World Record Atlantic Crossing Succeeds in RIB

The first ever unassisted crossing of the North Atlantic just south of the arctic circle in a small, open, Rigid Inflatable Boat (RIB) has been completed by a team of dedicated adventurers led by Bear Grylls. Traveling from Nova Scotia to John O'Groats via a route which passed just south of the Arctic Circle, the expedition, which has raised around $80,000 for the UK young persons' charity, The Prince's Trust, has been completed a week ahead of schedule despite encountering icebergs and horrendous weather conditions.

The expedition, which involved a five-man team sailing the open boat across 3,000 miles of the North Atlantic on a route that saw landfall in Halifax, Nova Scotia, Mary's Harbor in Labrador, Nanortalik, Greenland, Reykjavik, Iceland, the Faroe Islands and finally Scotland, took a total of 19 days to complete. As leader Bear Grylls explains, it was a long 19 days: "There were undoubtedly more moments of jeopardy out there in those remote icy cold seas than I had ever anticipated, and in truth, if I had any idea of how frightened all of us would be at stages, I would have thought twice before I left everything - family and safety - for those northern waters. The boat was fantastic and the Caterpillar engine didn't miss a single beat, despite the ever-changing sea conditions with waves at times 30 ft high. "The support we have had from Finning (UK) Ltd and Caterpillar has been tremendous. They have not only supplied us with a first class engine but endless and unwavering technical and moral support as well as the friendship that has been the watchword of this entire expedition." The boat achieved a top speed of 35 knots at reduced fuel and water levels and in calm sea conditions. However, on the longest leg of the voyage — from Greenland to Reykjavik — spanning a distance of over 850 nautical miles, when loaded with additional fuel and water tanks, the average speed was 12 knots in sea conditions that included running into a force 8 gale.

"We believed that the crossing was tight but possible and we have now proved it," comments Bear Grylls. "There are no cabins or bunks as such - these vessels are usually used as fast, extremely manoeuvrable people movers and the boat would usually take around 12 passengers. On the challenge boat, the passenger space was taken up with stores of fuel, water, food, navigation and medical equipment. The only covered area on board was for this equipment and the team slept on top of the engine in what can only be described as a large open sardine tin!"

Silver Ships/AMBAR Marine

Having built over 200 aluminum RHIB's, Silver Ships, Inc./AMBAR Marine, has grabbed a foothold in the design and construction of aluminum RHIB's - all of which are constructed in accordance with SOLAS regulations.

The U.S. Coast Guard operates 90 AMBAR Marine Non-Standard RHIB's and the U.S. Navy Sea Systems Command operates 40 AMBAR Marine Special Service RHIB's. Silver Ships, Inc. / AMBAR Marine constructs approximately 43 vessels per year, 80 percent of which are RHIB's while the remaining 20 percent have been Patrol/Security boats, and various work boats ranging from 23 to 48 ft. (7 to 14.6 m).


Ribcraft USA introduced a technologically driven 25-ft. RIB, which integrates multiple technologies, all designed to increase driver and passenger comfort and safety, into one boat. The charge for this RIB was to take a hull with the Ribcraft 7.8 design, and start from the waterline up using completely innovative technologies to improve the overall comfort. This was accomplished by modifying the configuration to allow for longer, more comfortable offshore passages. The 7.8's proven offshore hull design features a generous deep "V", an impressive forward dead rise, and multiple full length spray rails. To compliment their in-house design team, Ribcraft tapped Dr. Johan Ullman, a world-renowned expert on back and neck injuries from high-speed performance boats, and Mark Fitzgerald of C.W. Paine Yacht Designs. Working closely with Ribcraft’s team and the client, Ullman created an ergonomically correct console, better referred to as a "cockpit."


Protector, a multipurpose, high-performance boat engineered for work and designed for response has already been customized in the U.S. for marine police patrol, search and rescue, firefighting, and other commercial operations. "Everyone who has had the opportunity to operate our new 28-ft. Port Security demonstrator appreciates Protector's deep understanding of commercial quality," says Bill Clark, Protector's director of Commercial Products. The Protector, a rigid hull inflatable boat (RIB) with a cabin, offers the safety, stability and power - even in the most challenging conditions. Introduced to the U.S. in the late 1990s, Protector already has a successful performance record with New Zealand's leaders in the industry, including the coast guard, police, search and rescue and fire departments.

Rosborough Boats

Rosborough Boats of Halifax Nova Scotia recently introduced its line of semi custom Heavy Duty Rigid Hull Inflatable boats. The Rough Water line was developed to meet the new and growing demand for Rigid Hull Inflatables with more personnel carrying capacity, workability space and operational stability. Canada's Fisheries & Oceans Conservation and Protection Police took delivery of four 30-ft. (9.1-m) Rough Water full wheelhouse, wide body boats this winter (for operations off the Canadian Atlantic coast), and more are expected to be contracted for later this season. The Rough Water designs offer a 26-ft. (7.9-m) and 30-ft. (9.1-m) narrow deep V (33 degree) configuration, as strictly Chase Boat, and the larger 30 ft. version modified deep V (24 degree) hull.

The Wide Body Rough Water 30 boasts a full 6-ft. working floor width, five crew wheelhouse and a forward cuddy area for equipment, toilet, safety gear etc. Working and cockpit floor areas are large with a fore deck area at the bow. All decks are molded in nonskid and hatches are tread plate. The under floor area forward accessed through two water tight hatches offer large storage and hold capacity, and the dual fuel tanks are equal in capacity and together provide a total of 164 gallons for extended operations.

Powered with twin Yamaha 150 hp HPDI outboards, the 30 ft. reached a top speed of 45 knots with continuous cruise speeds up to 35 knots. Rosborough's test version of the Rough Water 30 wide body was configured with a pair of Mercury 225 hp. EFI Offshore outboards that provide a top of 55 knots with a continuous cruise of 45 knots.

Honda Wins Defender Class Order

The U.S. Coast Guard will soon have a new class of up to 700 Defender Class craft patrolling the waterways. The boats, to be built by Safe Boats International will be powered exclusively by twin Honda BF225 4-stroke outboards.

The Hondas will propel the new 25-ft. Response Boat - Small, or RB-S as the Coast Guard refers to it, with maximum efficiency through 30-mph winds and six ft. seas. This is possible because of Honda's proprietary VTEC engine design and multi-port fuel injection system.

With a top speed of over 45 kts and superb handling, the Safe Boat reaches plane in less than four seconds. Its marine-grade 5086 aluminum hull with integral, sealed air chamber and polyethylene, non-deflatable foam collar make the craft one of the safest boats on the water. This design also provides it with optimum stability and unmatched durability.

The RB-S features an all-welded, self-bailing deck; insulated and heated full cabin; upper spotter windows; port and starboard sliding doors; marine electrical cable; stepped transom; and locking long gun storage. The boat's fuel tanks are .25-in. 5086 rolled bottom, fabricated aluminum. Honda Marine offers a line of four-stroke outboards from two hp to 225 hp.

Northwind Marine

Sharp is the best way to describe Northwind Marine's recent 23-ft. (7-m) and 30-ft. (9.1-m) additions to its Extreme Task Force Line of Aluminum-hull Rigid Inflatable Boats. With a 25.5-degree transom dead rise and a 36-degree waterline entry point, the first of the new models to finish production at the Seattle Wash. facility is the 23-ft Extreme. According to Bruce Reagan, president of Northwind Marine Inc., the company has received many requests for a boat of this size with a very sharp deep-V hull. The latest 23-ft Extreme to be put in service is with the Alaskan State Troopers. Outfitted with a T-top, three-sided center console and twin 130-hp Honda four stroke engines, the state trooper boat reaches top speeds of 40 knots. "The 23's are being configured with single or twin outboard engine packages and several different deck arrangements," Reagan said. Northwind Marine's other new boat addition, the 30-ft. Pilot Master, has a 24-degree transom dead rise and a 42-degree waterline entry point. The commercial models undergoing production are powered by twin 240-hp Yanmar diesels and Hamilton 274 waterjets. The recreational version is typically produced with 225-hp outboards. The development of the full cabin Pilot Master resulted from the popularity of a similar 27-ft. (8.2-m) version known as The Enforcer. The intent of the 30-ft version is to provide a very seaworthy craft with a large workable deck space while maintaining the ability to trailer the boat without permits. The Pilot Master has a 10-ft, 10-inch beam, but with the Wing collar deflated it can be legally trailered.
