When two boats share the same hull type — in this case both the Zodiac 690 2009 and the Zodiac Yachtline Deluxe 470 DL 2012 are inflatable rigid designs with inflatable 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?

The power gap is worth calling out. Rated to 250 hp, the Zodiac 690 2009 has a 160-hp advantage over the Zodiac Yachtline Deluxe 470 DL 2012's 90-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 690 2009 is rated for 12 passengers, while the Zodiac Yachtline Deluxe 470 DL 2012 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac 690 2009 could be the deciding factor.

The Zodiac Yachtline Deluxe 470 DL 2012 has a documented top speed of 42 mph. Speed data wasn't available for the other model.

The Zodiac Yachtline Deluxe 470 DL 2012 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Zodiac 690 2009 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
