Nah... it most likely would have cracked sooner and possibly more significantly if it were kiln dried. I borrowed the following below from Matt Cremona... https://mattcremona.com/urban-logging/sawing/cutting-and-drying-cookies He talks about cookies but the stresses he talks about exist for whole logs and for beams that include the pith (pretty much all hand hewn ones). You need to dry them as slowly as possible to avoid cracks and then they will likely crack anyway.See! All that cracking in those beams. I bet that wouldn't have happened if they had used kiln dried wood.
Man what a beautiful floor. I'd kill to have a floor like that.
So now you may be wondering why do these things crack in the first place? Why is crack free drying take so much effort and even then they probably will still crack? Well the simple answer is they’re not designed to dry without splitting. It the tree’s structure and material properties that we are fighting. Looking at the face of the cookies, we can see two of the wood’s planes. The tangential plane follows the growth rings around the tree. This plane can be thought of as the length of the growth ring. The other plane is the radial plane which goes across the rings from the center of the tree (the pith) to the outside. This plane can be thought of as the thickness of the growth rings. The cookie self destructs due to the drying relationship between these two planes. As the wood dries it will shrink but the tangential and radial planes shrink by different amounts. The tangential plane will shrink more than the radial plane. The exact ratio varies by species but it’s generally around 2x. Due to this relationship as the wood dries and shrinks the growth rings will be put into tension as they try to shorten trying to compress every ring closer than it to the center. Stress builds until the wood splits. Also keep in mind that the further from the center a ring is, the greater it’s circumference and therefore the more it will shrink.
Anticipating an uproar I had a back up "ghost ship" that benefited from my stealth enhancements. Don't remember if it won overall or came in 2nd to my other son's boat...
