Chaparral 21 H2O Sport OB running
The Chaparral 21 H2O OB Sport has an LOA of 21’6” (6.55 m), an 8’4” (2.54 m) beam, and 12 passenger capacity.


One of Chaparral’s clear missions here with the 21 H2O OB Sport was to take the popular features and design of the 21’6” (6.55 m) 21 H2O and give it the advantages brought by an outboard motor. This opens up the 21 H2O OB Sport for freshwater and saltwater excursions, making what is already a family-focused bowrider even more versatile.

There is a growing trend to outboard power in sportboats and the 21 H2O OB Sport capitalizes on that. The outboard engine is lighter which gives the boat potentially better performance. It certainly opens up storage space because the engine box is eliminated, and because there are fewer fuel line connections inside the boat, it is inherently safer.

Chaparral 21 H2O Sport OB transom
The transom sun pad is one of the 21 H2O OB Sport’s central design features, extending port to starboard with the ability to prop up either side as a backrest.

Major Features

    Transom Sun Pad. Spanning the full width of the transom, the aft sun pad can lift and prop up backrests, lift up entirely to access storage and walk-through, or flatten out completely, providing an excellent lounging space when the boat is not underway.

    H2O Wiring. Equipped with easy-access circuit breakers, the loom wrapped wiring features water tight triple O-ring sealed connectors help ensure electrical integrity.

    Hydro Lift Extended Running Surface. The 287 SSX’s hull design utilizes an extended running surface, which allows the “v-plane” to continue aft of the transom. This improves performance in a number of ways.

    Port/ Starboard Console Storage. The port and starboard consoles at the helm provides space for storage with hatches on the inner side of each, in the walkthrough to the bow.

    Standard Trailer. A tandem-axle, black powder-coated trailer with brakes and 14” wheels is included in the package price.

Features Inspection


Chaparral 21 H2O Sport OB bow
The bow seating section. Note the bolster backrests, cup holders, and carefully placed grab rails, as required by ABYC standards.

In the bow we find a dedicated anchor locker, something that all boats should have but which -- sadly -- are being eliminated on many entry level sportboats. The stainless steel grab rails don’t wrap around the section entirely, and are instead short, but are thoughtfully placed to port and starboard. Stereo speakers are just below the grab rails, with cup holders just near the backrests as well.

Chaparral 21 H2O Sport OB bow storage
The bow seating section’s seat cushions lift up to reveal storage bins below which has been designed to handle a Danforth-style anchor.

The seat cushions lift up to reveal storage bins on the port and starboard sides, with the forward panel remaining a flat surface. We’d like to see as hatch here to add storage.

A design aspect we like in the bow is the relatively wide center section forward with back rest bolster. This creates a comfortable seating spot for one person. Also, the foot well is wide enough to handle feet and knees from both sides of the cockpit.


Chaparral 21 H2O Sport OB bow door
A view of the walkthrough door between the bow and cockpit. This is a welcome feature to have on chilly mornings.
Chaparral 21 H2O Sport OB console storage
The storage in the port console, with the latch door open.
Chaparral 21 H2O Sport OB console storage
The starboard console storage, with latch door open. Storage space abounds on this 21-footer.
Chaparral 21 H2O Sport OB locker
The below deck locker between the captain and companion’s seats, is a good place for skis or a wake board. Note the gas-assisted strut.
Chaparral 21 H2O Sport OB helm seat
The captain’s seat, on the starboard side of the 21 H2O OB Sport. Note the gunwale armrest.
Chaparral 21 H2O Sport OB companion seat
A view of the companion’s seat. Note the armrest in the gunwale and the curved windshield, two things we sometimes don’t see on entry-level sportboats.
Chaparral 21 H2O Sport OB glove box
A view of the glove box to port, seen here open. The glove box can lock, but we’d like to see it a little deeper.

All seats are upholstered in stain Resistant vinyl with Nano-technology. The two helm bucket seats have flip-up bolsters and forward/ aft adjustments. The seats do not have armrests, although each has an arm rest added to the gunwales. The port side companion’s seat also has a small nook in the gunwale that has a cup holder and can be a resting place for a phone or other device. Forward is a lockable glove box, and a stainless steel grab rail.

Chaparral 21 H2O Sport OB helm
A view of the helm dash. Note the simple design, with hand-stitched brow, H2O gauges with stainless steel bezels, and roadster-style steering wheel. We like the cupholder to the right because it is an ideal place for a smart phone.

Helm Details. To starboard is the helm, and the captain’s seat is identical to the companion’s, just situated a bit more forward. The helm design is new, and features a custom hand-stitched brow. The digital gauges have aluminum faces accented with stainless steel bezels. The gauges are fog-resistant and built to last, with a noted effort to provide gauges that are visible and legible in nearly every lighting condition.


Chaparral 21 H2O Sport OB cockpit seats
A view of the cockpit seating on the 21 H2O OB Sport.

Abaft the helm seats is the cockpit seating. The seating is full-beam, with the middle section resembling a loveseat and two seats flanking to port and starboard with no armrests, making it essentially all one seating section for three or four people.

Stern/ Swim Platform

Chaparral 21 H2O Sport OB sun pad
The transom sun pad, seen here with one “wing” up, creating a backrest. Note the deck space provided for moving around the outboard motor well.

The transom sun pad, is a versatile design that can flatten out for laying in the sun, prop up on either side for a backrest, and can lift completely to reveal both storage and the transom walk-through, both on the port and starboard sides.

Chaparral 21 H2O Sport OB sun pad
Another view of the versatile transom sun pad in action. The hatch lids to storage compartments serve double-duty.

The sun pad consists of a largely stationary middle panel with “wings” on either side. The wings lift and prop up via the lids on the storage hatches below, creating something more like a chaise lounge with backrest. They can then be folded into the center panel if access to the swim platform is underway.

Chaparral 21 H2O Sport OB sun pad wings
The sun pad’s wings can be lifted for access to storage space and clear the way for walkthrough to the swim platform.

The swim platform is clearly designed for safe maneuvering around the outboard motor. The platforms both port and starboard are large enough to launch swimmers and tow-sport enthusiasts. A three-step reboarding ladder is to port under a deck hatch.

Chaparral 21 H2O Sport OB tower
A view of the arch tower, which is optional on the 21 H2O OB Sport, with the ski tow line point in use.

Note that the 21 H2O OB Sport has the option to add an arch tower, which can provide a ski tow line point, board racks, and other watersports amenities.

Chaparral 21 H2O Sport OB running
The Chaparral 21 H2O OB Sport is a great ride, great value boat that, while it may not be for everyone in design, will provide a lot of fun for those who take the plunge.

The 21 H2O OB Sport is a well-crafted vessel like all in the Chaparral fleet. The design touches make for a comfortable, fun boat without putting a thumb on the scale with standard extras that few in this market need or want to pay for.

The 21 H2O OB Sport is a competitively priced bowrider; but because of her Chaparral DNA, she has a lot of little design touches that set her apart from most other entry-level sportsboats on the market. We are talking about things such as the anchor locker, rounded windshields, inset light on the transom, curve in the cockpit bench seat, and signature “engine” exhaust ports on the port and starboard stern quarters.

All of these details, and more, make this entry-level boat one that even veteran boaters can be proud of.

All fuel consumption numbers are the total for all engines in the boat. Speeds are measured with Stalker ProSports radar gun or GPS. Fuel consumption (gallons per hour) measured with Floscan digital fuel-flow meter or by on-board factory-installed diagnostic instruments. Range is based on 90% of published fuel capacity. Sound levels determined using Radio Shack digital decibel meter on A scale. 68 dBA is the level of normal conversation. Time to plane is measured from start of acceleration to formation of rooster tail behind boat.
