It depends on the boat, lol ! On this one, 50% of US$ 275'000 for one week. I think you can do the maths, even if you're not the best with google ? :)
(FYI : on google, search with : Lady Michelle super yacht charter)
Late to the party, but... for my last birthday on June 10th, my husband has asked one famous painter artist -who is also one of our closest friends- to do a portrait of his favourite picture while I was modeling (~1986, lol !). I love it, tbh !
I hope it's ok to post this link, but this guy reviews all the episodes with cultural references, time codes, etc., and it's amazing the amount of work he puts in it :
FYI, the previous episodes are linked in his post too ! It's worth it.
