Hey, I see to be having an issue with adding parts onto the craft. I've constructed a small crane, using KAS and a hinge (from Infernal Robotics I think). It works fine normally, however when placed on the carrier it causes issues. The carrier loads in the ocean fine, but then when the "moving to water" text appears the carrier immediately starts rocking, it normally balances quickly but the crane pieces go crazy pulling away from the boat until they rip off, normally landing in the ocean or on the deck. It doesn't seem to be the rocking that destroys the crane, it works fine if the carrier has no crane.
