I can say I rode on both boats, and ended up purchasing the 232 ultimately.
Each has its pros/cons I will list my thoughts below:
228 w/ Single 250 Suzuki
Pros:
Ride:
Upsea- shorter interval chop more comfortable less pounding.
Trailerability:
Lighter and shorter beam, easier to tow with 1/2ton pickup truck.
Fuel Economy:
I feel this is subjective to sea state, etc. But defiantly more fuel efficient.
Cons:
Smaller Cabin with less headroom
No step up “express style” command bridge
Wet ride in sporty conditions
Rear seating and live well take up cockpit area
Lower gunnel height (this could also be a pro depending, I have small children so I felt higher gunnels were better for my situation)
Tight between the helm and passenger seats (beam issue)
Shorter windshield (this is not confirmed, I feel that to me the windshield is shorter)
Lavatory Facilities (even though we particularly don’t use them, it’s better laid out on the 232)
No Large fish box
No options for twins (or I haven’t seen any factory. I guess you could add a different bracket and add twins aftermarket)
A little tight fishing more than 3 guys on it.
232 twin F150’s
Pros:
Wide beam
Larger cabin ( bunk is nice for my older child)
Better setup for overnighting
Large fish box on transom
Dryer ride (this may be due to wider beam and more bow flare)
Fold down aft bench (nice for family outings, or completely fold down for fishing)
Higher gunnels ( see reasoning above)
Weight (no replacement for displacement)
Twin Power (lots id)
Better field of vision ( possibly due to windshield height and step up)
More hatches for quicker bilge access
Cons:
Trailering:
Wide beam may require special permits.
Heavy (pretty much this boat is about 10k loaded, fuel, ice, gear. This pretty much pushes the limits of a half ton truck)
Ride
Up-sea:
Steep swell short trough: this boat pounds easier than the 228. There needs to be more care in weight distribution, trim, and tabs. (This being said the 228’s aux fuel tank and fresh water space was converted to a large fish box. The 228 was an ‘06 model which had the main tank further back. This space was usually full 300+lbs with ice, water, fish etc, which moved more weight forward which helped keep the bow down)
Bow rise (I feel there is much more bow rise on the 232 to get on plane)
Underpowered ( I feel this model runs better with twin 200’s. The 150’s get the job done, but in certain sea states struggle.)
Fuel Efficiency (compared to the 228)
Both boats I feel are class leading in this size range. I feel downsea, they both have similar excellent ride characteristics.
IMO the 232 is a good upgrade to the 228, if you’re looking for a larger cockpit, the redundancy of twins, a still trailerable (sort of) boat. It will give you that big boat feel (within reason) that’s still manageable single handedly. Don’t get me wrong, if I had the space, and a slip I would definitely be in a marlin. I keep my boat in my driveway, and trailer it to put it in the water, so this I felt this was the best “trailerable” boat that fits my needs.
Keep in mind, the 232 boat has tiny tabs for its size. Soon I will be upgrading to 12x12’s. When I’m trying to get the bow down to lessen the pounding, I’m putting the brakes on I have them deployed so much. But I understand you’ve upgraded your tabs on your 228, so you have experience with this.
