Tanya

Tanya is the owner and captain of (in her vaunted opinion) the most beautiful convertible vessel traversing the Sea of a Thousand Currents and beyond. Her ship, the Tuna, appears to be a simple catboat with an ironwood hull and brass trimmings, flanked on either side by clumsy-looking floats. But Tuna isn't quite what she appears to be - the single straight mast is collapsible and easily stowed along with the sail. The glass canopy is raised and fastened, and finally the hollow floats opened and allowed to fill with water.

In her submersible form, the Tuna can't propel herself, but that's where the two Undertide crewmembers come in. Though she can't carry as much cargo as a big surface ship, or maneuver as gracefully as a dedicated sub, her ability to avoid abovewater traffic and weather while still navigating shallow shores and places without a dedicated dock means
