Ocean Craft Marine designed the 9.5 Meter Vessel Interdiction and Boarding Team Delivery Craft (9.5 M VI-BTD) to be a rigid hull inflatable boat that can be pulled alongside another vessel to transfer a boarding team underway at speed. She measures 31’2” (9.5 m) with an inflated beam of 10’5” (3.17 m) and a deflated beam of 8’3” (2.51 m), which means it can be loaded into a C 130 cargo plane or trailered on-road without wide load permit. When powered by a pair of 300-hp Evinrude E-TEC G2 outboards, she tops 55 mph and can run through just about anything thanks to her V-bottom design and shock-absorbing seats and helm console.
Twin Evinrude E-TEC G2 300s Were Specified
Ocean Craft Marine (OCM) builds boats for military and commercial applications which are in the “no-failure” zones of operation. That means that everything going into these specialized boats must meet high standards of strength and reliability. It was for that reason that the builder specified twin Evinrude E-TEC G2 300s for the 9.5 M VI-BTD. Because these engines have over 100 fewer parts than conventional 4-stroke outboards, internal steering and gear shift that are impervious to the elements, a magneto electrical system so that it is not vulnerable to slipping belts, and an internal lube reservoir, among other features, the builder deemed these engines to be the best for this particular 9.5 M application.
Shock Absorbing Console.
The entire helm console is engineered with a system that absorbs shocks on three axes, fore to aft, side-to-side and corner-to-corner. As conditions worsen, the shock absorbers stiffen to better dampen the ride.
Each crewmember wears a wireless headset with a voice-activated microphone. The radio can interface with the VHF and a total of four different communication networks including a cell phone.
Rear-Facing Infrared Camera.
It can see what’s behind the boat at all times.
Concaved Chine Design.
The Concave Reverse Chine Designed hull bottom is designed to be able to execute turns at full throttle without incident.
Our test boat’s cockpit is equipped with four Shockwave shock-mitigating seats that feature shock absorbers made by Fox Racing, a manufacturer best known for its work in motocross and off-road racing. The boarding team members straddle the seat as he would if riding a horse and has a grab handle to hold onto. The seats fold down if more aft-deck space is needed and there’s a conventional bench-seat running across the stern that could seat three or four people. Running along the tubes on each side are large hooks to which passengers can secure tactical gear brought onboard. The inflatable tube-set has large nonskid pads that facilitate stepping aboard and the entire deck of the boat is finished in a nonskid rubber mat.
While the individual seats in the cockpit have their own shock absorbers, the entire helm console is on its own shock-mitigating system also developed by Fox Racing. The whole structure sits a full 12” off the deck and has four large pneumatic shocks on each corner plus a series of smaller pneumatic pistons underneath, all of which dampen the ride in rough conditions.
The Helm Seats.
The boat coxswain and a navigation-officer transit in high-backed shock-mitigating bucket seats also made by Corbin Seats. They’re angled slightly aft with the thigh supports raised to position the occupant in as secure a riding position possible. Each has padded armrests and folding grab handles equipped with motorcycle handlebar grips that let the rider hang on during a rough ride. Ocean Craft Marine equips the boat with seatbelts, but our test captain, a former powerboat racer, opted not to wear his.
We would expect the dash of a boat designed for such serious use to be equipped with a plethora of equipment – and it is! For navigation, the carbon-fiber panel includes two Garmin 7610 multi-function touch screen display that serve multiple functions including chart plotter, side scan sonar, high-definition radar, engine telemetry and more. There are also two cameras on board, a FLIR M-324XP articulating thermal camera that is operated with its own control, and a Garmin GC-10 color-video and low-light infrared capable camera that faces aft and acts as a rear view mirror. It’s displayed on the Garmin multi-function screen. The steering column telescopes and tilts so the driver can customize his operating position. The digital shift/throttle controls is mounted on an ergonomic bump-out. The boat is equipped with 100 watt loud hailer, Whelen Siren System and police LED light bar on the hinged, folding mast.
The vessel’s communication system is provided by David Clark Company, which makes systems for the aviation, marine and other industries. Each passenger wears a wireless headset with voice-activated microphones and if a tactical unit is boarding a hostile vessel members can stay in touch with the driver of the 9.5 M VI-BTD throughout the operation. Additionally, the VHF radio, cellular phones and other devices can all be interfaced into this network.
In the front of the console are two large hatches that open to reveal all of the NMEA connections, the charger for the AGM batteries and the base station for the communications system. Replacement batteries for the headsets charge in a base station so communications will never be lost.
Storage and Deck Hardware.
A hatch in the step up to the bow opens to reveal a good-sized locker. The anchor locker is in the foredeck and it has plenty of space for ground tackle and a rode. Just forward of the anchor locker is a heavy-duty bollard. There’s a similar taller bollard aft ahead of the outboards.
Evinrude E-TEC G2 300 Engine
The Evinrude E-TEC G2 300 is probably the most technically advanced outboard engine on the market in class. In a nutshell, this 3.4 L engine provides 4-stroke fuel economy at cruising speeds with 2-stroke torque at the low and mid RPM ranges. Its strongest suit, however, is its low-maintenance design which integrates this steering and gear shifting into the body of the engine with no external rods or cylinders. Scheduled maintenance isn’t required for 5 years or 500 hours.The E-TEC G2 has an internal oil reservoir, an 81-degree tilt range, and has auto-winterization. Its beltless magneto system is more reliable than the automobile-type alternators used on most other outboards. The engine was designed from the beginning to be saltwater-ready and carries a 5-year factory backed warranty which includes corrosion.
We tested the 9.5 M VI-BTD with a pair of Evinrude E-TEC G2 300-hp outboards turning 15 ¼” x 19” Rebel three-blade stainless steel props through 1.85:1 reductions. With five people aboard and a half load of fuel, the 8,575-lb. (3,889 kg) boat hit a top speed of 55.0 mph at 5900 rpm while burning 47.75 gph, which gave us a range of 207 statute miles.
came at 3500 rpm where the boat ran 28.6 mph and burned 13.35 gph, boosting the range to 385 miles with 10% of the boat’s 200-gallon (757 L) fuel capacity in reserve.
In acceleration tests
, the boat planed in 3.3 seconds and continued to 20 mph in 4.3 seconds and to 30 mph in 5.4 seconds.
Ocean Craft Marine designs the boat with what it calls concave reverse chines and two lifting strakes per side. When we were running at top speed, Ocean Craft’s representative basically dared our test captain to crank the wheel hard over. He did so in each direction and the boat came right around cleanly. The 9.5 M VI-BTD is one of the best handling boats we’ve driven. When running in rough water, the hull’s V-shaped entry carves through the waves and the tubes dampen the impacts. With the shock mitigating seats doing their job, the physical effects on the crew are minimalized.
The 9.5 M VI-BTD’s rigid hull and deck are formed out of fiberglass. The tubes are Hypalon 1670 Dtex material with seven air compartments and intercommunicating inflation/deflation and pressure relief valves. Nonskid step pads are on top of each top to improve traction when the boarding team is transferring to another boat during an operation.
$350,000 as tested with twin Evinrude E-TEC G2 300-hp outboards and 7” ICON touchscreen, shock mitigating seats and console, navigation equipment, cameras and the communications system.
Obviously, this is a craft designed for a unique purpose, but some elements of the 9.5 M VI-BTD’s design and some of the equipment on board our test boat could be applied to a pleasure craft.The RIB design with the inflatable collar or tubes could be a good choice for yacht club tenders or other boats that are frequently used to ferry passengers between vessels. The shock mitigating seats could be a consideration for owners of boats who spend much of their time in rough water and the aft-facing camera can serve many purposes.With its high-speed handling and cushioned rough-water ride, this is a boat that we could recommend for commuting around islands in such places as the Bahamas, Virgin Islands, Indonesia, the Maine, Norway British Columbia Coastal Island, or other applications. Certainly this is not a boat for everyone, but for those who need something reliable, fast and with considerable range off shore, the 9.5 M VI-BTD could be the answer.
