Seth's Boats is a shop located at the other side of left Taiga wall in the Ocean. It is difficult to get there and will require players to have enough money and a way to get back! This shop is selling Basic boat, Large boat, and Boat trailer. NPC in this shop is called Soth, and he proves to be Seth's Son.
Unfortunately, Defaultio has explicitly stated that this is very unlikely to ever exist. His reasoning suggests that the ferry is the only real need as there are no new planned features for the Bay as well as the surrounding Ocean. In regards to Palm Wood, it would be a great idea however, Defaultio has again stated that Palm Wood is intentionally made for decoration and that it is not meant to be harvested. While countless players have suggested a boat shop, it seems this feature may stay in the books.
