How deep can the submarine dive?
The Seattle 1000 is designed to dive to 305 meters, or 1000 feet. This is an optimum compromise that allows exploration at significant depth but also allows us to have very large viewports for exceptional visibility. If necessary, a small deep submersible could be carried “piggy back” by the Seattle, allowing a small group of 2-3 people to board the deep submersible through a transfer lock and dive to depths of up to 3000 meters or more.
