SINCE 1946
No Project Too Complex
“The shipyards we work with don’t build off-the-shelf vessels. They realize technically demanding and time-critical unique pieces, where there is no room for error. That is exactly our world.
Since 1946, we have been working in this environment as a turnkey partner who takes responsibility. From initial planning to acceptance. And when things get tight, even more so.”

Managing Partner LETHE GmbH
MOVING FORWARD TOGETHER
The partnership truly begins after handover
Anyone who outfits a ship knows it well. We leverage this advantage for maintenance, repair, and modernization throughout its entire lifecycle. And not because we have to, but because our customers keep coming back.
SINCE 1946
Always One Step Ahead
What began as a craft business is today a leading turnkey partner for megayachts and naval vessels in Europe. A story of precision, courage, and the will to master the industry's most complex projects.
