33’ Aluminum Catamaran – LSB3311

The 33’ x 11’6” LSB3311 Aluminum Catamaran, designed in collaboration with Noah Thompson Designs of New Zealand, is a rugged, heavy-duty vessel engineered for both recreational and professional use. Built for rough conditions and long days on the water, this catamaran combines durability, stability, and versatility, making it the perfect 6-passenger charter boat (plus crew). It’s equally at home running sightseeing excursions, whale watching tours, fishing charters, diving operations, survey work, patrol duties, or hardcore offshore recreation.

With its wide stance and proven twin-hull design, the LSB3311 delivers exceptional stability, strength, and comfort in heavy seas, ensuring a safe and reliable ride even in challenging offshore environments.

Why It Stands Out

• The LSB3311 is built for operators who demand rugged reliability, offshore stability, and passenger comfort in all conditions. With its corrosion-resistant aluminum construction, long service life with minimal maintenance, and adaptability for both professional and recreational applications, this catamaran is the ultimate platform for 6-passenger charters and beyond.
