The sources
Ships are expensive, long-lived, mobile assets with volatile earnings — a combination that makes financing them a specialist discipline. The capital structure an owner chooses determines not only cost but operational freedom, because lenders attach conditions to how the ship is run.
| Source | Typical structure | Characteristics |
|---|---|---|
| Senior bank debt | Mortgage-secured term loan | Lowest cost; strongest covenants; conservative advance rates |
| Leasing (Chinese, Japanese and others) | Sale and bareboat charter back with purchase options | High advance rates; longer tenor; embedded cost |
| Sale and leaseback | Asset sold, chartered back | Releases capital; owner loses residual upside unless optioned |
| Export credit agencies | Newbuilding support tied to yard country | Long tenor; strict eligibility |
| Bonds | Corporate or secured, public or private | For larger, listed or well-known issuers |
| Private credit / mezzanine | Junior or unitranche debt | Higher cost, more flexible, faster |
| Equity | Owner, private equity, public markets | No repayment obligation; expensive in dilution |
The bars represent relative cost of capital; the line represents relative flexibility. There is no free lunch: cheaper capital comes with tighter control.
The covenants that matter operationally
Finance documents are not only about money. They constrain how the ship is managed.
| Covenant | Typical requirement | Operational consequence |
|---|---|---|
| Loan-to-value / minimum value | Vessel value must exceed a multiple of outstanding debt | Falling asset values trigger cash or prepayment |
| Approved manager | Manager must be acceptable to the lender | Constrains choice of ship manager |
| Flag and class | Approved registries and class societies only | Constrains reflagging |
| Insurance | Minimum covers, lender as loss payee, notice of cancellation | Broker coordination required |
| Trading restrictions | Excluded areas, sanctions compliance, war risk consent | Affects routing and chartering |
| Maintenance and class status | Vessel kept in class, free of overdue recommendations | Class conditions become finance events |
| Cash sweep / minimum liquidity | Retained cash levels | Constrains distributions |
| Change of control | Consent required | Affects corporate transactions |
| Environmental / ESG | Increasingly: emissions reporting, recycling standards | Compliance data becomes a finance obligation |
The last row is comparatively new and growing. Lenders participating in responsible-finance frameworks require emissions disclosure and, increasingly, responsible ship recycling undertakings — which links finance directly to the Hong Kong Convention regime that entered into force on 26 June 2025.
Why lenders care who manages the ship
A vessel's value depends on its condition, its class status and its trading record. All three are in the manager's hands. That is why "approved manager" clauses exist, and why a change of manager typically requires lender consent.
For owners this cuts both ways: it constrains choice, and it also means a strong manager is a financing asset. Owners refinancing should expect the lender to look at the manager's inspection record as part of the credit assessment.
The market context
UNCTAD reported seaborne trade of 12,720 million tonnes in 2024, up 2.2%, with 2025 growth projected at just 0.5% against a ten-year average of 1.8%. Meanwhile more than 50% of newbuilding tonnage on order is designed for alternative fuels while over 90% of the active fleet still runs on conventional fuel.
Those two facts frame the financing question of the decade: owners must invest in fuel-flexible tonnage during a period of weak trade growth and uncertain regulation. That is precisely the environment in which capital structure decisions determine survival.
Practical guidance for owners
- Model the downside first. Stress the loan-to-value covenant against a plausible fall in asset values, not an optimistic one.
- Read the trading restrictions against your actual trade, including any war risk areas you may need to transit.
- Understand the total cost of leasing, including purchase option pricing, not just the headline rate.
- Keep class status clean. Overdue class conditions can become defaults.
- Align insurance with the finance documents; loss payee and notice provisions are frequently mis-specified.
- Plan for emissions disclosure as a financing requirement, not just a regulatory one.
- Match tenor to asset life and strategy. Short debt on a long asset is how owners get forced sellers.

Frequently asked questions
How are ships usually financed?
Historically by senior bank debt secured on a ship mortgage. Leasing structures, sale and leaseback, bonds and private credit have taken substantial share, particularly for owners who need higher advance rates.
What is sale and leaseback?
The owner sells the vessel to a financier and charters it back on bareboat terms, often with purchase options. It releases capital, at the cost of some residual value and operational flexibility.
Why do lenders approve the ship manager?
Because the manager controls the condition, class status and trading record on which the security's value depends.
Do lenders now require emissions data?
Increasingly yes. Emissions reporting and responsible recycling undertakings feature in many modern shipping finance documents.
