>>1218298You...fold up you boat? You’re going to need a public access boat launch on either side of your commute. You can’t just haul your boat up on private property, let alone that the shorelines of major cities are built up with concrete bulkheads. Also, boats are heavy. Motors are heavy, and using a motor is the only way you’d be able to commute in any manner of timeliness. It’s not exactly something you can fold up and carry like a folding bicycle. Something like pic is the closest I can see being applicable to what you’re asking, and it would be a huge pain and added time to inflate/deflate and break down on either side of your commute.
And please don’t consider crossing busy shipping lanes by oar twice a day.
