The GS 50 was the best boat Gulfstar ever built and also the most popular, with 172 hulls launched during a six-year production run that ended in 1980. Designed by Lazzara, the GS 50 boasts superior interior joinery, generous accommodations, robust construction, and a well proportioned hull and rig. These days it is one of the best values on the brokerage market in a larger center-cockpit boat.

The hull is stiffened, not with liners, but with full bulkheads and furniture components that are tabbed in place. The full-length rudder skeg is also bolted in place. The ballast, which consists of lead chunks embedded in concrete slurry, is encapsulated within the long fin keel.

 The master stateroom aft with an en suite head and separate shower boasts an enormous U-shaped double berth with enough space for a couple to sleep together athwartship while in harbor or separately in lateral positions while at sea. The forward stateroom, which shares a head with the saloon, has a large V-berth that fills in to form a double. The L-shaped galley runs down the walk-through alley under the center cockpit to port, with twin sinks close enough to the centerline to drain on either tack. The saloon has a dinette to port and a settee plus a pilot berth to starboard. In the two-stateroom layout, which is more appropriate for a cruising couple entertaining occasional guests.  

In a seaway the GS 50 is very well mannered. Its forefoot has enough bite and its bilges are deep enough that it does not slam much in a chop. It is relatively narrow with a moderate hull form and does not gripe when sailing to weather. All tanks are below the floorboards, which keeps the center of gravity low, sweetens the motion, and also creates extra storage space under berths and settees.

The GS 50 is not exactly a slouch when it comes to speed, though it does like moderate to heavy weather better than the light stuff. It’s not hard to keep the boat moving at 7 knots or better under working sail if the wind is blowing over 12 knots; below that you’ll need to break out spinnakers and mizzen staysails to maintain good speed.

Raised in a boating family in Newport Beach, California, Dave has been sailing and boating since his parents first pushed him off the beach in his Naples Sabot at age six. Since then, he has been a competitive sailor and boating enthusiast for more than 40 years.

Dave’s sailing accomplishments include multiple PHRF Championships on both coasts as helmsman and tactician, Etchell’s fleet championships on both coasts as tactician, as well as 10 Transpacs and Pacific Cups and more than 20 long-distance races to various ports in Mexico.

He sails frequently as tactician on a Mexican and a S. California Farr 40, manages and does tactics on a TP52 for a Mexican owner, and drives and does tactics on an RP 50 in San Diego. Dave is also active in both the Viper Fleet and F18's from time to time. While Dave has raced sailboats most of his life, he didn’t begin working in the marine industry full-time until he landed the sales and marketing manager position with the world’s premiere sailboat design house, Farr Yacht Design.

After a time there, he moved back to the West Coast and became the general manager for the world’s third-largest Sea Ray dealer in Newport Beach, Newport Boats. They were also the Meridian, Atlantis, Polar Fishing Boats, and Azimut dealership. Dave distinguished himself by running their most profitable store and maintaining a CSI score of a perfect 10 for the last 14 months of his employment.

The downturn of 2009 ended his tenure there, as most of the staff was laid off. He ultimately moved to another local broker, Long Beach Yacht Sales, and quickly became the company’s top salesman. Dave was also awarded Salesperson of the Year in 2010 for dollar volume and was second in units sold. Toward the end of 2011, Dave joined the Denison Yachting team in our Marina del Rey, California location, where he has quickly added many quality listings around the US and the world.

In 2012, he opened the Newport Beach, California office for Denison Yachting and continued to be their top seller in the area. In 2019, he opened Denison’s second San Diego location. He now travels the world extensively selling yachts on every corner and has logged well over 350,000 miles navigating the world’s oceans. He is ready to help you realize your boating dreams, either power or sail.
