When two boats share the same hull type — in this case both the Riviera Yachts 5800 Sport Yacht - IPS 2013 and the Riviera Yachts 5800 Sport Yacht 2012 are deep vee 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?

Size is the most obvious dividing line here. The Riviera Yachts 5800 Sport Yacht - IPS 2013 measures 63,0 feet overall (2013), giving it roughly 5,4 additional feet of deck space compared to the Riviera Yachts 5800 Sport Yacht 2012 at 57,6 feet (2012). At 46 959 lbs and 46 959 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 — 435 hp for the Riviera Yachts 5800 Sport Yacht - IPS 2013 and 435 hp for the Riviera Yachts 5800 Sport Yacht 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 — 7 gal and 7 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Riviera Yachts 5800 Sport Yacht - IPS 2013 is rated for 19 passengers, while the Riviera Yachts 5800 Sport Yacht 2012 caps at 17. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Riviera Yachts 5800 Sport Yacht - IPS 2013 could be the deciding factor.
