Time for action — making the other seat
The first seat was pretty straightforward. The second seat is in the bow, and to fit in it, the front edge of the seat is a little narrower than the back edge. So, you'll copy the first seat, and modify the copy.
Change to the Top view. Zoom out till you can see the entire boat.
Select the Viewport Shading menu from the 3D View header, and set the shading to Wireframe again.
Change to Edit Mode.
Select all of the vertices.
Press Shift+D to duplicate them. Move the mouse down, and press theMMB to lock the motion to that direction. Move the new vertices to the front section of the boat.
Look at how much of a gap you see between the ends of the center seat and the hull. You will want to give the new seat about the same gap between the ends of the seat and the hull. Since the bow is angled first, you will scale the front seat in the X direction, so that the rear edge of the front seat is the proper width. Then, you will scale the front edge of the front seat...
