Towed survey  Vehicles

We have delivered several towed vehicles to date. Each project was a collaborative effort with the operator to provide a platform made to carry their specific payload.

Passive sleds are best suited for deeper applications, and when depth of operation is controlled by how much cable is paid in and out.

Active sleds are fitted with dive wings and/or elevons that the operator can control from the ship. They are used when the applications call for frequent undulations or altitude keeping, etc.

Our design philosophy

  • Adjustable ballast and buoyancy​

  • Adjustable tow-point​

  • Adjustable control surfaces to minimize pitch and roll

  • Protective elements that can be quickly replaced in case of failure in the field​

  • Large U-bolts and/or anchoring points for tag-lines​

  • Smooth under-carriage to slide the sled onto the deck and ease recovery

Tow Fish and Smaller Sleds


Our smaller platforms have a great track record.
