Also, percentage may not be the way to look at it. If 2 guys both heve a 45 foot yacht but one was bought new and top spec for Ł300k and another guy bought an older and say run down one for Ł80, then obviously the 80k guy is going to be spending a higher percentage and perphaps more even in absolute terms.
We're personally at some point in between. For example I'm going to have the bite the bullet at some point and replace the teak decks but I was aware of this pending expense at the time of purchase.
