Bayliner 642 Overnighter (2014-) Captain's Report

Bayliner 642 Overnighter

The new Bayliner 642 Overnighter has a LOA of 21’4” (6.53 m), a beam of 8’5” (2.57 m) and a draft of 3'2” (.97 m).

Mission Statement

Bayliner created the 21'4" (6.53 m) 642 Overnighter to provide a small cruiser that can also offer a sheltered cuddy cabin for an occasional overnight. Her amenities make her a capable day boat for family and friends, and she offers not only some versatility, but options that increase her comfort level.

Bayliner 642 Overnighter

Three details that distinguish the Bayliner 642 Overnighter are: 1) its "L-"shaped bench seat in the cockpit; 2) its two, sculpttured skylights in the foredeck; 3) its beam carried well forward creating more interior room.

Major Features

• High windshield increases comfort and seakeeping ability

Bayliner 642 Overnighter

The Bayliner 642 Overnighter becomes an ideal day boat with over nighting capabilities for locations all over the world and has proven herself in European waters both fresh and salt.

Features Inspection

Bayliner has been earning kudos of late and the 642 Overnighter is an example of why. She’s got good looks and functionality that make her an interesting offering. Let’s start with the cockpit since that’s where everyone will be gathered.

Bayliner went with L-shaped seating that utilizes significantly more useful space than the typical bench seat across the stern seen in virtually all cuddy sportboats this size. A sliding forward backrest for the companion seat to port allows switching from a forward facing observer’s seat to an aft facing lounger. This makes her good for sunning, watching the kids paddle around off the stern when anchored or spotting a wakeboarder.

An optional table really makes the scene complete and the helm seat is spaced just right to allow it to swing around and join the meal, or hors d'oeuvres, or whatever.

Bayliner 642 Overnighter

L-shaped seating warps around the cockpit. Notice the base for the optional pedestal table. The port seat is hinged from the front and lifts from the aft end to expose huge storage underneath.

Bayliner 642 Overnighter

Below the port seating is a huge compartment that can be used for all sorts of purposes. There is dedicated storage here for the optional table.

Bayliner 642 Overnighter

With the seat back slid aft, a forward facing observer’s seat is created, and another set of eyes are looking out for traffic. With the seatback forward, the back becomes a reclining chaise for a spotter when towing, or a place for sunning.

Bayliner 642 Overnighter

Ahead of the port side seat is an optional freshwater sink plumed to a 10 gallon (38 L) water tank.

Bayliner 642 Overnighter

An in-deck storage compartment includes a drawer creating a bit more storage than just an open space.

Bayliner 642 Overnighter

An optional pedestal table is expandable to accommodate the amount of people, or food onboard. It also makes moving around the boat easier.

Bayliner 642 Overnighter

The helm is simplistically functional and even includes room for a moving map display. Notice the storage to the side of the helm seat. Wide steps and a grab rail provide a safe transition to the bow.

Bayliner 642 Overnighter

Four-in-one gauges keep the clutter to a minimum. The smaller gauges are fuel, to the left, and depth, to the right. Notice the track for the companionway door which slides under the instrument panel. In the open position, the lower step forms a footrest for the operator.

The Stern and Bow. Of course there are other areas to enjoy on the 642 Overnighter besides the cockpit. A walkthrough to the swim platform is to the starboard side. A nearly full beam sun pad provides the required sunning area and even converts to a chaise lounge. And an optional sun pad for the bow adds yet another place to relax while on a drift, beached, or at anchor.

Bayliner 642 Overnighter

The sun pad is nearly full beam. The starboard seat has insulated storage underneath to double as a large cooler. The stored Bimini can be seen running back from the starboard bulwarks.

Bayliner 642 Overnighter

An idea place for trash or gear storage resides under the seat/step in the cockpit.

Bayliner 642 Overnighter

The sun pad also lifts at one end to form a chaise lounge for sunning.

Bayliner 642 Overnighter

With the sun pad flipped open, a non-skid walkthrough to the swim platform is exposed. Notice the brace underneath that supports the elevated pad.

The three-step reboarding ladder lies flush to the platform.

Cuddy Cabin

And then, of course, there’s the cuddy. This provides a welcome respite from the day's events, whether it be used by the infant needing a much-needed mid-day naptime, or adults overnighting at a distant getaway -- or a place for an afternoon nap at anchor. It also becomes a place to get out of the rain when at anchor.

Sleep Tight.

The cuddy doesn’t provide much more than sleeping space, but for most of us, we don’t need much more than that. There is an optional portable head, which is always a good idea. This cuddy is too small for a galley, but for those who want to cook, why not go for a charcoal or propane grill in the cockpit? It is easy enough to add a rod holder in the aftermarket to hold a grill.

Bayliner 642 Overnighter

Just add a couple of blankets or sleeping bags and the scenario is complete.

Headroom

The 642 has a generous freeboard height forward which not only makes her better at sheadding water in sloppy conditions, it also gives her more headroom in the cuddy. There is 4'4'' (1.32 m) of headroom from deck to overhead, and 3'0'' (0.91 m) of sitting headroom. This means most people can sit upright in the cuddy.

The maximum length of the cushions fore-and-aft is 6'8'' (2.03 m).

Bayliner 642 Overnighter

A Porta-Potti is offered as an option, and for some it’s a necessity.

Notable Options

While well equipped, there are some notable options that we just couldn’t do without -- like camper canvas, for starters. The camper canvas package would greatly increase the overnight capacity allowing the kids to sleep on deck while the parents are nestled in the cuddy. This would of course require the Bimini top option as well, which nearly all owners should seriously consider in any case. Other options are--

Preferred Equipment Package. The preferred equipment package is exactly as the name implies. It’s the most preferred items that anyone would want to have. It includes the snap-in carpet runners, a teak cockpit table, Porta-Potti, and stainless steel trim package. We recommend this package.

Helm Bucket Seat Upgrade. Anytime a helm seat upgrade is offered, go for it. It’s the one seat that gets used regardless of how many people are onboard, and it’s the one that gets the most abuse as well.

Digital Depth Indicator. This should be standard on every boat, in our opinion, even small sportboats like this one.

Portside Sink and Transom Shower. It can never be overstated how valuable running water is on a boat. It allows rinsing off feet covered in beach sand just as easily as a batch of grapes. If the boat is used in saltwater, it's refreshing to rinse off. This option has a portside sink, pressure water, faucet, transom shower.

Engine Upgrade. The standard engine is a 135-hp MPI sterndrive. That will be good enough for most operations, but boaters tend to have a lot of friends, and when loaded with full fuel, full water and the max capacity of people on board, owners will still want some get-up-and-go that the 135 may struggle with. The 220-hp 4.3L engine should keep everyone happy, particularly when towing.

Bayliner 642 Overnighter

With the engine hatch opened, two more storage compartments are revealed that can hold rags, oil, tools…etc. They also provide a good place to dry out wet bathing suits or clothes using the engine heat. Notice the space ahead of the engine allows one to stand at the level of the engine, easing maintenance and daily checks. The automatic fire extinguisher is standard, and this is unusual in this price-point class. Also, look at how the Bimini top stores neatly into position without taking up any additional space.

Handling

Our Bayliner 642 Overnighter test boat was powered by the 220-hp Mercury MerCruiser 4.3L MPI V6 gas engine driving an Alpha One sterndrive with a 14.25 X 21P three blade aluminum prop. Handling was solid around the dock with the 642 Overnighter responding quickly and nimbly to gentle and moderate steering and throttle. The ride through the intermittent chop and large wakes we encountered during our test was pretty much what one would expect. Turns were smooth and when hard over at cruise, the speed loss was normal for this type and size boat, requiring just a little bump up of the throttle.

The throttle was well positioned for making small accurate adjustments at speed. When recording our time to plan and 0 to 30 mph bow rise spiked briefly at 23-degrees which seems like a lot, but we never lost sight of the horizon in front. Her cruising angle was 5-degrees, just where it should be.

Performance

We recorded an average top speed of 42.9 mph at 5000 rpm. Best cruise came in at 26.1 mph at 3000 rpm while burning 8.8 gph giving us a range of 112 statute miles.

Hole Shots. Her average time to plane was 6.7 seconds, 7.6 seconds to 20 mph and from 0 to 30 mph was 11.3 seconds.

At 6’3'' (1.91 m) my sight lines through the windscreen were good at all speeds while seated and with the bolster up. The range of travel for the helm seat was excellent allowing for it to be well out of the way when driving while standing.

Observations

European boaters have had access to the Bayliner 642 and have liked its advantages. Now, Bayliner is bringing the 642 Overnighter to the U.S. She allows for expanding the usefulness of a small runabout while still staying in the entry-level size range that anyone can handle. She comes with a limited lifetime transferrable hull warranty and a 5-year deck warranty. The engine comes with MerCruiser’s 2-year warranty.

Old timers will remember the day when virtually all sportboats were cuddy designs. Then the bowrider appeared and the world moved to this concept. Today only about 5% of the sportboats sold are cuddys. But they have their advantages--

First, They Look Cool. To our eye, well-designed sportboats are like sport cars on the water. Another way to view them is like mini high-performance boats.

The covered foredeck with windshield makes cuddys much more seaworthy offshore than bowriders which can easily ship water in rough conditions; however, this is virtually never a problem for bowriders in the protected water where nearly all of them reside. Certainly the Bayliner 642 Overnighter is capable of cruising around bodies of water such as Long Island Sound and the Chesapeake Bay.

With a Bimini overhead and buttoned up with a cruising canvas, they make a dry, cozy environment on a rainy or chilly day. As already pointed out, in this mode they can also sleep four people. (Caveat: Successful sleeping aboard any boat this size has more to do with how rolly the conditions are more than anything else.)

Cuddys are ideal for traveling in rivers and canals as found in Europe and in many places around the world during the day, then tying up at night to spend the evening eating and sleeping ashore. This provides the best of both worlds and is a fun thing to do on a budget.

Finally, with a tow line a cuddy becomes a towing vessel for waterskiers and wakeboarders just as well as a bowrider. While the cuddy does not have a long storage compartment in the cockpit sole, it does have the forward cabin which can also serves as a huge storage compartment.

The Bayliner 642 Overnighter can also be a watersports platform in addition to a cruising boat.
