Is the Invincible 33 Catamaran a Perfect All-Rounder?

When it comes to innovation in centre consoles, its hard to go past Invincible with their new age approach of incorporating racing technology with fishability. We were lucky enough to catch up with Sam Wallrock from Boat Monster at the Sydney International boat show to take a look at the Invincible 33 catamaran.

Who are Invincible

Founded in 2006, Invincible Boats has built its reputation on semi-custom, high-performance, saltwater sportfishing boats. In 2016, they tapped the hull design skills of Morrelli & Melvin to craft an exceptional design for their first power catamarans. Now they’ve put their big cat performance into a smaller form. The Invincible 33′ Catamaran promises all the versatility, agility, and speed of its larger siblings. Can it deliver? Let’s take a closer look.

Meet the Invincible 33 Catamaran

The Invincible 33′ Catamaran is a centre console power cat introduced in October 2020 at the Ft. Lauderdale International Boat Show. And it got a lot of attention. Pre-orders began flooding in. And why not? Invincible’s boats have a reputation for their speed, stability, and fishability. And the 33′, their fifth catamaran and tenth boat overall, is no exception.

It has a 33’11” (10.3m) LOA with a 10’3″ (3.1m) beam. That ratio makes the 33′ exceptionally stable, even in rough waters. The single-level deck and 360º walk around to enhance its fishability.

Twin outboard motors with a maximum of 900 HP ensure the Invincible 33′ Catamaran will get you where you want to be in short order. Being able to customize it to your liking lets you make sure your boat is unlike any other.

Invincible Advantages

Like all Invincible boats, this cat is built for fishing. It’s specially designed for serious offshore anglers.

Unlike most power catamarans in the market Invincible have moved away from the usual power cat which is generally driven from midship on the port or starboard. Making this a centre console cat creates a more spacious and stable boat whilst giving you a 360 degree walk-around deck allowing the anglers to fish whatever style they want.

Multihull VS Monohull

While not as popular as single hulls, catamarans definitely have a special place in inshore and offshore fishing. Drawing less than a single-hull yet being a lot more stable when at rest is a huge advantage compared to a monohull.

There is a wide beam that runs the length of the boat thanks to the multihull design, this extra beam allows the boat to be a lot more stable at rest compared to its single-hull counterparts.

The Invincible 33 Catamaran’s deck creates an abundance of space. So, there’s plenty of room for you and several mates to fish without tripping over each other.

The Invincible Hull

Each Invincible catamaran model utilises the patented hybrid semi-asymmetrical multihull design created by Morrelli & Melvin exclusively for Invincible.

Anyone that has been on a catamaran knows that feeling of a cat heeling on a turn or a following sea, with the Morelli & Melvin design it allows the boat to turn without heeling. It remains perfectly level at all speeds—which is an amazing feat.

The dedicated twin-outboard platform with a max 900 HP means it has plenty of power. Invincible recommends you run the cat with twin 400 HP outboards for best performance.

Invincible predicts a top speed of at least 60 knots and a 25– 35 knots cruise speed. The 400-gallon (1514 litres) fuel capacity means the 33′ Catamaran can go the distance too.

The helm can be outfitted with Garmin or Simrad electronics, fusion audio, and JVS speakers.

Invincible Catamaran Advocate

As actions speak louder than words, professional angler and three-time world sailfish champion, Peter Miller recently traded in his monohull for a multihull. Peter is a producer, philanthropist, and is now an Invincible Ambassador.

Miller says, “I’ve seen my share of catamarans in my more than 30 years of fishing, but it wasn’t really until I started traveling the world with ‘Uncharted Waters’ and noticed that the most rugged fishermen were the ones who ran the cats,’ Miller said. ‘When I went to some of the places with the most challenging conditions – South Africa, and Anguilla, for example – I saw that the catamarans are preferred. When I finally got to fish one for myself, doing a couple hundred miles roundtrip on an Invincible 40’ Catamaran, I saw that catamarans are where it’s at.”

She’s a Beaut!

The Invincible 33′ Catamaran has the same sleek lines as the 35′ and 46′, but with some added flair of its own. The smaller size makes this fishing machine trailerable which is going to cut down costs of maintenance for the owner in the long run.

If a smooth ride, extra space, and high performance appeal to you, then the Invincible 33 Catamaran may be the fishing platform you’ve been waiting for! Contact Boat Monster –
