Reliable 24/7 energy.
Intriguing idea so I did a quick calculation: for a 500,000 tons boat with two 10m tides per day, I get about 1.15MW of available power. You can get that with a wind turbine. And having a mechanism capable of holding a massive boat in place in any weather and converting its movement to power doesnt sound cheap or easy.
Though there are a lot of freaky designs being tried to get energy from tides or waves so maybe something like that already exists.
