Schooner Shroud Tension

[bobsummers]

I have recently purchsed a LOD 31', LOA 42, skipjack gaff schooner. Currently the standing rigging is loose when at the dock. Loose meaning that I can shake the each shroud easily. When sailing the leeward rigging is amazingly loose. The bowsprit whisker chains are likewise as loose and undersail the tip of the bowsprit becomes severely deflected to leeward, the forestay with the jib set creates an arc to leeward. The yard were the survey was done said that if nothing has broken, leave it alone!!

Doesn't make since to me!!! Last thing I want to do is replace a bowsprit or spar. I would like to begin adjustments by getting rid of all the slack at dock on both the foremast (2 shrouds each side) and mainmast shrouds (3 shrouds each side), the 3 bowsprit chains and the forestay. She has running backstays for the foremast with deck levers. This seems like a logical step to me (I have only owned bermuda rigged boats before this one). Is there any risk to the rigging with this as a first step?
Thanks
