Oh my gosh: Changes? Where do I start? Friend has an '87 35 (that's Thirty Five), and I have a '89. There are so many differences I could not begin to list them from memory. And, I know both boats very well. They did not all have CNG. Dan's boat does but mine has all Origo cooktop and oven, Dan's does not have an oven. That's just the beginning. Dan's has a single round galley sink, mine a double square one. Dan's has a lavatory in V-berth, mine does not. Dan's gelcoat all white, mine is white and gray. There are even minute differences between the cockpit mold that both ours were laid up in. Once, I was rafted up with Dan's boat, rowed out and took pictures, Dan's mast appears about 18 inches higher than mine. There many, many more differences. BTW, those were 35's not 35.5's that were in that racing league. And, there was never any aluminum tankage in my vessel. It's all plastic and original except for holding tank that I upgraded to 30 gallon and relocated.
There is also a '95 Model 35.5 on our docks, and hardly anything on or in it resembles our older 35 Legends. Big differences, some not always for the best...
