The Stanowar is a old, worn-out, ragged, hole-filled fishing boat owned by Stan Pines, originating from Gravity Falls. The boat was named after the Stan o' war boat found at Glass Shard Beach, New Jersey.
Role in the series
The boat first appears in "The Legend of the Gobblewonker" where it was brought by Stan to Lake Gravity Falls for a fishing trip with Dipper and Mabel. At first, the twins ask Stan if they can use it in their hunt for the Gobblewonker, but they then decide to ditch Stan and search with Soos on his boat, the S.S. Cool Dude. Stan goes about the day in solitude, annoying many other fishers.
After Dipper, Mabel, and Soos learn the alleged monster was just Old Man McGucket in a robot, they ask Stan if they can come aboard the Stanowar to make up for ditching him, since their ship has been destroyed. Stan excitedly lets them on, and the group spends the rest of the day enjoying themselves on the boat ride.
In "A Tale of Two Stans," it is revealed that the Stanowar is actually named after a boat wreck Stan and his brother Ford found on Glass Shard Beach, New Jersey during their childhood. The two decided to reconstruct it so that they could sail around the world together. This dream never came to pass however after the twins became estranged.
