Step into the cockpit of the average 25-foot midcabin performance boat and you find a straight bench seat with sole space ahead of the bench so passengers can stand up behind the driver's and co-pilot's seats if necessary. But when you think about it, how often is standing necessary? How often do you attack rough water in a 25-footer?

In creating the cockpit layout for the Genesis 25, the builder made a trade-off. They elected to lose standing space behind the co-pilot's bucket seat in favor of creating an L-shape bench. Not only did that offer an extra passenger seat, but it provided a rear-facing perspective. That could come in handy if you were pulling a wakeboarder, which, frankly, in a 25-foot midcabin model is a lot more likely than launching off waves in big seas.

That's just one of many amenities afforded to passengers in the 25, an offering that's as much about comfort as it is about performance.


You can buy the Genesis 25 with a less-potent engine than the MerCruiser 496 Mag HO in our test model, but we're not sure you'd want to. Sure, it would drop the price, but it also would cut into the fun. The 425-hp engine provided just the right amount of zip for the boat, which was equipped with a 1.5:1 Bravo drive and a Bravo One 15 1/4" x 24" four-blade stainless-steel propeller.

Top speed for the dual-step V-bottom was 70.7 mph on radar. At the top end, the boat did display a light porpoise that only negative drive trim, which scrubbed speed, could eliminate. Trim tabs might settle the boat completely, but they also might be a waste of money. Keep in mind that the porpoising tendency was present only at the top end when the drive was aggressively trimmed up.

From a standing start, the Genesis 25 reached 63 mph in 15 seconds, reinforcing our notion that the boat was appropriately powered. It also came on plane in 4.6 seconds without excessive bow-rise, always a plus.

Solid in the midrange acceleration department, the 25 ran from 20 to 40 mph in 4.4 seconds and from 30 to 50 mph in 4.8 seconds. It took longer, 7.9 seconds, for the boat to accelerate from 30 to 60 mph, but that was still respectable.

Handling grades were strong. Though the boat demonstrated very little slip and zero catch in radical slalom turns, it did its best work in cruising- and full-speed circles, where it stayed hooked up and carved deeply.


Genesis used various knitted and woven fiberglass fabrics, as well as vinylester resin, in the construction of the 25. Tooling and graphics were typical of a West Coast custom builder, meaning clean and crisp throughout. The base gray gelcoat was particularly striking, a welcome departure from typical rainbow hues found in the breed. Also worth noting was the clean installation of the white plastic rubrail with matching white screws.

Hardware consisted of primarily West Coast custom staples, including mushroom-style cleats and powder-painted cat-eye navigation lights. The boat also had several elliptical stainless-steel handrails mounted in color-matched bezels, as well as contoured grab handles and a ski-tow.

An electric screw jack lifted the engine hatch, which was additionally secured with a pair of hinges. Through-bolted L-angles held the engine to the stringers. The bilge was finished with spattered gelcoat and on each side of the bilge, there was a stowage bin.

Rigging was, for the most part, solid. However, a 5-foot run of shift and throttle cables could have used more support. A few stainless-steel cushion clamps, which the builder used well in other areas of the engine compartment, were all it would take.


Thanks to its L-shape configuration, the bench in the carpeted cockpit provided enough space for four or five passengers. The design also enabled the manufacturer to create an additional stowage locker under the bench. In a family oriented midcabin model, it's not possible to have too much stowage.

Rich padding was provided on the gunwales, which also were outfitted with cupholders in recessed enclosures. Ahead of the co-pilot in the port dash, there was a large locking glove box and a cupholder. The glove box was within arm's length of the co-pilot's bucket seat, which was deep and comfortable. If given a choice, we'd opt for a grab handle on either the gunwale or the dash.

The builder provided the driver with the same type of plush bucket seat. Also at the helm were the requisite gauges, from Faria, as well as a Livorsi Marine throttle and shifter, and several accessory switches.

In keeping the deck fairly tall, the builder created a carpeted midcabin that won't frighten full-size, claustrophobic adults. Our lead inspector is 6 feet tall, and he sat on the facing lounges in the cabin without coming close to bumping his noggin on the fabric-covered ceiling. There were stowage compartments behind the lounges, as well as map pockets on the gunwales that could handle smaller items.

Natural light and ventilation in the midcabin were good, as you'd expect with cockpit and bow entryways. But the builder also included interior light fixtures to make the cabin usable after dark.

Though the open bow lounges weren't especially long, as most of the interior space was dedicated to the cockpit and midcabin, they were deep enough in the boat. There were two lockers under the bottom cushions for lounges, and the Genesis logo was stitched into the backrests.


There's no question that the Genesis 25 had sport boat looks and performance, as well as upscale construction. The boat ran 70 mph, accelerated strongly and carved sweet turns. But beyond that, it's really a family boat, with its L-shape cockpit lounge, adult-size midcabin and functional open bow. The people at Genesis know that when it comes to fun on the water with your family, comfort counts most.
