Thru hull underwater camera position

[got cake]

I have 2 thru hull cameras to mount on a catamaran and am wondering if anyone has any experience to determine the best installation. The cameras have a 90 degree angle view.
I already have a number of underwater lights to the aft as well as inboard and outboard of both transoms so at least one should take advantage of the available lighting.
Questions are:

Should one of the cameras be in the bow? If so, is there merit in pointing it forward to provide an underwater view when picking your way through shallows? No lights up there but for day it might be fun to see where you're going? And the odd Dolphin might show up as well.

For the camera or cameras at the aft we are hoping for aquarium-like views of sea life. So, would you recommend facing the camera inboard, outboard or aft? And, should the view be horizontal or angled down such that the edge of the view remains below the surface?

The cameras themselves will be around 2 feet below the surface.

Thanks in advance.

I never cease to be amazed at the toys people mount to their toys. I'd prefer to have one mounted at the masthead (image stabilized) rather than the bow. Then again I'll never be making that decision.

I would like a video camera aimed at the stern, so I can see the transom while docking.

I like the idea of being able to see under the boat, but make sure there's no way for water to enter the boat if one of those things breaks, comes loose, gets smashed and creates an avenue for water to enter.

Most of us want fewer holes in the boat, but it looks like you want more. Good luck.

What we might get next season after it's perfected a little more, is one of those helicopter waterproof drones which can land and shoot underwater video from a gimbaled housing that's broadcast back to your ipad or iphone. Maybe you can save up for something like that? More multi purpose.

Currently, the price is $1600. The batteries only last for 19 minute without the camera attached, so presently, this doesn't fall into our comfort zone.
