I closed my account
About three and a half years ago, I had thought of doing the same thing, only I was gonna build my own raft out of 5-gallon water bottles and other upcycled materials.
I even had a friend of mine with an engineering background help me out with the design of the raft, to ensure its seaworthiness.
PLEASE keep us updated on how this idea (hopefully) pans out, as I would LOVE to hear/read a first-hand account of such an epic journey.
Believe it or not. Someone made it down the river in 2016 on a trash raft lol. 2 liter bottles and whatnot.
I pictured you in more of a longboat than a raft though.
