The boat is constructed to an Australian design, with a solid hull, designed to ride out big southern ocean swells.
The ocean of water buoys or floats the ship, and the ocean of air, or part of it in motion, swells the sails which propel the ship. The moving air, which strikes the sails directly, strikes.
The nave is thus covered completely by a domical canopy, which, in its ascent, swells larger and larger, mounts higher and higher, as though a miniature heaven rose overhead.
With water it swells by absorption, and with even fifty times its weight of that liquid forms a thick mucilage.
