Hey Will, my buddy had a similar storage problem with his Necky Dolphin...A standard crate just wouldnt fit.
He built this out of a dishpan, some PVC pipe (heated and pushed on a wine bottle for the openings) and a piece of metal acrossed the part where he mounted the rod holders to add stability. With the crown yours has you may need to add something to shim up the side gaps before you strap it down.
This is the best pic I could find to blow up the "crate/pan".
Probably cost him less than $20.
Hope it helps. Good luck.
