Testimonials

Marquette Transportation Company, LLC

“Our newest 10,000 HP towboat will operate in the harshest of river conditions which requires tough, dependable gearboxes that stand the test of time. This marks our second set of REINTJES WAF 6755s, with our first set having logged more than 10 years of reliable running hours. The product and support continue to exceed our expectations and give us full confidence we will have the same results onboard the recently christened John Paul Eckstein. Thanks again to Karl Senner for another outstanding project.”

Curtin Maritime

“When Curtin Maritime, Corp. decided to repower the tug Gretchen C, working with Karl Senner, LLC to furnish a pair of WAF-675L reduction gears, was an outstanding experience from start to finish. Their team demonstrated exceptional technical expertise and took the time to fully understand our operational requirements. The quality of the gears exceeded expectations—reliable, durable, and clearly built for long-term performance.

From initial consultation to delivery and installation guidance, Karl Senner’s responsiveness and attention to detail were top-notch. That fact that the gears were already in stock in Kenner, LA, made this choice even easier.

I wouldn’t hesitate to recommend Karl Senner, LLC to anyone in the marine or industrial sector looking for trusted, high-quality power transmission solutions.”

“With the capacity to carry over 100 cars and 1,000 passengers, construction of the ferry LONG ISLAND was a big deal for our family and company.  A project of this scale requires exceptional partners.

The vessel has not missed a day since it was delivered and has greatly increased safety, comfort, and reliability for our customers.  We are grateful for Karl Senner’s commitment to excellence and proud to continue our long-standing partnership with them.”
