Wow, Dave, 2 posts on this list and you've manged to hit almost every HOT BOTTON!

Congratulations, that is a new world record! :twisted:
Kidding aside, welcome aboard. Most of us had those same questions as you (what boat should I buy and how many motors should I put on it???). Here's my take: most folks will suggest you buy what they bought, 'cause they know it suits their situation. We don't know your situation, though. Spend some time going through the archives here and you will see COUNTLESS posts on the two topics you asked about... really, you will be able to read for hours... and you still won't have a definitive answer. 'Cause in reality, the right boat and twins vs single will depend on you. You can make any combination of those two work (many here are living proof of that). How's that for a CAN'T LOSE situation?
So, my advice to you is: don't buy either until you know a bit more about what you will do with the boat. Many of us agonized with these very questions for months. :wink: And in the end, we bought the boat that is right for the way we use it... or perhaps we use in a way that works good with the boat? I hope you're getting my drift... spend some time here; go to a gathering. The Seattle Boat Show is a great opportunity to see both boats and talk to LOTS of owners face-to-face. We flew in for it two years ago just to do that and came home as the happy owners of a scheduled-to-be-made boat.
Good luck with your decisions. It's part of the fun. Really. OK, cruising on the boat is WAY more fun. :wink
Best wishes,
Jim B (CD-25 with a single Honda... and darn happy with that decision for the way we use our boat)
PS - Speaking of "hot button", perhaps the question would be better presented as "which boat would better fit our needs" instead of "which is better"? 8) Oh, and what's up with your profile? It implies you already have a 2008 CD-25. Or, is that an aspiration?
