The 42/5 designation means that this boat can stretch itself from 42 feet in length overall to 45 feet at the touch of a button.

Bigger isn't always better. For instance, did you ever wish your boat was a few feet shorter when you were backing into a tight dock space?

One unique feature sets the new Sealine F-42/5 Flybridge apart from anything else on the water: It's the boat's ability to make itself shorter or longer as deck space is needed. The 42/5 designation means that this boat can stretch itself from 42 feet in length overall to 45 feet at the touch of a button — with the Sealine Extending Cockpit System.

The F-42/5 can extend its cockpit deck an additional 3 feet to expand the space while docked or at anchor. An electrically operated section of decking moves out from under the saloon floor and extends beyond the edge of the swim platform. The transom bench seat moves out with it, so there's more deck area for table and chairs. When the party's over, just push a button, and the extension retracts.

Join the Party

The cockpit area of the F-42/5 is the focal point for the boat's topside entertainment and activity. A wet bar, plus refrigerator and barbecue options, offers welcome convenience for alfresco dining.

The adjacent swim platform is an ideal jumping off area for watersports, not to mention a storage spot for a tender or a PWC. Either can be launched using the optional passarelle.

There's a considerable amount of storage close at hand in the cockpit, for all activities. The lazarette, below, can accommodate large items, and a number of smaller storage lockers are located along the sides.

Even more storage is provided inside the flybridge overhang, which also provides shade for the cockpit. It has a pair of drop-down storage bins: One is made to hold the optional canvas cockpit enclosure when it's not in use; the other takes smaller items, such as PFDs.

Your on-deck party guests can circulate all the way up the stairway to the flybridge, where you'll find an L-shaped lounge that will comfortably seat six people. Two more guests can sit facing forward when sections of the sunpad are lifted to form backrests. And, of course, the captain and first mate can swivel their double helm seat to join in the conversation around a removable table (when the boat's not under way).

When you don't want to take full advantage of the large sunpad, you can shade the flybridge with the optional Bimini top.

Step inside the F-42/5 saloon, and you'll find yourself in another world. The saloon is spacious, yet cozy. The woods and fabrics provide a sensual and comfortable surrounding.

A nearly 360 degree panorama of glass allows natural light to flood the area. You can let the breezes in, as well, thanks to electrically operated windows on either side of the saloon.

Aft and to starboard, a U-shaped seating and dining area is situated around an adjustable-size table. At night, it can convert to a double berth.

On the opposite side, in the aft corner, there's an entertainment center and a wet bar — and forward of that, you'll find enough space for a pair of club chairs.

The galley is one step down from the saloon deck, to port. It has all the appliances you'll need for cooking anything from an elegant formal dinner to a simple snack — including a double-burner stove, a convection/microwave oven, a dual voltage refrigerator and a double-basin stainless steel sink. All are set around a spacious countertop.

There's storage both above and below the countertop, and a unique modular bin system is built-in under the sole.

Get Comfortable

The F-42/5 has two suites with separate heads, for the ultimate in privacy and convenience.

The midcabin offers several configuration possibilities. You can use a section of one of the berths for seating and the other for sleeping; use both sections as single berths; or convert the entire space into one large berth. The cabin also contains a hanging locker and a dressing table with a lighted mirror. If you like, the boat can be ordered with the midcabin space configured as an office instead.

Both heads have generous countertops with basins and dressing mirrors on the backs of the doors. The one serving the master suite has a separate shower compartment. Both have opening windows for ventilation.

The master suite features a pedestal double berth, accessible from three sides, with a large drawer at its foot. There's a vanity cabinet with a mirror, along with storage lockers at eye level along each side of the cabin. A floor-to-ceiling hanging locker sits in the aft starboard corner.

Command Performance

Many boats the size of the F-42/5 create more saloon space by only providing one helm station — on the flybridge. This is all well and good in ideal weather conditions; however, there are going to be days when you'll appreciate an inside helm — and being able to get in from the rain and wind or heat and humidity.

The F-42/5 can be configured with identical control setups both above and below, as on our test boat. A full complement of Raymarine electronics included a radar, an autopilot, a chart plotter and digital instrumentation — with the master unit at the inside helm and a repeater on the flybridge. Our test boat's twin 480 hp Cummins diesel engines were fitted with electronic controls.

The lower station is two steps up from the saloon floor and provides good visibility when you're seated at the double bench behind the wheel. On open water, it has an unrestricted view of better than 240 degrees. Aft sight lines are good through the large expanse of floor-to-ceiling glass between the saloon and the cockpit.

The Cummins 480C-E diesels on our test boat were the highest power option available for the F-42/5. With its 320 gallon fuel tanks half full and three people aboard, the boat easily reached a top speed of 36 knots. Acceleration was smooth and sure, especially at midrange rpm.

During our test, there was a stiff 15 knot breeze — and tidal current was running around 4 to 5 knots. The F-42/5 tracked straight and true, holding its own in turns. Slow-speed maneuvering was made easier with the optional bow thruster.

I was particularly surprised by how quiet it was at the helm while we were running at cruising speed. We were doing about 30 knots when I took a sound level reading. At first I thought the calibration was off on my meter when it read 75 decibels (A), so I double-checked the settings. Then I looked again at the speed reading. Right on both counts.

The F-42/5 has a Venturi windshield that does a very effective job of minimizing wind noise. When you're sitting at the helm, there's almost no breeze in your face.

Even when running into a stiff headwind, you can carry on a conversation with the person next to you — at a normal volume level. If you hold your hand above your head into the deflected slipstream, you immediately feel the difference. And engine noise is almost nonexistent. This is a very quiet boat.

If you appreciate cutting-edge European styling, luxurious appointments and solid craftsmanship, Sealine's latest sporty motoryacht will definitely appeal to you. And the ability to make your boat instantly "grow" another 3 feet at your command will make you feel like a magician, every time you cruise.
