I got the brochures from Polar kraft and not very user friendly on the info I was looking for. I did compare the 2009 to the 2010 model on line. The 2010 is .125 aluminum like the sea ark with same warranty. The 2009, you could get the 65gal livewell that I want but doesen't say on the 2010, I'm sure it's available. I want the larger deck in the back for spider riggin crappie. Prices I have seen with a 140hp is considerably cheaper than sea ark. I believe a 150hp can be put on if you upgrade the steering. I just have to move my ass and see a dealer and get the real lowdown. The ole boat I have is getting rough, rode hard and put up wet for yrs but a bunch of pigs have hit the deck.
