Boat Canoe Sponson Kits
When resting on the water, or participating in active sport or fishing on canoes, it is always worth remembering safety. Watercrafts like canoe and kayak are not very well balanced and there is a high risk of rollover and tilting when sailing carelessly. To minimize the risks, additional attachments in the form of side sponsons can be mounted, which significantly improve stabilization. Sponsons add flotation to help keep the canoe afloat and add additional stability. Sponsons might save your canoe, and might even save the life of a person clinging to an overturned boat. Thanks to this equipment, capsizing a boat is almost impossible. Sponsons have several distinctive features in this regard: lightweight; excellent buoyancy (hold well on water); durability; UV protection; easily maintained. Boat canoe sponson kits usually include two sponsons and all the necessary hardware. Sponsons come in one length suitable for boat of different brands.

  1. Whenever I am taking my boys out on our canoe I always use our sponsons. It gives me extra comfort that they can’t accidentally tip the canoe as easily as without them. I’d rather not have to explain to my wife why our sons came back soaking wet and freaked out. I use the brand Grumman Canoes and they have served us well for the past couple of years.
