Zodiac Mark II ST 2009 vs Zodiac Zoom 400 SR 2007 — Same Brand, Different Boat

The Zodiac Mark II ST 2009 vs Zodiac Zoom 400 SR 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Both boats share a closely matched power ceiling — 40 hp for the Zodiac Mark II ST 2009 and 30 hp for the Zodiac Zoom 400 SR 2007. 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 boats are rated for 7 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Zodiac Mark II ST 2009 and Zodiac Zoom 400 SR 2007 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Zodiac Mark II ST 2009 vs Zodiac Zoom 400 SR 2007 — Common Questions

Which is the larger boat — the Zodiac Mark II ST 2009 or the Zodiac Zoom 400 SR 2007?
The Zodiac Mark II ST 2009 is the longer of the two at 13,8 feet overall. The Zodiac Zoom 400 SR 2007 comes in at 13,0 feet, making it roughly 0,8 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Zodiac Mark II ST 2009 is rated to a maximum of 40 hp, giving it the larger power ceiling. The Zodiac Zoom 400 SR 2007 tops out at 30 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Zodiac Mark II ST 2009 is Coast Guard rated for 7 passengers, while the Zodiac Zoom 400 SR 2007 is certified for 7. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Are the Zodiac Mark II ST 2009 and Zodiac Zoom 400 SR 2007 from the same manufacturer?
Yes — both the Zodiac Mark II ST 2009 and the Zodiac Zoom 400 SR 2007 are built by Zodiac. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
