Granfort 370 GTX
vs Regal 33 XO
Two outboard express cruisers at different price points and with very different propositions. One is America's most-recognized name in this segment. The other brings a wider platform, a 10-year structural warranty, and 50 mph published sea-trial performance — all at a competitive entry price.
Granfort 370 GTX
Regal 33 XO Competitor Class
Before choosing between these two boats,
understand the real decision.
This guide is written for buyers who are already aware of Regal's reputation and want to know whether the Granfort 370 GTX deserves serious first-choice consideration. The Regal 33 XO is a well-known 34-foot outboard express cruiser with a strong U.S. dealer network, a recognizable brand, an UltraLounge cockpit feature, and a Lifetime Limited Hull Warranty on certain structural components. The Granfort 370 GTX answers with a measurably wider 11'6″ beam, published 50 mph sea-trial performance, a 10-year structural warranty covering both hull and deck, ABYC and U.S. Coast Guard compliance, and Fibrafort's manufacturing depth — all starting at $439,900 with options to build well beyond.
"The single most important number is not speed. It's 10 years. Granfort's structural warranty covering both hull and deck reframes the entire ownership comparison."
The Regal 33 XO is a legitimate American express cruiser with a polished cockpit, UltraLounge seating, a mid-cabin with convertible queen or twin configuration, a galley with two-burner stove, and the hardtop or PowerTower as popular upgrades. It is a comfortable, mid-range weekender with wide U.S. availability. MSRP references have been published around $477,000 for well-equipped configurations.
The Granfort 370 GTX is an open sport cruiser engineered around social movement, water connection, and functional luxury. The open bow, expansive cockpit, social stern, and 4-person overnight cabin make it more than a dayboat while keeping the energy of an open performance cruiser — backed by a 10-year structural warranty that Regal's standard hull coverage cannot match.

Wider, Lighter, Faster in Published Data — and Backed by Deeper Structural Coverage.
Granfort's argument is not one feature in isolation. It is the combination of a wider 11'6″ beam — 14 inches wider than the Regal — a published 50 mph sea-trial result, 14-person day capacity, four-person overnight capability, 222 gallons of fuel versus Regal's 150 gallons, and a 10-year structural warranty covering both hull and deck.
The 370 GTX also carries a more open social personality. The cockpit is built for movement and connection. The aft zone creates a balcony feeling over the swim platform. The grill table, bar-style interaction, convertible stern lounge, and dry shower support true weekend use that goes well beyond a dayboat.

Brand Recognition, Dealer Access, and a Well-Proven Cockpit Design.
The Regal 33 XO is a credible, well-reviewed boat with a strong base of existing owners. It is sold through a wide U.S. dealer network, making sea trials, service, and parts access straightforward for buyers in most states. The UltraLounge — a motorized seat that slides 11 inches to extend cockpit space — is a genuinely clever feature, and the optional Hardtop or PowerTower are well-executed additions.
The mid-cabin with convertible queen/twin configuration, dedicated head with shower, and two-burner galley provide solid overnight capability. Regal publishes a Lifetime Limited Hull Warranty, which is a marketing strength — though buyers should read the specific scope and exclusions carefully before comparing it directly to Granfort's 10-year structural hull-and-deck coverage.

Use Published Numbers Carefully — and Confirm the Exact Unit Before Signing.
The Granfort 370 GTX has a published manufacturer sea-trial result showing 51.1 mph with 7 persons aboard (twin Mercury VERADO V10 · 2×400 HP · Prop Pitch 19), 8.94 seconds to plane, and approximately 33–35 GPH at cruise. Best range published at 209 miles with a 7-person load. These are the clearest published performance numbers in this comparison.
For the Regal 33 XO, published references vary by engine configuration and source. With twin 300 HP engines, performance reviews reference speeds in the 45–50 mph range at wide-open throttle, with cruise fuel burn in the mid-20s GPH. Regal offers configurations from twin 250 HP through twin 300+ HP, and performance changes meaningfully across those options.

The Warranty Is the Builder's Confidence Statement. Compare Scope, Not Just the Headline.
Both boats offer headline warranty language that sounds strong. Buyers need to read the fine print on what is actually covered, for how long, and under what conditions before treating warranty language as equal.
Granfort 370 GTX · 10-Year Structural
Hull + deck structural coverage published by Granfort. ABYC + U.S. Coast Guard compliance referenced in Granfort materials. The scope includes both hull and deck in a single 10-year structural warranty — a scope that goes beyond what most competitors in this class publish.
Verify final warranty document with dealer before purchase.
Regal 33 XO · Lifetime Limited Hull
Regal publishes a Lifetime Limited Hull Warranty, which is a strong marketing claim. The word "limited" is the key qualifier — buyers should request the full warranty terms to understand exactly what structural components are covered, what conditions void the warranty, and how claims are handled. "Lifetime" for the original owner often differs significantly from "lifetime" in a resale scenario.
Request and read the full warranty document before signing.
"For buyers who plan to own the boat for more than five seasons, Granfort's 10-year structural hull + deck coverage is the single strongest ownership-confidence argument in this comparison."
Granfort Is a Discovery Brand in the U.S. — But It Is Not Backed by a Beginner Factory.
The buyer's hidden objection is simple: "I know Regal. Why should I trust Granfort?" The answer starts with Fibrafort — the manufacturer behind the Granfort name in Brazil, with over three decades of documented production history and an international export footprint covering more than 40 countries.
Porsche Newsroom reported that Fibrafort worked with Porsche Consulting to restructure and improve operational processes — covering how boats are developed, planned, produced, and delivered. That manufacturing discipline rarely shows up in a brochure, but buyers feel it in consistency and long-term ownership experience. The honest framing: this is Porsche Consulting-advised production processes — not "Porsche-designed" boats. The distinction matters, and Granfort is transparent about it.
Use These Six Filters Before Choosing Either Boat.
Warranty Scope
Compare duration and covered structure. Granfort's 10-year hull + deck structural claim is materially different from Regal's Lifetime Limited Hull. Read both documents in full.
Certification Documents
Ask for written ABYC, U.S. Coast Guard, NMMA, or other applicable compliance documentation for the exact boat. Do not rely on marketing language alone.
Performance Proof
Compare sea-trial data, not opinions. Match engines, load, fuel level, propellers, bottom condition, and sea conditions for a valid comparison.
Mission Fit
Choose Regal for brand familiarity and a tighter, feature-rich cockpit. Choose Granfort for open sport-cruiser energy, wider beam, higher max power, and greater fuel range.
Beam and Platform
Granfort's 14-inch beam advantage is the largest single dimensional difference in this comparison. Walk both boats and feel the difference in cockpit circulation.
Support After Purchase
Regal has broader domestic dealer coverage. Granfort is growing in key U.S. coastal markets. Confirm service access, parts lead times, and warranty-claim process before final payment.
Familiar American Comfort — or Open Sport-Cruiser Connection?
Regal's lifestyle is polished and familiar. The UltraLounge, optional Hardtop, galley, dedicated head, and mid-cabin create a comfortable, recognizable weekender profile. Buyers who've spent time on American express cruisers will feel at home immediately.
Granfort's lifestyle is more open, social, and water-connected. The cockpit, stern, bow, and cabin work together to support day boating, coastal runs, entertaining, and overnight stays without losing the energy of an open performance boat. The grill table, convertible stern lounge, social stern balcony feel, and dry shower support real weekend living — not just daysailing with a cabin attached.
The 370 GTX's cockpit is built for social movement — not just seating.
Functional Luxury Is Where Granfort Becomes More Than a Comparison Number.
Specs help buyers compare. Experience closes the decision. Granfort's strongest emotional advantages are the open cockpit, aft balcony feeling, social stern, grill-table atmosphere, convertible lounge, dry shower, and the feeling that the boat is made for both movement and relaxation — not just a checked-box list of overnight features.
This is why Granfort should not be positioned only as a lower-risk or better-warranty option against Regal. It should be understood as a first-choice sport cruiser for buyers who want performance, style, social space, manufacturing credibility, and a more connected boating lifestyle — one that happens to also carry the strongest structural warranty in the comparison.
Cockpit
Built for movement, not just seating. Wide circulation, grill table, convertible stern lounge.
Bow
Full open bow for four — designed for tranquility and connection, not just forward seating.
Stern
Aft balcony feeling with twin 400 HP outboards and ample swim platform circulation.
Cabin
4-person overnight · dry shower · galley · designed for actual use, not just specification compliance.
