I would like to see fishing boats be able to be built on any water tile like mines can and have them provide bonuses similar to the way farms do however a bit less.

Take a look at Shureshots Svartalfar mod for FFH. She did something like this.

I myself made lighthouses available for every city in my empire, means even to non-coastal ones. Does a good job either. Makes many possible settle positions much more viable.

There's something similar in the RoM mod too.

After I took a look at surefire's code it was easy to impliment in my game thanx guy.

I would still like to see this be a standard for FFH though

I'd prefer sea tiles to be improved in other ways. I'd hate if I would have to use workers at sea as well.

I'd like to see the Colossus Wonder brought back from vanilla, not necessarily with the same name and graphics, but the effects of it. +1 Commerce on every water tile in the city radius. And then I'd like to see another wonder that gives +1 Hammer on every water tile in the city radius.

And then maybe some other buildings to improve on the water more in some ways.

But I'd hate to have to use workers at sea as well. The way fishing boats work now is perfect.

Ack! Please no more micro-management! This idea would completely kill gameplay on Large or Huge maps.

Even having to build city-specific buildings would be a pain in the ass once you get 10+ coastal cities, but its a hell of a lot better than having sea workers. I'd rather see a semi-expensive techs branching further off the sea-faring line that would give slight bonuses to coastal and ocean tiles...or maybe just coastal tiles. Most civs could ignore these techs without suffering too much, while others (ie, Lanun) would probably implement these techs into their overall strategy.

Isn't there one of those in BtS? FfH may well co-opt it.

no that adds production to rivers

The Dutch-Specific building adds one production in each ocean/coast square.

And a Portuguese building adds commerce for water tiles.
