You sure? 100 ships a day means 14 minutes per ship, and a lock cycle takes 10-20 minutes, so that's awfully suggestive to me. OTOH, I'm not sure of the relative difficulty and expense of adding height to a tunnel vs creating and operating a lock - I'd assume at some length it makes more sense to use a lock, since tunnel cost scales with length and lock cost doesn't.
- avar 10y agoI don't know why the limit is 100 per day, I'm just going by the article & the pictures in it which very clearly show a tunnel open to the ocean with no lock system. The photos also show a mountain going straight into the ocean, which means raising the ship with a lock wouldn't save you any money, since you'd need an unbroken sequence of locks going all the way to the top of the mountain.
