Built on the water, not behind a desk
Longhorn Marine Services was founded on one idea: engines fail for a reason, and finding that reason is the job. Not simply just swapping parts until something sticks.
After more than a decade working hands-on in demanding yachting and commercial marine environments, Longhorn Marine Services was built to bring dealer-level diagnostic skill directly to the dock, without the overhead (or the wait) of a traditional shop.
We are the Caterpillar marine specialist for the Gulf Coast. From routine maintenance to the electrical and mechanical faults that stump others, we run every job the same way — find the actual cause, fix it right, and stand behind the work.
Do It Right, or Do It Twice. We Do It Right.
Today, Longhorn Marine serves commercial operators — dredging contractors, towing companies, marine construction firms — and recreational owners across the Sabine-Neches Waterway and Houston Ship Channel, fully mobile and dockside.
Community
Beyond the dock, we're proud to support the Southeast Texas maritime community — including local events like the National Maritime Gala benefiting the Port Arthur International Seafarers' Center.
