Invincible delivers its most compact cat to date with many big-boat features.

Invincible Boats and design firm Morrelli & Melvin have hit their stride with the latest debut in Invincible’s five-model catamaran lineup, all of which feature hybrid semi-asymmetrical hulls. The design of the 33 Catamaran provides a high-performance ride, comfortable turning and superior sea-keeping characteristics.

The South Florida builder provided my test boat in mid-August. It came equipped with twin Mercury Verado supercharged 400 hp outboards, which pushed the hull to nearly 62 miles per hour with four crew and 100 pounds of gear. The cat jumped to plane in about 6.5 seconds and hit 30 miles per hour in 11 seconds.

Ok, all that is cool, but what’s really cool is the way this boat handles. Crisp, comfortable turns feature none of the awkward outward heeling of symmetrical cats. The twin sponsons also work best together when they have chop to deal with.

Fish Features

As a fishing platform, the 33 features outstanding stability at rest and when trolling. Bolstered inwales cushion the thighs, and the gunwales themselves rise to a comfortable height for wiring, releasing or gaffing a fish.

A 65-gallon oval livewell centered on the transom is flanked by a starboard transom door and a pair of port-side storage drawers. An in-deck livewell (also 65 gallons) adds capacity, and both tanks are fed by a sea chest with four pumps.

Rod holders are almost too numerous to count; it took three of us five minutes to agree on a count of 47 between the transom, gunwales, leaning post, hard top and side-console racks.

Mezzanine seating behind of the three-man leaning post doubles as a rigging station when the seatback is folded down. In that compartment, I found four drawers in two lockers flanking a center utility box. On each side of the leaning post, I saw two more compartments.

Comfort Factors

You’d expect a lot from a 33-foot boat with a 10-foot-3-inch beam, and Invincible delivers numerous features. The center console (from the 36 Open Fisherman) and leaning post (from the 35 Catamaran), as well as a new-size hard top all fit beautifully, leaving wide walkways to either side. On the helm face, Invincible provides plenty of room for two 20-inch displays, a VHF radio, Mercury VesselView gauge and Fusion audio controller. The hard top is ported to stow longer rods, and acrylic windscreens protect passengers from the weather.

When the day’s fishing ends, families find loads of seating for a dinner under the stars. A double lounge graces the front of the console, and beneath it, a large compartment comes equipped with a head. Invincible has considered all of the variables to deliver the right formula for a great day on the water with family and friends.
