We have concerns about all types of vessels. It's about the scale of risk.
As I've mentioned several times, a canoe or a kayak is easy to dry. There isn't necessarily a confined space where water can accumulate, so it can be drained quite easily. So those kinds of vessels are less of a risk. The risk is always there, but it's a matter of reducing it.
Fishing vessels that contain tanks or boats for water sports that contain closed spaces, for example, are high-risk vessels.
