Tangaroa Mk IV Sailboats for Sale & Market Overview

The Tangaroa Mk IV represents a pivotal evolution in James Wharram’s "Classic" series of Polynesian-inspired catamarans. At 35 feet (10.67 meters) in length, it was designed as a blue-water cruiser capable of transoceanic passages while remaining accessible to the home builder. Unlike modern production catamarans that prioritize bridgedeck cabins and high-volume hulls, the Tangaroa adheres to the strict Wharram philosophy of "sea-kindliness through flexibility," utilizing a V-shaped hull profile and a functional, open-deck layout. The Mk IV iteration specifically refined the beam-to-hull connections and interior ergonomics compared to its predecessors, solidifying its reputation as a rugged, minimalist voyaging tool. This design is often categorized alongside its larger sibling, the 40-foot Narai, and its smaller predecessor, the 30-foot Hinemoa, all of which share the distinctive "double-canoe" aesthetic documented extensively by James Wharram Designs.
