Oddly, the boats inside the Lifeboat Dock in Kingsparrow Fort also have "Amaranth" on their sides and carry welcome mats. This may have been an oversight on the developer's part or may mean Samuel's boat and the others are of the same brand.
Barnacles occasionally grow on these boats. Samuel can be heard making references to cleaning off the barnacles between missions, though is never seen doing this.
