While reading this thread and a recent one looking for a water taxi I thought: How about Uber for on the water?
Many of us look for any excuse to take the boat out. Fetch a newspaper or milk? Go to lunch? Take a ride? Go to the laudromat? No problem, we're ready! If anyone needed a ride we'd line up to volunteer.
What if you could earn a little gas money by being a water taxi for all those island residents while finding new excuses to be on the boat? You'd just tell your Liquid Uber app that you're available and those needing rides could see where you were.
If Uber works on land why not on the water? I'll have to write to Uber's suggestion box...or seek some venture capital funding!
