Bardzo dziwny i szalony projekt francuskich tratw mających najechać Anglię w okresie 1798-1801. Okręt na rycinie miał pomieścić 50 000 żołnierzy, 500 dział, a wiatraki (miały napędzać 4 turbiny) miały mieć wysokość 167 metrów!
"The first apparatus of war was a monumental thing, and was displayed for the world in this engraving, printed ca. 1798-1801. An exact representation of a raft, and its apparatus, as invented by the French for their proposed invasion of England, printed in London by J. Atkin, portrayed the monster: 2500' x 1800', with a enormous stone fortification that seems to have been about 500x500', the thing was powered by four water turbines driven by 550'-tall windmills, it was supposed to be capable of supporting 500 36- and 48-pounder canon, plus 50,000 troops. It looks like it was built for calm water."
