Basic gear includes the things you cannot go on canoeing day trips without: one paddle per person, extra paddle, one personal flotation device (PFD) per person, extra PFD and canoe seat. Bring along items you think may also be necessary for your specific trip such as: knee pads, yoke, dry bags for your gear, spray covers, weather radio, signaling devices (mirror, whistle, flares), emergency floating throw line, bailer or bilge pump and sponges.
Bring safety gear in case of emergency--many unpredictable things can happen in the wild. Also, pack core items--these are other useful items. Safety items include: navigation tools (maps, charts, compass and GPS), first aid kit, knife or multi-tool, two-way radios (if going with a group), matches or lighter and flashlight. Core items include: cell phone, watch, sunglasses, sunscreen, lip balm, water bottles, water treatment method and food. Pack items in a water-resistant bag and also bring extra batteries for electronics.
What you wear is a matter of preference, but some clothing options to consider are: dry suit or top, swimsuit, paddling gloves, neoprene footwear or sandals, helmet and hat or visor. Consider moisture-wicking clothing to stay dry and comfortable. It is also a good idea to bring a waterproof, insulated jacket in case of rain or colder temperatures.
