I feel we've strayed a tad from the intent of the OP
"Post a synonym for (or metonym of) the previous posters word."
But I'll run with it.
People say a boat load of something, also a shed load so..

Out of interest, where did you feel the thread went off course? Reading back through it, it all makes sense to me!
Initially I was confused about Instigating to Launch but I guess if you drop the verb ending to Instigate, Launch would be a synonym. I can't figure the Launch to Boat though, as a synonym. To me that is more word association. Am I missing it?
A launch is a type of boat.... that's me being a boaty type though, I thought that might be the one you were wondering about!
