Brief Summary

The newly-launched Tiara 4300 Open was designed to replace the hugely popular 4200 Open and serve as a response to customer feedback. Some significant design changes were made to the layout, and some others were carried over from the old 4200 to this model. The bottom line is a (slightly) bigger and (very much) better yacht. Given her fast-paced boat show schedule, current images aren’t even available on this boat yet, and won’t be until about the middle of next month, but until they are, we wanted to point out some of the features that are new and unique to this boat.

    Tiara 4300 Open (2010-) Line Drawing


    Captain's Report

    Tiara 4300 Open
    Over half of the 4300's length consists of outside space, just what you want in a multi-use boat. Who wants to sit below decks on a beautiful day, anyhow? If you don’t want to fish, a swim platform is optional ($5,680 for a 42” model).

    Swiss Army Knife

    The Tiara’s big cockpit is ideal for not only fishing, but also diving, a swim party, an evening cocktail party, sun bathing, and just plain old hanging out. The raised bridge deck provides a comfortable, roomy helm station with excellent sight lines all around the boat, especially helpful in docking and close-quarters maneuvers, but with easy access to the deck and cockpit; add a hardtop and enclosure and you have a rainy-day pilothouse. Over a decade ago the folks at Tiara realized that not all of the people buying their express fishboats were gung-ho fishermen. Many were just boaters who wanted an express boat, but didn't want one that looked like an over-sized sportboat. These were customers who wanted set themselves apart from the beer and pizza set, preferring instead a model and brand that was more closely associated with the salty aspects of cruising offshore. Many Tiara owners used their boats as floating condos or weekend summer retreats. Years ago Tiara started obliging by putting fold out seats in the cockpit, thus turning it in to large outdoor entertaining area. Even if you don't know a ballyhoo from a balaclava, a express-style boat like the Tiara 4300 is probably just what you need. It’s a Swiss Army Knife of boats, and now we are seeing many other builders following the same strategy.

    Fish boxes or storage bins, depending on how you want to use the boat. You can't see the 24"x24" aluminum backing plate for a fighting chair molded into the cockpit sole, but it is there just in case.

    Live Al Fresco

    The lower cockpit is 95 sq. ft., ample for all kinds of activities. Tiara includes a transom door, coaming bolsters, fresh- and raw-water washdowns and insulated under-sole boxes as standard; the lid for each box is divided in half for easier access. The bridge deck provides another 98 sq. ft. of al fresco space, equipped with the usual furniture you'll find on a boat of this type. There is a wet bar, and a TV jack behind the helm seat if you can't live without the box. (A 32" Sharp Aquos in the dinette area below decks is standard.) Engine access is via a hatch in this area.

    Tiara 4300 Open
    The 4300 even has a mezzanine, just like a sportfishing convertible – an ideal place for a couple of folks to kick back and watch the action, whatever it may be. There's a cooler under the seat, stowage under the step. This boat has the Tournament hardtop, with rod holders and rocket launcher.

    The swivel seat on the L-lounge – it becomes a forward-facing companion helm seat. The hardtop is optional, but we can’t imagine the boat without one.


    Tiara builds the 4300 Open using vacuum bag injection molding to ensure excellent laminate bonding; both hull and deck are balsa-cored. Instead of polyester, Tiara uses a high-profile AME 6000 vinylester resin in the hull; it’s strong and flexible, and less prone to water absorption than polyester resin. We think lots of 4300s will end up in warm climates, where they’ll stay in the water year ‘round, so that’s important. Osmosis is more likely in warm water, and when boats swim for extended periods. Vinylester stops any water migration through the laminate, so with the Tiara 4300 you don't have to worry.There’s a five-year transferable warranty on hull, deck and fiberglass fuel tank, two years on accessories. Many boats in this class have aluminum fuel tanks which can rust if they sit in bilge water or water drips or drains on top of them. Fiberglass tanks are not cheap nor are they easy to install, but they are the best way to go.

    Tiara 4300 Open
    That mezzanine looks pretty comfortable to us. The black panel on the foredeck is an acrylic skylight.

    The Cabin We Need

    Like most express fishboat cabins, the 4300’s is fine for the cruising most of us do – short trips of a few days a couple times a year – you can live without a salon for that long, especially in the summer. Thanks to the boat’s 43'3” overall length (45'11” including the molded pulpit) and 15’4” beam, there’s lots of room below decks.

    Tiara 4300 Open
    There’s no salon in a boat like this one; the bridge deck doubles as a gathering place. But the 4300 has room enough below for a spacious dinette and excellent galley. Teak joinery is standard.

    There are two staterooms, a master forward with pedestal queen berth, and a guest cabin with upper and lower berths. This arrangement makes the boat ideal for a family with kids, or two couples willing to flip for the queen. There is one head, which is all you need on a boat this size, to our way of thinking. Adding a second head is going to take valuable space out of the dinette or galley.

    Tiara 4300 Open
    If you need more sleeping space, the dinette converts to a double; the backrest becomes a Pullman berth, too.

    The galley has a 2-burner electric cooktop and a microwave oven, Vitifrigo dual refrigerator/freezer drawers, but no icemaker; you can get one as an option ($940) – it fits in the freezer drawer.

    Simple but adequate, the master has stowage under the berth and in port and starboard hullside cabinets. A 19” Sharp Aquos TV is standard, as is Marine Air Systems A.C.


    Standard power is a pair of 715-hp Cummins QSM11 diesels. We haven't tested the boat, but according to Tiara the Cummins produce a top speed of 35 knots, and cruise around 30 knots. These are straight-shaft engines; if you want something more exotic (and more expensive), check out the Tiara 4300 Sovran, with IPS drives.An Onan 9.0-kW genset is also standard, as is most other mechanical stuff you’ll need, including a windlass. Trolling valves are a $7,910 option, but they will come in real handy at times; ditto a bow thruster ($8,790).

    Tiara 4300 Open
    A clean, well-lighted space for the two big Cummins and the Onan genset. This is typical Tiara quality – everything neat as a pin and easy to access.

    So Where Does the Fishing Come In?

    The Tiara 4300 Open's MSRP of $907,990 includes just about everything you need for boating, but very little piscatorial gear. However, there's enough on the options list to satisfy any modern-day Izaak Walton. How about a tournament hardtop with rocket launcher and side rod holders ($33,780)? Rupp 30' outriggers ($10,890)? Rod stowage under the queen berth in the master stateroom ($290) and dinette ($450)? A macerator for the cockpit-sole lockers, turning them into bona fide fishboxes ($760)? Tiara will even add teaser reels if you must have them ($11,640).

    Tiara 4300 Open
    Rod stowage under the queen berth is optional, and under the dinette, too.


    A few minutes on the calculator and you'll see that a well-equipped, fishable Tiara 4300 will run close to a million bucks, MSRP, once you add electronics, but that's not out of line for a tournament-ready sportfisherman this size, and of this quality. You can spend more and get less than Tiara packs into the 4300. If you buy the cruising version you'll save money. On the other hand, a lot of cruising express boats look about the same and cost a lot less. Why?We once attended a Tiara owners' rendezvous and at lunch one owner asked the other five Tiara owners sitting at his table, why its boats cost so much compared to other brands. "They have the same engines and equipment as the others, but cost 15% more." he said. "Why do we pay it," he asked. The table was quiet except for the rolling eyeballs. What the other five folks were silently saying is that after owning a Tiara, if you have to ask that question you are not paying attention.You don't find many newbies buying Tiara yachts. It is not for nothing that Tiara owners are virtually all veteran boaters, many of whom are on their 10th or 12th boat. Most have been around long enough to know that if you want a premium yacht and a first-class boating experience, you will gladly pay a premium price to get it. To these people, the alternatives are simply not worth the money saved. Life is too short not to do it right when you can afford it.
