Information on a Kanter Atlantic 45, 1987

[atlantic high]

I just purchased a Kanter Atlantic 45 (1987), with a few rust holes is the bottom. These rust spots are only where water dripped for years, like under the head/ shower, galley sink, anchor locker ect. The rest of the bottom is perfect, inside and out. I started out thinking I should patch the holes, but now I,m going to take out the floor and cut out the bad spots/sandblast and weld in new metal. I have been told the builder (Kanter) is one of the best in the world? The motor is a volvo penta TMD 30 A (90 hp). The boat is in the great lakes, and the former owner did No maintence. I have been looking for info on the boat and motor , like history, problems, what to watch for, any info about this boat and motor would be really helpful. I have a big project ahead, and any tips on attacking this project would be helpful. It also has a teak deck, so far it looks perfect, but I think I should glass it over before its developes a leak, any leak in this boat is going to be dangerous, do I really need to take all the teak off the deck if its in good condition, can I just lay 24 ounces of glass over it with west system? Also can I replace the steel water tanks with stainless when I have the floor out? thanks for your time . atlantic high
