Buying a Ship in War Sails? 7 Essential Tips for New Captains – Mount & Blade II: Bannerlord

The promise of commanding your own fleet in Mount & Blade II: Bannerlord’s Naval Warfare expansion (often called War Sails by the community) is an enticing prospect. After witnessing epic ship-to-ship battles, the call of the open sea and the lure of maritime dominance are strong. However, transitioning from a land-based warlord to a successful naval captain requires more than just buying a boat and hoisting a sail. The economic and strategic realities of naval warfare in Calradia are deep and unforgiving. Based on extensive gameplay analysis, this guide details the seven most critical lessons you must learn before investing in your first vessel. Adopting this knowledge early will prevent your campaign from sinking under the weight of debt and poor planning, setting you on a course for true maritime supremacy.

1. Patience is Your Greatest Asset: Do NOT Buy a Ship Too Early

This is the single most important piece of advice, and it cannot be overstated. In Bannerlord, a ship is not merely a vehicle; it is a significant, ongoing financial liability. The initial purchase price is just the beginning. You must also pay regular maintenance costs to keep your vessel seaworthy, akin to troop wages but for your fleet.

The golden rule? Do not even consider purchasing a ship until you have a minimum of 50,000 to 100,000 denars in stable reserve, and even that is early. A more comfortable benchmark is Clan Tier 3 and upwards of 150,000 denars. Why such a high barrier?

• Exorbitant Costs: The ship economy is scaled for the late game. A basic skiff holding 20-30 troops can cost over 12,000 denars. The larger, formidable warships capable of carrying 150+ troops can cost well over 150,000 denars each.
• The “B.O.A.T.” Rule Applies: The old adage “Break Out Another Thousand” is painfully accurate here. Maintenance fees will continuously drain your treasury, whether you’re in a thrilling battle or idling in port.
• No Immediate ROI: Unlike a productive workshop or a skilled caravan, a ship does not generate passive income. It is a tool for combat and transportation, and finding profitable naval engagements (which we’ll cover next) is not a guaranteed or quick process.

What to Do Instead: Focus on strengthening your land-based position. Build your renown, increase your clan tier, establish a stable income through workshops, caravans, and successful land battles. Use the Custom Battle menu to safely scratch your naval itch and, more importantly, to practice the complex mechanics of sailing, wind management, and naval combat without risking your campaign’s economy. This foundational stability on land will fund your eventual dominance at sea.

2. The Vast Emptiness: Naval Encounters Are Rare and Strategic

You’ve secured your financial foundation and purchased your first ship, eager for epic, large-scale fleet battles. It’s crucial to adjust your expectations: the open seas in Calradia are vast, and major naval battles are strategic events, not common occurrences.

Unlike land travel, where terrain funnels armies into predictable choke points, the ocean offers immense space. You can sail for hours of gameplay without encountering a worthy adversary. This isn’t a design flaw but a reflection of realistic naval warfare; historically, finding an enemy fleet on the open ocean was a challenge in itself.

• The Haystack and the Needle: Your campaign map is the haystack. Enemy warships, the prized needles, are often tied to faction armies or patrols near their coasts. While hunting down small bands of Sea Raiders or lone merchant skiffs is relatively straightforward, seeking out a climactic, decisive fleet battle requires patience and intent.
• Strategic Positioning is Key: Naval power shines in control and projection. Use your fleet to:
  • Rapidly move your army along coastlines, bypassing land threats.
  • Intercept enemy armies attempting to cross straits or narrow seas.
  • Lay siege to coastal settlements from the seaward side.
  • Protect your own trade routes and raid those of your enemies.
    The battle itself may be the climax, but its value is determined by the strategic objective it achieves.

The Takeaway: Do not buy a fleet expecting constant action. Buy it to exert strategic control over maritime regions. Your ship is a tool for map-wide influence, and the occasional breathtaking battle is the rewarding result of that strategy, not the daily grind.

3. Size Matters: Ship Class Determines Your Role

In naval combat, the class of your ship dictates its capabilities and its role in your fleet. This isn’t just about carrying more men; it’s about fundamental combat functions.

• Small Ships (Skiffs, etc.): These are scouts, harassers, and auxiliaries. They are agile and cheap but cannot ram. Their primary value is in providing supporting missile fire, boarding already-engaged larger vessels, or running down fleeing enemies. They are vulnerable to a single solid ram from anything larger.
• Medium & Large Ships (Galleys, Dromons, etc.): These are the line fighters and commanders of your fleet. They can mount rams, which are devastating offensive weapons capable of crippling or sinking smaller vessels in a single hit. They carry more troops, have higher durability, and their height gives missile troops an advantage. However, they are slower to maneuver and a significant financial loss if sunk.

Building a Balanced Fleet: A smart admiral builds a combined arms fleet. Consider a core of 1-2 large flagships loaded with your best infantry and archers, supported by several smaller, faster ships to flank, harass, and prevent enemy maneuvers. Putting all your gold into one massive, slow ship can leave you vulnerable to being surrounded and boarded by a swarm of smaller, cheaper vessels.

4. Master the Wind: It’s Your Invisible Army

If ship size provides the muscle, then the wind is the intellect guiding your fleet. In Bannerlord‘s naval combat, wind strength and direction are not atmospheric decorations; they are the most powerful and consistent tactical factors on the battlefield. Ignoring them is a direct path to defeat.

• The Wind Gauge is Your Command Screen: Your interface provides clear wind indicators: ripples on the water, fluttering flags, and a crucial wind gauge (often in the lower-right corner). Green indicates sailing with the wind (fast). Red indicates sailing against the wind (slow or stagnant). Mastering your angle to the wind is as important as positioning your infantry on a hill.
• The “Weather Gage” is a Real Advantage: This historical naval term applies perfectly here. Having the windward position (upwind of your enemy) grants you the tactical initiative. You can choose when to close the distance and attack. An enemy positioned downwind of you is at a severe disadvantage, struggling to sail against the wind to reach you while you pepper them with missiles or prepare a devastating ramming run.
• Sails vs. Oars: Knowing Your Tools:
  • Square Sails: Provide tremendous speed when running directly with the wind. Use them for long approaches or rapid disengagements on a favorable wind.
  • Lateen Sails: Are more versatile, catching wind from a wider angle. They are essential for maneuvering and maintaining speed when you cannot sail directly downwind.
  • Oars: Provide slow, consistent power independent of the wind. They are vital for precise maneuvers in battle, for moving when the wind is against you, or for holding a static position to unleash missile volleys.

Tactical Application: A classic beginner strategy is to “sail upwind first.” Approach a battle by sailing into the wind (the hard part) to position yourself windward of the enemy. Once engaged, you can then turn to run downwind for a powerful, high-speed ramming attack or a swift retreat. An enemy force trying to fight upwind toward you will be slow, predictable, and exhausted by the time they reach your lines.

5. Ranged Dominance: Control the Space Between Ships

The meta of land combat in Bannerlord—that ranged units are powerful—is amplified tenfold on the high seas. In the chaotic, movement-focused arena of naval battles, archers, crossbowmen, and skirmishers are your primary damage dealers.

• The Standoff Phase: Before ships entangle for boarding, there is often a prolonged period of maneuvering and missile exchange. A ship loaded with high-tier archers can decimate an enemy’s deck crew, weakening them significantly before any melee begins.
• Denying Boarding Actions: A savvy tactic is to use your ship’s mobility (guided by wind) to stay close to an enemy vessel but just out of boarding range, creating a “kill zone” where your archers can fire with impunity while the enemy’s infantry stand idle.
• Ammunition is a Factor: Unlike land battles, you cannot retrieve arrows from the fallen. Managing ammunition adds a layer of depth. Some ships offer upgrades for additional ammunition, and your main character can often find resupply points on deck. Planning a volley-fire approach or focusing fire to eliminate key enemy missile troops first becomes crucial.
• Cultural Considerations: This dynamic naturally disadvantages factions like the Sturgians (Nords), whose strength lies in melee infantry. Without a strong ranged complement or clever tactics to close the gap quickly, their ships can be whittled down before they ever get to swing an axe.

The Takeaway: When outfitting your flagship, prioritize filling its complement with high-quality ranged troops. Your boarding infantry are essential for the final blow, but your ranged units are what will create the opportunity for that blow to land safely and decisively.

6. Strategic Foundations: Character Builds & Companions for the High Seas

Your success on the waves begins long before you purchase a ship—it starts in character creation. Bannerlord’s Naval DLC introduces new skill dynamics that require foresight. Building a land-locked powerhouse will leave you floundering as an admiral.

• The New Naval Skills: Three primary skill trees govern maritime prowess:
  • Mariner: Governed by Vigor and Endurance. This is your personal combat effectiveness on a ship. It improves your movement speed, attack speed, and accuracy while aboard. Think of it as your “sea legs” combat skill.
  • Shipmaster: Governed by an average of Control and Cunning. This is your command skill for the fleet. It impacts crew morale, post-battle recovery speed, and overall ship efficiency during campaigns on the world map.
  • Bosan (Boatswain): Governed by Intelligence and Social. This is your engineering and logistics skill. It affects ship repair rates, maintenance cost reduction, and other campaign map efficiencies for your fleet.
• The Early Choice Conundrum: During character creation, you’ll select background options (like “sailor” or “river rat”) that grant starting points in these skills. This presents a classic Bannerlord trade-off: do you invest early focus points in skills you’ll use constantly on land (like One-Handed or Leadership), or in Naval skills you may not use for dozens of hours? There is no perfect answer, but if a long-term naval campaign is your goal, dedicating 1-2 initial focus points to Shipmaster or Mariner can pay significant dividends later.
• Companions as Specialists: You cannot be everywhere. Recruit companions to act as specialized ship captains. A companion with high Shipmaster can command a wing of your fleet, while one with high Bosan can be assigned to reduce the overall maintenance of your armada. This allows your main character to focus on their own combat (Mariner) and overall army command.

Planning is Key: Decide early if your campaign has a naval destiny. If it does, your attribute point allocation (favoring Vigor/Endurance for Mariner, Control/Cunning for Shipmaster) and early background choices must reflect that ambition.

7. Command & Control: You Are a Fleet Admiral, Not Just a Captain

The final and most important leap in mindset is understanding that in a naval battle, you command the entire fleet, not just your flagship. Your personal heroism is secondary to the tactical positioning of your ships.

• Pre-Battle Deployment: Before battle, you assign troops to specific ships. This is where strategy is born. Do not auto-assign.
  • Create dedicated Archer Ships (loaded with your best ranged troops) to stand off and provide fire support.
  • Create dedicated Boarding Ships (loaded with heavy infantry) to close and capture enemy vessels.
  • Your Flagship should be a balanced or command-oriented vessel, often holding reserves.
• In-Battle Commands: While you can personally take the helm of one ship for a thrilling ramming attack, your primary role is as the strategic overseer.
  • Use the command menu to give orders to other ships in your fleet: Engage (skirmish at range), Charge (close for boarding), Follow Me, or move to a Specific Position on the water.
  • Control the engagement pace. Use your Archer Ships to soften a target before sending in your Boarding Ships for the coup de grâce.
  • Manage the wind for your entire fleet. Position your Archer Ships upwind so they can control engagement; send your Boarding Ships on a downwind slamming attack.
• The Limitation of Reinforcements: Crucially, only a limited number of your ships deploy at the start of a battle (similar to troop reinforcement waves on land). The ships you begin the battle with are your only immediate tools. Choosing the right composition for your initial battle line is a critical decision.

Set Sail with Knowledge

Embracing naval warfare in Mount & Blade II: Bannerlord is one of the most rewarding end-game evolutions. It transforms the strategic map and offers breathtaking combat. However, the path to maritime dominance is built on patience, strategic investment, and specialized knowledge.

Recap Your Voyage Plan:

1. Build a land-based economic fortress first.
2. Understand that naval power is about strategic control, not constant battle.
3. Build a balanced fleet where ship size dictates role.
4. Respect and master the wind—it is your greatest ally or deadliest foe.
5. Embrace ranged dominance to control the seas.
6. Build your character and companions with naval skills in mind from the start.
7. Command your fleet as an admiral, not just a hands-on captain.

By internalizing these seven pillars, you will not fall prey to the common pitfalls that leave aspiring admirals bankrupt and marooned. Your fleet will not be a financial sinkhole, but a formidable instrument of conquest. Now, captain, the horizon awaits. Set your course, trim your sails, and prepare to leave your mark on the history of Calradia—from the sea.
