Some photos of my friends Slingshot Glide that he snapped, then repaired, then snapped again. No fault of the board, he rode this thing HARD for 2 years and he's a 200 lb. guy. He cracked it the first time trying to railslide a submerged boat.
I found it really interesting to disect the construction and see what tricks they hide under the topsheet. Some good info to use as a baseline in building your own board.
Looks like they used a good amount of filler as well to get a clean finish on the dcell core.
Interesting construction, dcell core with a really thin (~1/32") wood reinforcement under the pads offset slighty towards the heelside edge:

Closeup to show how narrow the ABS rails actually are ~3/16" (4.75mm)

Pulled back shot showing the width of the wood reinforcement, it's about 10.5" wide
You may enjoy this video I made which details the 2009 SS board construction. Albeit after some rum...this was my first time seeing the inside of a current board. This year's boards are really impressive. You can see the ABS side rail coming in about an inch on the sides and it comes in about 5 inches or so on the tips of the SX. It really has a lot of protection so you don't blow out that edge. Vertically laminated aspen wood on the edges, some divinycell, and then a very wide aspen wood core in the center. Solid.
I don't think they use all that filler any more that you saw on the old Glide. All the cross sections I saw of this went directly to top sheet after the Dcell or aspen core. The colored top sheet had some other clear sheet on top of it for protection. That probably smooths things out as well. But I'm not a board builder so really don't know what I'm talking about...
