The purchase option is the number hiding inside the bareboat rate
I would not value a bareboat charter by the daily hire alone because the purchase option can quietly decide whether the deal is a lease, a loan, a fleet-control strategy or an expensive rental.
A bareboat charter with a purchase option gives the charterer operating control today and a choice over ownership later. That choice has value only if the option price, vessel market value, financing cost, residual risk and contract restrictions are measured together.
A purchase option inside a bareboat charter is easy to underestimate because the cash does not leave the account on day one. The charterer pays hire, operates the ship, maintains the asset, and keeps the right to buy later. That right may look small until the vessel market moves, shipyard delivery slots tighten, freight rates rise, or the vessel becomes strategically important to the charterer’s cargo book.
The value also cuts both ways. If the option price is below expected market value, the charterer owns a potentially valuable call option on the ship. If the option price is too high, the charterer may simply have expensive operational control with no real acquisition upside. The owner or financier, meanwhile, needs to know whether the option price compensates for residual-value risk and whether the hire schedule is really earning a financing return.
A ship purchase option is worth the discounted difference between expected vessel value and exercise price, plus financing and strategic-control value, minus the costs and restrictions required to reach the option date.
Option value stack for a bareboat charter
A clean valuation does not start with one magic formula. It stacks the option in layers.
Nine questions that decide the option’s real value
① Is the option price below realistic market value at the exercise date?
This is the center of the valuation. If the charterer can buy the ship for $55 million when the vessel is expected to be worth $65 million, the option has obvious intrinsic value. If the option price is close to fair market value, the option may still be useful, but it is more about control than bargain purchase value.
The buyer should build at least three vessel-value cases: downside, base and upside. The option is strongest when it remains useful in the base case and becomes highly valuable in the upside case without destroying liquidity in the downside case.
② Does the hire schedule imply attractive financing?
Many bareboat structures resemble secured vessel financing. The owner or financier owns the asset, the charterer pays hire, and the option price may function like a balloon or residual amount. That is why implied effective rate matters.
If the implied rate is below the charterer’s available mortgage cost, the structure may carry financing value even before the purchase option is in the money. If the rate is high, the option needs stronger asset upside to justify the hire burden.
③ Does the option window arrive early enough to matter?
A purchase option exercisable only at the end of a long charter may have less tactical value than an option that begins after year four or year five. Earlier exercise allows the charterer to convert operating control into ownership if the vessel becomes strategically important.
The earlier window also changes the financier’s economics. A de-escalating price schedule, early exercise fee, make-whole amount, or remaining hire treatment can move value from charterer to owner.
④ Is vessel-price volatility working for the charterer or the owner?
A purchase option becomes more valuable when future vessel values are uncertain and the charterer has the right, but not the obligation, to buy. If values rise, the charterer can exercise. If values fall, the charterer can avoid ownership unless the contract includes a purchase obligation or other economic pressure.
The owner or financier will try to price this asymmetry into the hire rate, option price, return condition, minimum liquidity requirements, or purchase schedule. The charterer needs to know how much it is paying for that upside.
⑤ Are technical costs quietly funding the option?
Under a bareboat structure, the charterer generally controls and pays for vessel operations. That means the charterer may be maintaining the owner’s asset for years before deciding whether to buy it. If the charterer does not exercise, some of that maintenance investment can benefit the owner at redelivery.
The option is worth more when the charterer’s maintenance spend is aligned with a likely acquisition. It is worth less if the charterer may fund major drydock, upgrades and compliance work, then redeliver the ship without owning the improved asset.
⑥ Do ETS, FuelEU and data obligations change the option value?
Emissions compliance can now affect bareboat economics because the operating party, responsible entity, data holder and registered owner may not be the same party. If the charterer controls the ship, the charterer may also control the data and operational choices that shape carbon exposure.
A purchase option is stronger when the compliance file will transfer cleanly into ownership. It is weaker if ETS mandates, FuelEU records, emissions data, biofuel claims, or charter-period obligations create a messy handover at exercise or redelivery.
⑦ Could the option behave like a finance lease on the books?
The accounting question matters because a purchase option that is reasonably certain to be exercised can affect lease classification. That can change leverage optics, right-of-use asset treatment, financing liability presentation and covenant discussions.
The commercial team may call it optional. The finance team may see economic compulsion if the option price is deeply favorable, the vessel is strategically critical, the charterer has funded major improvements, or non-exercise would create a large business loss.
⑧ Is the option cheaper than replacing the ship later?
A bareboat purchase option becomes more valuable when replacement tonnage is scarce, newbuilding delivery is delayed, or the ship has become embedded in a cargo program. The option may let the charterer lock in ownership instead of competing in the secondhand market later.
This is especially important for specialized ships, scrubber-fitted vessels, eco tonnage, gas carriers, offshore units, feeder vessels, or ships with customer-specific suitability. If replacement is difficult, the option deserves a higher strategic value.
⑨ Is walking away actually possible?
A true option gives the charterer choice. But some contracts make non-exercise painful through redelivery conditions, end-of-term repair obligations, make-whole amounts, purchase obligations, indemnities, or operational disruption.
A charterer should value the option lower if walking away is expensive. An owner should value the option higher if non-exercise still leaves the vessel in strong condition with a clear rechartering or sale path.

Valuation table for bareboat option negotiations
The most important issue is not whether the option exists. It is whether the option is economically useful.
| Valuation item | Charterer wants | Owner or financier wants | Negotiation point |
|---|---|---|---|
| Option price Exercise amount |
Price below expected market value at exercise date. | Price high enough to preserve residual return. | Fixed price, de-escalating schedule, market-based formula, or floor. |
| Exercise window Timing of control |
Early and repeated windows that preserve flexibility. | Protection against early loss of expected return. | First exercise date, notice period, make-whole amount, and final expiry. |
| Bareboat hire Embedded financing cost |
Hire that resembles low-cost financing. | Return on capital plus residual-risk compensation. | Implied effective rate, benchmark debt cost, and balloon value. |
| Maintenance Asset condition |
Credit for upgrades if the option is not exercised. | Vessel redelivered in strong condition. | Drydock responsibility, improvement credit, redelivery survey, and records. |
| Compliance ETS, FuelEU, class, IHM |
Clean records that support ownership after exercise. | No stranded liabilities after redelivery or transfer. | Data rights, mandate transfer, emissions records, class files, and indemnities. |
| Downside protection Right not to buy |
True optionality if vessel values fall. | Protection against being left with a weakened asset. | Non-exercise rights, return condition, repair standard, and end-of-term payments. |
Commercial Reality
A bareboat purchase option can be worth millions even if the charterer never exercises it. It can cap replacement risk, preserve fleet control, improve financing flexibility and create bargaining power. But if the option price is too high or the hire already charges for the upside, the option may be more decorative than valuable.
Documents to collect before valuing the option
A proper option valuation needs more than the charter rate and the purchase price.
- Option schedule with first exercise date, final exercise date, notice period, price table, make-whole language and payment mechanics.
- Bareboat hire schedule showing fixed hire, escalation, deferral, balloon economics, reserve accounts and default consequences.
- Vessel valuation deck with current value, projected value, downside value, upside value, broker opinions and newbuild replacement cost.
- Financing comparison against bank debt, sale-leaseback, export credit, private credit and alternative leasing offers.
- Drydock and capex plan covering who pays, who benefits, and whether the charterer receives credit if it does not exercise.
- Redelivery standard covering class status, certificates, technical condition, stores, spares, survey rights and underwater inspection.
- Emissions and compliance file covering ETS, FuelEU, CII, IHM, class, flag, data ownership, mandate transfer and indemnities.
- Accounting memo showing whether the option is reasonably certain to be exercised and whether the lease behaves like finance.
- Exit memo showing whether the charterer would buy, renew, replace, redeliver, sub-charter or walk away under each market case.
Exercise decision map
The option is most valuable when it gives the charterer a clean choice at the right time.
| Market condition at option date | Best charterer action | Reason | Risk to check |
|---|---|---|---|
| Ship value above option price | Exercise | Charterer captures built-in equity and fleet control. | Financing availability and transfer mechanics. |
| Ship value near option price | Reprice or negotiate | Option may still matter if replacement tonnage is scarce. | Drydock timing, emissions file, and alternative ship cost. |
| Ship value below option price | Walk or renegotiate | Buying would lock in overpayment unless strategic value is high. | Redelivery cost and contract penalties. |
| High freight market and scarce tonnage | Exercise early | Ownership may protect earnings and cargo programs. | Whether early exercise carries make-whole cost. |
| Weak market but strong customer need | Compare replacement cost | The asset may still be worth buying if it is hard to replace. | Whether customer value exceeds market overpayment. |
Before signing a bareboat charter with a purchase option, build a one-page option memo. Include expected value at exercise, option price, implied financing rate, alternative loan cost, capex to reach exercise, emissions obligations, redelivery cost, and the walk-away case.
Final read for owners, charterers and lenders
A ship purchase option inside a bareboat charter is not just a future yes-or-no decision. It is a priced piece of the deal. The charterer may be buying upside, capital flexibility, and fleet control. The owner or financier may be selling residual-value optionality in exchange for hire and a target return. The option is worth the most when the exercise price is favorable, the vessel is hard to replace, the implied financing rate is attractive, and walking away remains genuinely possible if the market turns.
