A 62-foot motor yacht sells for $1.85 million. The listing broker signs a co-brokerage agreement with the buyer's broker. The buyer wires a 10% deposit. Three weeks later, the sea trial reveals a delaminated keel cooler. The deal restructures. The closing date slips two quarters. Somewhere in that timeline, a real revenue event happened — and if the brokerage's books treat the deposit, the listing-side commission, and the eventual co-broker remit the same way they treat a Tuesday parts invoice from the service yard next door, the financial statements will tell a story that has very little to do with reality.
Yacht brokerage and marine service yards sit at the intersection of three accounting disciplines that rarely meet: trust-account fiduciary accounting borrowed from real estate, ASC 606 variable-consideration analysis borrowed from professional services, and heavy-equipment depreciation borrowed from construction. The operators who get this right run cleaner audits, sleep through state license renewals, and price their service labor against actual loaded cost. The ones who don't tend to discover the problem the same way: a Department of Business and Professional Regulation field audit, a co-broker dispute over an undisbursed deposit, or a tax bill that ignores the entire travel-lift bonus depreciation argument.
This guide walks through the moving parts that make marine industry bookkeeping different from every other small-business chart of accounts you've seen.
The Two Businesses Under One Roof
Most independent marine operations are not one business. They are two — sometimes three — companies sharing a parking lot, a sign, and an EIN. Pretending otherwise destroys margin visibility and breaks the audit trail.
Brokerage is a commission-revenue, low-asset, fiduciary-trust business. Inventory is rare except for trade-ins held briefly between sales. The dominant accounting events are listing agreements, deposit receipts into trust, closing disbursements, and co-broker remittances.
Service yard is a labor-and-parts, capital-intensive, hourly-billing business. Inventory turns matter. Technician utilization matters. Travel lift uptime matters. Revenue recognition follows work-order completion or milestone billing, not deposit timing.
Slip rental and storage is a real-estate-like recurring-revenue business. Customers pay monthly or seasonally for the right to keep their vessel in a specific location. Revenue is recognized ratably over the rental period; deferred revenue sits on the balance sheet until earned.
Set up three departments — or three subsidiaries — in your chart of accounts from day one. A single P&L that mixes a 70% gross margin commission stream with a 32% gross margin service department and an 88% gross margin slip rental will produce a blended number that is true in arithmetic and useless in practice.
Commission Revenue Under ASC 606: When Is It Earned?
A yacht listing agreement is a performance obligation in search of a transfer point. ASC 606 forces the question: when does the broker actually deliver the promised service?
The defensible answer for most yacht brokerage transactions is at closing, not at offer acceptance. The performance obligation is to procure a buyer who completes the purchase, not to procure an offer. Until title transfers and funds settle, the consideration is variable — the deal can fall through on a survey contingency, a financing failure, or a buyer's change of heart inside the rescission window.
This matters because it means signed-and-accepted offers are not revenue. They are pipeline. The journal entry at offer acceptance touches the trust account (Cash held in trust, debit; Customer deposits held in trust, credit) but does not touch revenue. Only at closing does the commission move from a contingent expectation to a recognized fee.
For co-brokered transactions — and roughly seven in ten brokerage sales involve a co-broker — the gross commission needs to be split before recognition. The selling-side commission belongs to the listing broker; the buying-side commission belongs to the cooperating broker. Both sides should book their portion as gross revenue if they have primary responsibility for delivering the service to their respective client, with co-broker remittance flowing as a contract-level allocation rather than a contra-revenue. The practical journal at closing for a 10% gross commission on a $1.85 million boat with a 50/50 co-brokerage split looks like a $92,500 gross revenue recognition on the listing side and the same on the cooperating side, with the closing escrow agent making the actual fund movements.
The Trust Account: Where Most Brokerages Get In Trouble
Florida's Chapter 326 — the statute that governs yacht and ship brokerage — requires that all funds received in connection with a sale, purchase, or exchange of a yacht be deposited in a trust account within three working days, kept separate from the operating account, and never commingled. California, New York, Connecticut, and Illinois carry similarly prescriptive regimes, and California's enforcement program has been active enough in recent years that operators in that state should treat trust account hygiene as a license-protection issue, not an accounting nicety.
Three rules govern the trust account on a daily basis:
One: the trust ledger total must always equal the trust bank balance. Always. The shortfall between the two — even a one-day shortfall caused by a posting delay — is the single most common finding in state audits. Reconcile daily, not monthly.
Two: each open deposit needs its own client sub-ledger. When the state shows up, they will ask for a per-customer ledger showing the deposit, any disbursements, and the running balance. A single aggregated trust ledger with $4.2 million in pooled deposits and no per-deal subledger is a citation waiting to happen.
Three: three-way reconciliation is the standard. The bank statement, the trust ledger control account, and the sum of all client sub-ledgers must match. Any discrepancy gets investigated immediately, before the next deposit hits.
In bookkeeping terms, the trust account is a fiduciary asset and a fiduciary liability of equal magnitude on the broker's balance sheet — never revenue, never operating cash, never available for payroll. The day a brokerage borrows from its trust account to make payroll is the day its license is at risk. Build the chart of accounts so that the trust cash account and the customer deposits liability account are physically separated from operating accounts and so that no AP check run, no payroll run, and no owner draw can ever touch them.
The Service Yard: Where the Money Actually Comes From
For most multi-revenue marine operations, the service yard generates more bottom-line dollars than the brokerage in any given year. Brokerage commissions are lumpy and dependent on the macro yacht market; service revenue is steadier and tied to the installed base of boats that already need work.
Revenue recognition in the service yard follows the work order, not the deposit. A spring commissioning package with a 30% deposit collected in February and the work performed in April is deferred revenue at deposit time and recognized as revenue across April as labor is performed and parts are installed. A bottom-paint job that runs three days produces revenue on each of those three days, not on the day the invoice is sent.
Three areas reward careful setup:
Labor recovery and effective billing rate. Every technician hour has a fully loaded cost (wages + benefits + payroll taxes + workers' comp + a share of overhead). The yard's billed rate to the customer needs to recover that cost plus a target margin. Track effective billing rate as (invoiced labor revenue / billable hours worked) and compare it to the standard shop rate to surface unbilled time, courtesy adjustments, and warranty rework that's quietly eating margin.
Parts markup and inventory accuracy. Parts revenue is typically marked up 30–50% over cost. Inventory shrinkage, mispriced parts on work orders, and warranty-eligible parts billed to the customer instead of submitted to the manufacturer all suppress margin. Cycle counts beat year-end physical counts for keeping the inventory subledger honest.
Sublet work. When the yard subcontracts canvas, electronics, or rigging work to a specialist, that revenue and the corresponding cost pass through the yard's books. ASC 606 requires a principal-versus-agent analysis: if the yard takes pricing risk and primary customer responsibility, it's principal and books gross revenue; if it merely passes through a third-party invoice with a small handling fee, it's agent and books only the fee as revenue.
Capital Equipment: The Travel Lift Conversation
A 75-ton travel lift costs roughly $400,000 to $700,000 depending on configuration. A forklift rated for boat handling adds another $80,000 to $150,000. A trailer hauler for over-the-road moves runs $90,000 plus tractor. The boatyard build-out — concrete pads, electrical service pedestals, wash-down systems, paint sheds — adds six and sometimes seven figures more.
Section 179 expensing and bonus depreciation are the two main tools for accelerating the deduction on this equipment, and the math has shifted as bonus depreciation has phased down. For 2026 placements, bonus depreciation is at a lower percentage than the 100% rate that prevailed through 2022, so the planning conversation has moved away from "expense everything immediately" and toward more deliberate selection between Section 179 (which is capped and subject to taxable-income limits) and the remaining bonus tier.
Two adjacent moves deserve attention:
Cost segregation on the yard build-out. A real estate cost segregation study can reclassify portions of the build-out from 39-year nonresidential real property to 15-year qualified improvement property, 7-year personal property, or 5-year personal property. Electrical pedestals, wash-down systems, shore power upgrades, lighting tied to specific operations, and modular floating docks often qualify for shorter recovery periods. The study pays for itself on yards above roughly $1 million in capitalizable build-out.
Inland marine coverage on customer vessels. Boats sitting on jack stands or in the slings of the travel lift are customer property under your care, custody, and control. Standard commercial property policies typically exclude these — you need a marina operator's legal liability endorsement or inland marine coverage that names customer vessels. The premium is an operating expense; the coverage is the difference between a stable business and a single bad lift drop ending the company.
Documentation, Title, and the Federal Versus State Question
Yachts above five net tons can be documented with the U.S. Coast Guard rather than titled with a state. Documentation gives the vessel a national identity, simplifies international travel, and is required for certain commercial uses and for vessels financed by lenders that require Preferred Ship Mortgage filings.
For the broker, this matters at closing. A documented vessel transfers via a bill of sale recorded with the National Vessel Documentation Center; a state-titled vessel transfers via the state DMV-equivalent process. The closing checklist looks different. The escrow agent's role looks different. The transfer-tax exposure looks different — and several states have specific yacht sales and use tax rules with caps that are economically significant on transactions above roughly $300,000.
For the service yard, documentation matters because the vessel's official number, hailing port, and home port determine which state has tax nexus on the work performed. Yards that take in vessels documented in low-tax states for work performed in high-tax states need to understand their state's rules on materials versus labor sales taxability before assuming the customer's home-port jurisdiction governs.
Worker Classification: The 2024 DOL Rule Still Matters
Marine service yards lean heavily on specialized labor: riggers, fiberglass technicians, mechanics, canvas makers, painters. The temptation to classify these workers as 1099 independent contractors is strong — flexible scheduling, project-based work, specialized skills, the appearance of independence.
The 2024 Department of Labor final rule on independent contractor classification under the Fair Labor Standards Act restored a multi-factor economic-realities test that weighs control, opportunity for profit or loss, investment, skill, permanence, and integration into the business. State ABC tests in California, New Jersey, Massachusetts, and several other states are stricter still, presuming employee status absent affirmative proof on all three prongs.
The practical test for a marine yard: if the tech uses your tools, works exclusively at your yard, takes assignments from your service writer, gets paid by the hour rather than the job, and has done so for two years, the tech is almost certainly an employee regardless of what the engagement letter says. The cost of getting this wrong includes back wages, back FICA, back unemployment, penalties, and exposure to private wage-and-hour litigation that has accelerated in coastal states.
Bookkeeping as Operational Insight
Accurate financial records are not just a tax-time obligation for marine operators — they are the only way to know which department is actually profitable. A brokerage that doesn't separately track listing-side and selling-side commissions cannot tell you whether its listing inventory is moving or whether it's quietly becoming a buyer's brokerage. A service yard that lumps labor revenue and parts revenue together cannot tell you whether its technician utilization is the problem or whether its parts markup is the problem. A slip operation that doesn't track occupancy by month cannot price its seasonal contracts against actual demand.
Plain-text accounting — where every transaction is a human-readable text entry that can be reviewed, version-controlled, and queried with standard tools — fits the marine industry's operational rhythm unusually well. Seasonal businesses need to look at the same period across multiple years. Audit-prone businesses need a transaction trail that cannot be silently mutated. Multi-department businesses need a chart of accounts that can be sliced and re-sliced without rebuilding reports.
The KPIs That Actually Run the Business
A handful of metrics, watched monthly, tell you whether the operation is healthy:
- Listing-to-sale conversion rate — what percentage of listings sold in the period, by price band. Below 40% on the trailing twelve months suggests stale inventory or mispriced listings.
- Days on market — the median number of days a sold listing was active. Rising days-on-market is an early warning before listing volume drops.
- Co-brokerage participation rate — the share of closings involving a cooperating broker. Falling participation can signal MLS issues, relationship problems with peer brokerages, or a shift in the underlying buyer pool.
- Technician billable utilization — billed hours divided by paid hours. Healthy yards run 65–78%; below 55% means too many techs for the work, above 85% means burnout and unbilled time leaking out.
- Effective billing rate — invoiced labor revenue divided by billable hours. Compare to standard shop rate to surface leakage from courtesy discounts, warranty rework, and write-downs.
- Parts gross margin — parts revenue minus parts cost divided by parts revenue. Sub-30% means inventory shrinkage, mispricing, or unrecovered warranty parts are eating the margin.
- Slip occupancy rate — occupied slips divided by total slips, monthly. A seasonal yard with 95% summer occupancy and 30% winter occupancy needs different pricing and storage offers than one running steady year-round.
Pick four or five, watch them every month, and the brokerage and the yard stop being a black box.
