Seller's Comments:

We owned a 1999 Nordic Tug from 2012 to April 2024. We loved that boat. I did all of my own maintenance on the boat, and implemented many major upgrades throughout those years. In 2017 we retired early (me age 54) so we could spend the winters in the FL Keys and Bahamas. By 2024 we felt we thought we were ready to get out of boating and sold the Nordic Tug "Knot Workin" in April 2024.

"After a year, we really missed spending winters in the FL Keys, and came up with a plan to buy a boat and keep it in FL so we would not need to travel the Atlantic ICW from Baltimore MD each winter. We went on a 19 day search in the summer of 2025 looking for a boat. I wanted twin diesels, and really wanted to try a fast powerboat. After looking at boats as far as Key West FL, we ended up buying the Sea Ray 400 EC in North Myrtle Beach SC. What a different experience with the Sea Ray traveling down the ICW! With the 8' bridge clearance, we only needed two bridges opened for us the entire way, and with the speed of the boat, we made it to Marathon FL in record time. In SC I outfitted the boat with the best and largest anchor that would fit (Rocna), and sufficient chain rode for all anchoring conditions. I also reconfigured the house battery system to use a 12V LiFePO4 battery to supply power to the entire cabin and the DC refrigerator so we could live on the boat on a mooring for 6 months comfortably. It was a dramatically different experience in the FL Keys being able to get to fishing and snorkeling locations in 1/3 the time it would take with our 9 knot Nordic Tug. We had a great time on the boat in the FL Keys the winter of 2025/2026, but our plans for future winters were derailed. As a result, we put the boat up for sale and brought it up the ICW to Annapolis".

Fuel Burn:

I measured 15 to 20 gph (total) traveling 847 mi down the AICW (a mix of idle speed and planning). Expect ~28 gph total fuel consumption when planning at 28 mph / 24 knots. Oil sample reports for the port engine taken 27 February 2024 and starboard engine taken 25 March 2025, and both engines 30 Apr 2026 verify the good condition of the engines. These reports are available upon request.

Upgraded in 2025 to be comfortable and functional at anchor / mooring for weeks. The two stateroom layout and single bathroom with separate shower make her ideal for extended cruising or entertaining. The water and holding tanks easily support a couple for a week (daily showers) before the need to visit a fuel dock. The settee area pulls out to sleep additional guests.

The 8 kW diesel generator with low hours powers the forward and main salon separate HVAC units (air conditioning and/or heat), as well as the water heater, stove, microwave, oven/broiler/air fryer, and refrigerator.

All salon DC powered items (LED lights, USB outlets, water pump, head, etc.) including the refrigerator / freezer are powered by a 320 Ah LiFEPO4 (lithium) battery installed 2025. The high capacity of the battery permits up to 48 hours of DC operation before the need to charge the battery with the generator or shore power. Daily charging of only 2.5 by generator is sufficient for long term off-grid living.

Anchor in confidence anywhere in the Atlantic Intracoastal Waterway (AICW), Florida Keys, Bahamas, Caribbean. The anchor and rode was upgraded in 2025 to a Rocna Mk II 25 (55 lb) galvanized (one size larger than recommended for the boat), and a rode consisting of 150 ft of 5/16" HT / G4 galvanized chain spliced to 100 ft of 5/8" nylon rope. The Lofrans Progress.1 windlass confidently deploys and retrieves the anchor and rode. A chain locker stores the rope and chain.

A new inflatable tender and outboard confidently transports 3+1 people from boat to shore. The 17" inflation tubes keep everyone dry during high wind conditions. The tender stores in a simple davit on the aft of the Sea Ray.

Helm navigation electronics include 2x Garmin chart plotters, sonar (fish finder), and radar. Everything you need to safely travel day or night.

* The recent professional survey conducted 15 August 2025 verifies the excellent condition of this boat. Oil analysis verifies the condition of the diesels.

Manufacturer Notes:

With a fresh Euro-look, the Sea Ray 400 Express Cruiser is one stylish sport yacht. Its design evolution is the result of listening to sport yacht owners, then incorporating their ideas into the 400 Express Cruiser. The 400 Express Cruiser presents a sleek deck with extensive use of stainless steel in all external fittings, including the bow rail and deck runners. Powered by twin Cat 3116 /350 hp diesel inboards, the Sea Ray 400 Express Cruiser extends trips with its 300-gallon fuel capacity. Adjustable double helm and companion seats face a burl instrument panel. The curved tri-section tinted glass windshield with electric front vent allows better viewing and increased air flow. The fiberglass sport spoiler provides room for mounting electronic equipment. A refreshment center with wet bar, sink, cooler, and icemaker is conveniently located in the cockpit beside the aft-facing portside cockpit seat. To starboard, the U-shaped aft bench seating with hi - lo table can be converted to a sunpad. Swimmers and divers can come aboard easily thanks to the fold-down stainless steel swim ladder. A hot and cold transom shower is conveniently located at the wide swim platform. Integral fender storage keeps the transom area tidy. In the salon, a granite-look fiberglass table converts the sofa to a dining area. Passengers may relax on the sofa and enjoy the entertainment center.
