Since there have been no 2010's produced, we have no idea what changes if any there will be. Since Sea Sport has said they will be building the line unchanged, I would assume that the 2010 will be the same as the 2009 boats.
Biggest difference will be that the 2010 boats, when produced, will have a factory warranty on the hull, and the 2009's do not. (Sea Sport has made the decision not to assume the warranty obligation on boats they did not build).
However, I would imagine that you could save a sizable amount on a 2009 if a dealer has one in stock- enough to make self warranting the hull an attractive option. The engines, and other bolt on items will still carry their factory warranty, usually one year (three for engines).
You might check with Wefings, as he had a couple of these in stock, and would probably make a great deal on them.
