Allegedly, leasing costs are 1% of hull value per month (ish). So, depending on the length of the lease, hull value, coriolis value 55 north, say $30,000 per month. However, leasors want to know for sure that you are good for that so, you generally also pledge a testicle or two as a deposit! And once you have got the thing, then you realise that have just become an invoicing address. Good luck!
