Hello and Welcome! Tons of info to absorb so keep reading. Hammock camping is not necessarily lighter than tent camping. A tent, sleeping bag and pad is often in the same weight range as a tarp, hammock, top quilt and bottom quilt. The biggest gain is in comfort. A better night's sleep equates to a better day hiking or paddling and overall more enjoyable outdoor experience IMO. A hammock also serves to provide more comfortable sitting/lounging at camp.
Don't let life get in the way of living.
