A grand covered berth with carved yew posts, a teal roof and warm lanterns. Its 5 by 4 water footprint includes a 3 by 3 open boat bay. Start the rear centre beside a walkable bank or dock, with the whole footprint inside one owned or approved plot. Turn the preview before building. Boats keep their normal ownership and speed. Dismantling any deck takes down the whole boathouse.
On water inside your own or an approved plot, choose Build a plank bridge here. Start at a walkable bank and extend one tile at a time. Use Build another for the next section. Boats moor at its edge.
