Fiberglass/Reinforced
"Here And Now" is one of the finest examples of a well Maintained 1998 4100 Tiara Open. Including much desired options such as her freshly overhauled CAT 3208 435hp engine package, New Generator, New AC Units, full Garmin electronics suite and the very popular factory hardtop to name a few, this amazing yacht is turn key ready to go!
The Tiara 4100 Open is a big offshore express whose lasting appeal says much about her versatile personality. Part luxury cruiser and part hardcore fishing machine, the 4100 is a very roomy boat thanks to a wide 14'8" beam. Below decks, her spacious interior features a full-service galley, Leather dinette, private master stateroom, and a large head with a separate shower stall. The dinette converts to a double berth and the backrest lifts to create a single Pullman berth. A teak-and-holly cabin sole, Corian galley counter, and wine cooler. Topside, a deluxe wet bar with ice maker is aft of the helm, and the cockpit-three steps down from the bridge deck-you'll find a circulating livewell, bait prep center, in-deck fish box (with macerator), freezer, and transom door. There's also a foldaway rear bench seat for evening cruises. An access hatch to the engine room in the bridge deck sole provides quick sight checks while underway. .
