thx. I’m going to bring a tape measure with me and go see more used boats. I just thought it may have been a question someone answered already. ThxHere are some excerpts from a Boating Magazine review of a 2007 305. This is comparing the Express to walkarounds so it doesn't cover the 330 specifically but you can find reviews with the deck deck area for both boats
YOU SNOOZE, YOU LOSE. The concept behind making a 30' express instead of a 30' walkaround is to regain the interior space lost to recessed sidedecks, and this boat makes great use of that space. The cabin feels airy and usable, especially due to the V-berth design. More accurately, it should be called a horseshoe berth. This area of the boat was redesigned to make it more usable as living space, as opposed to sleeping space. If you want maximum berth size, stick with the V. But by rounding the peak, expanding the seating area aft, and mounting a round table in the middle, this slice of the boat is much more comfortable for those people who are upright and conscious. Four can easily sit around the dinette, and when it's collapsed and capped with the filler cushions, there's plenty of room for a couple to snooze at anchor.
Got kids? Throw them in the midcabin. There's not much headroom under the helm, but Grady-White thoughtfully mounted a set of rodracks in the overhead, so you can safely stow four Internationals. Good thinking; in my experience, midcabins are usually used for stowing more than sleeping, and with those racks in place and eight more rigs lying on the cushions, your entire arsenal will fit down here.
High Points: The V-berth is a horseshoe berth, and it's better living space. No matter where you are, there's a grabrail within reach. Windshield supports are the size of the hardtop pipework on some lesser boats.
Low points: The V-berth is a horseshoe berth, which means less sleeping space. Anchor locker access from the cabin requires screw removal, which will be difficult at sea. Water sloshed out of the livewell while underway in rough seas.
You can sort of compare the layouts using the brochure for model year 2007
