Granfort 370 GTX vs Hurricane SunDeck 3200 OB What buyers need to know.
The Hurricane SunDeck 3200 OB is a genuinely impressive deck boat — 32 ft, hardtop standard, 6'3" cabin headroom, standard dual 12" Simrad displays, JL Audio, 248-gallon fuel, and a Boating Magazine-confirmed 51.5 mph with twin 400 HP V10s at $385K–$450K. The Granfort 370 GTX is a different kind of boat: a 37-foot dedicated sport cruiser, 5 feet longer, ABYC and U.S. Coast Guard certified, backed by Porsche Consulting-advised production process improvements, and backed by a 10-year structural warranty covering hull and deck.

Book a sea trialImportant category distinction: The Hurricane SunDeck 3200 OB is a deck boat — engineered and marketed as "the ultimate dayboat." It is designed primarily for large-group day use with overnight capability as a secondary feature. The Granfort 370 GTX is a dedicated 37-foot sport cruiser with overnight comfort, cabin, galley, and enclosed head as primary design pillars. Buyers who want the deck boat social experience should choose the Hurricane. Buyers who want a full-capability sport cruiser with overnight utility, stronger certification, and deeper warranty confidence should choose Granfort.
Before choosing between these two boats, understand what category each one is actually built for.
Buyers comparing the Granfort 370 GTX and the Hurricane SunDeck 3200 OB are evaluating two boats with genuinely different missions — one maximised for open-deck social entertaining, one purpose-built for sport cruising and overnight capability.
The Hurricane SunDeck 3200 OB is Hurricane's most ambitious boat — a 32-foot flagship stepping well outside the brand's traditional deck-boat roots. Boating Magazine called it "envisioned as the ultimate dayboat" and praised its exceptional room for entertaining and lounging. The independently published test confirmed 51.5 mph with twin 400 HP V10 Mercury outboards, 18.5 GPH combined at 31 mph cruise, and 7 seconds to plane. It is one of the most feature-complete deck boats at its price point.
The Granfort 370 GTX is a 37-foot dedicated sport cruiser — 5 feet longer, ABYC and U.S. Coast Guard certified by published brochure, built with Porsche Consulting-advised production process, backed by a 10-year structural warranty covering hull AND deck, and starting from $439,900. Its overnight mission — 14 day / 4 night published capacity with cabin, galley, and enclosed head — is primary, not an option.
Simple buying question: do you want the ultimate deck boat for open-air entertaining and large groups — or a dedicated 37-foot sport cruiser with overnight capability, a deeper warranty, and stronger long-term confidence?
Fibrafort — South America's largest boat manufacturer. 35 years. 18,000+ boats. 44 countries.
Granfort is the U.S. export brand of Fibrafort — the largest boat manufacturer in South America by units produced. Understanding the factory behind the name is part of understanding what gives the Granfort its ownership confidence story.
Fibrafort was founded in Brazil in 1990 and has built over 18,000 boats across more than three decades, exporting to customers in 44 countries. It is not a boutique builder. It is a high-volume, internationally certified manufacturer with a decades-long track record. The Granfort 370 GTX is built in that factory — to ABYC and U.S. Coast Guard standards, with Porsche Consulting's process engineering embedded in the production system.
Porsche Consulting-advised production processes. Measurable results. No other builder in this class can say this.
Fibrafort — the manufacturer behind Granfort — engaged Porsche Consulting not to style a boat or attach a luxury name to the product, but to improve how its boats are developed, planned, produced, and delivered. The work focused on operational excellence: development processes, production flow, logistics, material and cost planning, purchasing, storage, and lean manufacturing practices.
The results were published and measurable: material costs reduced by 10%, extra daily parts orders cut by 90%, reject rate reduced from 28 items to 19, and overtime reduced by 48%. For Granfort buyers, this means the brand is backed not just by design and performance, but by a manufacturing culture shaped by lean thinking, process discipline, quality improvement, and continuous operational refinement.
5 feet longer. A full cabin. Certified, warranted, and purpose-built to cruise.
The Hurricane SunDeck 3200 OB is 32 ft LOA. The Granfort 370 GTX is 37 ft — 5 feet more boat on the water. That length advantage translates directly into more overnight space, a larger cockpit, a more planted feel in following seas, and a boat that reads as a genuine cruiser rather than an oversized day boat.
The Granfort's cabin, galley, and enclosed head are primary features — designed for the overnight mission, not retrofitted as an afterthought. With 14-day and 4-night published capacity, it is a boat you can leave the dock on Friday evening and return Sunday confident — not just capable.
On certification and warranty: Granfort publishes ABYC and U.S. Coast Guard compliance in its brochure and backs the hull AND deck with a 10-year structural warranty from day one. These are specific, published, verifiable claims that Hurricane's documentation does not match at the same level of specificity.
Hardtop standard. 51.5 mph confirmed. And more standard equipment than almost anyone at the price.
Hurricane has been building deck boats for over 50 years, and the SunDeck 3200 OB represents the brand's most ambitious step yet — a 32-foot wide-beam deck boat designed to compete with cabin cruisers while keeping the open-deck social identity that makes Hurricane boats recognisable.
The standard equipment list is genuinely impressive: dual 12" Simrad NSX displays, JL Audio Ultimate Sound System, hardtop with power arch and 6-foot aft power shade, 32" SMART TV in the cabin, microwave, refrigerator, windlass, and aft-facing seat at the transom. Boating Magazine tested it and confirmed 51.5 mph with twin 400 HP V10 Mercury outboards — the fastest top speed in this comparison. The 6'3" cabin headroom is class-leading.
Boating Industry named the SunDeck 3200 a 2025 Top Product. At $385,000 base and approximately $450,000 well-optioned, it also comes in below Granfort's starting price — making it an attractive entry point for buyers whose priority is the deck boat experience.
Head-to-head test results — both boats, named sources.
The Hurricane SunDeck 3200 OB has been independently tested by both boats.com and Boating Magazine — two of the most credible U.S. marine publications. The Granfort sea trial was published on granfortboats.us in April 2025. These are the three clearest published data points for this comparison.
What the data tells you: On identical engines (twin 400 HP V10), the Hurricane reaches 51.5 mph versus Granfort's 50 mph — a 1.5 mph difference that is within normal test variation. The Hurricane burns 18.5 GPH at a 31 mph cruise. Granfort burns approximately 13.2 GPH at cruise — 40% more fuel efficient per hour. The Hurricane's 1,500 lb weight penalty versus Granfort explains the efficiency gap. Both planes in approximately 7 seconds; the Hurricane takes 12.2 seconds to reach 30 mph under full load — Granfort reaches 29 mph in 6.8 seconds under its test conditions.
Hurricane's open-deck social energy. Or Granfort's 37-foot coastal cruising identity?
Hurricane's lifestyle is built around the deck boat experience at its finest: maximum open seating, large groups, sun worshippers on the bow triple sunbed, social action from stern to bow, and a boat that feels like a party venue as much as a vessel. The 5'6" freeboard creates a deep, secure cockpit — Boating Magazine specifically called it excellent for families with small children. For buyers who measure a great day by how many people were aboard and how loud the JL Audio was — Hurricane is the answer.
Granfort's lifestyle is fundamentally different: it is built for the run and the destination equally. The 37-foot hull, open cockpit, wide beam, and cabin beneath give the boat a purposeful cruising identity. A fast morning run, an afternoon at anchor, a proper meal in the cabin, four people sleeping comfortably aboard — this is what the Granfort is designed to do as primary use, not as an available option. For buyers who want to cover coastal distance, explore anchorages, and actually live aboard for the weekend — Granfort is the better match.
The warranty is the builder's confidence statement. Read both carefully.
Hurricane is a well-established American manufacturer with a 50-year history and a strong dealer network. Its warranty terms should be confirmed with the selling dealer. Granfort's 10-year structural warranty covering hull AND deck is a published, specific, on-record claim from day one — the broadest structural coverage statement in this comparison. For a boat you plan to own for a decade, the difference in scope and duration is material to your long-term ownership confidence.
Hurricane's open deck entertainment platform. Or Granfort's wider 5-foot-longer social cruiser?
The Hurricane SunDeck 3200 OB's social layout is exceptional for its category. The bow triple sunbed seats three side by side. The helm seats swivel aft for social engagement at anchor. The aft platform is wide enough to board from both sides. The galley entertainment centre with refrigerator, optional grill, and pressurised sink creates a genuine party infrastructure. For large groups — eight, ten, twelve people — the Hurricane's open deck is the more social environment.
The Granfort's social answer is flow and depth. The 37 ft hull with 11ft 6in beam gives the cockpit more physical volume than the Hurricane's 32 ft platform. The open bow, wide stern, and sport-cruiser feel create a connected, active environment — and when the party ends and the sun goes down, four people can sleep aboard in comfort and wake up ready for the next day's run. The Hurricane can do that too — but it is not the Hurricane's primary design intent. It is Granfort's entire identity.
Granfort 370 GTX vs Hurricane SunDeck 3200 OB — every number that matters.
Hurricane wins on top speed (51.5 mph tested), cabin headroom (6'3"), standard equipment value, HP ceiling (1,000 HP), fuel capacity, and deck boat social space. Granfort wins on LOA (5 ft longer), beam, weight efficiency, warranty scope, certification specificity, overnight mission depth, and price-to-cruiser-class value.
| Category | Granfort 370 GTX | Hurricane SunDeck 3200 OB | Buyer meaning |
|---|---|---|---|
| Boat category | Dedicated 37 ft sport cruiser · overnight primary | Deck boat · ultimate dayboat · overnight secondary | Different missions. Buy the boat whose category matches your actual primary use. |
| Starting price | $439,900 (granfortboats.us published) | ~$385,000 base MSRP · ~$450,000 well-optioned (boats.com) | Hurricane enters below Granfort. Both boats exceed $400K well equipped — but are in different categories. Price comparison matters less than mission match. |
| LOA | 37 ft (11.28 m) | 32 ft (9.75 m) | Granfort is 5 feet longer — directly felt in cockpit volume, overnight space, sea-keeping behaviour, and coastal cruising identity. |
| Beam | 11 ft 6 in (3.51 m) | 10 ft 6 in (3.20 m) · published | Granfort is 12 inches wider — an important difference in cockpit physical space and lateral stability at anchor. |
| Draft | 2.2 ft (26 in) engines raised | Not prominently published — outboard with similar shallow-water capability | Both are outboard boats with good shallow-water access. Granfort publishes a specific draft figure. |
| Published weight | 13,500 lb with engines | ~15,000 lb (boats.com · BoatTEST) | Granfort is approximately 1,500 lb lighter even with engines fully rigged — contributing to its fuel efficiency advantage at equivalent cruise speeds. |
| Top speed (tested) | 50 mph (published sea trial · twin 400 HP) | 51.5 mph (boats.com · twin 400 HP V10 · full fuel · 5 people) | Hurricane is 1.5 mph faster in published testing on equivalent engines — a marginal difference within normal test variation. Both are fast boats. |
| Max HP | 800 HP (2×400 HP std) | 1,000 HP · factory-installed twin configuration (Hurricane published) | Hurricane has a 200 HP higher ceiling. At max 1,000 HP, Hurricane reaches just under 55 mph (Polaris/Hurricane published). |
| 0 to plane | 7.5 seconds (Granfort sea trial) | ~7 seconds (boats.com · full fuel · 5 people) | Essentially equal — both planes in approximately 7 seconds. Granfort's lighter hull reaches 29 mph in 6.8 s; Hurricane reaches 30 mph in 12.2 s under heavier test conditions. |
| Cruise fuel burn | ~13.2 GPH (Granfort sea trial) | 18.5 GPH at 31 mph (boats.com confirmed) | Granfort burns approximately 40% less fuel per hour at cruise. Over a full season of regular use, this gap represents significant operating cost savings. |
| Fuel capacity | 222 gal | 248 gal · published | Hurricane carries 26 more gallons. Granfort's lower burn rate per hour partially offsets this on range per departure. |
| Fresh water | 38 gal | 30 gal · published | Granfort carries 8 more gallons of fresh water — a modest overnight advantage. |
| Deadrise | 18° | 19° (Boatmart confirmed) | Hurricane's 1° deeper V is a marginal rough-water advantage. A Hurricane technician drove the 3200 in 3+ foot Lake Michigan chop at 45 mph and reported it handled well. |
| Cabin headroom | 6 ft 0 in | 6 ft 3 in · published / confirmed Boating Magazine | Hurricane has 3 inches more headroom below — a real comfort advantage for taller users spending time in the cabin. |
| Hardtop | Open (bimini optional) | Standard hardtop with power arch and 6 ft aft power shade · Hurricane published | Hurricane's hardtop and power shade give daily weather protection and UV coverage that the open Granfort does not offer by default. For Florida and Gulf Coast buyers, this has genuine daily-use value. |
| Standard electronics | Mercury VesselView · joystick std | Dual 12 in Simrad NSX · JL Audio Ultimate · 32 in cabin TV · wireless charger (Hurricane published / Boating Magazine confirmed) | Hurricane's standard electronics package is among the best at the price point. Boating Magazine noted the dual 12 in Simrads and JL Audio as standout features. |
| Overnight capacity | 14 day / 4 night · Granfort published | Cabin converts to daybed · occasional overnight supported | Granfort publishes specific overnight capacity. Hurricane's cabin is a genuine overnight space but is not the boat's primary design intent. |
| Structural warranty | 10-year structural hull + deck · published brochure | Confirm terms with dealer · Hurricane is a 50-year American manufacturer | Granfort's 10-year structural warranty covering hull AND deck is specifically published. Hurricane's terms should be confirmed in writing before purchase. |
| Certification | ABYC + U.S. Coast Guard · published in brochure | American-built (Elkhart, Indiana) · NMMA context · verify unit documentation | Granfort publishes ABYC and USCG compliance as a specific brochure claim. Hurricane is American-built to U.S. standards — verify certification documents at purchase. |
| Manufacturing pedigree | Porsche Consulting-advised production processes · published | Hurricane Boats · Polaris brand · 50+ years deck boat heritage | Hurricane's heritage is genuine and well-earned. Granfort's Porsche Consulting story is the differentiator no competitor at any price in this segment can match. |
Six criteria that define a smart decision in this class.
Before committing to a boat at this price point, work through these six factors. This comparison addresses each one directly with verified data.
Safety & certification
Granfort publishes ABYC + U.S. Coast Guard certification in its brochure — the clearest documentation for American buyers covering insurance, financing, and resale. Hurricane is American-built in Elkhart, Indiana — also to U.S. standards. Granfort's specific published statement requires no follow-up confirmation.
Structural warranty
Granfort leads with a 10-year structural warranty on hull and deck from day one — specifically published. Hurricane's warranty terms should be confirmed with the selling dealer. For a $400K+ purchase you plan to own for a decade, getting both warranties in writing side by side before signing is essential.
Category match
The most important criterion in this specific comparison. Hurricane SunDeck 3200 OB is a deck boat — "the ultimate dayboat" (Boating Magazine). Granfort 370 GTX is a 37-foot sport cruiser with overnight as its primary mission. Buy the boat whose category matches how you actually use your boat most of the time.
Weight and fuel efficiency
Hurricane weighs ~15,000 lb. Granfort weighs 13,500 lb with engines. On identical twin 400 HP V10 engines, Hurricane burns 18.5 GPH at 31 mph cruise. Granfort burns ~13.2 GPH — approximately 40% less per hour. Over a full season of regular use, that gap is thousands of dollars in fuel savings.
Construction technology
Granfort uses Divinycell closed-cell PVC foam core in hull and deck — aerospace and wind-energy grade structural material that adds stiffness, reduces weight, and eliminates water absorption permanently. Hurricane uses fiberglass deep-V construction. The foam core contributes directly to Granfort's 1,500 lb weight advantage over the Hurricane.
LOA and overnight utility
At 37 ft, Granfort is 5 feet longer than the Hurricane's 32 ft platform — and that length is in service of the overnight cruising mission. Cabin, galley, enclosed head, and 4-night capacity are primary features on the Granfort, not secondary ones. If overnight stays and weekend cruising are part of your actual use, Granfort delivers materially more of what you need.
Choose based on your actual mission — not first impressions at the dock.
Choose the Hurricane SunDeck 3200 OB if you prioritise:
- The ultimate deck boat social experience — maximum open seating for large groups

- Standard hardtop with power arch and 6 ft aft power shade — daily UV and weather protection
- Standard dual 12" Simrad NSX, JL Audio, 32" cabin TV, windlass — exceptional standard kit
- A lower entry price — ~$385K base vs Granfort's $439,900
- American-built boat from a 50-year heritage brand (Hurricane / Polaris)
Choose the Granfort 370 GTX if you prioritise:
- A dedicated 37-foot sport cruiser — 5 feet more boat than the Hurricane
- Overnight as a primary mission — cabin, galley, enclosed head, 4-night capacity built in
- 12 inches wider beam — more cockpit volume and lateral stability
- 40% better fuel efficiency at cruise — ~13.2 GPH vs Hurricane's 18.5 GPH
- 10-year structural warranty covering hull AND deck — from day one, published
- ABYC + U.S. Coast Guard certification — published in the brochure, specific and verifiable
- Porsche Consulting-advised manufacturing pedigree — no competitor in this segment can match it
- A sport cruiser identity that rewards the journey as much as the destination
Hurricane wins the deck boat category. Granfort wins the sport cruiser decision.
The Hurricane SunDeck 3200 OB is a genuinely excellent boat that fully earns its 2025 Top Product recognition. Its standard equipment list, tested 51.5 mph performance, 6'3" cabin headroom, hardtop, and social layout make it one of the most impressive deck boats available at any price. For buyers whose primary use is large-group day boating, sandbar entertaining, or casual family outings — the Hurricane SunDeck 3200 is the right answer.
The Granfort 370 GTX wins the sport cruiser comparison. It is 5 feet longer, 12 inches wider, 1,500 lb lighter, burns 40% less fuel at cruise, is ABYC and U.S. Coast Guard certified by published brochure, backed by a 10-year structural warranty covering hull AND deck from day one, and built with Porsche Consulting-advised production processes. For buyers whose mission is coastal cruising, weekend overnight trips, and long-term confidence in the boat they own — Granfort delivers more of what matters.
The real question is not "which boat is more impressive?" It is "which boat is built for how I actually plan to use it?" Deck boat entertaining — Hurricane. Sport cruiser ownership — Granfort.
