About the GEMINI 3400

The GEMINI 3400 was the predecessor to the GEMINI 105 and the first in the series to have molded transom steps. A new kick-up rudder system was developed for the new transom design. Like all Gemini models the 3400 has kick-up centerboards which are housed in low aspect ratio fixed keels which serve as protection for the under-slung rudders from damage when grounding.

Sailpages Buyer's Take

Designed by Tony Smith and built by Performance Cruising Inc. from 1993โ€“1996, the Gemini 3400 is a compact multihull with a production run of 44 hulls. Its 8000.0 lb displacement and 14.0 ft beam define a lightweight, wide-beamed platform that prioritizes interior volume and ease of handling over heavy offshore displacement.

Best for:
This boat suits coastal cruisers and short-to-medium range travelers who value easy single-handed handling and shallow draft access. It is ideal for owners seeking a manageable multihull with ample interior space, provided they are diligent about maintenance.
Bluewater capability:
With a capsize ratio of 2.8 and a comfort ratio of 11.75, the boat is designed for coastal and protected waters rather than heavy offshore passage-making, though its twin keel configuration offers safe grounding capabilities.
Comparables:
Comparable boats include the Lagoon 33 and Beneteau First 34, which share similar production eras and target the same market of lightweight, performance-oriented cruising multihulls or small monohulls with high comfort ratios.
