Description

ROCINANTE is a proven Formosa 46 offshore cruising yacht combining traditional heavy-displacement construction with practical modern upgrades where they matter most.

Based on a Doug Peterson-influenced design with close lineage to the respected Kelly-Peterson 44, the Formosa 46 was built for serious cruising. ROCINANTE features a cutter rig, protected skeg-hung rudder, substantial displacement, excellent storage, and a practical interior designed for extended time aboard.

More importantly for buyers considering a yacht of this vintage, several of the expensive and difficult upgrades commonly associated with older Taiwanese cruising boats have already been completed.

• Original teak decks professionally removed and replaced with durable non-skid

Below decks, ROCINANTE offers two large private staterooms positioned at opposite ends of the boat, two heads, generous salon seating, a secure offshore galley, dedicated navigation station, pilot berth, and substantial storage for extended cruising.

Her current owners sailed her from the San Francisco Bay area to Mexico in 2023 and have since used her for extended cruising throughout the Sea of Cortez and Pacific Mexico. She is currently stored on the hard in San Carlos.

For a couple or small family looking for a large, capable bluewater cruiser at an accessible purchase price, ROCINANTE offers an unusual amount of boat, equipment, and completed upgrade work for the money.
