	1. Catamaran rig tuning - BIG tension in the diamonds ~~stabilizes the rig~~ <br>		# Catamaran rig tuning - BIG tension in the diamonds induces prebend creating a stiff/stable mast section <br>
	2. Shrouds and headstay ~~are minimally~~ tensioned and ~~reduce shock loading - excessive tension~~ can ~~damage a catamaran bending it in half<br>~~		# Shrouds and headstay have much less tension. Over tensioned shrouds compresses the mast into its base structure and lifts the hulls. That can change hull shape affecting things like doors opening/closing or compressing the mast step structure.<br>
	3. ~~Too much tension is the common mistake with catamaran rig tuning~~<br>		# Reaching and upwind, very roughly around 15 knots of wind and higher, the leeward shroud will become loose/floppy due to normal shroud wire stretch. This is not a rig tune problem.<br>
	~~4. When on a close-hauled in~~ 15+ knots of wind, the leeward shroud ~~should get~~ loose<br>
