I apologize, but there seems to be an error in the prompt. The location given for the Mississippi River - River of the Lakes Landing (latitude: 42.89381409, longitude: -91.09709167) is actually in Iowa, not Missouri. Additionally, this location does not correspond to any known boat ramp or landing.

However, to answer the questions posed in the prompt:

1. Without information on the actual Mississippi River - River of the Lakes Landing, it is impossible to determine what kind of boat ramp it is.
2. The width of the boat ramp would also be impossible to determine without more information.
3. The Mississippi River - River of the Lakes Landing, if it exists, would service the Mississippi River.
4. The types of craft permitted on the water would depend on the specific regulations for that area, which vary by state and local jurisdiction.

Overall, it is important to have accurate and up-to-date information before using a boat ramp or launching a watercraft.
