Maratha Maritime Power and Naval Strategy

The Land Empire That Built a Fleet: Sea Power as Sovereign Statement

Most land-based powers treat the coastline as an edge — the place where territory stops. Shivaji treated it as a frontier to be controlled. In the 1650s and 1660s, when the Maratha state barely existed on paper, Shivaji began constructing an ocean-going fleet and a chain of coastal fortifications that by his death in 1680 amounted to the first indigenous Indian naval power capable of contesting the sea-lanes the Portuguese and British East India Company depended on. This was not opportunistic or accidental. It was a strategic decision grounded in a specific insight: that sovereignty on the Konkan coast — the thin strip of territory between the Sahyadri mountains and the Arabian Sea that was Maratha heartland — could not be secured from the land alone.

The plain version: if your enemy can sail up your coastline and tax your ports, you are not sovereign. You are a tributary. Building a navy was a declaration that Shivaji intended to be sovereign, not just independent.

The Fleet: Design and Command Philosophy

The Maratha naval doctrine was built around the galbat — a shallow-draft, fast, maneuverable vessel of 40-70 tons, carrying 4-8 guns, designed specifically for the Konkan coast with its rocky inlets, monsoon swells, and tactical geography. The galbat was not built to defeat Portuguese or Dutch ocean-going warships in deep-water engagements. It was built to control the coastal zone — to intercept supply ships, threaten ports, escort Maratha vessels, and operate in conditions where heavier European ships were at a disadvantage.¹

This was an architectural decision with strategic logic: the Maratha navy was not designed to be a universal sea power but to be dominant in the specific maritime zone the Maratha state depended on.

The command structure reflected Shivaji's broader administrative philosophy. Naval commanders were not drawn exclusively from any single community. Daulat Khan, a Muslim, served as one of the senior fleet commanders. Darya Sarang was another commander of note. Mainak Bhandari, from the Bhandari fishing community — people who had lived on the sea for generations — commanded significant portions of the fleet. This deliberate multi-community structure was not sentimental diversity; it was strategic. The Bhandari community had the navigational knowledge and seamanship that inland Maratha warriors lacked. The Muslim commanders brought legitimacy with coastal Muslim trading communities. The fleet's effectiveness depended on drawing expertise from whoever had it.¹

The Island Forts: Sindhudurg as Paradigm

The naval strategy was inseparable from a program of coastal fort construction that ran throughout the 1660s. Sindhudurg — built on a rocky island in the Arabian Sea off the Malvan coast — is the paradigm case. Its specifications were extraordinary: 48 acres of fortified area, 52 bastions, 3 years of construction, at a cost of approximately 1 crore hons. The construction required sinking foundation stones in the ocean, engineering freshwater sources within the island perimeter, and designing walls that could absorb cannon fire from the sea.¹

Sindhudurg was not just a military installation. It was a political statement encoded in stone: a permanent Maratha presence at sea, impossible to evict without a sustained naval siege that neither the Portuguese nor the Mughals were willing to mount. Vijaydurg and Suvarnadurg served similar functions at different points along the coast, creating a chain of secure bases from which the fleet could operate without depending on vulnerable shore facilities.

The island fort architecture also solved a critical vulnerability of land-based fortifications: they could not be surrounded and starved out in the same way. A fleet at anchor inside Sindhudurg's harbor had a base of operations that no land army could threaten.

The Surat Connection: War Economics as Naval Finance

The 1664 Surat raid — in which Maratha forces extracted 1–1.5 crore rupees from the richest trading port on the western Indian coast — had a direct relationship to naval expansion that Purandare makes explicit. The loot from Surat financed Sindhudurg's construction. The economics were circular: the maritime threat that the navy was being built to address was itself the source of the capital that funded the navy's construction.¹

This is the Sun Tzu logic of the "economics of war" applied to naval state-building: the enemy's resources transfer to the victor. The Surat traders and merchants — who included representatives of every major trading house in the Muslim world — provided involuntarily the funds for the fortress that would permanently alter the balance of naval power in their trading zone.

The second Surat raid (1670) extracted an additional 66 lakh rupees (Mughal estimate). By this point the naval program was fully funded and Sindhudurg was operational.

The Basrur Campaign: Naval Force Projection

In February 1665, Shivaji mounted an amphibious operation at Basrur on the Karnataka coast with 85 frigates and 3 great ships — the largest Maratha naval force documented in the historical record. This was not a coastal defense operation but a projection of naval power into territory south of the Maratha heartland, demonstrating the fleet's ability to extend force well beyond Sindhudurg's immediate zone.¹

The Basrur campaign established that the Maratha navy was not a coastal patrol fleet but an instrument capable of strategic offensive operations. This had implications for Shivaji's southern territorial expansion in the 1670s, where the navy could support and supply land operations that would otherwise have been logistically impossible.

Evidence and Tensions

[POPULAR SOURCE] — Purandare does not cite primary sources for fleet size, fort specifications, or construction costs. The 48 acres / 52 bastions figures for Sindhudurg are consistent with other accounts but should be treated as plausible rather than definitively verified. The naval commanders' names (Daulat Khan, Darya Sarang, Mainak Bhandari) are drawn from Marathi chronicle traditions.¹

Tension with the land-power paradigm: The decision to build a navy when the state's core territory and military strength was land-based is a non-obvious strategic choice. Purandare frames it as Shivaji's forward vision, but it could equally be read as a response to specific threats (Portuguese interference with Maratha coastal trade and pilgrimage routes) rather than a proactive strategic doctrine. Whether the naval program was doctrine or reactive is unclear.

Cross-Domain Handshakes

History — Sun Tzu Economics of War: Sun Tzu — The Economics of War — Sun Tzu's forage principle ("1 cartload of enemy provisions is worth 20 of your own") and the argument that conquered resources transfer to the victor describes exactly the Surat-to-Sindhudurg financing loop. What the Maratha case adds: this principle can operate across a time lag — the extracted resources don't need to fund the immediate battle; they can capitalize the infrastructure required for future operations. The Surat loot funded naval construction that only became operationally significant years later. This suggests the economics-of-war logic can be a multi-year strategic investment program, not just a field-level foraging tactic.

History — Arthashastra State Enterprises: Arthashastra — State Enterprises — Kautilya lists strategic assets in priority order (farms/pastures/mines/forests/workshops); maritime capacity does not appear explicitly in his taxonomy, but the state-as-entrepreneur logic is identical. Shivaji's fleet was a state enterprise in exactly Kautilya's sense: capital-intensive, strategically essential, staffed with specialized labor (Bhandari navigators), operating under state direction. The parallel illuminates what Kautilya's framework misses: maritime power as a state-enterprise category that was invisible from the landlocked Mauryan perspective but essential in the coastal Deccan context.

The Live Edge

The Sharpest Implication Naval power is a proxy for the completeness of sovereignty. A state that controls its land but not its coastline is not fully sovereign — it is a land jurisdiction that pays rent to whoever controls the sea. Shivaji's decision to build a navy in the 1650s, when the Maratha state was barely legitimate by any conventional measure, is a statement about what sovereignty requires that most political entities never confront. Most states inherit their coastline's status from prior treaties and balances of power. Shivaji had to build his from scratch, and the construction cost was explicit in a way that inherited sovereignty is not. The implication: every sovereign entity that cannot project force to its own coastline is depending on someone else's restraint rather than its own capability. That is a different and more fragile kind of security than it appears.

Generative Questions

Is the galbat design — optimized for the specific coastal geography of the Konkan — a universal principle (build your naval force for the specific waters you need to control, not for abstract naval supremacy) or a historical accident of the available technology? Does the same logic appear in other coastal state-building projects (Ottoman, Vietnamese, Dutch)?
The Maratha fleet included Muslim commanders at senior levels while the Mughal empire used Hindu and Muslim commanders interchangeably. Both sides treated military competence as domain-spanning across religious identity. Does the multi-community command structure appear as a strategic choice in the historical record, or is Purandare reading a modern sensibility backward into 17th-century practice?
Sindhudurg cost 1 crore hons to build and was never successfully taken by assault. What is the cost-effectiveness calculation for island fortification versus land fortification, and when does island fortification become the dominant design choice in historical practice?

Open Questions

Are there Persian, Portuguese, or British East India Company records documenting the Maratha fleet's size and operational capability that could corroborate Purandare's figures?
How did the galbat's design compare with contemporaneous Omani, Ottoman, or Malabar coastal vessel designs? Was it indigenous innovation or adaptation of an existing regional tradition?
What happened to the Maratha navy after Shivaji's death? Did the institutional knowledge survive, or was it person-dependent?
