About the GEMINI 105MC
GEMINI 105MC is a development of the 105M with a number of interior updates. Most visibly, however, the cockpit of the 105Mc can be temporarily enclosed with either canvas or solid panels.
The Gemini 105MC is a catamaran designed by Tony Smith and built by Performance Cruising Inc. in the USA from 2003 to 2011. With a displacement of 8000.0 lb and a beam of 14.0 ft, it offers a comfortable cruising platform, though the exact number of hulls built is not specified in the available data.
- Best for:
- This vessel is well-suited for coastal and nearshore cruisers who prioritize interior volume and ease of handling, as evidenced by the high prevalence of solar panel (97 mentions) and canvas upgrades (96 mentions) for extended stays.
- Bluewater capability:
- With a capsize ratio of 2.8 and a comfort ratio of 11.4, the boat is capable of offshore passages, though owners frequently install watermakers (30 mentions) and wind generators (13 mentions) to support extended bluewater cruising.
- Comparables:
- Comparable boats include other Performance Cruising catamarans and similarly sized production cats from the early 2000s, such as the Lagoon 33 or Fountaine-Pajot Bastide 42, which share similar beam-to-length ratios and dual-engine configurations.
