Transport Canada's Office of Boating Safety offers some boating safety suggestions for Canadian boaters this summer. They are of value to boaters in other regions.
Make sure the boat you use is in good working order. Be sure it is properly equipped. Using a Pre-Departure Checklist will ensure this happens.
Lifejackets - Each person onboard needs to be wearing a Canadian approved lifejacket that is in good condition, clean and fits well. Check the function of buckles, zippers and fasteners. An approved lifejacket will bear a tag or label in French and English showing certification by Transport Canada - Department of Fisheries and Oceans or the Canadian Coast Guard. Around 90% of the victims involved in water related fatalities were not wearing a lifejacket. Both swimmers and non-swimmers alike should wear a lifejacket.
Boating Gear - Depending on the size of your vessel, you will need at least this minimum level of equipment onboard:
Pleasure Craft Operator Card - Proof of Competency Cards are required if you were born after 1 April 1983 or operating a vessel less than 4 meters (13.2 feet) in length. All powerboat operators will need proof of competency by 15 September 2009.
