Sea Ray Boats, America's Best-Known Cruiser Brand

From Detroit to Knoxville

Cornelius Ray founded Ray Industries in Detroit in 1959, and the Sea Ray brand grew into one of the largest builders of fiberglass pleasure boats in America. The company opened a major plant on Merritt Island, Florida, in 1973, and Brunswick Corporation bought it in 1986 for $350 million. Sea Ray is now headquartered in Knoxville, Tennessee, with factories in Tennessee and Florida.

Brunswick tried to sell Sea Ray in 2017, then reversed course in 2018, keeping the brand but discontinuing its sport yacht and yacht models and refocusing it on boats roughly 40 feet and under, including outboard models. For used buyers, it means the larger Sea Rays are now all brokerage boats, and Mercury engines with joystick and digital controls tie the newer ones closely to Brunswick's service network.

Sundancer generations, from 26 to 50 feet

Sundancer is Sea Ray's name for its express cruisers: a single-level cockpit over a cabin with a forward berth, a mid-berth, a galley and a head. It became the default American weekend cruiser, and we cover thirteen of them. Sea Ray often reused a number for a later, unrelated hull, so always match the model year to the right generation before comparing prices.

The small Sundancers are entry cruisers on sterndrives. The Sea Ray 260 Sundancer (from 1999) and the Sea Ray 280 Sundancer (2001 to 2009, then a narrower 2010 to 2017 redesign) suit couples on lakes and bays. The Sea Ray 300 Sundancer ran in three spells, ending in 2007, when the Sea Ray 310 Sundancer took its slot; the 310 itself had three versions between 1998 and about 2017. Today's Sea Ray Sundancer 320, launched in 2017 with sterndrives or twin outboards, is the current entry cabin boat.

In the middle, the Sea Ray 340 Sundancer was rebuilt twice before the Sea Ray Sundancer 350 replaced it in 2008, debuting Axius joystick sterndrives; the 350 and 350 Coupe have since left the range. The Sea Ray 380 Sundancer (1999 to 2004) moved up to a 13 foot beam and offered Caterpillar diesel V-drives. The current Sea Ray Sundancer 370, launched for 2021 on triple Verado outboards with a sterndrive version from 2023, is the largest Sundancer in the current range.

The big express boats are all brokerage purchases. The Sea Ray 420 Sundancer (2003 to 2005) offered gas or Cummins diesel V-drives, and the Sea Ray 450 Sundancer name covers a 1990s diesel boat and a 2010 to 2016 model with Axius or Zeus pods. The Sea Ray 470 Sundancer, sold as the 43 Sundancer for 2009 and renamed under Sea Ray's honesty-in-sizing policy, ran to 2016. At the top, the Sea Ray 500 Sundancer spans a 1990s diesel classic, a 2003 to 2005 boat and a 2010 to 2012 Zeus model.

Day boats, a fishing express and the Sedan Bridge yachts

Sea Ray's open boats are just as common. The Sea Ray SPX 210 Outboard, launched for 2015 and reimagined around 2024, is the entry-level bowrider. The Sea Ray 240 Sundeck was the brand's deck boat from 1995 to 2016, and the Sea Ray SDX 270, the renamed 270 Sundeck, carried the idea on from 2016 with a keel-up redesign and a Surf version in 2024. The Sea Ray SLX 400, Boating's Boat of the Year in 2017, is the modern flagship bowrider with sterndrives or triple outboards. The Sea Ray 290 Amberjack (2000 to 2009) was the fish-and-cruise option, with vented chines, a mid-sleeper and 230 gallons of fuel.

Before 2018 Sea Ray also built flybridge sedans. The Sea Ray 480 Sedan Bridge (1998 to 2004) has three staterooms and big Detroit, Caterpillar or Cummins diesels, while the smaller Sea Ray 44 Sedan Bridge (2006 to 2009) runs twin Cummins QSC V-drives with two staterooms before the 450 Sedan Bridge replaced it. Both are a lot of yacht for the money if the diesels check out.

Buying a used Sea Ray

Sea Rays depreciate faster than boutique brands but sell easily because so many buyers know them. The trick is condition. Sterndrive models in particular need careful attention, and boats from fresh water usually fetch more than those from salt.

Few brands match Sea Ray's dealer density, which is valuable for service and parts.

• On sterndrive Sundancers, day boats and the 290 Amberjack, inspect bellows, gimbal bearings, outdrives and exhaust risers.
• Check for wet core in decks and transoms, a known issue on some older models.
• On Axius and Zeus boats such as the 350, 450, 470 and late 500 Sundancers, review drive service records.
• On the 480 and 44 Sedan Bridge and diesel Sundancers, review diesel history and generator hours.
• Test air conditioning, generator and windlass under load.
