WHY NAJOLATECH
Engineered, not improvised.
Stepped Catamaran
Symmetrical stepped hull with a twin-hull stance — stable at rest, efficient at cruise, level under load.
CFD + FEA Validated
Hull form optimized in computational fluid dynamics. Structural components stress-tested in finite element analysis.
Vinylester Composite
Hand-laid and vacuum-infused with premium marine-grade resin. Sized for years of offshore service.
โBUILT FOR THE OFFSHORE
Built for serious water.
The 343 is a purpose-built offshore platform. The design priorities were range, capacity, and cockpit real estate.
โ
502 gallons of fuel give you the legs to fish further out and stay longer. On twin 400s the 343 returns roughly 1.4 miles per gallon at cruise, which works out about 700 miles of range on a single fill. That is range you simply do not find on a 34-foot center console.
โ
The symmetrical stepped catamaran hull is the foundation, hard-laid, vacuum-infused, and validated digitally before tooling was cut.
โ
Every 343 is rigged to run a minimum 700 HP power package and configured to your fishery, your style, and the way you actually use the boat.
Range. Capacity. Cockpit space.
FISHABILITY
Designed for how you actually fish.
Every fishing feature on this boat earned its place — built around real time on the water: trolling spreads, bottom rigs, kite fishing, bait handling, gaffing, icing.
Standard livewells are dual 55-gallon corner units (port and starboard) plumbed off a fiberglass pump box. Optional below-deck livewells add capacity without taking up cockpit space. Four macerated ice boxes drain clean and hold cold through long days. The insulated bow coffin box is sized for a trophy, raw-water washdown clears the deck between fish, and the cockpit self-bails so heavy seas stay outside. Rod holders are angled for trolling and bottom-fishing, rocket launchers ride the T-Top, and outrigger mounts are factory-integrated — not bolted on later.
Built around the actual workflow of a fishing day.
PERFORMANCE
Power & ride control.
Every 343 comes with a 700 HP minimum power package, with twin and quad outboard configurations available across all four major brands — Mercury, Yamaha, Honda, and Suzuki.
Ride control is integrated, not bolted on. Zipwake PRO auto trim tabs are standard. Optional Seakeeper Ride vessel stabilization is available for further attitude control. Mercury Electric Steering pairs with Mercury power packages, with Dometic and Optimus available as alternatives. Ready-to-fish weight is roughly 14,000 lbs — the stepped hull and twin-hull stance keep the boat efficient at cruise and level at rest.
700 HP minimum. Integrated ride control. All four brands.
ENGINEERING PROOF
Validated before tooling was cut.
The hull was designed and validated digitally before any moulds were built. Computational Fluid Dynamics (CFD) optimized the hull form, stepped geometry, and water flow across a range of speeds and loading conditions — the result is a hull that planes efficiently, tracks predictably, and runs with low drag at cruise.
โ
Finite Element Analysis (FEA) stress-tested every bulkhead, stringer, and laminate schedule against extreme loading. Maximum total deformation came in at 2.13 mm, with every structural component well inside its required safety factor. All moulds and structural components are CNC-machined from the validated CAD data — no hand-shaping, no guesswork.

CONSTRUCTION
Hand-built. Inspection-verified.
The 343 hull is hand-laid and vacuum-infused with premium vinylester resin. The composite structure delivers a strong strength-to-weight ratio and excellent resistance to osmotic blistering over years of service.
โ
Precision core placement and vacuum-assisted resin infusion give consistent laminate quality without dry spots or voids. Every hull is post-cured, inspected, and documented — each build stage signed off by quality control before the next begins.
