What It Is

The Skimmer Finds It.
The Recovery Takes It Away.

Spill response and post-storm cleanup have an information layer and an execution layer. Canadian Shield split them on purpose: the Skimmer CS-520 surveys and marks; the Recovery CS-580 collects, carries and hands over — with a custody log attached to every load.

The craft is a twin-hull catamaran in the 2.4 m class, booms folded to road-trailer width for transit. Deployed, its funnel booms concentrate a 1.5 m collection front into the between-hulls channel; the craft's own motion is the collection energy, and a mesh basket-cassette in the channel is the reservoir — water passes through, solids stay. When the cassette reports full, the craft runs home, the cassette lifts out as one unit, an empty one drops in, and the loop continues. The channel is the machine, and the whole path is passive on the base craft: fewer moving parts in the dirtiest part of the job.

The cassette bay — seat, latches, lift points, load sensing, one data line — is defined once, so a new collection medium is a tooling change, not a redesign. Three fits ride the same bay: an open solid-debris mesh for municipal litter, post-storm debris and weed mats; a sealed, non-draining cassette for oily solids, where the cassette itself is the regulated-waste transfer unit; and a towed collection bag astern in the ~300 kg class that roughly doubles collection in transit-dominated work — a droppable fit that leaves the base craft unchanged.

The Premise

Fail-soft in the dirty end, accountable at the clean end.

A snagged boom or clogged mesh stops collection, not the craft. And no mode — including fault modes — can dump at sea: a fouled cassette is carried home, never jettisoned. The design's two promises are that it keeps working and that everything it takes is accounted for.

No dumping mode — in any state, including faults, by construction; a fouled cassette is carried home, never jettisoned.
Radio & GNSS aboard, openly — permitted on this surface civil line: a COTS marine autopilot with commercial RF, telemetry and GNSS.
One ledger line per load — position, load events and transfers logged throughout; the cassette is the custody container.

01 The Mechanism · Booms, Mouth, Cassette

THE CHANNEL IS THE MACHINE

Mouth → channel → cassette is the entire collection path — and it is passive. The craft sweeps at walking pace, 0.75 m/s; geometry does the concentrating; the mesh does the separating.

The funnel booms shed load before the hull does — snag-release is a requirement, not an accident. The mouth's replaceable wear lip rides 0.15 m below the waterline, and freeboard is drawn against the loaded waterline from the start: at full cassette the craft sinks about 4.5 cm and the lip is still at working depth. Two shrouded thrusters give debris-tolerant differential steering with no rudder to foul; a paddle fallback above the waterline covers the day the water is worse than the survey said. The drives are sized by mouth drag, not cruise — the honest load case.

02 The Deliverable · Chain of Custody

EVERY LOAD HAS A LEDGER LINE

What makes the CS-580 a professional tool rather than a gadget is what happens at the dock: the cassette lifts out as one sealed unit, and custody transfers to the licensed chain — logged, positioned, time-stamped.

Operators never handle loose collected material; on the oily-solids fit the sealed cassette itself is the regulated-waste transfer unit, and logging is on by construction. The swap dwell is engineered to be short — cassette out, cassette in, battery exchanged in the same pause, about five minutes at the shore station — because cycle arithmetic says the reservoir and the offload trip set throughput, not the sweep speed. Wash-down is designed in, and the design treats even wash effluent as what it legally is: regulated waste.

Recovery CS-580 · Debris & Spill-Material Collection Craft Industrial Line · Civil Work Machine · Water Trio

01Dimensions & Mass

Configuration: Twin-hull catamaran collection craft — funnel booms, between-hulls channel, swappable basket-cassette reservoir
Waterline length, each hull: 2.4 m class
Beam, booms folded: Road-trailer width — the transit constraint, carried from the first sheet
Displacement, light: 150 kg
Collected-load allowance: 60 kg / ~80 L cassette — ≈40% live-load fraction

02Performance

Effective collection front: 1.5 m, booms deployed
Sweep speed: 0.75 m/s working
Mouth lip working depth: 0.15 m below the waterline — held at working depth fully loaded (sinkage ≈4.5 cm)
Cycle, dense field: ≈25 min full cycle — ~35% collecting, transit ~500 m
Offload / swap dwell: ~5 min — cassette and battery exchanged in the same pause

03Drive & Control

Propulsion: 2× shrouded thrusters, differential steering — no rudder to foul
Fallback drive: Above-waterline paddle
Drive sizing: By mouth drag, not cruise — the working load case
Command & control: COTS marine autopilot — commercial RF, telemetry and GNSS, permitted on this line and used openly
Visibility posture: High-visibility civil scheme, radar reflector, mast lights

04Payload & Fits

Cassette bay interface: Defined once — seat, latches, lift points, load sensing, one data line
Fit — solid-debris mesh (base): Open mesh, passive dewatering — municipal litter, post-storm debris, weed mats
Fit — oily-solids sealed: Sealed, non-draining, closing lid — the cassette is the regulated-waste transfer unit
Fit — towed collection bag: Offboard mesh bag astern, ~300 kg class — roughly doubles collection in transit-dominated work; droppable, base craft unchanged
Dumping modes: None — in any state, including faults; a fouled cassette is carried home

05Materials & Construction

Hull mouldings: rPET-GF
Bridge: GF-nylon
Consumables: Neat-rPET mesh cassettes and liners — moulded on the group’s own line
Shared library: Water-trio shallow-draft hull and station-keeping library — with Skimmer CS-520 and Dredger CS-570

06Energy & Turnaround

Battery: ~2 kWh swappable pack — ~1.6 kWh usable, ~14 kg
Exchange: At the offload dwell — the battery swap rides the same pause as the cassette
Shore station: Ramp-side, shared with the Skimmer — cassette and battery exchange, wash-down

07Compliance

Patent status: Patent pending
Line classification: Civil work platform — Industrial Series charter; radio and GNSS permitted on this line, used openly
Cargo classification: Carrier of collected inert material — not a munition; no energetic content of any kind, ever
Regulatory scope: Collection, carriage and transfer of spill material are regulated activities — permits and waste-handling approvals belong to each operation
Survey scope: Skimmer CS-520 — this craft collects, carries and hands over

Freeboard is drawn against the loaded waterline: at a full cassette the craft sinks about 4.5 cm and the mouth lip stays at working depth. Dense-field cycle figures are working values — the reservoir and the offload trip set throughput, not the sweep speed. Collection, carriage and transfer of spill material — especially oiled solids — vary by jurisdiction; permits and waste-handling approvals belong to each operation and are never implied by this page.

In the Doctrine

One Incident, One Family,
One Custody Chain.

The Industrial line is the civil sibling of the defence fleet — same autonomy stack, same moulded manufacturing, same owned Canadian shop floor — and the CS-580 is where that stack meets the least glamorous, most regulated work on the water.

The doctrine's civil half applies in full: radio and GNSS are permitted on this line — a harbour cleanup is not a jammed battlespace — and the boundary is published in both directions so no buyer has to guess. The manufacturing thesis shows up as the blades: mesh cassettes and liners are moulded consumables off the group's own line, which means every working CS-580 keeps buying from the Canadian floor that built it. And the fleet's sovereignty argument lands here as auditability — a collection machine whose every load is logged is a machine a municipality, an insurer and a regulator can all sign off on.

The Water Trio

Skimmer finds it. Recovery lifts it. Dredger cuts it.

Three craft on one shared shallow-draft hull and station-keeping library: the CS-520 is the information layer, the CS-580 the collection layer, and the CS-570 the excavation layer. One incident, one family, one custody chain — from the spill edge to the licensed transfer.

Deployment

A Working Cycle on the Water.

One trailer, one shore station, a loop that closes on the cassette — illustrative of how the craft is used, not a job record.

01 · Arrive & Cue

Launch on the Survey

The craft splashes at the ramp with booms folded and takes its tasking from the information layer: the Skimmer's survey marks where the material is, and the Recovery goes where it is sent. The funnel deploys to its 1.5 m front, the shore station stands up beside the ramp, and the craft works in high-vis posture — lights, reflector and a civil paint scheme. A work boat that wants to be seen.

02 · Work the Field

Sweep Until Full

The craft runs slow lanes through the debris field, and the channel does the work — mouth to channel to cassette, water through, solids stay. Snags shed at the boom, clogs stop collection but never the craft, and nothing ever goes back overboard. Load and level sensing under the seat closes the loop on capacity, not on a timer: full is the trigger.

03 · Offload & Repeat

Swap, Log, Return

The cycle ends at the custody boundary and starts again about five minutes later. The sealed cassette comes out as one lift and enters the licensed chain, logged end to end; an empty cassette and a fresh battery go in on the same dwell. Wash-down stays honest — decon effluent is treated as the regulated waste it is.

The Water Trio · At a Glance

One Hull Library. Three Layers.

The Recovery is the collection layer of the water trio — three craft on one shared shallow-draft hull and station-keeping library, splitting one incident into information, collection and excavation. Same canon, different jobs.
