This is the rubber raft I rescued from the deep. I took it around the harbor and shot this video after cleaning it up and patching the holes with gorilla glue and duct tape. When we were kids we used to turn anything into a boat, pieces of wood, old boxes, garbage bags full of sawdust, you name it. For safe boating you will need to bring a life jacket. I also recommend a bailing can, spare set of oars, and a flotation cushion.
I have less than $50 invested in this boat and motor, but batteries are spendy. With a solar charge controller and proper care, deep-cycle lead/acid batteries will last for years.
johnsolar had an idea. he suggested making a “battery charger” from “solar garden lights”. last year i did an “experiment” with these solar garden lights and realized the potential to “charge batteries” for “free. i decided to go the next step and disassemble the garden lights and see if i could use the “solar panel” and battery holder only. this was a success and i will buy more of these and do a better job of building the box and soldering all the joints. “offgrid” “grid down” “shtf” “teotwawki” “wrol”
