Like new Cobia 220 CC for sale.&nbsp; Only 30 hours on it and in great shape.&nbsp; Has a 200 yam and most options that were available.&nbsp; Has a Garmin echoMAP CHIRP 94sv.&nbsp; Reason for selling: my wife gets seasick and we have only put it in the water one time this year.&nbsp;&nbsp;
&nbsp;
What makes the 220 CC so great? Maybe it’s the sharp forward entry, large bow flare and variable deadrise hull that makes it ride better than a lot of bigger boats. Or it could be the high sides and deep interior freeboard that make it feel so secure and safe even in outsized seas. Then there’s the fact that it has an insulated fishbox that drains overboard and undergunwale rod storage, features that other boats its size can’t claim. And what about the hidden rear seat with flip up backrest and battery storage underneath? Put it all together and the 220 CC is the most feature rich and big water ready 22 footer out there.

The newly launched 26-metre Contest&nbsp;85CS clearly demonstrates the strengths&nbsp;in Contest Yachts’ long-term collaboration&nbsp;with world class designers judel/vrolijk&nbsp;&amp; co and Wetzels Brown Partners.Designed for fast passage with&nbsp;powerful, practical, deep-ocean cruising&nbsp;capability, the Contest 85CS is easily&nbsp;sailed, managed and maintained by&nbsp;short-handed crew, and perfectly set&nbsp;both to sail the world and enjoy&nbsp;sailing’s high society.The hull and deck-form of the Contest 85CS&nbsp;show the reasoned approach of a design team&nbsp;referenced across every level of performance&nbsp;cruising and racing, from family adventuring&nbsp;to grand prix eventing. This brings a moderate,&nbsp;shallow underbody running back from near&nbsp;plumb bow, with integral bowsprit and&nbsp;optional furler for asymmetrics, to a soft-chined, broad stern. Sailing flat and fast she&nbsp;has a single rudder for precise and powerful&nbsp;yet light control at the twin helm stations.The composite construction is Lloyds’ certified&nbsp;and includes a sandwich laminate throughout from sheerline to keel stub, with advanced&nbsp;single-shot vacuum infusion for each of hull, structural grid and then deck. The keel is of&nbsp;stainless steel and lead for performance profile with cruising draft. The rudder is&nbsp;carbon for performance and keeping weight out of the stern to allow for good stowage in&nbsp;the large lazarette which has a hydraulically operated transom garage and beach platform.&nbsp;Space is such that the RIB can be stowed with outboard still in place.&nbsp;The low, sleek styling of the saloon coachroof&nbsp;sits well with the sweet sheerline profie and wide expanse of laid teak decking. Flush decks&nbsp;are standard and hardware is according to intended sailing. For some that means&nbsp;all-carbon, for others a more conventional&nbsp;approach. All enjoy the top line specification&nbsp;for which Contest yachts are so well known&nbsp;and which makes handling and operation&nbsp;safe, secure and satisfying. Nothing is left to&nbsp;chance. It’s all to the point and fine-tuned for&nbsp;personal goals.Simply put, the Contest 85CS has perhaps the widest cabin plan options in any yacht this size, and the making of this interior sensibly begins with practicality at sea. You’ll see this in the arrangement of furnishings and walkways with handholds and support always within reach. It is in the easy access always given to service and maintenance of all onboard services and systems. It is in the very fabric of the yacht from the way in which safety systems are incorporated and operated, right through to the finished surface materials, be it in the impeccably hand-crafted timber work or upholstery. And completing the picture the entire interior is wonderfully bright with extensive panoramic outlook to saloon and multiple hull windows and hatches in the cabins. Dutch heritage and modern technology ensure

Very nice 1997 Chaparral 310 Signature Cruiser.
Twin Mercruiser 383 Mag Strokers with 94 hours. These motors will get you on plane in just a few seconds. The engines were installed in July of 2017 at Sunrise Marine in San Pedro, California. Including the engines, over $38K in maintenance and updates.&nbsp;
Bottom and outdrives done in October 2020. New Bennett trim tabs installed.&nbsp;
Her layout is perfect for entertaining!! Sleeps up to 5 comfortably. Ideal for a family trip to Catalina or taking a client out to close the deal. This boat does not disappoint!!
Keeping her beautiful is a full canvas and Isenglass enclosure with snap in carpeting.&nbsp;
Much of the interior has been recently updated. All memory foam cushions/mattresses.&nbsp;
A/C and heater work great!! Just right for those hot August nights or for those cold rainy days when it's only the two of you.&nbsp;
Refrigerator is roomy and easily holds your favorite bottle of Champagne or Chardonnay. It also keeps Coronas and IPA's at the perfect temp and all the while, it still has room for sodas and water. The microwave is great for popcorn and the TV with build in DVD player is great for the kids.&nbsp;
Fabulous updated "Push Button" toilet!! No pumping...Besides, nobody likes to walk all the way to the Marina bathrooms at 3:00 in the morning.&nbsp;
We have agonized over the decision to let her go. The memories we have will always be treasured. We have reached out and practically touched a dolphin. We have glimpsed a green flash at sunset a few miles offshore.
Now, our lives are taking us in a new direction. This amazing boat deserves a new owner to bring joy and happiness to. She is turn key and ready for her next adventure with you.&nbsp; &nbsp;
