That "little lower" is 25%-40% or so.
And then just about two weeks ago I worked with a guy to buy C30 in excellent shape with several extras for I think it was 11,200
It sold cheap because it had a raw water cooled Universal that scared off most people. The motor was rebuilt about 5 years ago and seemed perfect.
Time will tell.
I don't know what my point is except that it seems like there is a wide variation in pricing.
I just looked at the last 20 Catalina 30's sold and they averaged 19k, lowest was 11,200 highest was 27k
I think that the very best value is often the most expensive boat.
Let's say for example you are in the market for a Catalina 30 know they generally go for about 20k.
You find one that in the last 5 years has had. Hull barrier coated, Keel removed and re-bedded and keel boats checked or replaced, Topsides and deck is clean, Winches replaced with two speed self tailing, Hatches and port-lights replaced, Thru-hulls replaced, Custom anchor mount installed, new modern anchor and 30' chain and 200' rhode, new Bimini and dodger, New Beta diesel, new water and fuel tanks, rewired to abyc standards, New windex, depth, radar and electronic package, new standing and running rigging and replaced chain plates, new sails and roller furling and covers and interior cushions.
If the the guy wanted 30k and you had the money that would probably be an awesome deal assuming it didn't have soft decks or a leaky hull deck joint or some other boat deal killer.
The sad thing is that the guy would probably be hard pressed to get 30k for a Catalina 30 that he just put well over 50k into.
As someone has already said the consumables on a boat can easily be worth more that the boat once it is over 20 years old.
The way I explained it to the guy who just got the boat for 11,200. Buying an old boat is like playing Russian roulette only the gun has 50 chambers (The actual risk is unknown and depends on the boat) and only one bullet. Every time you go out you pull the trigger. Most of the time you go sailing and come back, no problem, sometimes something goes boom and you have to fix it.
Another guy I'm working with just bought a Bristol 32. Started it up for the first time and noticed the raw water pump was seized. Boom the bullet was in the chamber, who knew. Costs a few hundred.
