the cap shrouds and lowers should be between 5 and 10% of breaking strenght , ‘go sailing and the lee should be loose , not slack’ and ‘with that much pressure you are going to bend the
boat , its not a mono that needs its
mast cranked down to the
keel, these are self supported rigs where the shrouds hold up the
mast , nothing more , amd certainly not pulls it down onto the
deck , put enormous pressure on the mast step or pull the hulls toward the mast’
I guess that 3800kgs (not Lbs !) and 2600kgs (not Lbs!) is too high
