If you don't have the time to look after her at the moment, don't go and look at the boat. It's called "tyre-kicking", and is extremely frustrating for the vendor, who has to give up valuable time to talk to someone who knows that he won't buy the boat. Do everyone a favour, and wait until you have the resources to do a boat justice. Believe me, even then you won't have all the resources.
