Paddle sports such as canoeing, kayaking, and stand-up-paddleboarding (SUP) have their own risks and in most regions, laws apply for their use.
Safety equipment is often legally required and simply good sense. A lifejacket for each occupant is an important step and much better yet, wear that life jacket.
Think about the water temperatures, currents, and weather conditions you might encounter, the water temperatures you might fall into, how you will call for help in a time of need or crisis, and how you will resolve some of the anticipated risks.
Consider taking courses that will help you and your loved ones safely enjoy those water sports.
