HM Coastguard dealt with 578 incidents involving such craft, ranging from people falling in the water and fighting with strong winds and rip tides to rescuing canoeists with a lack of survival equipment.
Another key issue identified was that Coastguards are spending valuable time tracking down owners of abandoned or drifting canoes or kayaks.
On a number of occasions there have been large-scale missions involving coastguard rescue teams, lifeboats and search and rescue helicopters.
HM Coastguard has now produced a free identification sticker that owners can write their contact details on and stick on their vessel.
Anne Young, HM Coastguard's National Liaison Officer for canoes and kayaks, said: "We recommend that you clearly mark your canoe or kayak with your name and contact details so that if it is lost, stolen or abandoned we can contact you to make sure that you are safe.
"This will save a lot of time, and could give us extra information we need to help you if we believe you're in difficulty at sea.
She added: "For canoeists and kayakers, our other safety advice is to wear a buoyancy aid and make sure you carry a VHF radio, so you can contact the Coastguard on channel 16 if you get into difficulty.
"And remember to tell a shore contact where you are going and when you expect to return so that they can contact us."
HM Coastguard will be at the Paddle Show at Bells Sports Centre, Perth this weekend.
