So did you land on something in the upper left corner of photo? It's looks cracked pretty bad there?
Is that a notch cut on the upper right @ tail area ? What's that for ? Did delamination start there as well after you cut it ?
The plate looks like it's got some delamination at the front, did you cut the plate to fit in that area ?
The hole you cut for pump clearance, opened the top layer for delamination, do you have delamination starting at that hole ?
You may ask Steve to build one specificly for you and your situation, you might step up to full carbon if he thinks it will help and have him do all the trimming and hole cutting for pump clearance while he's making it so the top layer stays sealed. Send him that plate so he know where to clearance.
How is it this damage keeps occuring ?
I remeber reading you ride pretty hard in shallow water.
Contact Steve directly and discuss the problems youve Been having and how it keeps occuring and if he has a recommendation as far as a custom plate specificly for your situation
