That was altogether much more information than I needed. I suppose I am grateful for the context. Nevertheless, we simply need to know what model of ship you intend to rig. Navigational software is not what we intend to create, and so a simple timed explosive detonation sequence will suffice for your needs. We will distribute this code amongst the software to be delivered to Madeira upon our agreement of a deal. I will seek a price estimate without the ship information, despite the dependence on it. That, or how much and of what explosives you intend to rig on the ship, is important information.
