You can legally operate your vessel at greater than no-wake speed in open waters, away from defined no-wake zones, and as long as you are following the rules and regulations set forth by the local authority or waterway management. It's important to always be aware of your surroundings, other vessels, and wildlife when operating at higher speeds.
Requirements for vessel registration vary from state to state. In Texas, you must have a Texas Certificate of Number (registration card) and validation decals to operate your vessel legally on public waters. The only exceptions are:A sailboat under 14 feet in lengthNon-motorized vessels such as canoes, kayaks, rowboats, and rubber raftsVessels registered in other states and using Texas waters for 90 consecutive days or less
