🚤 On the Move – Towing Day

Ever wondered how some vessels get to the yard? Not every job starts on land — some of our projects begin with a tow to safety. Whether it's due to engine issues, overdue maintenance, or prepping for a major refit, we’ve got the gear and know-how to help get your boat out of trouble and back to its best.

Regular maintenance and inspections help prevent unexpected breakdowns. But when things don’t go to plan, we’re ready to step in.

Another big one on the hardstand!

We’ve got the Tiwi Mantawi out of the water for scheduled maintenance and inspection. Vessels like this play a key role in keeping communities connected across the Top End, and our job is to keep them running smoothly and safely.

We’ve completed deck prep and repair, applied protective coatings, and spray-painted the hull with antifoul to ensure durability and long-term performance in tough marine conditions.
