I'm a lake guy and love having the room to avoid other boaters by a wide margin. What would be proper when your on a river and you come across an anchored boat? There is NOT a posted no-wake zone involved. Do I need to slow, go no-wake speed, or just keep a safe distance regardless of my speed? The river I'm thinking of is the Illinois. Wide enough for two-way traffic to go 40, but anybodys wake will usually be hitting both shores. No incident or anything, just no river experience on my part. Don't want an incident or a ticket.
