The business is not all smooth sailing—regulation, for one thing, varies widely.
French law allows boatsharing, but in Greece, a tempting market, private owners face more difficulties.
Renters usually need a boating licence, or must hire skippers. Demand to get on the water is seasonal.
Building up a big fleet of boats takes time. Owners tend to be middle-aged and are reachable mainly by word of mouth or at boat shows.
Undeterred, both firms are trying to scale up, partly by pursuing a flotilla of potential rivals.
Click&Boat bought one, Sailsharing, in 2016, to access more craft.
Boatsetter has gobbled up American startups including one last year, Boatbound, that Click&Boat also eyed.
In April the American company added Smart Charter Ibiza, a conventional charter firm, in Spain, part of a move into the Mediterranean.
四月，该美国公司加入Smart Charter Ibiza（一家西班牙常规租赁特许公司），其业务部分涉及地中海地区。
Boatsetter has also developed an insurance product, with a third party, for peer-to-peer rentals,
and has partnered with Airbnb to offer experiences such as wakeboarding in Miami or eating paella on a boat near Barcelona.
Click&Boat has started a separate site, Click&Yacht,
for chartering luxury craft for thousands of euros a day in places like the Cote d'Azur, for which there is plenty of international demand.
It is one thing to stay in someone else's flat. It's another to captain a superyacht—especially when it looks like you own it.
