Boats run the risk of getting a rope caught around the propeller. With outboard engines and most outdrives, this is not too much of a problem: you can lift the prop out of the water to clear it. With shaft drive transmission however, it is less simple because the propeller is under the hull and you may need to call in a diver. Canal boats, which tend to collect weed around the prop, frequently have the ideal solution built in – a weed hatch accessible from the inside of the boat.
