When two boats share the same hull type — in this case both the Riviera Yachts 48 Offshore Express - Open 2011 and the Riviera Yachts 73 Motor Yacht 2011 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 73 Motor Yacht 2011 measures 73,5 feet overall (2011), giving it roughly 23,7 additional feet of deck space compared to the Riviera Yachts 48 Offshore Express - Open 2011 at 49,8 feet (2011). At 43 lbs and 105 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 — 715 hp for the Riviera Yachts 48 Offshore Express - Open 2011 and 700 hp for the Riviera Yachts 73 Motor Yacht 2011. 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.

For family outings this is probably the sharpest distinction between the two. The Riviera Yachts 73 Motor Yacht 2011 is rated for 22 passengers, while the Riviera Yachts 48 Offshore Express - Open 2011 caps at 15. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Riviera Yachts 73 Motor Yacht 2011 could be the deciding factor.
