What must be carried onboard a pleasure craft at ALL times?

On a pleasure craft, at all times, you must carry a properly fitting life jacket or personal flotation device (PFD) for each person on board. Additionally, you should have a sound signaling device, such as a whistle or horn, and appropriate navigation lights if operating after dark. Depending on the size of the vessel, other safety equipment like fire extinguishers, a first aid kit, and visual distress signals may also be required. Always check local regulations for specific requirements.
