The DRS
DRS: a system designed for fishermen and developed with fishermen.
The result of Devocean’s expertise and talents, the DRS (Devocean Ropeless System) allows you to fish with your fixed gear in a competitive time, while cohabiting harmoniously with marine mammals.
Our innovative on-demand fishing system has been designed and tested in close collaboration with snow crab fishermen. It’s simple to use, practical, safe and allows you to fish in an area closed due to marine mammals.
How does DRS work?
Our on-demand buoy attaches to fishing gear and sinks with it. It includes a spool on which the necessary line is wound so that it can surface.
When you’re ready to reel in your catch, you send an acoustic signal to the buoy from the boat, triggering the latch and allowing the buoy to surface by unwinding the rope. All you have to do is retrieve your gear, just as you would with traditional equipment.
This eliminates the risk of entanglement for right whales and other marine mammals.
To further simplify the process, our system include an automatic rewinding unit. Once the buoy is retrieved and placed on the rewinder, the rope is automatically rewound onto the spool, making it ready for the next deployment. This saves time and reduces labor, but also ensures the rope is neatly and securely stored, maintaining the system’s efficiency and reliability.
Latest model: DRS-C
DRS-C: a compact ropeless system designed for lobster fishermen and developed with fishermen.
Building on Devocean’s expertise and on the proven DRS approach, DRS-C (Devocean Ropeless System – Coastal) is a simpler, less expensive on-demand solution engineered for shallow-water fixed-gear fisheries, first and foremost lobster.
Designed as a single spooled unit to take the least possible deck space, DRS-C unwinds and floats like a yoyo—optimizing ascension time and reducing on-surface drag in high-current conditions. It is intended to be used with the manual rewinder designed for it by Devocean’s team, for straightforward coastal operations.
DRS-C keeps the buoy attached to the gear on the seafloor and brings it back to the surface only when you activate it—without persistent vertical lines—helping you operate efficiently while cohabiting harmoniously with marine mammals, and supporting access to areas closed due to their presence.
Shallow-water ratings (DRS-C buoy):
- Max depth: more than 311 ft (95 m / 52 fathoms)
- Standard rope capacities: 130 ft (40 m / 21 fathoms) of 5/8″, 230 ft (70 m / 38 fathoms) of 1/2″, or 575 ft (175 m / 95 fathoms) of 3/8″
- Expandable capacity (bulk orders): rope length can be extended for bulk orders by supplying a longer spool (extended versions available).
Can be added to the fishing equipment already in use.
No time wasted.
Impossible to be triggered by anyone else.
Allows fishing in closed areas.
