You've used this example before, with me, and I don't see how it necessarily means fiberglass is a bad idea for our Spoon handle.
A golf club is all about impact. It just has a surface designed to withstand the impact--the angled face on the metal head, obviously. The shaft can flex and/or twist slightly at the moment of impact, then recover. It's not a problem because the head is much more dense than the shaft. By that time the ball has already been propelled downrange, but there still is bending and reformation.
Now, if you lose your temper and smack that damn oak tree that's always in the way with your 9-iron as hard as you can, and in your blind rage make contact with the handle, then yeah, your spendy carbon-fiber shaft will probably evaporate into flying threads (and woe betide the poor schlub standing in the path of the club head). But if you manage to hit the trunk dead-on with only the head, well, you'll put a nasty dent the bark. Feel better now, bruiser?
Anyway that's what I think you're picturing, since our "club" (the Spoon) isn't hitting the "tree" (horizontal 2-by-4 at the top of the frame) with the "head" (the bowl of the spoon). Bear in mind we've already got a few small mitigating factors to that impact--the frame is well padded at that point, and if the handle is positioned just right in the rope spring, the Spoon should hit the pad exactly at the bend, with the angle of the pad matching the angle of the bend, so that the heavy bowl of the spoon is supported & its tendency to flex downward is reduced. (The weird 90-degree spoon head is practically pointing in the direction it's being propelled already, in a ballistically inefficient and un-catapult-like manner, because it happens to be the way Spoonbridge and Cherry was sculpted.) So... all we should have to do is make sure the Spoon's handle is hardened at the point of impact.
A fiberglass boat has a sort of built-up "lip" around the gunwale, where it's likely to run into piers, the dock, other boats, etc. (Don't drink and sail, y'all.) It is possible to reinforce fiberglass against impact with more fiberglass. Of course, it's better if you use those rubber bumpers, 'cause that's what you bought them for, cap'n.
