Captain Davidson's ship, registration number 73620, was a sailing vessel owned by Captain Davidson that was docked at Rampone's Dockside Shipping in the Wayside Docks at the time Garrett visited. While infiltrating the ship, Garrett discovered an unidentified body in the hold.
The unidentified body may or may not be an undead, as when you pick it up it registers as a corpse, but when attacked it groans.
The vessel appears to still be in use despite being completely walled in by towering rocks (this is likely a sign of low tide, at certain times of day at higher tide passage would allowed between the rocks).
For unknown reasons, the foremast is completely backwards, the mainmast has no ratlines (rope ladders), and the ship is carrying live spiders.
