Taughtline Hitch knot

For our Whetu Survivor, the Extreme team had to learn how to tie knots for my second knot I tied a Taughtline Hitch knot. I found this knot partly easy because some parts were really easy but some parts were a bit challenging and confusing so that's why ill give this knot a difficulty rating of 3/5. I did some research on what you could use this knot for and it said it can be used for lines under tension.
