📄 Charter Party Contracts Explained: Key Agreements in the Chartering Business

My name is Davide Ramponi, I’m 20 years old and currently training as a shipping agent in Hamburg. On my blog, I take you with me on my journey into the exciting world of shipping. I share my knowledge, my experiences and my progress on the way to becoming an expert in the field of Sale and Purchase – the trade with ships.

But besides buying and selling ships, another crucial pillar of the maritime industry is chartering – and at the heart of every charter agreement is the charter party contract. Whether it’s a one-time voyage, a time-based charter, or a long-term bareboat deal, everything hinges on the correct use and understanding of these contracts.

So, what exactly is a charter party? What types are commonly used, and what clauses should you never overlook? In this blog post, I’ll walk you through the basics and deeper insights of charter party contracts, help you understand key clauses, and share tips on avoiding common pitfalls when negotiating them.

What Is a Charter Party? A Fundamental Maritime Contract

A charter party (often abbreviated as “C/P”) is a legal contract between the shipowner and the charterer. It outlines the terms and conditions under which a vessel is hired, including the type of charter, the duration, cargo details, costs, and liabilities.

In simple terms:

⚓ The owner provides the ship.

📦 The charterer provides the cargo (or operations).

📜 The charter party governs how both parties work together.

Depending on the charter type, responsibilities for crew, fuel, port fees, and cargo handling can vary significantly. That’s why choosing the right type of contract is critical.

Types of Charter Party Contracts: Gencon, NYPE and More

There are several types of charter party agreements, each serving a different operational purpose. Let’s explore the most common ones:

🛳️ 1. Voyage Charter Party

In a voyage charter, the shipowner agrees to carry cargo from port A to port B for a single or limited number of voyages.

• Owner pays for fuel, port charges, and crew.

• Charterer pays a freight rate (often per ton of cargo).

• Common form: GENCON (developed by BIMCO – Baltic and International Maritime Council).

📌 **Use Case:** Best for one-off shipments or seasonal cargo transport.

🕰️ 2. Time Charter Party

In a time charter, the charterer hires the vessel for a specific period of time (e.g., 6 months, 1 year).

• Charterer pays hire based on time (e.g., per day).

• Charterer is responsible for voyage costs like fuel and port dues.

• Owner maintains the ship and crew.

Common form: NYPE (New York Produce Exchange form) – one of the most widely used time charter forms globally.

📌 Use Case: Ideal for companies needing flexible vessel control over a set period.

🚢 3. Bareboat Charter Party

In a bareboat charter, the ship is leased without crew, insurance, or supplies.

• The charterer assumes full operational control.

• Often used for long-term contracts or financing arrangements.

• Can resemble vessel leasing more than short-term hire.

📌 Use Case: Suited for companies wanting full control and ready to take on operational risks.

GENCON vs. NYPE: Understanding Standard Contracts

While there are many custom charter parties in use, GENCON and NYPE remain the industry’s foundational forms. Let’s compare them:

Feature	GENCON (Voyage)	NYPE (Time)
Charter Type	Voyage Charter	Time Charter
Payment	Freight (per ton/cargo)	Hire (per day)
Costs Covered By	Owner (fuel, port, crew)	Charterer (fuel, port fees)
Flexibility	Limited to specific voyage	More operational flexibility
Duration	Single or limited voyage	Set period of time
Risk	Owner assumes voyage risks	Charterer assumes voyage risks

💡 Key Insight: GENCON focuses on delivery from point A to B, while NYPE gives the charterer more control and flexibility over how the vessel is used.

Important Clauses to Watch: What Every Charter Party Must Include

Regardless of the form used, all charter party contracts should clearly define several critical clauses. Here are the most important ones:

🕒 1. Delivery and Redelivery

• Delivery Clause: Specifies where and when the charterer will take possession of the vessel.

• Redelivery Clause: Defines the return point and time.

⏳ Disputes often arise if delivery/redelivery windows are too tight or unclear.

⚓ 2. Loading and Discharge Term

• Includes loading/discharge ports, laytime (allowed time), and loading rates.

• Critical for voyage charters, where delays can lead to demurrage claims.

💸 3. Demurrage and Despatch

• Demurrage: Penalty paid by the charterer for exceeding laytime.

• Despatch: Bonus paid by the owner if loading/discharging is completed early.

⚠️ These clauses are highly sensitive and often subject to disputes. Accurate time logging is essential.

📄 4. Off-Hire Clause (Time Charters Only)

• If the vessel becomes unavailable (e.g., breakdown), the charterer doesn’t pay hire during that time.

🌍 5. Trading Limits and War Risks

• Defines where the vessel can go and what risks the owner is not willing to accept (e.g., sanctioned ports or war zones).

🛠️ 6. Maintenance and Seaworthiness

• Obligates the owner to provide a seaworthy ship and maintain it throughout the charter.

Common Mistakes in Charter Party Agreements (And How to Avoid Them)

Charter party contracts are complex—and even experienced professionals can make costly errors. Here are a few common mistakes to watch out for:

❌ 1. Vague Delivery Windows

Unclear delivery dates can lead to disputes, idle time, and missed cargo slots.

✅ Tip: Always specify delivery date ranges and ports in detail.

❌ 2. Incomplete Clauses

Failing to include key clauses—like off-hire, weather exceptions, or war risks—can leave parties exposed.

✅ Tip: Use standard templates like BIMCO’s and have a maritime lawyer review the final draft.

❌ 3. Ignoring Local Regulations

Ports or countries may impose special rules that override contract terms.

✅ Tip: Consult with local agents or P&I clubs to ensure compliance.

❌ 4. Misunderstanding Demurrage Rules

Many charterers underestimate how quickly demurrage charges can accumulate.

✅ Tip: Log laytime accurately and communicate delays immediately.

Tips for Negotiating and Customising Charter Parties

No two charter parties are the same—and even standard forms require careful adjustment. Here’s how to make sure your agreement reflects your needs:

🧩 1. Start with a Standard Form, Then Tailor

Use widely accepted templates like GENCON, NYPE, or BARECON. These provide a solid legal framework—but don’t forget to adapt them to your operational needs.

🤝 2. Clearly Define Responsibilities

From fuel costs to crew provisions, clarity avoids conflict. Spell out who pays what, and when.

🛡️ 3. Allocate Risks Transparently

All contracts involve risk. The key is to balance it fairly and agree upfront on what happens in worst-case scenarios (e.g., mechanical failure, port congestion).

🔍 4. Review With Legal and Broker Support

A trusted broker can highlight commercial gaps. A lawyer ensures enforceability. Together, they help you protect your position without overcomplicating the deal.

✍️ 5. Negotiate Flexibility Where Needed

If market conditions are uncertain, include clauses for:

• Voyage cancellation

• Charter extension

• Fuel cost adjustments

Flexibility can save both parties time and money down the line.

Conclusion

Charter party contracts are at the heart of the chartering business. Whether it’s a simple voyage from A to B or a multi-year time charter, the terms of the agreement determine profitability, risk, and operational success.

Understanding the different charter types—GENCON for voyage, NYPE for time, and BARECON for bareboat—is essential for anyone in the shipping world. Add to that a strong grasp of key clauses and a careful, negotiated approach, and you’ll be well equipped to handle even the most complex charter deals.
