2004 Silverton 34 Convertible, 37'7" LOA, in Saint Petersburg, Florida, in Pinellas County on the Tampa Bay side of the Intracoastal Waterway. Twin Crusader 8.1L MPI gasoline inboards, 750 hp total, approximately 850 hours. Two staterooms, split head, enclosed flybridge helm with an all new Garmin electronics suite, and a fishing cockpit with a transom dive door. What separates this one from the rest of the 34 Convertibles on the market is the history: lift kept for most of its life, which is uncommon on a 2000s convertible in Florida, with fresh bottom paint in excellent condition and more than $80,000 in documented maintenance and upgrades over the past four years, receipts available.

GREAT LOOP NUMBERS: AIR DRAFT, DRAFT AND LENGTH

Three published numbers decide whether a boat can run America's Great Loop, and the 2004 Silverton 34 Convertible clears all three with margin. Published bridge clearance is 12'7", against the 19'6" controlling height at the Chicago Sanitary and Ship Canal, which is the lowest fixed bridge on the route. Published draft is 3'3", against the 5' maximum on Canada's Heritage Canals and the Trent-Severn Waterway, where 4' or less is preferred. LOA is 37'7", inside the 42' most Loop marinas can take and well inside the 90' Trent-Severn limit. Buyers should confirm actual air draft with the radar arch and antennas installed, since 12'7" is the builder's figure for the model.

WHY THE LAYOUT WORKS FOR LOOPING

The 2004 Silverton 34 Convertible carries a 13'10" beam, which is wide for a 37-footer and is where the two-stateroom layout comes from. The master forward has an angled double berth. The guest cabin has over and under berths. The head is a split design with the shower in its own compartment, so two couples are not sharing one wet space for six months. The salon has an L-shaped dinette, a sleeper sofa, air conditioning and heat, and hardwood flooring in the galley. Walkaround bow access and wide side decks matter more on the Loop than they do anywhere else, because 100-plus locks mean crew working lines from the deck rather than from a cockpit.

ALL NEW GARMIN ELECTRONICS

The flybridge helm on this 2004 Silverton 34 Convertible was refitted with a complete Garmin package. The chartplotter is a Garmin GPSMAP 8612, a 12 inch display that ships with Garmin Navionics+ cartography, paired with a Garmin autopilot and a Garmin VHF. Faria analog gauges, a digital hour meter and a compass round out the helm, all under new canvas and a full window enclosure. Guest seating on the bridge is a U-shaped settee. A 12 inch plotter running current charts is worth more on a Great Loop run than on almost any other kind of cruising, because the route crosses coastal, inland river and Canadian canal cartography inside a single season.

POWER, FUEL AND RUNNING GEAR

The 2004 Silverton 34 Convertible is powered by twin Crusader 8.1L MPI gasoline inboards, 750 hp total, with approximately 850 hours. Fuel capacity is 286 gallons, water 94 gallons, holding 37 gallons. The powerboat guide for this model lists cruising speeds of 16 to 18 knots and top speeds in the mid-20s on the standard 330 hp package. Gasoline is worth naming as a Loop consideration rather than a drawback: every fuel dock on the route sells gas, while diesel is not available at all of them, and gas engine work is easier to find in the small river towns between Chicago and Mobile.

2026 UPGRADES

The following were new to this 2004 Silverton 34 Convertible in 2026, per the owner: the complete Garmin electronics package described above, Glendinning electronic engine controls, port and starboard raw water pumps, aft lighting, five batteries, a new battery charger, and a Fusion stereo. The owner states the Glendinning controls alone were a $16,000 installation and the autopilot $5,500. New canvas and a full helm window enclosure are also recent, along with upgraded captain's chairs on the flybridge, with the original chairs included.

GALLEY, SALON AND COCKPIT

The galley on this 2004 Silverton 34 Convertible has a full-size refrigerator and freezer, a two-burner electric cooktop, a convection oven, a deep sink, under-cabinet lighting, and dedicated counter outlets. The salon has crescent seating with a custom adjustable table, the original table included, a flat screen television, blinds, and engine room access. The cockpit has a swim platform with ladder, a transom dive door, an in-deck fish box, a large transom storage compartment, stainless cleats and grab rails, a raw water washdown, and stairs to the flybridge. A bridge overhang shades the forward cockpit.

HULL AND BOTTOM

The 2004 Silverton 34 Convertible is a modified-V fiberglass hull with 12 degrees of deadrise at the transom and a published dry weight of 18,550 pounds. Twelve degrees is a cruising hull rather than an offshore deep-V, which suits the protected rivers, canals and bays that make up most of the Great Loop. Bottom paint is recent and in excellent condition. Lift kept for most of its life.
