Alternative Mayan UP suggestion: Double all yields for each core tile. 

Unless I find a workaround, that would be hard to implement. Currently the code tracks directly for every tile which city works it.
I could image +1 commerce per adjacent city. So your first ring already has +1 and if you build cities one tile apart you could get +2.
So, Polynesia is usually disabled if you're not playing it. Probably because it doesn't really do anything.
I figured out how to make it successful: Change the AI of its ships to Settler Sea.
It's less about their strength but instead that the current UP does not feel like a power at all, since everyone has different tech modifiers.I am playing Mayans for the default difficulty and first 2 UHVs are really doable with 40% discount. Many European Wonders are available to be built even. Current UP is not bad after all. It may not be very exciting or elegant but it does the trick, and Mayan UU provides all the excitement!

I don't think this UP will make any difference. It's like what, three removed rainforests? Also worse than the Congolese UP.It probably needs more constraints, like road + cottage improvement + core.
I think that is really overpowered, especially if you don't play for the UHV. It basically means free food on every land tile.
I do like the idea of sacrificing slaves to build the temple.
Can you actually copy paste the relevant code so we could see ow to do it? Do you have to change Default AI only?
<Class>UNITCLASS_GALLEY</Class>
<Type>UNIT_POLYNESIAN_WAKA</Type>
<Combat>UNITCOMBAT_NAVAL</Combat>
<Domain>DOMAIN_SEA</Domain>
<DefaultUnitAI>UNITAI_SETTLER_SEA</DefaultUnitAI>

I don't think the fact that Polynesia doesn't do a whole lot is the only, or even the main, reason why it's not in the game by default. Even if they spread throughout the Pacific, they're unlikely to have much of an impact on the rest of the world, and since they spawn so early they'll probably end up collapsing sometime in the Renaissance, leaving the Pacific riddled with a bunch of mostly useless Indy cities. They're cool to play as, but not very compelling as an opponent.
