Yak transport carts?

[Squawminnow]

I am finally getting into kayak fishing after drooling over them for years now. I plan on waterfowl hunting out of it too. I have been searching for a good transport cart to either build or purchase. I have read a few posts about the standard kind that has two posts that extend up through the scupper holes.
Some people have said those carts crack the scupper holes and ruin the yak. All of theses were hearsay though, no one said it happened directly to them. Any advice would be helpful.
