I'm sceptical about the practicality and economics of large airships, but I'd love to see small airship 'yachts'. Santos-Dumont's Dirigible No.6 [1] could 40km/h with a 12hp engine in 1901. It had a 630 m³ balloon (33m long x 6m diameter, total mass ~600 kg). With modern engines, materials, and modelling you could make a very comfortable and quite speedy 2-3 person yacht in that size. 1. https://en.wikipedia.org/wiki/Santos-Dumont_number_6 https://en.wikipedia.org/wiki/Santos-Dumont_number_6
