I'd pay money to be a passenger on the maiden voyage. They should definitely include a few passenger cabins, as many freighters have. I have never been on a cruise - has zero appeal to me, but this would be awesome. I'd like to see more detail about this project, though. As others have commented, pure wind power is not going to be commercially feasible. There's too much variation in weather to work within current logistics demands. They do anticipate that it will take 12 days to cross the Atlantic, compared to 8 days for fossil fuel vessels. Is that to have enough slack in the schedule to sit idle for the port entry if the winds are good and they arrive early? But, I hope it's a success.
