I am in the market for a late model used boat in the 26 to 29 range down to these four help??/

The 26' Sonic is really a 25 with a molded swim platform and wings on the side of the hull to support it; I will be honest about that. However, I have been on all of the boats you mentioned, and for room, value, standard amenities, beat-the-tar-out-of ability, and overall comfort, there is no doubt in my mind... Sonic.

(OK, I like my 26' Prowler.)

Out of those choices I would go with the Sonic.

Hey buy my boat it is a true 26' !

I would definitely check out a 28' Active Thunder!!

And the 288 Sunsation...

I voted Sonic so you could buy my buddies 260 Prowler. Great boat and I have had a lot of fun on it. Dont give up on it just yet.

I have the 26ZX and would not trade it for any of the others mentioned above. I have just the stock 502 in it right now and it may not be the fastest out there but from what I seen it handles the bigger water better.
But this is just one loyal Donzi owners opinion.

Only downside to the Sonic is no windshield and a narrow cockpit only 3 across the back seat. I,m in a hold right now I think until after the NYC boat show. I hope they have a Sonic there

All of the above boats a very nice, you need to ask yourself how often you will be spending the night onthe boat. 27 Fountain is cramped in cabin. However the Sonic is roomy but a heavier boat. No one kill me here but the Fountain is probably the fastest of the bunch, but not by much. I very rarely spend the night on my boat so it works for me.

PS my second choice would be the Sonic

Will

Which one has the largest (most comfortable) cabin?

Which one would have the most comfortable ride in a 2 to 3 foot chop?
