import searoute as sr

origin = [121.545763, 31.254191]
destination = [130.392684, 33.628909]

route = sr.searoute(
    origin,
    destination,
    units="naut",
    append_orig_dest=True,
    include_ports=False,
    restrictions=['northwest'],
    speed_knot=1
)
print(route)

Expected Result
A maritime route that stays at sea.

Did you try with append_orig_dest = False?

You should get something like this:

Also the Maritime network doesn't have a perfect resolution, otherwise the network would be too dense. The idea of this package is to offer a possibility to compute distances and paths relatively fast.

However there is a possibility to improve the geojson which consists of the Marnet.
Feel free to improve that file and share it directly here, I can include in next releases.
