Dangers in cruising sailing – and how specialist yachts defy them

Offshore sailors embarking on long passages across oceans and into remote areas face a multitude of hazards. It is no wonder that sailing circles engage in heated debates about safety concepts – especially since several well-known accidents have exposed the weaknesses of conventional production yachts. This article examines the most common causes of yacht sinkings and presents in detail two modern bluewater yachts that redefine safety: the Garcia Exploration 60 (an aluminium centreboard yacht) and the Kraken 58 (a GRP yacht with integral keel). We explain what special design features these boats employ to counter the risks. We then compare these approaches with conventional production yachts made of GRP (with bolted-on keels, unprotected rudders etc.).

Typical causes of loss: Why yachts can sink

Although modern sailing yachts today appear technically advanced and reliable, serious casualties occur time and again – up to and including the complete loss of the vessel. But what causes lie behind such total losses, and why do they pose a serious danger even for experienced crews?

• Grounding: A hard grounding on rocks or reef can tear open the hull or damage the keel and rudder attachments. A prominent example is the Volvo Ocean racer Vestas Wind, which ran aground on a reef at full speed in 2014 – the yacht was severely damaged. Even less serious groundings can lead to water ingress. Many production yachts sustain hairline cracks or bent keel bolts after ground contact. If structural damage is ignored, it can later lead to complete failure.

• Collision with floating objects (UFOs): Every sailor's nightmare is a collision with a semi-submerged object, such as a container or tree trunk. In January 2019 around 280 containers from the cargo vessel MSC Zoe went overboard in the North Sea – some drifted for days or weeks, endangering shipping. According to the World Shipping Council, an average of around 1,600 containers are lost worldwide every year. Most sink fairly quickly, but individual ones can float at the surface and cause fatal collisions. Besides containers, tree trunks, drifting wreckage or even sleeping whales pose risks. Time and again yachts ram 'something' on the open sea and suffer leaks. Dick Beaumont, owner of a 44-tonne yacht, reported a night-time collision in the South Atlantic – presumably with a whale – in which his boat decelerated abruptly from hull speed to zero. In his case the damage was minimal, but many yachts were less fortunate. A penetrating impact can breach the hull or tear off the rudder.

• Keel loss: The loss of the ballast keel is one of the most dramatic accidents, as the yacht usually capsizes and sinks within minutes. There have been several high-profile cases in recent decades. In 2014 the British yacht Cheeki Rafiki sank in the Atlantic after her bolted-on keel detached – all four crew members perished. Investigations revealed that an earlier grounding had weakened the keel structure. In 2015 the brand-new Polina Star III (an 82-foot Oyster) lost her keel off the Spanish coast and capsized; the cause was a lamination defect in the hull-keel area. Such events are fortunately rare, but the true figure is unknown, because many yachts sink without trace when they lose their keel. World Sailing compiled a list of at least 90 cases in which yachts lost their keel – and that is only the tip of the iceberg from prominent cases. The causes range from design flaws and material fatigue to undetected damage after grounding. What is clear: a bolted-on keel represents a potential single point of failure which, if it fails, leads directly to total loss.

• Rudder failure and loss of steering: The rudder is also a vulnerable point. On many modern yachts a single spade rudder protrudes exposed downwards. Even a floating object or heavy seas can break off the rudder blade or bend the rudder stock. The consequences are doubly critical: firstly, the crew loses manoeuvrability – which can be life-threatening in a storm or breaking seas. Secondly, a large leak often develops if the rudder stock is torn out of the stern. An example: in 2017 a 40-foot yacht sank off New Zealand after a floating object presumably tore off the rudder; the incoming water caused the yacht to sink despite all pumping efforts. Even less dramatic rudder defects (for instance due to material failure) can escalate if the leak at the rudder tube cannot be contained. Many production yachts have no separate bulkhead at the rudder penetration – i.e. water flows unhindered into the interior. A broken rudder can thus lead to sinking in a short time.

• Design and construction defects: Besides external influences, errors in the design or construction of a yacht can also prove fatal. In the aforementioned Polina Star III, for instance, inadequacies in the laminate lay-up were later identified. In the 2000s there were several cases of structural weaknesses on production yachts – e.g. insufficiently dimensioned structures in the keel area or faulty bonding – which led to keel failures or hull cracks. Poor maintenance or modifications can also be latently dangerous (corrosion on keel bolts, osmosis damage, delamination after grounding etc.). Such defects often remain hidden until extreme loads occur – but then components can fail abruptly.

Safety concept Kraken 58 – GRP bluewater yacht with zero keel and alpha rudder

Whilst Garcia relies on aluminium and centreboard, the Kraken 58 follows a different approach: maximum structural integrity and traditional safety features in modern guise. Kraken Yachts (founded by Dick Beaumont) builds bluewater yachts from GRP, but without the typical compromises of modern production boats. Beaumont found no yacht on the market that met all his safety requirements – so he simply designed his own models with Kevin Dibley. The Kraken 58 (17.7 m) is the mid-range model of the range and embodies two core ideas: the zero keel and the alpha rudder. Let's look in detail:

• Zero keel – one-piece keel-hull construction: Instead of a bolted-on keel, the Kraken 58 has an integral keel that is a permanent part of the hull. The hull and keel section are laminated in one piece. During construction, the complete ballast weight (approx. 6.5 tonnes of lead) is laminated into this keel. The result is a rigid, solid keel without any bolted connections – it cannot fall off. Dick Beaumont calls it 'the only truly integral keel in the world with an integrated lead ballast bulb'. Unlike traditional long keels, the Zero Keel is nonetheless an efficient fin with modern hydrodynamics: at the bottom it carries a streamlined bulb to keep the centre of gravity low and leeway to a minimum. Structurally, the Zero Keel means that keel and rig loads are distributed seamlessly throughout the entire GRP hull composite – there are no point loads at keel bolts. The risk of keel cracks after grounding is drastically reduced; the keel withstands even very hard impacts without tearing off. Kraken has carried out modelling on this – they are convinced that the hull will not suffer critical damage even if the keel strikes the ground at hull speed. In fact, Dick Beaumont's own boat (a larger Kraken) once collided at full speed with an unknown object (believed to be a whale) – and 'no significant damage occurred', apart from a slightly bent rudder shoe plate. This incident underlines the enormous robustness of the integral construction. In short: a Zero Keel eliminates keel failures as a cause of sinking almost entirely. Of course, this does not protect against all damage – even an integral keel can be deformed or, in the worst case, split open. But the assurance of not suddenly losing the keel and stability provides enormous reserves. The construction also contributes to this: the Kraken 58 has an above-average solid laminate layup in the underwater hull. Up to 40 cm above the waterline, the hull is built as solid GRP (solid laminate, no foam core), with approximately 21 mm laminate thickness. In the bow, keel and underwater areas, aramid fibres (Kevlar) are additionally worked in in many layers to increase impact resistance. A GRP hull that is inherently so thick-walled and reinforced can absorb extreme forces – even if the Zero Keel kisses rocks, the damage remains locally contained.

• Alpha Rudder – skeg-protected rudder with 'indestructibility' genes: The second pillar of the Kraken safety concept is the classic skeg rudder – albeit with a modern interpretation. Instead of two rudders (as with Garcia), Kraken opts for a single central rudder that runs entirely behind a continuous skeg . This skeg is nothing other than a fin profile permanently laminated to the hull directly in front of the rudder stock, extending to the same depth as the rudder blade. It is made of GRP but is internally reinforced with a 12 mm thick stainless steel core along its entire length. This makes the skeg extremely rigid and robust – and it is an integral part of the hull (attached during lamination, not a later bolted-on component). What's the point? The skeg acts as impact protection for the rudder: when encountering floating objects or grounding, the skeg takes the first hit, not the rudder blade. Moreover, a skeg slides more easily over obstacles where a free-standing rudder would snag and break off. The leading edge of the skeg on the Kraken is also angled to reduce the risk of lines or nets becoming fouled. Behind the skeg hangs the large rudder, mounted with three rudder bearing points (top, middle, bottom). The rudder stock itself is a massively dimensioned stainless steel shaft with a 92 mm diameter; inside the rudder blade is a stainless steel frame as the 'skeleton' for the composite. The entire rudder and skeg are additionally wrapped in aramid fabric to provide a kind of armour against impact damage. This construction is called the Alpha Rudder™. It aims to virtually eliminate rudder failure and loss of steering. Even if the boat rams an object at full force, the skeg would take the hit first – and it can withstand enormous punishment. Should the rudder stock become bent, it remains in position thanks to the triple bearing arrangement; the uppermost bearing sits on a watertight bulkhead in the stern and can even be removed at sea. For the highly unlikely event of complete steering failure, Kraken has a contingency: an emergency tiller can be fitted and deployed from deck in under 5 minutes, without needing to access the lazarette. All these measures give the crew the ability to control the vessel even after severe rudder damage – something that would force most other yachts to give up. Dick Beaumont emphasises the significance: 'Loss of steering is a very real risk for yacht and crew. Our Alpha Rudder system ensures that you can continue to steer even in circumstances that would cripple other yachts.' With its skeg rudder, the Kraken 58 is thus extremely well protected against collisions and breakage.

• Crash zones and bulkheads: Like the Garcia, the Kraken 58 also has dedicated collision zones. The forward area from the bow to the first main bulkhead is massively reinforced and designed as a crash box . From the forward anchor chain locker to approximately 45 cm below the waterline, solid material with extra laminate thicknesses has been used to absorb energy in the event of a collision. In addition, the Kraken has two watertight bulkheads in the bow: one directly behind the anchor locker and another to separate the accommodation. Aft, the Kraken 58 also has a watertight bulkhead in front of the rudder shaft/tunnel, so that rudder damage cannot cause uncontrolled flooding of the interior. This division into sectors is reminiscent of the classic bulkhead safety systems of professional expedition vessels. In addition, all through-hull fittings (seacocks) are positioned as high as possible, some above the waterline, to minimise leak risks. The saloon windows are made of high-strength laminated safety glass with special safety film.

• Laminates, structure and redundancies: The construction of the Kraken 58 is characterised by conservative solidity. The hull is laminated using hand lay-up and vacuum techniques; bulkheads and fixtures are bonded directly to the hull (no glued-in prefabricated grid). All structurally important areas (keel, mast support, rudder mounting) are integrated into the base laminate, not bolted on afterwards. This provides a high degree of stiffness and reduces the risk of connections that could come loose. Kraken also uses oversized fittings: for example, special 'fail-proof' chainplates made of solid stainless steel, which are openly visible and in the event of damage are not simply supposed to tear off, in order to prevent a dismasting (which could also endanger the vessel). The safety requirement is also evident in the engine and systems area through redundancies: for instance, a third emergency electric bilge pump with a capacity of 5,000 l/h is part of the standard equipment. The fuel system has three filters in a changeover system to keep the engine running in the event of diesel contamination. Two independent autopilot drives, dual navigation instruments, solent twin-headsail rig – all of these are standard on Kraken, to always have alternatives on long passages. Whilst these features are not primarily aimed at 'preventing sinking', they do increase overall safety and self-sufficiency.

In conclusion, it can be said that the Kraken 58 follows a very traditional approach – namely preserving the virtues of a classic blue-water yacht (integral keel, skeg-hung rudder, strong laminate, numerous bulkheads) – and combines these with modern performance and equipment. Dick Beaumont criticises that many other manufacturers would abandon such proven safeguards for reasons of cost or fashionable trends. For example, wide hulls with twin rudders and bolted-on shallow keels may be cheap and spacious, but for genuine ocean voyaging a 'dangerous path', which Kraken would never take. With the Kraken 58, his yard offers an uncompromisingly safety-focused alternative.

Comparison with classic production yachts in GRP (bolted-on keel, spade rudder & co.)

Most series-production cruising yachts – whether from Beneteau, Bavaria, Jeanneau, Hanse etc. – differ significantly from the specialist yachts described above in terms of construction. Of course, production boats are not inherently unsafe; they have proven millions of times that they can handle typical cruising conditions. However, in direct comparison, weaknesses emerge in extreme cases:

Hull construction: Production yachts typically consist of GRP in lightweight construction – often with sandwich laminate in the hull above the waterline to save weight. The underwater hull is usually solid GRP, but of lesser thickness (frequently <15 mm on 40–50-footers). Reinforcement is achieved through bonded frames/bulkheads (grid structure). Crash zones or Kevlar reinforcements in the bow are rarely found (some high-quality cruising yachts from Scandinavia have local reinforcements, but across the board this is not standard). → Consequence: In a collision, a production hull absorbs less energy; there is a higher risk of leaks. Groundings can, for example, lead to cracks in the laminate that are not immediately visible – a creeping structural problem develops.

Keel attachment: Almost all modern production yachts have a bolt-on keel. That is, the GRP hull has a flat keel stub to which a separate keel (usually cast iron or lead) is bolted using steel bolts. This method is economical in production terms (hull and keel can be manufactured separately), but carries the risk that under extreme loads the connection may fail. Keel bolts can corrode or work loose, and in a severe grounding immense shear forces act precisely on these points. Indeed, numerous cases are documented where, after ground contact, the keel bolts or laminate attachment failed – sometimes only weeks later in apparently calmer conditions, as hairline cracks enlarged. Unlike an integral keel, a bolted-on keel can therefore theoretically 'fall off' if the structure is compromised. Production yards attempt to counter this with generous safety margins (oversized bolts, structural backing plates, stringers around the keel sump). Yet ultimately a residual risk remains that with Garcia or Kraken simply does not exist due to their construction method. A further point: many production boats use shallow fin keels with minimal area (for better upwind performance) – they are not designed to bear the weight of the entire boat in a grounding. In the event of drying out or running aground, such fins can severely damage the hull at a single point, whereas long-keelers or centreboarders shrug this off without difficulty.

Rudder system: Production yachts usually have rudders without additional protection from a skeg. This arrangement does promote easier steering and saves weight, but is more vulnerable to flotsam or grounding. A floating line in the propeller is annoying, but a drifting log in the rudder can be fatal. Unlike with Krakens (skeg), on standard yachts the rudder blade will take the first blow and often break off completely. This then frequently tears open the rudder bearings/mountings, allowing water to enter. Furthermore, almost all production yachts lack an aft bulkhead; the rudder tube opens into the exposed engine room or aft cabin. This means: if water enters through a damaged rudder seal, it spreads unhindered throughout the stern of the boat.

Bulkheads and redundancies: To save costs and weight, production yachts normally have few or no watertight bulkheads. The interior is largely open-plan. A continuous subdivision as found on Garcia/Kraken (crash box, engine bulkhead, aft bulkhead) would be impractical for accommodation design on a mass-produced yacht and expensive to implement. At most there is sometimes a small collision bulkhead in the bow – but often the anchor locker is only separated from the forepeak area by a plywood board (not laminated, not pressure-tight). The result is that in an emergency, water can run unhindered from bow to stern. The crew is usually left with only the hope of fighting it with bilge pumps. Speaking of which: production yachts typically have only two bilge pumps (one electric, one manual), whereas bluewater yachts like the Kraken 58 often have three or more (with very high pumping capacity). This too can ultimately determine sinking or survival in an extreme situation.

In summary, classic production yachts are excellent all-round cruising boats for normal conditions – but in extraordinary damage scenarios they lack certain safety nets that purpose-built expedition yachts bring with them.

Voices from the field and conclusion

Safety at sea is a multifaceted subject. No boat – regardless of construction – can eliminate all risks. But construction can significantly influence the likelihood of total loss. It is therefore worth examining the philosophies behind them:

The founder of Kraken Yachts, Dick Beaumont, describes the motivation behind his yachts thus: "I saw a trend away from proven bluewater features such as integral keel, skeg-hung rudder and solid hull, towards cheaper or faster solutions. For a round-the-world boat, I believe that is the wrong path." His concept aims to "build a yacht that keeps her crew safe, whatever it takes". The owners of existing Kraken yachts seem to prove him right – many particularly value the reassuring feeling of being aboard an "indestructible" vessel.

At Garcia Exploration too, renowned long-distance sailors are enthusiastic. Jimmy Cornell, who chose a Garcia boat for several expeditions, called it the "boat of my dreams" because it is "equally suited to high latitudes and the tropics and close to the perfect cruising yacht". Indeed, voyage reports from Garcia owners – for example in the high north – show that the aluminium hull and centreboard prove themselves: groundings in ice or on sand pass without serious damage; the boats also withstand minor collisions where GRP boats would long since be leaking. The owner of a Garcia 45 wrote on the Morgan's Cloud forum about a rock strike in which only the rudder stock bent slightly, "because a crash box above the rudder absorbed the impact – the hull remained undamaged" .

However, one must remain realistic: The best protection is always prevention. Good weather routing, vigilance (especially at night on the open sea) and careful maintenance can minimise many of the dangers mentioned. The special construction of a yacht is insurance for exceptional circumstances. When these occur, however, boats such as the Garcia Exploration 60 or Kraken 58 can make the difference: they give the crew more time and options to save the boat or at least get themselves to safety. A sinking yacht is the ultimate emergency – if robust structures and clever design prevent this or delay it, much is gained.

Conclusion: In cruising there are indeed serious dangers lurking – from reef damage to keel failure. Modern production yachts sail comfortably and quickly, but in extreme situations they sometimes reach their limits. Purpose-built bluewater yachts such as the Garcia Exploration 60 (aluminium, centreboard) and the Kraken 58 (GRP, integral keel) demonstrate that safety need not be left to chance. Through crash boxes, "indestructible" keel solutions, protected rudders and well-thought-out redundancy they significantly increase the probability of survival in the event of serious damage. Of course such yachts are not mass-market – they are aimed at a small group of sailors with the highest demands and corresponding budget. But their concept can be an inspiration for the whole industry. After all, an old sailing wisdom runs: "Ships are safest in harbor – but that's not what ships are built for." In this spirit: one can never completely banish risks, but one can build a boat that courageously confronts those risks. The Garcia Exploration 60 and the Kraken 58 are impressive examples of this.
