Ideas: water community structures

[Mukti]

I noticed there are very few water structures (including plug-ins) that have actual use. So, I am recommending structures that can be built on water.

House boat - residence t1, 4 people, only requires water: 1x1
Motor house boat - residence t2, 10 people, requires water & electricity: 1x2
Yacht - residence t3, 100 people including doctor, requires water, electricity, park influence: 2x5

Generator platform : generates 200 electricity: 2x2
Nuclear carrier: generates 50k electricity, gives radiation, requires water: 4x8
Distillation platform : uses electricity to remove salt from water and generates 200 water: 2x2
Distillation tanker: generates 50k water, requires electricity: 4x8
School boat : Primary/Elementary education 2x2
Cruising School: Primary/Elementary & Secondary/Higher education on a Cruiser, requires water & electricity: 2x5

Police Speed boat: gives police influence, requires water & electricity: 1x2
Police destroyer: battleship that gives police influence, requires water & electricity: 2x5
Salt water speed boat: spray salt water and gives fire department influence, require only electricity: 1x2
Salt water tanker: spray salt water and gives fire department influence, require only electricity: 2x5
Clinic speed boat: gives health influence, require water & electricity: 1x2
Cruising Hospital: Hospital on a cruiser, requires water & electricity: 2x5

Floating dock: connection point for transit lines, employs 10 people, gives transportation influence, requires water & electricity: 2x2
Transit lines: connects 2 Marinas/docks, acts like bus route and give transportation influence.

Floating port: connection point for shipping lines, employs 50 people, generates pollution, requires water & electricity : 8x8
Shipping lines: connects 2 ports, and employs 100 people per shipping line connection.
