When two boats share the same hull type — in this case both the Cruisers Yachts 390 Sports Coupe 2010 and the Cruisers Yachts 520 Express 2010 are semi displacement 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 Cruisers Yachts 520 Express 2010 measures 52,3 feet overall (2010), giving it roughly 12,1 additional feet of deck space compared to the Cruisers Yachts 390 Sports Coupe 2010 at 40,2 feet (2010). At 22 lbs and 42 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.

The power gap is worth calling out. Rated to 715 hp, the Cruisers Yachts 520 Express 2010 has a 295-hp advantage over the Cruisers Yachts 390 Sports Coupe 2010's 420-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 3 gal and 5 gal — so range won't be a tiebreaker here.
