I am having trouble with your thread title "World crushing-Fast-under 30' tri". If there is no mistake and you want a "world crushing fast" boat then you need to look at foils, because today really fast means foils, anything else is slow.
If you wanted to write "World cruising -Fast-under 30' tri" you are fresh out of luck. Nothing under 30 is a world cruiser. You may do long passages, even crossing oceans, on such a boat by beeing hard core minimalistic, but you have to be a special breed of sailor for that.
However it is, crushing or cruising your chosen model has nothing to do with either. The Spark is a weekender with a go easy rig. A good boat for what it was designed to do, but it was not intended for cruising or to be crushing fast.
At a stated budget of 100 000USD I don't get the need to build. A F-82R fits the budget including any upgrades you may want.
I would see a need to build only if you wanted a crushing fast world cruiser under 30, in wich case the budget is to low.
