I’m in the US, but somewhat ironically my DH and I are thinking of setting something similar up to this in a few years. It’s a unique situation and we’d be catering to a very specific group.
Essentially it’s an area that has several (8-9 ) passenger boats that do summer cruises - small historical sail. The boat kids (20-somethings) crew these boats are a nomadic bunch that travel from contract to contract with very little in the way of possessions.
We are planning to move to the area in a few years and if we can find the right house we want to offer up this type of lodging for the kids. We floated the idea to the crew one year (no pun intended) and they loved it.
Most of the time they are sleeping on board, they only need accommodation random nights and during the full time at the front and end of the season. They will then move on to other contracts in warmer places for the winter.
They need a place to wash clothes, maybe store a car, and they don’t want to fool around with cooking or cleaning when they at port. If we do it we’d offer basic accommodation (bed and a wardrobe), linens, cleaning, and meals.
Right now a bunch of them will rent a place and all contribute, but that comes with all the drama you’d expect for people coming and going and with no real full time residents.
We don’t expect to profit from this. If we can make enough to break even we’d be ok. It’s more about getting into the community.
