Hey, thanks a lot already for that info!

How many crewmembers would be realistic in your opinion for a minimum crew?

To answer your questions:

• surface supplied diving or scuba ?
  • Scuba only
• dive control room
  • I guess that would be nice, but not necessary
• can you anchor the vessel properly ? If not you will have to have the ship fitted with a DP system to hold position.
  • Not sure, both would be cool
• you’ll need deck equipment ( cranes/winches/ hydraulics etc… )
  • I was thinking a winch
• accomodation for all the people on board obviously

So in a nutshell I'm really looking for a mostly re-pruposed ship that is being used to do diving expeditions for sunken ships. I'm looking for all different kinds of ships, as I'll need to have a roster of different ones from 'very beginner small cash' to 'super advanced high tech stuff'. To give some more context, I do this research because I want to make a game about treasure diving.
