All the boats mentioned here are good choices. I would not say the Fountain is the best rough water boat out there (but will do whatever we will be using them for). I would look at a few others first. Cigarette and Outerlimits will be your top choices for a V-hull. Both cost alot up front but will hold their value better than others. They crush Big water. Skater, Nor-Tech, MTI will be your best in the cats. Pricey, but again hold there value well. I like Photo's boat. Nice colors. I just have never been a Fountain fan (the style). Everyone likes a boat for different reasons. Find your reasons and that will lead you to the boat for you. Good luck. Shopping is great!
I am with Trigger! I am not real sure about performance comparisons. I think the Fountain is pretty fast but all the ones that I have been in dont seem real solid. Though I cant give a true comparison since I have not been in the Cig or Outerlimits. Just my 2 cents.
