Is there a risk that my SUP paddle will snap?
It is possible for any paddle to snap, but it's not common for paddles from reputable companies. The low-end aluminum adjustable paddles are notorious for this, so we recommend they only be used as travelers, not as an everyday paddle. Also, some of the off-brand, package deal carbon-fiber paddles are notorious for snapping. I had one snap the second day I used it, right at the joint between the blade and the shaft. It was just overall a bad joint design.
On our Tower carbon Kevlar paddle board paddle, we don't have any record of our carbon Kevlar paddles snapping as they are a tougher material than 100% carbon fiber. On the low-end, the inexpensive fiberglass SUP paddles we carry are super durable workhorses as well.
The take away here is that it's smart to invest a little money in a decent paddle, for both performance and safety concerns. You never really want to have a paddle snap when you're out paddling by yourself.
