Safe sailing on the high seas

A sailing regatta demands the utmost from people and equipment. For this reason, the Hamburg Seafaring Association attaches great importance to the best quality of all technical components, including cables, in its two ocean-going yachts. The club has now installed LAPP conductors in its Haspa yacht.

Sailing has become much safer since Christopher Columbus embarked on this adventurous journey more than 500 years ago. Nevertheless, the great crossing is still a challenge today, both for the people and for the material. Who would know better than Wibke Borrmann. The 46-year-old has already taken on and mastered the adventure of crossing the Atlantic twice as a member of a sailing crew. In addition to her job in a Hamburg advertising agency and as a mother of two children, the business economist now works as a skipper - in other words, captain - for the Hamburg Seafaring Association. The HVS has existed for over a hundred years, its goal then as now: to train young people to become ocean sailors. On its journeys on North Sea and Baltic Sea and other seas of the world it leads a round dozen young people and young adults, who must work in the narrowness of a yacht only 17 meters long up to three weeks hand in hand. "On the one hand this is physically exhausting and on the other hand the sailors have to cope with themselves and the others", Wibke Borrmann calls the challenge. "This is a school for life."

Maintenance in winter

Because the physical and psychological strain on board is already high enough, there should be no nasty surprises, at least when it comes to technology. The club members take care of this in the winter months, when the two yachts of the club, the Broader View Hamburg (56 feet) and the Haspa Hamburg (52 feet), are maintained and cared for. Both boats are relatively young, the Broader View was launched in 1999 and the Haspa in 2009. Nevertheless, the sailors replace important components every few years, including the conductors for drives and controls. It was their turn at Haspa in the winter of 2018/19. "Our yachts are high-tech boats with a lot of safety-critical electrical and electronic equipment," says Wibke Borrmann, "we can only use the best components. In recent years, Haspa has also retrofitted several systems such as a satellite tracker, additional lamps and a new lithium battery, and battery management has also been revised. "At some point everything was much tinkered with and the old cables would sometimes have been too short for a new wiring," says Marvin Schlesiger, who is the HVS inspector responsible for Haspa technology. "That's why we decided to remove some of the cables and replace them with new ones so that the cable routes could be better understood and maintenance easier.

 

At Haspa, the conductors now come from LAPP - a happy coincidence, as Dr. Martin Dorner points out. He is head of technology and innovation management at LAPP and has also been sailing in regattas at the HVS for over ten years. "When I heard that the association needed new conductors, I immediately informed my colleague in Stuttgart. This colleague was Andreas Bartsch, application consultant at LAPP. Marvin Schlesiger gave him a list with the technical requirements for the cables such as number of cores, cross-sections and quantities. "The cables should be of the highest possible quality and have a high level of reliability," says Schlesiger. On LAPP's website, the student had already selected several conductors for offshore plant technology at Kiel University of Applied Sciences, but Bartsch advised him on other types. Some conductors run through the engine compartment and might not have been able to withstand the heat there.

 

The choice fell therefore on these three ÖLFLEX control conductors:

- ÖLFLEX HEAT 125 MC: This conductor is suitable for a wide temperature range of -55°C to +125°C. It is approved by Germanischer Lloyd for use in shipping. However, this approval is not required for Haspa.

- ÖLFLEX HEAT 180 SIHF: This silicone conductor is even suitable for temperatures up to 180°C, such as can occur on hot engine parts.

- ÖLFLEX H07RN-F extended version: This rubber conductor is suitable for temperatures from -40°C to +90°C.

Corrosion-resistant and halogen-free

The following applies to all conductors: They are highly temperature-resistant, because it can get very hot below deck, but there can also be frost on deck. All conductors are halogen-free. This is important if there is to be a fire on board. Halogen-containing conductors with a PVC jacket, for example, develop corrosive vapors when extinguished with water, which would be fatal in the middle of the ocean, because escape is impossible there. And, of course, all conductors are water-resistant, regardless of whether they are in contact with fresh water or salt water. The tinning of the copper conductors over the entire length provides extra corrosion protection.

 

"I am very satisfied with the conductors, the cooperation with LAPP was great," praises Marvin Schlesiger. When Haspa Hamburg is back on the road in spring, the order for LAPP will be completed for the time being. "But of course we will stay in contact with LAPP", says Schlesiger, "because the Yacht Broader View Hamburg certainly needs new conductors at some point and I have already told my colleague about my positive experiences with LAPP".
