I have never seen a De Fever or if I have, I did not know what it was. Bought an 87 GB32 fall of 2017 and it surveyed well, although it was on the hard, winterized and the surveyor could not start it on the hard. In the fall when we saw the boat we went through it ourselves before it was taken out of the water and started the engine and checked out the transmission. The yard's mechanic went through it with me and answered lots of questions. I have done a lot of mechanical work on boats. Here comes the bite: Before Boat U.S. would insure it we had to go through the various systems and update a lot of stuff, like the ventilation and detection system for the propane stove. New batteries. New below-water-line hoses, and on and on. So the bottom line: Whatever you pay for it, expect a bunch of investment before you get it on the water unless you want to just leave it tied at the dock like our boat's previous owner. The quality of the Grand Banks was far more than skin and furniture deep -- its mechanical systems and wiring are exceptional. Things are easy to repair and replaceable with standard items that are still on the market. And this was a boat that was, as it stood there IN EXCEPTIONAL CONDITION. Another point: check out the access to the storage places throughout the boat. Our GB has lots of under-seat storage, but you have to crawl around on the floor opening little vertical trap doors to get things out. Now I am having to reupholster all the seats because I must have access from above -- cut hatch holes in the plywood under the seats and put in removeable lids. These are some things to think about. In the end, you cannot go wrong with a good Grand Banks.
