When two boats share the same hull type — in this case both the Zodiac ProJet 350 TC4 2010 and the Zodiac Yachtline Deluxe 380 DL 2011 are inflatable rigid designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department — Zodiac ProJet 350 TC4 2010 at 11,5 ft versus Zodiac Yachtline Deluxe 380 DL 2011 at 12,5 ft. Weight tells a clearer story for trailering families: the Zodiac ProJet 350 TC4 2010 tips the scales at 661 lbs — 180 lbs more than the Zodiac Yachtline Deluxe 380 DL 2011 at 481 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The power gap is worth calling out. Rated to 98 hp, the Zodiac ProJet 350 TC4 2010 has a 48-hp advantage over the Zodiac Yachtline Deluxe 380 DL 2011's 50-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 12 gal and 9 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Zodiac Yachtline Deluxe 380 DL 2011 is rated for 5 passengers, while the Zodiac ProJet 350 TC4 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Yachtline Deluxe 380 DL 2011 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac ProJet 350 TC4 2010 comes in at 7 lbs per hp versus 10 lbs per hp for the Zodiac Yachtline Deluxe 380 DL 2011. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Top speed is rated at 44 mph for the Zodiac ProJet 350 TC4 2010 and 34 mph for the Zodiac Yachtline Deluxe 380 DL 2011.
Bottom line: Choose the Zodiac Yachtline Deluxe 380 DL 2011 if your priority is putting more people on the water — it handles 5 passengers and at 12,5 ft it has the deck room to back that rating up comfortably. The Zodiac ProJet 350 TC4 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
