If he is stripping all the good stuff off the boat, make sure the inventory is actually up to the task. You don't want to be immediately spending money on basic things like warps, fenders, safety gear, a handheld VHF, etc etc.
I have been advising KentishPirate by Private Message. All your comments are reinforcing my private comments about this Centaur. He has now spotted a Konsort for sale on the Medway and is trying to get details and the price. It may not be within his budget, but would certainly meet his original requirements and probably give him a boat he would keep for longer. The Konsort is a much later design than the Centaur, so newer than a Centaur and about double the price for a good one.
