What is the difference between a single and double strand hammock?

Most hammocks you work on will be single strand. Aerial yoga hammocks are all single strand. The double strand hammock is essentially like having two single strand hammocks in the one apparatus. It provides more opportunities for complex wraps and positions. A double strand hammock needs the same rigging as for a single strand hammock. The double strand hammock is recommended for partner work as it is close to twice as strong as a single strand hammock.
