The taughtline hitch lacks the tuck so it has a somewhat different structure from the rolling hitch.
I usually put three round turns at the bottom of it when friction is needed. You can put as many half hitches at the top as you feel like. I didn't know that this makes it a "camel hitch", but whatever.
Remember the basic taughtline hitch is just a clove hitch with an extra round turn at the bottom (or two).
The rolling hitch is just a taughtline hitch with one of the round turns at the bottom tucked inside the other.
All these knots are close relatives.
I've noticed that in the U.S. many sailors tie their rolling hitches like taughtline hitches.
