Ra doesn't do too well, since he doesn't have the Leviathan or the Turtle. Heroic/Mythic units, respectively. If I can avoid the water I will. Such as Mediteranian(I think thats how you spell it), I don't put anything near the water.)
Scout where they have their Dock, of course try to destroy it, but they will have their Transport out a little bit before they get units in it. Destroy it ASAP, always scout for more docks. Go heavy on wood and gold.
You might want to choose the God Path:
Bast - Hathor - ?
Bast for wood; Adze of Wepwawet.
Hathor for Sun Dried Mud Brick, Petsuchos and Roc; make Petsuchos and put them near the water's edge, they take out boats extremely fast. Rocs help as transports. They can drop off units deep inland., and use the Sun Dried Mud Brick to spam docks, towers, barracks, etc.
I try to get 3 docks together, that way I can make 3 boats at once there to defend them.
Put up obelisks all along the water. In mythic use Lighthouses for a great line of sight off of the shore.
As you know it's great to control the water on water maps, but don't forgot to mass a land army in the process. You never know if the enemy will use any special transport techniques(Underworld, Shifting Sands, etc.)
I'll add anything if I can think of it
