Jascat is in excellent condition and ready to go on your adventure.  This is the shallow draft, light weight performance version that made the legend.

The Gemini 105 Mc Catamaran, the perennial best-selling cruising catamaran with great accommodations, light and airy spaces and good sailing performance all at an affordable price.

The Gemini 105 Mc features an efficient hull shape, trusted kick up centerboards and rudders, an 18 inch draft and extremely manageable 14 foot beam. The Gemini 105 Mc interior and deck mold makes the boat strong, light and fast with great cruising amenities.

Accommodations feature the master queen cabin forward and two double cabins aft. The Salon has a dinette settee with a 3-piece table suitable for casual seating when closed or dining when open. The dinette table easily converts into a berth for two.

To Starboard is a large galley with opposing work surfaces, double sink, refrigerator and two burner stove with oven and broiler. Rather than Galley up or Galley down we describe the layout as Galley Open, as it is open to the entire Salon and you stand at eye level with the windows but you are standing on the hull floor.

Forward to Port is the head with counter space, wash basin and shower with an isolating door and two storage lockers.

The cockpit is designed for great seating with easy ingress and egress facilitated by normal sized steps to the deck in each corner.

The solid foredeck provides a safe work area when needed to a spacious lounge area for calm sailing days or when the vessel is at rest.
