A highly technical custom yacht is currently under construction by Delta Marine called Project 'Zembra'. It is a 45-meter being built by an experienced owner. It will carry the superyacht 3 model submarine from Uboat Worx on the transom and also is having a custom 50-foot aluminium catamaran from JR Marine to serve as a chase boat and will be handling the operations of the submarine.
