A "good" paddling speed is subjective and depends on factors like your fitness level, the water conditions, and the type of canoe or kayak you're using. However, the average speed for canoes is about 3 miles per hour (4.8 km/h), and for kayaks, it's about 3.5 miles per hour (5.6 km/h). A more experienced paddler may be able to maintain speeds above these averages.
