Broker's Comments

Boatshed Essex are pleased to be presenting this fast, spacious and capable catamaran. The Gemini 105MC is the upgraded Gemini Catamaran, narrow enough to cruise European Canals to the Mediterranean and robust enough for crossing seas.

The Gemini is packed with space and performance, with three double cabins, a separate shower and heads room, large galley with acres of worktop space and a saloon that comfortably seats six. It is no surprise these are popular long term cruising platforms and even liveaboard boats.

The sail performance for a multihull is comparatively good, with a large mainsail, improving upwind performance and a Genoa that makes downwind sailing straightforward. Manoeuvrability in close quarters is helped considerably with a powerful Westerbeke engine and steerable drive.

This version has benefited from a number of recent investment packages including a professional valet inside and out, engine servicing and new parts where required.

If you would like any more details or to organise a personal viewing, then please do contact our office and we would be pleased to help.
