Review I paddled an 06 4fun probably 45 times last year and loved the boat. Just a few weeks ago, it developed a crack in the bottom. JK warrantied it, I payed for the upgraded hull and took home the new 07. I took it on the Muddy river in Washington state last weekend and I was delighted to see that the new hull is indeed much looser than the older version. The outfitting is pretty much the same, however I did need to move the seat all the way forward to get my knees in the correct spot. I did not suffer any trim problems in doing this. I chose the 4 fun again because I do more class III/IV- in it than playboating. If this wasn't the case, I'd have gotten the Fun. Conclusion The 07 4Fun is still a great boat, the hull is looser and did seem easier to roll, not that the older version was hard. I only gave it a 4.5 because there is always room for improvment....
