Gulfstar 47 Sailmaster Sailboats for Sale

The Sailmaster 47 carries a comfort ratio in the low forties, which puts it firmly in the comfortable offshore cruiser category. Its displacement-to-length ratio sits in moderate territory, meaning it is not a heavy slug but also not a flier — it prioritises seakeeping over speed, which suits the kind of owners who have historically chosen it. The fin keel with skeg-hung rudder is a well-proven offshore configuration that balances upwind efficiency with rudder protection. The ballast ratio is somewhat modest by bluewater standards, so the boat carries sail area conservatively and rewards a sailor who reefs early rather than drives it hard in a building breeze.

Layouts on the Used Market

The Sailmaster 47 was offered in two distinct interior arrangements, and both appear with reasonable regularity on the used market. The more common three-stateroom layout places a forward owner's cabin with en-suite head and shower, a midships cabin with upper and lower berths, and a separate aft stateroom — all connected through the raised salon amidships. This arrangement was popular with charter-minded buyers and those who expected to carry crew or guests regularly.

The two-stateroom alternative trades the midships cabin for a more generous salon, with a U-shaped dinette and additional settee seating. This layout suits couples living aboard who prioritise a more open communal space over berth count. Both versions retain the raised salon that was the design's signature feature — the wraparound seating and panoramic windows elevated the Sailmaster 47 above typical production cruisers of its era. The raised helm position in the centre cockpit provides good visibility forward and a naturally sheltered position for the watch keeper.

The sloop rig variant exists but the ketch is far more commonly encountered. The ketch configuration suited the boat's motorsailer character and gives owners practical options for sail reduction — the mizzen can be left standing while reefing the main, and the mizzen staysail adds drive in reaching conditions without complicating the headsail furler.

Equipment and Common Upgrades

Boats that have been actively cruised through the current era arrive well-equipped by any reasonable measure. Solar panels are now a nearly universal fitting, typically mounted on arch structures over the cockpit or on a custom frame aft. Air conditioning is commonly fitted — the Perkins diesel's alternator output and shore power connections have long made this practical on a boat that spends significant time in warm-water anchorages and marinas. Bow thrusters appear on many examples, a reflection of the boat's substantial displacement in tight fairways and the practical reality of single-handed docking.

Furling mains have replaced the original slab-reefing systems on a large proportion of the fleet, often paired with furling headsails that were not original equipment. Radar, autopilot, and chartplotter are standard across the market — most boats have been updated through at least one electronics generation. Biminis and dodgers are universal, typically custom-fitted and often substantial, covering the entire centre cockpit in a hard or semi-hard enclosure that transforms the boat into an all-weather passagemaking platform.

Watermakers appear on a meaningful portion of examples, particularly those that have done extended offshore passages or spent time in areas where marina water quality is unreliable. Lithium battery banks are a frequent owner upgrade on more comprehensively refitted examples, often appearing alongside upgraded solar and inverter systems. Satellite communications, including Starlink terminals, have made their way onto actively cruised boats. Teak decks — original or replacement — appear on some examples, though owners should assess their condition carefully given the maintenance burden and the potential for fastener corrosion beneath deteriorating teak.

What to Inspect

The Gulfstar Sailmaster 47 is a fibreglass boat from an era when hull quality varied considerably across the production run, and any survey should begin with a thorough assessment of the hull laminate. Osmotic blistering below the waterline is a known concern on GRP boats of this vintage, and the presence, severity, and treatment history of any blistering should be established before proceeding. Boats that have had a proper barrier coat applied after a blister treatment are in a better position than those where blistering has been cosmetically managed without underlying remediation.

The keel-to-hull joint deserves careful attention. The fin keel attachment on boats of this era can develop stress cracking and, in neglected examples, movement or weeping at the joint. A surveyor familiar with this type of construction should probe the area thoroughly.

The deck hardware and core deserve inspection. Much of the original deck hardware will have been re-bedded multiple times over the boat's life, and any locations where water has had access to balsa or foam core for extended periods may show softness or delamination. Focus particularly around chainplates, stanchion bases, and any areas where through-deck fittings have been added by subsequent owners.

The Perkins diesel that powered the original boat is a well-regarded and thoroughly documented engine, and parts remain available. However, the engine is now a very mature example, and a compression test, oil analysis, and thorough inspection of the raw water cooling system, injectors, and heat exchanger are essential. Many boats have had engine replacements at some point — verify that any replacement was properly engineered for the boat's installation and that documentation exists.

The standing rigging on a ketch of this age should be assessed against its last replacement date. Two-mast rigs carry more individual pieces of rigging than a comparable sloop, and the mizzen mast chainplates and deck fittings are sometimes less carefully attended to than the mainmast chain. Inspect both masts and their associated rigging hardware.

The raised salon windows are a distinctive and desirable feature, but their frames and seals are a known maintenance point. Check for any evidence of leaking at the window frames, which can introduce water into the raised salon structure.

Availability and Buyer's Takeaway

The Sailmaster 47 fleet is concentrated in the United States, with Florida and the Gulf Coast representing the densest concentration — reflecting both the builder's origins in St. Petersburg and the boat's natural affinity for the Caribbean cruising grounds reached from that base. Mexico's Pacific and Gulf coasts also host examples. Buyers on the US East Coast and Gulf of Mexico will encounter the most options; those on the West Coast or in Europe may face a more limited and logistically demanding search.

The Gulfstar Owners Club provides a useful network for buyers, offering access to experienced owners who can speak to common issues and the history of specific boats. Reaching out before purchase is strongly advisable.

Before committing, work through this checklist:

• Commission a survey from a surveyor experienced with GRP boats of this vintage
• Establish the full history of any osmotic blister treatment and subsequent barrier coat work
• Inspect the keel-to-hull joint for cracking, movement, or weeping
• Check deck core integrity at all chainplate locations, stanchion bases, and owner-added fittings
• Verify engine condition with compression test and oil analysis; confirm replacement provenance if applicable
• Assess both mast rigs and all standing rigging, noting replacement dates
• Examine raised salon window frames and seals for evidence of water ingress
• Review teak deck condition if fitted, including fastener integrity beneath
• Confirm watermaker, solar, battery bank, and any lithium systems have been properly integrated
• Contact the Gulfstar Owners Club and speak with current owners about the specific hull's history
