Being able to effectively use both rope and tape is an essential skill for any paddler. The best way to gain these skills quickly is to get signed up on a course with an approved provider. The guys at Boreal River Rescue have shared some really useful information that is well worth checking out. This one relates to knots used on both rope and tape used in rescue situations including the figure 8 family as well as alpine butterfly and water knot.
They key to all things like this is to get practice so when/if they have to be used in anger they can be set up quickly and correctly.
