Matching a inflatable rigid Zodiac Sundream 2009 against a inflatable non rigid Zodiac Zoom 350 S 2012 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
The power gap is worth calling out. Rated to 80 hp, the Zodiac Sundream 2009 has a 60-hp advantage over the Zodiac Zoom 350 S 2012's 20-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Zodiac Zoom 350 S 2012 is rated for 5 passengers, while the Zodiac Sundream 2009 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Zoom 350 S 2012 could be the deciding factor.
The Zodiac Zoom 350 S 2012 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Zodiac Sundream 2009 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: Choose the Zodiac Zoom 350 S 2012 if your priority is putting more people on the water — it handles 5 passengers and at 11,5 ft it has the deck room to back that rating up comfortably. The Zodiac Sundream 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
