Captain's Report

Key West 351 CC
The 351CC is the biggest boat in Key West’s Billistic line, and with graphics like these, the boat’s intention is pretty clear. She’s built to go after billfish. She has an LOA of 34’10” (10.6m) and a 10’ (3m) beam.

Mission Statement

Key West’s approach with its flagship 351CC was to develop a fishing-first center console with creature comforts. She comes standard with a windlass, trim tabs with indicators, an 18-gallon freshwater system, a porcelain toilet, and a hardtop with LED lighting and a powder-coated frame.

To get the boat offshore to go after big fish, Key West suggests triple outboards up to 900-hp, so long as they are not V-8 motors on the 351CC because of their width and weight.

Key West 351 CC
The 315CC has plenty of deck space for anglers to move about freely while fighting fish.

Major Features

  • •A windlass
  • •Auto-retracting trim tabs with position indicators
  • •Flush folding aft bench seat
  • •Leaning post tackle station with tackle storage, a livewell, a freshwater sink, a prep area, battery storage, and a fire extinguisher
  • •A private head in the console with a porcelain toilet and SeaDeck flooring
  • •A hardtop with LED lighting, spreader lights, and powder-coated framework

The massive helm console has ample real estate for nav screens, fish finders, and most everything else needed. Note the ergonomically correct control lever placement at a low angle -- something we rarely see.

The aft bench seat folds inboard from the stern to provide space for two people.

Key West has positioned the head as deep in the boat as possible for max headroom. Note the storage drawers and four rod holders.

The standard hardtop comes with LED and spreader lights, and the powder-coated frame provides natural handholds.

Features Inspection

The Stern. Taking a closer look at the 351CC, the easiest way to board from the docks is to step on at the platform forward of the motors and enter the cockpit from the gated passageway aft to port. There’s a boarding ladder aft. In the cockpit, there are the aforementioned aft bench seat and coaming pads that extend all the way to the bow. Directly abaft the seat is an insulated fish box. Outboard to starboard is a 40-gallon (151.4-liter) livewell with an acrylic hatch.

Key West 351 CC
With the aft bench seat stowed, the cockpit is open for fishing. The hatch in sole directly ahead provides access to livewell pumps and other equipment. The passage to the stern is to port and it closes with a gate.
Key West 351 CC
Abaft the bench seat is a fish box with a small upper compartment. Its hatch, like all those on board, is held up with a stainless-steel gas strut.

The livewell is in the aft starboard corner. The gas strut lets anglers use two hands to retrieve bait.

The Leaning Post. The aft side of the leaning post has a well-organized tackle and prep station with a freshwater sink and 28-gallon (106-liter) livewell beneath separate hatches up top and drawers and tacklebox slots down low. There are fishing line spools on the inside of the door. Key West installs the batteries in the bottom of this locker. The front side has two seats with fold-up bolsters and armrests and a glovebox in the base.

The upper section of the leaning post “convenience center,” as Key West calls it, has a sink and drop-in cooler.

Down low, anglers will appreciate these drawers and tackle slots that should help keep things organized.

The Helm. Key West placed the tilt helm and Edson stainless-steel steering wheel with spinner knob as far to port as possible, which creates plenty of space for the driver and companion to travel side-by-side. The forward-most vertical section of the dash has space for two 15” (38 cm) chartplotters.>/p>

Ahead of the starboard seat, the dash has two 12-volt plugs just below two stainless-steel cup holders. This would be a good spot to plug in cell phones. To facilitate rigging the helm and adding electronics, the entire panel pulls aft on hinges.

Key West 351 CC
Twin Simrad chartplotters are in clear view and will provide all the navigation and fish-finding information the driver could need.

Technicians will appreciate that the whole dash folds aft to provide access to the dash rigging.

The Console. Entry to the head is through a hatch in the port passageway and there’s a screened portlight to starboard. Because the head is positioned so deep in the hull, there’s more than enough seated headroom for an average adult. Underfoot, Key West uses SeaDeck faux teak in the head. Drawers provide additional gear and tackle storage, and there are four racks for fishing rods or landing tackle.

Key West 351 CC
All the pumps for the toilet and shower are easily accessed in this locker.

Gunwale Storage. Making good use of available space, Key West puts open rod racks and secure lockers in the gunwale on each side of the 351CC. Forward in the bow outboard on each side are open trays with retainers that should be tall enough to contain docklines and three stainless-steel cup holders on each side.

Key West 351 CC
Three rods can be secured in each gunwale, and there’s locking storage in the gunwale compartment.

The Bow. It could be said that on the 351CC, the cockpit abaft the console is for fishing, and the bow is for relaxing or cruising. There are side-by-side bucket seats on the forward side of the console with cup holders in the center armrest. Beneath the bottom cushion is an insulated cooler that drains overboard. Forward in the bow, there are lounges with backrests that fold out of the gunwales. Outboard of the lounge on each side are storage trays with three cup holders.

The front of the console has seating for two, and the base is an insulated cooler that drains overboard. The twin seats with cup holders between is something we rarely see forward of the console.

The bow has backrests that fold out from the gunwales, so passengers can sit forward facing and stretch out.

Three cup holders on each side of the boat ensure that everyone will have a place to set his or her drink.

Bow Storage. In addition to the trays outboard on each side, the 351CC has insulated lockers in the bow sole that can be used as coolers or for dry storage. In the foredeck, there’s a compartment that Key West designates for fender storage aft of the anchor locker that contains the standard windlass.

Key West 351 CC
The fender storage box is aft of the anchor locker in the 351CC’s deck. This is a good idea and is something we rarely see on any boat in class and type.

Construction. Key West builds the 351CC with a solid fiberglass bottom and foam coring in the hullsides and deck. The transom is cored with composite, and an aluminum plate is fiberglassed into the transom to provide additional support for the multiple outboards.

The hull and deck are attached in a shoebox-lid-style joint that is bonded with 3M 5200 and through-bolted. Stringers are molded as a one-piece grid outside the boat and then bonded in place and foam filled. Aluminum plates also back up all deck hardware.

After the white gelcoat is sprayed in, the skin coat is applied. It’s followed by layers of fiberglass and resin all rolled by hand.

The stringers, bulkheads, and transverse supports are part of a single grid that is formed outside the boat and then bonded in place.

Once the stringers are bonded in place in the hull, they are filled with flotation foam.
Key West 351 CC
Before the hull and deck are joined this adhesive is applied to the stringers. It helps bond the two halves of the boat.

The hull-to-deck joint is sealed with 3M 5200, and notice the holes for the mechanical fasteners that follow.

Power and Performance

The 351CC has a single step bottom and is rated for a maximum of 1,050-hp in a triple-outboard configuration. Twin engines would have 25” (63.5cm) shafts and triples would have 30” (76.2cm) shafts.

We haven’t tested the boat, but Yamaha did and produced a Performance Bulletin on the 351CC with triple 300-hp F300 4-stroke outboards and a test weight of 12,419 lbs. (5,639 kg).

The engines turned 15” (38cm) x 20” (50.8cm) (port and starboard) Saltwater Series II propellers and a 15” (38cm) x 21” (53.3cm) (center) Saltwater Series HS54 prop through 1.75:1 gear reductions. According to Yamaha, at wide-open throttle at 6050 rpm, the 351CC hit 61.6 mph and burned 79.0 gph, giving the boat a range of 228 miles. Best cruise was at 3000 rpm, where the boat ran 27.5 mph and burned 19.8 gph, resulting in a range of 407.8 miles. In acceleration tests, the boat ran to 30 mph in 4.55 seconds, according to the Yamaha techs.

The 351CC has a deadrise of 24 degrees at the transom and tops 60 mph with triple 300-hp Yamaha outboards.

    The 351CC follows a trend we’re seeing in center consoles with a comprehensive list of standard equipment that simplifies the buying process. It makes sense because most of these items are options that we think most owners would order anyway, such as a windlass, trim tabs, and the hardtop.

    Looking at the 351CC’s hull design, it has a noticeable Carolina flair and a deep bow entry that tells us Key West intends for users to take this boat offshore. Serious anglers might be concerned about the ability to boat large fish. There is a small transom door aft to port, but a larger side door would be a welcome option.

    Key West is known to be a “value” brand, but it has pulled out all of the stops with the 351CC. It is full of useful design innovations, and we find the execution impressive for the price.
