    Captain's Report

    Tested by Capt. Brandon DeNataleWhat do you get when you combine the sleek stylish lines of a sportboat with the feature packed accommodations of a deckboat? A perfect marriage of form and function, that is, the new Maxum 2100 Sport Deck. With the gaining popularity in this category I am always excited to see how each manufacturer goes about setting their product apart from the rest. After eyeing Maxum’s 2100 from the dock I knew there was something to get excited about.The 2100 Sport Deck is a sharp looking boat, which measures in at 23 feet 2 inches with the swim platform. The beam is a narrow 8 feet 6 inches, but the beam forward design helps keep the cockpit open without taking away from the sporty lines. Whether you’re a watersports enthusiast or a sun worshiper, everyone will enjoy what this boat has to offer.BowUp in the bow we find one of the most defining features of a deckboat, the large open bow. Concealed below a large hatch is a convenient ladder that enables you to board from the bow of the boat when pulled up to your favorite beach. There’s also storage for your anchor and line and a freshwater shower to get the sand off when leaving the beach. Moving into the seating area there’s room for four adults or recliners for two with comfortable backrests. Well placed throughout this area are four-cup holders for beverages and four handholds for safety. And if you’d rather lay back and catch some sun, there’s a filler cushion that fits into this area and turns it into a giant sun pad. And when you’re ready to relax and enjoy a game of cards or a light lunch, there’s also a removable table that fits up here and provides the perfect atmosphere. FeaturesThe walk-through windshield leading into the cockpit is wide and provides easy passage. A partition here easily opens and locks into place closing the lower section of the walk-thru. This is one of the most under-rated features, as it will dramatically reduce the breeze coming into the cockpit on those early chilly morning runs. There’s a compartment to starboard where you’ll find a removable cooler and plenty of storage space for loose items such as fenders and life jackets. Over to port built into the companion console is the entrance to the porta-potti. There’s sufficient space here for privacy while changing and plenty of ventilation. In the middle of the walk-thru is a large ski locker that opens on gas struts to reveal plenty of space to store several pairs of skis and wakeboards. I really like this feature since I always have several people that bring their own skis and equipment. This allows you to store them all away and avoid cluttering up the cockpit. Behind the HelmThe helm on the 2100 is ergonomic and everything is right where it should be. All instrumentation is placed high and easily within sight of the driver. The switches and radio control, and tilt control are to the left and right of the wheel. They’re out of the way, but reachable when needed. Controls for the MerCruiser power plant are located to starboard and are responsive and comfortable to use. The helm has bucket seats with a large flip-up bolster. I really found this to be comfortable and used the bolster most of the time since I enjoyed having an unobstructed view over the windshield while underway and docking. Over at the copilot station the same flip-up bolster provides seating for your companion and there’s also a handhold here and a small refreshment center with sink up on the dash. Cockpit LayoutThe cockpit right behind the helm seats is wide open and makes getting around the boat very easy. The seating back here is comprised of an L-shaped arrangement. The gunwale is high, featuring soft cushions for comfort and handholds for safety. The seating along the port side features storage below for supplies and the seating along the center transom provides access to the engine. With the addition of the removable table back here you can entertain all your guests in style and comfort. Over to starboard, the corner bench seat removes to give you access to the walk-thru. Simply remove the seat and store it in one of the large storage compartments for the day and you can freely move from the cockpit to the stern without having to climb over seats or get the whole cockpit wet. In the walk-through there is another freshwater shower that is perfectly placed to rinse off after a long day of skiing. Our boat also had the extended swim platform, which I think is a must have for anyone that’s planning on spending any amount of time in the water. It adds over 2 feet to the swim platform and is perfect for getting your gear on or just for sitting and enjoying the day. You will also find a stereo remote tuner back here so you can change the channel without ever having to take your feet out of the water. An expandable swim ladder and strategically placed handhold make getting out of the water a cinch. Engine AccessThe engine compartment is easy to get to at a moments notice. Simply lift the handle and the whole rear transom seat and back lift on gas struts. Our test boat was equipped with a 220-hp MerCruiser 5.0Liter engine with Alpha One drive. There is good amount of space to perform maintenance around the engine. And general access is what you would expect of a sport boat. SpecsThe 2100 Sport Deck measures in at 23 feet 2 inches long and 8 feet 6 inches wide, making it easy to trailer with a weight of 3,928 pounds. She carries 56 gallons of fuel in her tanks and the hull features 20 degrees of deadrise in the stern, which helps add to the smooth comfortable ride. PerformanceOut on the water I really got a sense that this is a solid boat. Maxum is known for their quality work and it shows not only in the finished product, but in the company’s transferable five-year structural deck and hull warranty given to every boat. The handling was very good especially at high speeds. Turning was quick and the unique stepped hull really helped her get up and on plane quick in 5.1 seconds. This will come in handy when getting someone out of the water. Cruise speed was found to be 32.4 mph at 3500 rpms. At this speed you can expect to cover a little over 150 miles between fuel stops. Top speed was found to be 41.9 mph at 4600 rpms. I’m really impressed with this boat for its versatility and performance. Whether you’re looking for a sportboat with enough room for the whole family, a ski boat with enough power or just the perfect boat for enjoying a day on the water the 2100 Sport Deck seems to do them all.
