When two boats share the same hull type — in this case both the Riviera Yachts 43 Offshore Express - Open 2011 and the Riviera Yachts 50 Enclosed Flybridge 2013 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 50 Enclosed Flybridge 2013 measures 56,5 feet overall (2013), giving it roughly 11,0 additional feet of deck space compared to the Riviera Yachts 43 Offshore Express - Open 2011 at 45,5 feet (2011). Weight tells a clearer story for trailering families: the Riviera Yachts 50 Enclosed Flybridge 2013 tips the scales at 50 706 lbs — 50 430 lbs less than the Riviera Yachts 43 Offshore Express - Open 2011 at 276 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 power gap is worth calling out. Rated to 442 hp, the Riviera Yachts 50 Enclosed Flybridge 2013 has a 72-hp advantage over the Riviera Yachts 43 Offshore Express - Open 2011's 370-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 Riviera Yachts 50 Enclosed Flybridge 2013 is rated for 17 passengers, while the Riviera Yachts 43 Offshore Express - Open 2011 caps at 13. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Riviera Yachts 50 Enclosed Flybridge 2013 could be the deciding factor.
