Kansarmax vs Panamax – who wins in 2026?

📊 Subscribe to the Ship Universe Weekly Newsletter

The workhorses of mid-size dry bulk, Panamax and Kamsarmax, sit at the crossroads of grains, coal and bauxite. Specs look similar on paper, but tiny constraints (beam, draft, LOA) determine where they can load, how much they lift, and whether a voyage clears profit after canal, port and fuel realities. With 2026 shaping up as a heavy delivery year, owners and charterers need a lane-by-lane view rather than a single “winner.”

Panamax vs Kamsarmax — Fast Specs

Quick “can it fit?” guide before you model TCEs.

Spec Panamax Bulker Kamsarmax Bulker
Typical DWT band ~65,000–80,000 dwt ~80,000–82,000 dwt (Panamax subset)
Max LOA used in practice ≈ 294 m (original Panama locks) ≈ 229 m (Port Kamsar LOA cap)
Max beam (legacy canal) ≈ 32.31 m ≈ 32.2–32.3 m
Max draft (TFW reference) ≈ 12.04 m Similar (design-series dependent)
Typical cargos Grain, coal, iron ore, minor bulks Grain, coal, bauxite (+ some hot coils)
Port/channel access highlight Legacy Panama dimensions → routing options Purpose-built for Kamsar stems in Guinea
Port fit tip
LOA/air-draft/draft checks first; Kamsarmax is binary for Guinea bauxite, Panamax wins on cross-canal optionality.
Cargo mix note
Both lift grains/coal; Kamsarmax’s slightly larger parcel helps on long Atlantic→Asia hauls.

Demand Drivers to 2026 — What Moves Tonne-Miles

Grains, bauxite and coal signals framed for mid-size bulkers.

Grains
Long-haul bias
  • South Atlantic crops (Brazil/Argentina) + Asia demand support long legs.
  • Seasonality and congestion swing laycans; watch harvest windows.
2026 tonne-mile tilt
Favours Kamsarmax ≳ Panamax on $/t for long Asia legs.
Bauxite
Structural growth
  • Guinea exports feed Chinese alumina/aluminum capacity.
  • Berth/river windows + LOA compliance control liftings.
2026 tonne-mile tilt
LOA at Kamsar makes Kamsarmax the natural fit.
Coal
Mixed
  • Overall softer outlook; India/SEA pulls add regional support.
  • AUS/ID → India/SEA and intra-Asia legs sustain mid-size activity.
2026 tonne-mile tilt
Panamax & Kamsarmax split; port/draft decide.
What to watch
Harvest outcomes, Chinese restocking cycles, weather-linked delays in West Africa and La Plata.
Pricing nudge
Longer average hauls convert flat cargo growth into tonne-mile gains—helpful for mid-sizes.

Orderbook Pressure — Deliveries Landing by 2026

Shares are indicative by DWT; focus on what it means for mid-size earnings.

Panamax (incl. Kamsarmax)
≈33.9%
Supramax/Ultramax
≈28.3%
Capesize
≈23.9%
Rate pressure lens
Higher mid-size delivery concentration increases competition for stems; slow-steaming and recycling moderate effective supply.
Where Kamsarmax holds
In Guinea/Brazil → China trades, the slightly larger parcel helps defend TCEs vs. Supras nibbling at smaller-port stems.
Owner watchlist
  • Speed policy & weather routing settings (effective supply).
  • Scrap prices & demolition appetite (removes older Panamaxes/Supras).
  • Yard delivery slippage and retrofit yard congestion.

Panama Canal — Where We Are vs 2023–24

Quick operator snapshot: slots, draft, and fee tone.

Daily transit slots
Up to 36/day
Raised from drought-era floors; actual 2025 flows often ~33–35/day. (Reuters)
Max draft (Neopanamax)
49 ft authorized
49.0 ft (14.94 m) in effect since Aug 2024 with rains. (ACP)
Fee environment
~15% lower vs 2024
2025 tolls eased vs 2024; demand still below the 36/day cap. (Reuters)
Routing implication
Slots are back, but realized transits still fluctuate below the cap. Keep Cape/Suez diversion models handy for backhauls.
Budgeting cue
Run a “with/without Canal” comparison: reserved slot vs. queue risk, plus fuel/time for detours.

Kamsarmax vs Panamax — Lane by Lane (2026)

Use this as a pre-fixture sense-check; confirm berth/draft locally.

Guinea (Kamsar) → China — Bauxite
Winner: Kamsarmax
LOA cap (~229 m) + structural bauxite growth; design fit is decisive.
Brazil/Argentina → Asia — Grains
Edge: Kamsarmax
Long hauls and slightly larger parcels improve $/t; port fit usually similar.
AUS/Indonesia → India/SEA — Coal
Split
Regional demand persists; draft/berth specifics decide fixture class.
US Gulf / ECSA → Europe (Canal optional)
Edge: Panamax
When slots/fees pencil, legacy dimensions keep routing optionality broad.
Atlantic ↔ Pacific — Backhauls
Edge: Panamax
If queues are light and auctions subdued, Panamax flexibility can nudge utilization.

Owner Playbook — 2026 Setup

Practical knobs to defend TCEs and compliance.

TCE sensitivity — quick view
Illustrative uplift/drawdown levers. Use your numbers, but the relative direction holds.
+ Voyage distance / tonne-miles (grains, bauxite)
± Canal slot & fee regime
− Effective supply (speed policy, recycling)
CII / EEXI health check
  • Re-baseline CII with actual 2025 ops (speed, weather routing, waiting times).
  • Confirm EEXI tech files and engine power limitation documentation are audit-ready.
  • Plan margin for bad weather/queues to avoid CII letter grade slippage.
Retrofit levers
  • Scrubber economics: only if your trade has persistent high HSFO–VLSFO spreads and port calls allow operations.
  • Props/ducts/bulb tweaks: small capex but real fuel savings on steady lanes.
  • ALT-fuel readiness: wiring/space for methanol or LNG-adjacent auxiliaries if yard slots align.
Commercial play
  • Lean into Atlantic→Asia seasons (grains) and Guinea bauxite windows.
  • Keep a backhaul map that toggles Canal on/off with conservative queue time bands.
  • Watch Supras nibbling at smaller-port stems; defend parcel size where you can.
Update quarterly: harvest outcomes, ACP advisories, yard congestion, and demolition prices can change the calculus fast.

Bottom line: 2026 doesn’t crown a single champion so much as it rewards the ship that’s in the right lane at the right time. With grains and Guinea bauxite still pushing long-haul tonne-miles, Kamsarmax keeps a slight edge on the Atlantic→Asia runs, while a more normalized, but still variable, Panama Canal keeps Panamax relevant where routing optionality matters.

For owners and charterers, it is encouraged to keep a living routing model that toggles Canal on/off, protect parcel economics on grain/bauxite peaks, and defend your CII/EEXI margin with pragmatic speed and retrofit choices.
