Invincible 40 Catamaran, Specs, Performance and Used Prices

Who is looking at an Invincible 40 Catamaran for sale

Anyone searching for an Invincible 40 Catamaran for sale usually fishes offshore seriously, often from South Florida, the Carolinas or the Gulf, and has decided that a catamaran's flat ride and stability at rest beat a deep-V for their kind of water. The 40 Cat sits at the center of that small, specialized market, and it has a cult following among tournament anglers and Bahamas regulars.

Invincible Boats was founded in 2006 in Opa-locka, Florida, and built its reputation on high-performance offshore center consoles. The all-new 40-foot catamaran arrived for the 2018 model year, at a base price of $535,000 with quad Mercury 350 Verados. Ownership changed in July 2019, when EagleTree Capital bought the company; Invincible now sits within Warbird Marine Holdings alongside Yellowfin, another South Florida builder of fast fishing boats.

Invincible built catamarans before the 40, so check the year and hull generation of any listing carefully. The 40 was the first Invincible to use the current Morrelli and Melvin hull, and that hull is the reason to buy one.

Why Morrelli and Melvin's sponsons lean into a turn

Morrelli and Melvin made its name designing America's Cup and racing multihulls, and Pete Melvin brought that thinking to the 40 Cat. The key idea is the semi-asymmetric shape of each sponson. Traditional powercats with symmetrical tunnels tend to turn flat or even lean outward, which feels unnatural and throws people around in the cockpit. The Invincible's sponson sections let the boat bank inward through a turn, so it handles more like a deep-V monohull while keeping a cat's stability.

A center pod between the sponsons splits incoming water before it reaches the tunnel roof. That reduces the bow-to-stern hobby-horsing that afflicts some cats in a short, steep head sea, and it helps the boat hold speed through waves rather than slowing at every crest. Stepped running surfaces reduce wetted area at speed, which explains the 70-mph top end.

The draft is only 22 inches, which makes the boat useful on the Bahamas banks and in shallow inlets, and at 16,000 pounds with engines it is light for a 40-footer carrying 640 gallons of fuel.

Quad Mercury 350 Verado test numbers

Sport Fishing and Boating both tested the 2018 boat with four Mercury 350 Verados. Invincible measured a top speed of 71 mph, about 62 knots, at 6,400 rpm with a full load. Boating's test boat carried seven people, 400 gallons of fuel, 500 pounds of fish, 300 pounds of ice and 180 gallons of livewell water, which is a realistic tournament load, and still reached 30 mph in under 10 seconds. Sport Fishing recorded 8.7 seconds to 30 mph.

Efficiency peaks around 3,500 rpm and 33 mph, where the boat returns about 1 mile per gallon. With 640 gallons aboard that means a range of more than 600 statute miles, roughly 520 nautical miles, enough for a Bahamas trip without refueling or a long canyon run off the Northeast with plenty in reserve. At 4,000 rpm and 40 mph the quads burn 41.8 gph combined, and a fast 55 mph cruise still returns 0.91 mpg.

Those are remarkable numbers for a boat that also carries close to 900 gallons of fish box capacity. The catch is that four outboards cost four times the service, and running at 55 mph offshore is only comfortable in moderate seas no matter how good the hull is.

Livewells, fish boxes and an 11-foot cockpit

The layout is built around fishing first. The aft cockpit measures about 11 by 5.4 feet with 26-inch gunwales, deep enough to brace against while fighting a fish. Twin pressurized 55-gallon livewells sit in the transom, with a third 72-gallon well under the cockpit sole, so live-bait sailfish and tuna crews can carry plenty of bait.

Fish storage is enormous. Boating's test boat had a 268-gallon box to starboard and a 414-gallon box to port below the aft cockpit, plus two 158-gallon boxes forward, and a 960-quart coffin box ahead of the console doubles as a padded lounger with rod holders. Two 8-foot dry lockers swallow rods and gaffs.

The console houses a small cabin with about 4 feet 1 inch of headroom, enough for a head, changing space and gear storage rather than overnighting. Electronics on the tested boat included twin Garmin GPSMap 8617 displays, and raw and fresh water washdowns feed from an 82-gallon freshwater tank.

• Two 55-gallon pressurized transom livewells plus a 72-gallon well
• About 898 gallons of fish box capacity across four boxes
• 960-quart coffin box forward with lounge cushion
• 26-inch gunwales and an 11 by 5.4-foot aft cockpit
• Two 8-foot dry lockers for rods and gear

Twin, triple or quad, and how to choose

Invincible rated the 40 Cat for up to 1,600 hp of Mercury or Yamaha outboards. Quad 350 Verados were the launch configuration, and quad 400 hp outboards reach the full 1,600 hp rating. A rig of fewer, larger outboards cuts maintenance and weight, but it gives up redundancy and should be checked against the builder rating before you buy one.

For offshore fishing, the quad setup has real advantages beyond speed. Losing one engine 80 miles out still leaves three working, and the boat will run on two at a useful cruise. The disadvantages are fuel cost at high speeds, four sets of service and a large repower bill. Before buying, confirm the engines' hours, compression readings and lower unit oil samples for all four.

What it costs to keep a 40-foot fishing cat

Running costs depend mostly on how far and how fast you fish. An owner who runs 200 hours a year at 40 mph will burn roughly 8,000 gallons of fuel. Add outboard service for four engines, bottom paint, electronics, insurance for a $500,000 to $800,000 high-performance boat and dockage, and a realistic budget is $55,000 to $110,000 a year. High-performance boats can face higher insurance premiums, especially for younger owners or those with limited experience.

The 12-foot beam is a big advantage over cruising catamarans. Most marinas, dry stacks with heavy-capacity forklifts and trailers that can handle this weight will take it, and it fits a standard 40-foot slip in most places.

Used values and what moves the price

Invincibles hold their value well among high-performance fishing boats, helped by low production numbers and a loyal following. Our 2026 estimates run from about $360,000 for a 2018 boat with original quad 350s and high hours to about $800,000 for a 2023 boat with newer, more powerful outboards and low hours.

Engine hours and warranty status matter more than cosmetic condition. A boat that has already been repowered with low-hour engines can be worth $150,000 more than an otherwise identical boat on original power. Tournament history is not a bad thing, but it usually means hard use, frequent high-speed running and heavy bait and fish box use, so inspect pumps and plumbing carefully.
