Endeavor is a 1999 Gemini 105M built by Performance Cruising in Annapolis, Maryland, Hull #648.  She is 34′ long and 14′ wide.  The 105M is a catamaran, having two hulls, and is rigged as a sloop, with a main sail and foresail. We have a spinnaker to be deployed for downwind runs.


Catamarans depend on their width for stability, and not on traditional ballast in the keel.  Thus Endeavor is about 5,000 lbs lighter than our last 34′ boat, the Hunter 340.

Because of its rectangular floor plan, the 105M also has considerably more usable floor space than a mono hull of the same length.

105M Floor Plan

For the waterways we plan to travel the 105M hulls are ideal: with swing-up centerboards and rudders, she can navigate in as little as 18″ of water.  This allows us to anchor closer to shore or even beach her.  We can also sneak into harbors and bays off limits to other sailboats with fixed keels. In the left photo below we are tied up in Little Sand Bay Harbor (Apostle Islands), with a depth less than 3′. On the right She is beached at Big Bay in the Apostle Islands.

Two other advantages of the 105M are flat sailing and expansive deck space.  As a catamaran, she sails “flat” and does not heel more than 5 degrees.  Objects stay put and moving about on deck is safe.  The large front deck allows the use of lawn chairs on mild days, as shown by the Admiral below.

Endeavor has most of the comforts of home, on a much smaller scale.  Some items on board include:

  • Microwave
  • LP Oven/Range
  • Upright Fridge with Freezer
  • Stainless double galley sink
  • Lots of storage space
  • Bamboo flooring
  • Pressurized fresh water system
  • Shower with on-demand heat
  • Composting head (toilet)
  • Air Conditioning and Heat
  • LED lighting
  • Queen-size master berth
  • Two double berths
  • U-shaped saloon table which converts to large bed
  • Hammock
  • Plenty of hatches for ventilation

She was originally powered by a 3 cylinder diesel engine with a unique drive leg built in England.  When we bought her we knew the engine had high hours and when it died we converted to a 4-stroke Honda outboard.  Many Gemini owners have done so, with the Honda being quiet, getting about 10 mpg when motoring (infinity mpg under sail!), have electric tilt, being stone reliable, and having parts available everywhere.  Both the diesel and now the outboard share the feature where the drive turns with the rudder.  This makes Endeavor maneuverable in tight places.

Endeavor is a fast sailboat by cruising standards.  Her narrow hulls knife through the water instead of plowing like our previous mono hulls.  Under sail we have often exceeded 9 knots average.  Might not sound like much compared to a car, but it is almost 150% of what we could achieve in our Hunter 340.
