From the Iowa boating regs:
Quote:
Reckless Operation:
No vessel shall be operated within Iowa in a reckless or negligent manner. Examples of reckless or careless operation include:
Excessive speed in regulated or congested areas
Operating in a manner that may cause an accident
Operating in a swimming area with bathers present
Bow riding or riding on the gunwale or transom where no seating is provided
Operation of a personal watercraft which endangers life or property
Now, “reckless” is a hard charge to prove, but certainly:
Quote:
Speed Limits and Horsepower Limitations:
You are responsible for your wake. Do not exceed 5 mph within 100 feet of any boat going 5 mph or less.
When two boats are operating at over 5 mph they should stay at least 50 feet apart.
You should not exceed 10 mph unless vision is unobstructed more than 200 feet ahead.
On inland lakes and federal impoundments: Do not exceed 10 mph within 300 feet of shore (except in specially zoned areas).
Violation of any of those would constitute a provable offense. If it happens on Iowa waters, turn them in. Please refrain from taking up a beef with the bass fishermen of IDA. They may be the black sheep of our little web-community, but they’re ours nonetheless, and will be defended with rigor.
