When two boats share the same hull type — in this case both the Zodiac Yachtline Deluxe 340 DL 2012 and the Zodiac Yachtline Deluxe 380 DL 2012 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 Yachtline Deluxe 340 DL 2012 at 11,2 ft versus Zodiac Yachtline Deluxe 380 DL 2012 at 12,5 ft. At 426 lbs and 481 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling — 40 hp for the Zodiac Yachtline Deluxe 340 DL 2012 and 50 hp for the Zodiac Yachtline Deluxe 380 DL 2012. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 9 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 2012 is rated for 5 passengers, while the Zodiac Yachtline Deluxe 340 DL 2012 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 2012 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Yachtline Deluxe 380 DL 2012 comes in at 10 lbs per hp versus 11 lbs per hp for the Zodiac Yachtline Deluxe 340 DL 2012. 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 34 mph for the Zodiac Yachtline Deluxe 380 DL 2012 and 30 mph for the Zodiac Yachtline Deluxe 340 DL 2012.
Both are inflatable designs, which means they pack down for compact storage, can be carried in a bag, and are dramatically lighter than equivalent rigid hulls. The trade-off is setup time and the need to monitor tube pressure regularly.
Bottom line: Choose the Zodiac Yachtline Deluxe 380 DL 2012 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 Yachtline Deluxe 340 DL 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
