Granfort 370 GTX vs Formula 360 Crossover

/ July 3, 2026

Granfort 370 GTX vs Formula 360 CBR — Buying Comparison Guide Buying Comparison Guide · 2026 The Verdict Full Specs Performance Data Mission Fit Granfort Buying Comparison Guide Granfort 370 GTXvs.Formula 360 CBR What buyers need to know. This guide is for buyers comparing a 37-foot sport cruiser with one of the most respected performance-crossover bowriders in the market. The goal is not to decide which boat is impressive — both are. The real question is which boat better fits your mission: open-bow day performance, or a wider, warranty-backed sport-cruiser platform built for the full weekend. See the verdict Compare specs $439,900Granfort starting price $546,800Granfort fully loaded 51.1 mphGranfort top speed · factory sea trial 10 yrStructural warranty · hull + deck ABYC+ U.S. Coast Guard · certified, published Reader framing This guide is for buyers who want to understand whether Granfort should be on the first-choice list. The Formula 360 CBR is a genuinely respected performance crossover bowrider — 70 years of Formula racing DNA, a stepped FAS3Tech hull, and a design team with real Le Mans pedigree behind the pen. The Granfort 370 GTX offers a different kind of elevated experience: a 37-foot sport cruiser built around a wider beam, an enclosed dry head, an open social cockpit, published sea-trial performance, and a written 10-year structural warranty. The single most important number in this comparison isn’t only speed or price. It’s 11’6″ of beam and a written warranty. For the buyer, extra beam means more usable cockpit space, more separation between social areas, and a steadier platform at anchor — while the Granfort still delivers a factory-tested 51.1 mph top speed and a fully documented RPM-by-RPM performance curve. “That is why this comparison should begin with mission fit — not top speed.” If your goal is maximum open-bow performance and customizable power up to a triple-outboard setup, the Formula deserves serious attention — it’s a fast, well-built boat with real racing heritage. If your goal is a wider sport-cruiser ownership experience with a published warranty, certified construction, and a more enclosed weekend layout, the Granfort becomes the more serious choice. 01 Buyer education first Before comparing features, understand what you are actually comparing. This is not simply Granfort versus Formula. It is a performance crossover bowrider versus a certified sport-cruiser weekender. The Formula 360 CBR is designed around open-bow, single-level-cockpit day performance: a walk-through windshield, U-shaped bow lounge seating, a glass-sunroof hardtop, and up to triple-outboard power options topping out near 64 mph in independent testing. Formula’s own designer describes it as “a true blend of entertainment-ready comfort and the exhilarating agility that is rooted in our performance heritage.” That is the correct frame for this boat. The Granfort 370 GTX is built around a broader ownership mission. Its enclosed dry head, social cockpit, wider 11’6″ beam, published 10-year structural warranty, and ABYC/USCG-certified construction give the buyer a more complete confidence package than a customizable dayboat platform typically publishes. The difference becomes clear at the stern, where the Granfort’s open-air social layout and grill/table area create a second gathering zone beyond the cockpit. Simple decision frame: Choose the Formula if your main mission is open-bow performance day boating with flexible, race-bred power options. Choose the Granfort if you want a wider-beam sport cruiser with a published warranty, certified construction, and a lower published entry price for a comparable size class. Where each boat wins More cruiser confidence. More racing pedigree. Two very different ownership arguments. Formula deserves respect as a performance-built crossover bowrider. That makes this comparison more credible — not less. Granfort 370 GTX More warranty confidence. More certified construction. The dedicated sport cruiser argument. Granfort wins when the buyer evaluates the full ownership equation instead of the dock-side first impression: a written structural warranty, published certification, a wider beam, and a lower published starting price for a comparably sized platform. 11’6″ beam vs 11’3″ Formula 10-year structural warranty · hull + deck ABYC + USCG · certified, published in brochure $439,900 starting · $546,800 fully loaded Formula 360 CBR More power headroom. More racing pedigree. The performance-crossover argument. Formula is strong exactly where a 70-year performance builder should be strong: FAS3Tech stepped-hull engineering, a flexible power ladder up to triple outboards, and a design language shaped by Formula 1-trained hands. 63.4 mph tested · triple 400 HP outboards 6’2″–6’4″ published cabin headroom FAS3Tech stepped hull + structural grid 70 yrs Formula performance heritage Published performance data Performance should be measured, not guessed.

Granfort 370 GTX vs Regal 33 XO Comparison

/ June 19, 2026

Granfort Buying Comparison Guide Granfort 370 GTXvs.Regal 33 XO Two different sizes, two honest engine packages — what does the extra foot, beam, and horsepower actually cost? This guide compares the Granfort 370 GTX against the Regal 33 XO, one of the best-known names in American express cruisers — family-owned since 1969, backed by a genuine Lifetime Limited Structural Hull Warranty, and a multiple-time J.D. Power Customer Satisfaction Award winner. Unlike a same-power matchup, these two factory tests were not run on equal horsepower: Granfort’s sea trial used twin 400 HP Mercury Verado outboards (800 HP total), while Regal’s factory performance test used twin 300 HP Yamaha F300 outboards (600 HP total). We’ve kept that difference visible throughout rather than hiding it — and it’s still worth the comparison, because Granfort’s published starting price undercuts Regal’s own published MSRP on a larger, more powerful boat. See the verdict Compare specs $439,900 Granfort starting price  $37,500 Below Regal’s own $477,400 MSRP  800 HP Granfort total · vs Regal’s 600 HP tested  10 yr Granfort structural warranty · hull + deck  ABYC + U.S. Coast Guard · certified, published   Reader framing This guide is for buyers who want to know what a smaller engine and a longer American heritage actually get you. Regal Marine Industries is one of the most established family-owned boatbuilders in America — founded in 1969 by Paul and Carol Kuck in Orlando, Florida, still run by the Kuck family, with more than 75,000 boats built and multiple J.D. Power and Associates Customer Satisfaction Awards to its name. The 33 XO carries that heritage into a walk-around outboard express cruiser: trim-up outboards for easy beach access, a slide-out UltraLounge that extends cockpit seating by 11 inches, and an available PowerTower. None of that is in dispute. What’s easy to miss is that Regal, unlike some heritage builders, does publish pricing — its 2024 model-year 33 XO carries a $477,400 MSRP, and current listings across major marketplaces run roughly $227,000 to $549,727, averaging near $336,400 (a range that blends new boats with older, lower-powered used models back to 2018). A fully loaded Granfort 370 GTX starts at a published $439,900 — cheaper than Regal’s own new-model MSRP, on a boat that’s roughly two to three feet longer, about 14 inches wider in beam, and running 200 more combined horsepower. “Granfort’s factory sea trial used twin 400 HP Verado outboards; Regal’s factory performance test used twin 300 HP Yamaha outboards. This is not an equal-power comparison — and that’s exactly why it pays to read past the raw speed numbers.” If your priority is a proven, JD Power-winning American builder with a genuinely longer hull warranty and real-world fuel efficiency, the Regal deserves serious consideration. If your priority is more boat — more beam, more horsepower, more cabin — at a starting price below Regal’s own MSRP, the Granfort is hard to overlook. Buyer education first Before comparing features, understand what you are actually comparing. This is not simply Granfort versus Regal. It is a larger, more powerful sport cruiser versus a lighter, more fuel-efficient express cruiser from a 57-year-old American builder — and both are twin-outboard boats with published pricing, which is what makes an honest comparison possible in the first place. The Regal 33 XO is built around walk-around, beach-friendly day and overnight boating: trim the outboards up and back the transom right onto the sand, slide the UltraLounge back for 11 extra inches of cockpit seating, and convert the cabin settee into a queen berth for the occasional night aboard. Regal’s twin 300 HP Yamaha F300 package (600 HP total, as factory-tested) is noticeably lighter on fuel than a bigger V10 rig — a real, legitimate selling point for owners who prioritize efficiency and lower running costs over outright horsepower. The Granfort 370 GTX is built around a different value proposition: a wider 11’6″ beam, an enclosed dry head, twin 400 HP Verado outboards (800 HP total, as factory-tested), a published 10-year structural warranty, ABYC/USCG-certified construction — and a starting price that undercuts Regal’s own published MSRP despite being the larger, more powerful boat of the two. Simple decision frame: Choose the Regal if a proven, lifetime-warrantied American builder and meaningfully better fuel economy matter more to you than raw size and horsepower. Choose the Granfort if you want more beam, more power, and more cabin than a 33 XO, for less money than Regal’s own new-model MSRP. 370 GTX Regal 33 XO Where each boat wins Different horsepower, different hull size — and two genuinely different ownership arguments. Regal earns its efficiency and warranty advantages honestly. Granfort earns its size, power, and price advantages just as honestly. Neither brand needs the other one weakened to make its case. Granfort 370 GTX More beam, more horsepower, a lower starting price. The bigger-boat-for-less argument. Granfort wins on scale: a wider cockpit, an 800 HP twin-Verado package, and a published starting price that’s still below Regal’s own new-model MSRP — despite being the larger boat. 11’6″ beam vs Regal’s 10’4″ (14% wider) 800 HP total (twin 400 Verado) vs Regal’s 600 HP tested $439,900 starting — $37,500 below Regal’s $477,400 MSRP 10-year structural warranty · hull + deck, published Regal 33 XO A lifetime warranty and a lot more mileage per gallon. The proven-efficiency argument. Regal is strong exactly where a 57-year family-owned American builder with a JD Power track record should be strong: real fuel efficiency, brisk acceleration, and a warranty that’s measured in a lifetime, not a decade. 0.95 mpg at wide-open throttle — vs Granfort’s 0.69 mpg 7.1 sec 0–30 mph — quick for a 600 HP twin-outboard cruiser Lifetime Limited Structural Hull & Deck Warranty, published 57 years family-owned · 75,000+ boats built · multiple J.D. Power awards Published performance data Different horsepower, so the numbers need context — not just a headline speed. Granfort’s figures come from its factory sea-trial report for hull #FK370GTX-67, twin 400 HP Mercury Verado outboards (Aug 2024). Regal’s figures come from its own factory performance-test sheet for the 33 XO, twin 300 HP Yamaha F300UCA outboards, dated Feb 3, 2017.

A different power entirely. The Granfort 300 GTX is powered by two Mercruiser Fourstroke V-8 4.5L 300HP outboard engines — 600 HP total. This is a fundamentally different boat from the 300 GTS, which uses a single inboard engine. The twin outboard configuration gives the GTX immediate, responsive power delivery, effortless joystick docking capability, and the confidence of redundant propulsion on the water. At 9.10m LOA on a 2.80m beam, the 300 GTX produces a GPS-confirmed 49.9 mph top speed with 2 persons and — remarkably — 49.7 mph with 11 persons aboard. The hull barely notices the load. This is the factory test data: real numbers, named source, GPS-confirmed. Starting at $234,700 with twin 200HP, or $265,500 fully configured with twin 300HP — the 300 GTX is the entry point to the Granfort twin outboard experience.
