Survival Equipment

Since lifesavers have gone to sea, they’ve relied upon survival equipment to protect them and enhance their ability to help others.  Beginning in the 1970’s, the maritime industry began to see dramatic innovations in this field. (1)

Retired Surfman BMCM Thomas McAdams and Surfmen of old, “look at the present and marvel at the equipment of today.” (2)(3)  Over the decades, professional rescuers have graduated from oil-skin rain coats and cork lifejackets to complex hypothermia protective garments, signaling devices, helmets, and safety belts. (1)

1997 Equipment

On 12 February, CG 44363’s boat crew wore anti-exposure coveralls, boat crew survival vests, and heavy weather safety belts. (4)

Lifesavers’ prime concern is protection from hypothermia and floatation in the event of immersion.  In the Pacific Northwest, water temperatures remain near 50°F and debilitate a victim in minutes. Professionals use a “50-50-50 rule” to predict survivability: a victim has a 50% chance of survival for 50 minutes in 50°F water. (5)

The anti-exposure coveralls worn by Bosley and his crew- sometimes called “Mustang suits” for their manufacturer’s namesake- combine floatation and thermal protection in one foam-filled suit.  The suit’s outer shell is a tough, nylon material that encapsulates about ½” of closed-cell foam.  While the suits are bulky, they keep wearers fairly warm and dry until they enter the water. (5)

Once immersed, anti-exposure suits fill up with water and the wearer becomes soaked.  By tightening straps and cuffs, the wearer ensures that the layer of water warmed by their body heat stays close to their core.  The U.S. Coast Guard’s Boat Crew Handbook estimates that in 50°F water, a person will remain usefully conscious for about three to five hours. (5)

Over their lifejackets and survival suits, all Coast Guard crew members wear a boat crew survival vest, also called a “pyro” (pyrotechnics) or “SAR” (search and rescue) vest.  Survival vests provide a crewmember with a variety of means to signal their position should they fall overboard: they contain a strobe light, whistle, signal mirror, knife, meteor flare kit, and day/night handheld flare. (6)

Crews have always needed to keep themselves tethered to their pitching lifeboats.  Lifesavers of old used segments of line to tie themselves to their vessels, but modern crews use boat crew safety belts, also called “surf” or “heavy weather” belts. (1)(6)

These robust belts wrap around a crewmember’s midsection and come with two side straps with carabiner-like clips to connect to D-ring attachment points around the boat. (6)

Though helmets were available and stowed on board, the CG 44363’s crew did not don them. In the 1990s, crews wore full-cut “Pro-Tec” whitewater helmets with reflective tape and a Velcro patch for attaching a strobe light.

The first dry suits were evaluated by the Coast Guard in the late 1980s. Testers at the National Motor Lifeboat School were impressed with the performance of Typhoon-brand suits from the United Kingdom, where the Royal National Lifeboat Institution was already using them. (7)(10)

In 1997, dry suits were appearing at Coast Guard stations.  When dry suits were first issued to the fleet, some units only received a handful to be shared amongst twenty or more boat crew members.  On 12 February 1997, the second boat crew on CG 44393 heard how miserable the conditions were and opted to wear their dry suits. (7)(10)

Dry suits keep the wearer completely dry and can extend a crewmember’s useful consciousness to 10 or 12 hours.  Dry suits act like a watertight rain coat for one’s entire body and have tight rubber or neoprene seals at the wrist and neck to keep water out. (5)(6)

Like a rain coat, however; dry suits do not provide much insulation or floatation.  To maintain body heat, crews wear polypropylene thermal underwear against their skin, and fleece “bunny” suits above that.  Dry suits are not inherently buoyant, so crews must also wear an appropriate personal floatation device over top, followed by the standard boat crew survival vest. (6)

In 1997, boat crewmembers carried pyrotechnics, a knife, and other audio and visual signals. Today, the Coast Guard has added personal locator beacons (PLBs) to each survival vest. (5)(6)

Operating on the same internationally recognized frequency as vessel emergency position indicating radio beacons (EPIRBs), these PLBs last for hours and direct rescue crews to within a tight radius of a survivor using search and rescue satellites. (5)(6)

Today’s helmets are simpler and lighter than those of the 1990s, even though some sailors expressed concerns about the ear openings of the Pro-Tec full cut helmets. (7)

In total, today’s boat crewmembers are each issued over $3,000 of survival equipment. (6)

The Rescue and Survival Systems Program After the Mishap

The investigations into the loss of CG 44363 directed headquarters to recover all survival equipment and evaluate it for premature failure. Additionally, ADM Kramek directed that headquarters reevaluate the boat crew helmet design. (4)(7)

While the specific survival equipment changes to come out of the CG 44363 mishap were relatively few, the tragedy marked the early beginnings of sweeping improvements in the Coast Guard’s rescue and survival system (R&SS) program. (7)

Following another deadly Coast Guard accident at Station Niagara, New York in March 2001, the Coast Guard accelerated improvements to its R&SS program. Crews continued being issued more and better personal equipment, documentation and maintenance systems were enhanced, standardization inspections improved, and policy clarifications addressed prevalent operational inconsistencies that put crews at risk. (7)(8)(9)

Today’s crews have excellent equipment and a strong R&SS program that has grown out of mishaps like these. To understand how the Coast Guard’s R&SS program continues to evolve, an examination of two specific pieces of equipment is helpful. (6)(7)(10)

Boat Crew Safety Belts

The first boat crew safety belts were helicopter door-gunner belts purchased through military supply sources. Mishap-generated changes to safety belts occurred as early as the 1980s, following an incident at Station Tillamook Bay, OR. (10)

Between 1987 and 1988, the Coast Guard’s National Motor Lifeboat School at Cape Disappointment, WA tested different safety belts, helmets, and dry suits. The top-performing belt by Lifesaving Systems Corp. was adopted service-wide in 1990 (see the circa 1993 belt below). (10)(11)

Mishaps continued to drive improvements: during a 1993 rollover at Station Grays Harbor, WA, five of six crewmembers slid out of safety belts when their 52′ motor lifeboat rolled over. (10)(14)

Afterwards, the Coast Guard modified the design with thicker, grippy material on the inside of the waist belt and a better quick release buckle. Additionally, Headquarters was directed to clarify proper adjustment and use of safety belts in the Rescue and Survival Systems Manual. (10)(14)

1997 Inquiry

In 1997, boat crew safety belts had robust waist security and were fitted with non-locking wire gate clips. This model of safety belt, also by Lifesaving Systems Corp. and very similar to today’s belts, was first issued in 1994 and replaced the version shown above, which was issued from 1990 and 1994. (4)(7)(10)(11)(12)

Some of the facts about how belts were used by the crew of CG 44363 are unclear in the administrative investigation. In fact, even ADM Robert E. Kramek noted that this investigation exhibited, “an absence of detail on the issue of boat crew safety belts and helmets.” This matter deserves further examination and sheds light on the way the Coast Guard drives change. (4)(7)(10)

condition of beltS

After the incident, the National Transportation Safety Board and 13th Coast Guard District held a news conference and displayed a belt with failed clips that was recovered from one of the victims: The clips were stretched out. One belt was never found and likely remained attached to part of the superstructure that sheared off and was never recovered. SA Wingo’s belt was intact and left aboard CG 44363. Another belt was found on James Island in perfect condition, with both clips connected to each other. (4)(7)(10)

The way this belt was found indicates that it came off of a crewmember during the rollovers. Also, the arrangement of the clips shows that they were not secured to D-rings on the boat. The way the clips were connected to each other is identical to the way that crewmembers used to stow—and still stow—the clips of their safety belts when not in use: on the top edge of their survival vest. This belt belonged to BM2 Bosley. (4)(7)(10)

Surfmen who were present for the investigation vividly remember how the force of the rollovers distorted the damaged belt that was recovered with one of the victims. On this belt, one clip had been attached to the boat and the other to the coxswain screen when parts of the coxswain flat separated from the hull during the second rollover. With each clip pulling in opposite directions, the belt and its hardware were placed under extreme stress. In addition to elongating the clips, this force was significant enough to cause the belt’s stitching to pop in places. Similar bidirectional pulling force also injured the hip of another crewman who was ripped out of the belt that was never found. (4)(7)(10)

Of the six clips in use aboard CG 44363 that night, only one of SA Wingo’s remained attached after the final rollover (his other clip detached from the coxswain screen when it was carried away). While safety belt hardware did “fail”, it is not considered a contributing factor in the three deaths; no safety belt can be expected to withstand the force of an 18-ton steel vessel rolling three times over rocks. And from a structural standpoint, the hardware’s integrity performed remarkably well—”too well” as some Surfmen contended—because of the stretching the belts were able to endure and the injuries incurred to the wearer before the clips disconnected from their attachment points. (4)(10)

While the damaged belts did not cause the deaths in this accident, the Coast Guard felt that their design was inadequate, and in December 1998, reacted by changing the clip design of future boat crew safety belts. (4)(7)(10)(15)(17)

Clip Re-Designs

A December 1998 13th District message announced that the Quillayute River mishap, “prompted a review of boat crew personal protective equipment, resulting in the identification of a boat crew safety belt superior to the one currently in service.” (10)(11)(18)

The message detailed a new design by Lifesaving Systems Corp. (the “Talon” clip) that locked once closed, because the feature would “prevent inadvertent release of the snap hook from an attachment point.” The change was effective immediately and all non-compliant models were to be removed from service within 180 days. (10)(18)

Testing and actual use of the Talon clip uncovered problems, however. The 1998 message warned commands that the design required users to “be thoroughly familiar with the operation of the hook… paying particular attention to working the latch gate release.” It cautioned that, “operation should be second nature.” (6)(7)(10)(18)

Surfmen who used this model of belt remember how difficult the mechanism was to operate with cold, wet hands, and how the opening was too small for easy use with a lifeboat’s D-rings. Considering how the clips from CG 44363 held-on to the point of popping belt stitching, many Surfmen felt the modification was a “knee-jerk reaction;” they didn’t assert that any belts had “failed” on 12 February. (6)(7)(10)(18)

In addition to difficulty of use, the Talon clips suffered structural failures. Members at the National Motor Lifeboat School documented how the Talon clip could break apart when subjected to tension and side force. Because of the difficulties, numerous Surfmen kept their original, non-locking safety belts and continued to use them, in contravention to the change. (10)

Non-Locking Clips Reauthorized

In June 2000, the Coast Guard issued a routine message directing units to remove belts with Talon clips from service, and in 2002 Lifesaving Systems Corp.’s present-day “Super Talon” clips were developed and implemented. Though they had initial quality problems due to metallurgical integrity, they have operated well since. (6)(10)(11)(15)

The 2007, 2014, and current 2015 editions of the Rescue and Survival Systems Manual all state that belts with the “Super Talon” clip are the only model to be purchased, but allow existing stock of belts with non-locking wire gate and “Talon” clips to be used until unserviceable. (6)(7)(10)(15)(18)

It is not known when exactly this change occurred, but the Coast Guard came full-circle from a requirement for locking clips, back to an acceptance of non-locking ones. Throughout each change, every edition of the Rescue and Survival Systems Manual included notes of caution taken verbatim from the 1998 13th District message. (6)(10)(15)(18)

While reviewing the CG 44363 mishap, 13th District Commander RADM J. David Spade expressed the opinion that, “the severity of the head injuries was such that helmets would not have prevented their deaths.” Coast Guard Commandant ADM Robert E. Kramek did not agree with this assessment. ADM Kramek also directed headquarters to reevaluate the boat crew helmet design. (4)(7)

The subject of helmets is multi-faceted and spans the decades leading up to and beyond the 1997 accident. (4)(7)

Headquarters Focuses on Helmet Improvements

The Coast Guard has gone to great lengths to design or select the best equipment for its crews and compared with even two decades ago, today’s boat crews have an incredible assortment of gear. This evolutionary trajectory has taken time, however. The progressive implementation and changes seen in the service’s boat crew helmets provides an example of how this evolution has proceeded. (2)(3)(4)(7)(10)

Motorcycle helmets were the first to be adopted by the Coast Guard’s motor lifeboat community in the 1960s and 1970s. Then, between 1987 and 1988, the National Motor Lifeboat School began evaluating less-cumbersome watersports helmets. (1)(7)(10)

Evaluators sought alternatives because motorcycle helmets were heavy, inhibited communications, and felt claustrophobic when crews ended up in the water. (10)(14)

Additionally, faster, rigid hull inflatable boats (RHIBs) were entering service and exacerbated another issue: neck strain. Many users had already experienced head and neck strain from the force of waves, and high-speed RHIBs promised to make this phenomenon worse. A Royal National Lifeboat Institution study on high-speed ejections corroborated these concerns. After thorough evaluation, testers at the National Motor Lifeboat School selected the Pro-Tec full-cut helmet. (10)(14)

Replacement was slow and issues persisted for several years. Of the six crewmembers involved in a 1993 rollover at Station Grays Harbor, WA, two had their motorcycle helmets ripped off by the violent motion. Investigation into the rollover noted that crewmembers were reluctant to use kayaker helmets (relatively new at that time) because they thought the motorcycle helmets were much stronger and offered extra warmth. (10)(14)

Following reports like this, commercially available whitewater sports helmets continued to replace motorcycle helmets. The Coast Guard had learned that motorcycle helmets behaved like drogues underwater, could be ripped from wearers’ heads, and created a risk to crews. (1)(7)(10)(14)

After 11 September 2001, Boat Forces advanced homeland security missions and boat crew equipment adapted too. In 2009, after years of using plastic kayaker helmets, the Coast Guard adopted a military-style “special operations headset adaptable helmet” (SOHAH) made by Gentex as its “primary boat crew helmet”. This model offered ballistic protection (blue), and eventually came in a non-ballistic version (orange, bump protection only). (6)(10)(15)(19)

With this change, the familiar kayaker helmets would no longer be authorized after October 2011. The Coast Guard’s surf and heavy weather community was generally displeased with this change. During actual rough weather use, SOHAH helmets created too much drag when hit with waves and spray. As with the first motorcycle helmets, users had their heads forced backwards from the “scoop” created by their helmet. (9)(15)(19)

In August 2011, Boat Forces changed its mind about helmets and reversed course: ballistic SOHAHs would not be the primary helmet, both SOHAHs were optional, and kayaker helmets were once again approved. (20)

Problematic All-in-One Design

One week after this announcement, Boat Forces distributed further clarification about helmets: units were reminded not to discard SOHAH helmets (since they were still authorized), and announced that it was “designing a new helmet to meet requirements of every mission for the multiple types of units.” Part of this decision stemmed from Boat Force’s concern that previous helmets were not adequately rated. In June 2012, the new helmet was available to order. (20)(21)(22)

The new “CEANT XT4” helmet was made by Italian manufacturer Mango and was tested by a variety of Boat Forces units before final approval. (10)(22)

Unfortunately, once this “all-in-one” helmet saw widespread use in the fleet, numerous helmets experienced failures under normal conditions. Users noted critical failures in the internal headband system causing the helmet to detach from its liner and fall off. In March 2013, Boat Forces issued a safety advisory about the liner problem. (10)(23)

From March 2013 to November 2016, the Coast Guard Office of Boat Forces issued four safety-related updates regarding the CEAN XT4 helmet. In March 2015, Mango began manufacturing the CEAN XT4 in the U.S. and implemented several design improvements. By November 2016, problems with the liners persisted, despite reported manufacturer mitigation earlier in the year. After four years of challenges, many units went back to buying SOHAH and kayaker helmets made by Pro-Tec and PT Helmets. (10)(23)(24)(25)(26)

The Future

Revision photo

In June 2018, the Coast Guard tried again to obtain an “all-in-one” helmet to meet the needs of the entire Boat Forces community. Building on the lessons of the previous seven years, the Coast Guard selected the Revision “Caiman,” an adapted special operations-style helmet. Rather than issue a deadline for eliminating previous helmet models from service, Boat Forces allowed units to continue using older helmets until no longer serviceable. (10)(27)

Looking to the future, lessons learned and feedback from the fleet continue to improve the efficacy of the Coast Guard’s rescue and survival systems program.
