If your perfect boat includes a hull design that slices heavy seas effortlessly with 70% more roll stability and 50% less carbon impact.  Think Aspen.

The C120 (42’6”/12/6 meters LOA) is a breath of fresh air for this size category. She is fast and maintains the much sought after efficiency. She also includes grand sized areas in the salon, staterooms, heads and cockpit. It is the first boat in this category with 600 sq. ft. of deck and living space.

The C120 uses Aspen’s patented award winning hull design for ideal performance with a state of the art Volvo D6. Design cruise speeds are 16-18 kts with a top speed of 20-23 kts, depending on the power (370-435hp). Fuel economy with the single 435 is 10 gph at 16 kts; 50-60% less than competitive boats.

What on earth made you buy a boat made 3259 miles away by a small family company?

My wife, Jan and I have owned boats for years. We started in sailing with an O’Day Daysailer and then a Laser. Graduated to a Hunter and then a beautiful Island Packet 350. Since retiring we have owned two Tiara’s, the latest a Souvran 350 with a quirky IPS. This boat was a bit like a nervous racehorse: when she was good she was great, but on bad days she could be frustrating and infuriating as something would always go wrong. We blew an engine, had leaks in both drives and, unless perfectly tuned, had difficulty getting up on plane. So for a year we had no boat.

Then I read an article on Aspen a newish company out of Burlington, WA. Larry Graf, the owner and designer, had developed a new kind catamaran or rather proa. This means it has two unequal hulls. Larry had designed these boats with the second hull having 65% the displacement of the first hull. They have one engine in the starboard hull and, because of the design, track perfectly straight. This gives great fuel efficiency, incredible interior space and a very modern looking boat. We also liked the two helm seats, the king bed in the master stateroom and the single level for the galley, helm and eating area. Jan did not really want the fly bridge, but somehow I persevered and we had one put on. We have both come to really like the open space with lots of wind blowing in our faces.

I called and got an appointment to visit them at the Miami Boat Show. Now I have to be careful at Boat Shows because once before we went to this show for a dinghy and came away with a new Tiara! Anyway after a visit and a test drive we were hooked and signed up for an Aspen C120. This is a 40’ boat and none had yet been completed. During the next 15 months we visited Burlington on two occasions; once to see the construction and a second time to sea trial a C120.

I must say construction was a little slow for my liking, but we always felt waiting for the quality was worth it. One wonders about how they would deliver the boat to our home in Fort Myers on the west coast of Florida, some 3259 miles away! How will we get warranty work done with no dealers in the state? How will we get it set up after delivery?

Here is what happened. The fly bridge had to be removed so the rig could get under bridges, for the transcontinental journey. A special crib was designed to support it in transit. On arrival in Fort Myers, Aspen flew two expert boat builders east to reassemble the fly bridge and deliver the boat to us in tip top condition. They worked for 4 days to accomplish this. Now being an Economics graduate, I am not outstandingly handy in the engine room and with the details of electrical wiring and such, so we have always had an experienced Engineer/Captain helping us provide good maintenance and regular care. We were delighted to see that our local man struck up a very good relationship with the boat builders from Burlington.

As usual after a few weeks, we had a “punch list” of small issues that needed attention. Most of these were addressed when Larry Graf and his son Nick flew to Florida to give us a full introduction to the boat. This was great and it was in the middle of the heat of a summer in Florida! The boat was now really ready to go!

Subsequently we have had a few further items that needed attention, but have worked out a system with Aspen to call them with issues. They are resolved by their staff and myself and our Engineer/Captain in Fort Myers and the whole exercise is working smoothly and well. This is equally as good as having a dealer locally and in some instances much better as Aspen knows what they are doing.

Now we love the fly bridge and the space. We like the single level for daytime use and the powered dinghy davits, also designed by Larry, are a real joy for us more mature folks. The economy is good, the speed of the displacement hull is a very acceptable 18-20 knots. I am also always amazed by the large wake which always reminds us of the old days of huge fuel bills. We now have the speed at half the cost!

We are contented new owners with a one of a kind boat in Florida! “Rangiora” which is Maori “a perfect day” is living up to her name. Well done Aspen!
