When two boats share the same hull type — in this case both the Zodiac Bayrunner Pro Series 2011 and the Zodiac ProJet 420 TC4 2008 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 Bayrunner Pro Series 2011 at 13,8 ft versus Zodiac ProJet 420 TC4 2008 at 13,0 ft. Weight tells a clearer story for trailering families: the Zodiac ProJet 420 TC4 2008 tips the scales at 904 lbs — 822 lbs less than the Zodiac Bayrunner Pro Series 2011 at 82 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 Zodiac ProJet 420 TC4 2008 tops out at 98 hp. Engine specs for the Zodiac Bayrunner Pro Series 2011 aren't listed — confirm with a dealer before selecting an outboard.
For family outings this is probably the sharpest distinction between the two. The Zodiac ProJet 420 TC4 2008 is rated for 6 passengers, while the Zodiac Bayrunner Pro Series 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac ProJet 420 TC4 2008 could be the deciding factor.
The Zodiac ProJet 420 TC4 2008 has a documented top speed of 40 mph. Speed data wasn't available for the other model.
Bottom line: Choose the Zodiac ProJet 420 TC4 2008 if your priority is putting more people on the water — it handles 6 passengers and at 13,0 ft it has the deck room to back that rating up comfortably. The Zodiac Bayrunner Pro Series 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
