Pros:
Cons:

The Gemini 105mc sails exceptionally well, and even points well with the centerboard set properly. In winds 15 to 25 knots it sails with 36-38 foot monohulls (if the monohull is sailed well), and is comfortable with winds up to around 32 knots (a common occurrence on SF bay). As a multihull it is easy to reef, and heaves to, and stays hove to, with celerity. It is almost too comfortable, though, again, on SF bay, that means we are often the only ones out on a cold day.
We bought our Gemini new and, except for some gel cracking, have had few new boat problems--especially compared to a friend who bought another brand of cat (of about the same length) new and has spent an extraordinary amount of time basically finishing the boat.
A beam reach down the bay, with guests relaxing in the love seat, is a treat.

Pros: stable, comfortable, well designed, centerboard in each hull
Cons: Lite (cracks) construction -surface cosmetic cracks, but strong overall

I purchased our Gemini 105MC, Avalanche, new in 2/04 with the screacher, solar panels, cockpit enclosure and screens, upgraded batteries and Balmar charger, cabin heater, microwave, transom seat and davits. Great platform for kids and adults as a three cabin plus dinette boat, and sails well. Motors efficiently (holds another 40-50 gallons of diesel beyond the 36 gals in tanks easily in 5 gal plastic jerry cans externally in aft hull lazarettes) and handles 4-5 foot seas and higher winds.

Have sailed her from Annapolis to Block Island/Narragansett Bay for a spring and summer sojourn, then that fall to Punta Gorda, Fla down LI Sound, offshore to Norfolk, down the ICW to Bald Head Island, then offshore to Charlestown, down the ditch to Stuart and directly over to Ft. Myers.This was a four installment trip in between hurricanes and a tree stump damage in NC.

Have had green water repeatedly over the hard dodger and she performed well. I upgraded the electronics with gps and radar and she navigates well. The cockpit enclosure is wonderful to keep the crew warm and comfortable as well as out of the sun. Once south, I now need to consider how and what generator to use to enjoy the 16.5k btu reverse cycle air on the hook, but have not solved that yet.

As a monohull owner as well, it has taken a bit to enjoy moving when the wind hits you, not just heeling, and to enjoy not putting everything away before the hook is raised as things stay where they started in the boat while underway. The major threat is wakes from passing large displacement power boats in the ICW or elsewhere if you can't turn into the wake due to the narrowness of the channel, etc. What you don't have is protection of your running gear by a keel or hull using the one powerleg which is midway between the hulls and unprotected as evidenced by finding a submerged tree trunk north of the Alligator Punga canal on the ICW in NC. We now clearly understand that this is North Carolina's system of collecting money for repairs for transient sailors using the waterway.

That being said, this system of the power leg being connected to both rudders gives substantial control of steerage without a bow thruster or the expense and weight of dual diesels. But Sonic drive legs are sensitive and easily prone to 'bearing' wear even with appropriate and full lubricants when used for moving your vessel long distances with the Westerbeke 27 hp diesel. They are very expensive to replace due to being 'stocked' across the pond at the manufacturer. Yet the convenience of lifting it out of salt water and hence no corrosion is great.

So there are pluses and minus to all. Nicely, the biggest challenge with this boat is to remember that catamarans perform better with less weight. Despite the more than ample storage space, unlike a monohull, don't take the kitchen sink with you, your catamaran won't perform as well if you do. Great boat, glad I bought her.

Pros: Price
Cons:

I bought hull #987, put the money down in Feb 2007 and took delivery on time with no problems in May 2007. Since then the lift pump failed due to a faulty connection (westerbeke's fault); the 110v to the dometic propane powered refridge has never worked right (i've reported it, gotten excellent help, but am working it out myself rather than having PCI fix it); the transmission needed flushed and refilled at 50hrs - I think the fluid was low from the start. Otherwise it's been a great summer of learning the boat, with no problems at all.
The Gemini 105MC is as the builder says, built to a price (149k base for mine). I put on most of the options, no cockpit cushions, heater or microwave, pretty much everything else added in - then had 4 110v outlets, 8 12v outlets, a Horizion 600 anchor windlass and a totally revamped battery, charger and monitoring system installed. Total delivered price 173k, with 7k going to after factory installation by PKYS (www.pkys.com)
Here's the bottom line, you can't buy another USED Cat less than 10 years old for that, period, finito, exclaimation mark.
The Tomkat 9.7 comes close, but to me they just are not comparable (despite Prac Sailor's comparision, the 9.7 just doesn't have the accomodations of the Gem, come on, open 'master' cabin?).

Gem's are built with the understanding of the owner that some of the finish work, custom systems, etc..are the owners to do. It's not a volkswagen beatle but it's also not a Chevy or Ford vs Cadillac thing - think Honda Civic and you want a soup bowl exhaust - nice, not needed.
If you don't want to be a hands on owner, by a different boat or be rich and hire it out.
I live and sail in the Annapolis Md area; steep chop on the bay can cause bridgedeck slap, and I've had the bows bury and green (okay brownish) water over the deck and down the hatch in the 5ft steep wakes and waves you can get on the bay. I have never felt that I or the boat was in trouble or anything but satisfaction that the boat was working as designed. In flat water she makes 7.5kts at 80% rpm.
I have motored into 35kt head winds and made 5.5kts SOG per my GPS.
I have sailed in over 20kts puffs, pay attention to reef points and heel angles. 8.5kts in 12kts of wind is sustainable - as is 4kts in 6kts of wind. They sail nice, they sail mostly flat. I like the idea of being able to hoist the hook and go, and not have to worry about putting things away BEFORE I hoist.

Things I'd change -
The drive leg - it works, it just worries me it might break; there are issues.
More Fabric choices for inside (wife's input).
The 'caulk' technician at the factory, needs to learn tape and cleanup skills.

I'd buy another but why? This one will last me for a good long time.

Pros: centerboard. rudder design innovations; good galley;dry as a bone inside
Cons: outdrive problems outdrive is. a good design idea poorly executed; parts a problem

If you can live with the tempermental outdrive leg and make sure you have a Plan B when your outdrive leg slips out of reverse, you'll have a ball.

Pros:
Cons:

I do not own a Gemini, nor have I sailed a Gemini, but I have noticed a common complaint with the "drive leg" on the inboard/outboard engine arrangement. For those with problems, I saw a Gemini 105mc on You Tube where the owner had converted his boat transom to accept a four stroke 40 hp Honda outboard engine for less maintenance issues. I suspect this would adversely affect resale value of he boat. Don't ask me how he made the conversion, but it is there for the viewing for those who may be interested.
