@Rebecca181
Many hosts around the world do it but, by far the majority of those listings are 'static'. Are you suggesting you will be doing the same thing here, simply having it listed as a berthed live-in, or will the opportunity to sail be involved?
I don't think I would want to try what you wish to do in America, Rebecca.
Too many regulations, and a society that is simply too litigious....many more opportunities for problems on a boat, particularly a small one.
I have an interest in a 65ft houseboat on the River Murray which I had intended to list on Airbnb, but the management company being used who specialise in river houseboat rentals is keeping it fully booked and the opportunity to list here has not offered itself.
I don't have to worry about security deposits (bonds) continuity of bookings or anything concerned with the river regulations, that is all taken care of which does take the lions share of the rental amount and being fully air conditioned, bookings are steady year round. Also this is in a river, not the ocean, and is more like a house than a boat. So the potential problems are reduced enormously.
This was not a massive risk for me Rebecca but, I don't think I would be wanting to do what you are contemplating.
Cheers.....Rob
