Lead Times and Delivery: Planning Your Tender Build

Tender lead times are the single most under-planned variable in superyacht projects. The mothership build manager works on a 24-month bar chart with monthly milestone reviews. The tender is treated as an accessory, slotted in late, and the slot is invariably tighter than the builder needs. The result, season after season, is yachts that launch without their primary tender, or with a stand-in, while the proper boat is finished after the owner's first guests have already come and gone.

This guide sets out the realistic timing for tender procurement in 2026, what drives the variability, and how to build a delivery plan that actually holds.

What "lead time" really means

Builders quote lead time as the gap between contract signature and delivery. That number is honest, but it is incomplete. A workable delivery plan has six distinct phases, and any of them can absorb weeks.

1. Specification and contract. Two to twelve weeks. Fastest for production open tenders on standard configurations; longest for custom limousine and chase platforms.
2. Builder slot allocation. Zero to twenty-six weeks. The wait between contract signature and the boat actually starting on the production line. Currently the binding constraint at the premium end of the market.
3. Build. Eight to forty weeks. Hull lay-up through systems installation through deck fit-out.
4. Pre-delivery commissioning. Two to six weeks. Engine commissioning, sea trials, snag list, paint cure.
5. Delivery and freight. One to twelve weeks. Truck across Europe, container across the Atlantic, ship-on-ship to a Pacific cruising ground.
6. Customs clearance and registration. One to eight weeks, depending on jurisdiction. See importing a tender into the EU and UK for the procedural detail.

Add it together and the working envelope for a quality limousine or chase tender ordered today, in May 2026, is 14 to 30 months from purchase order to operational delivery. For a stock open tender on a standard configuration, the envelope shrinks to 6 to 14 weeks.

The short version, by type, as 2026 working envelopes:

The 2026 picture: what the order books look like now

Tender builder backlogs softened from the 2022 peak but have not fully normalised, and they sit inside a still-tight wider market: the BOAT International Global Order Book reports yacht build slots stretching into 2028 and 2029, with buyers paying premiums to secure slots. Tenders are a shorter-cycle market than 24-month-plus yachts, but the same supply pressure shapes the position across the categories we track most closely:

• Production open and RIB tenders (Williams Jet Tenders, Sacs, Pirelli, Highfield in tender configuration). 8 to 16 weeks for in-stock or near-stock specifications. Custom paint or specific engine packages add 8 to 12 weeks.
• Premium production limousines (Wajer, Pascoe semi-custom range). 12 to 18 months. Order books are open into 2027 for most popular models.
• Custom limousines (Hodgdon, Vikal, Pascoe full custom). 18 to 30 months from concept signature, depending on yard load and design complexity.
• Beachlanders and SOLAS-rated rescue tenders (beachlanders, SOLAS rescue tenders). 14 to 22 months for a large custom unit; 8 to 14 months for adapted production hulls. This reconciles with the widely cited 8 to 12 month order-to-delivery figure for a standard configured SOLAS tender, per Superyacht Tenders; the longer envelopes here are for the larger bespoke units, and small 4.5 to 4.8 m outboard tenders can be ordered in roughly 4 to 8 weeks.
• Chase boats (under 16m). 12 to 24 months for custom; 4 to 10 months for stock platforms requiring outfit work. See chase-boat builders for category context.
• Electric and hybrid tenders (electric tenders). Variable; battery-supply chain remains the wildcard. 14 to 24 months is realistic.

These numbers are working envelopes, not promises. We update them quarterly in the journal.

What drives the variability

Three factors do most of the work in determining where any given build sits in the envelope.

Engine and drive supply

Diesel engines for marine applications run on long manufacturer queues. A custom chase boat with a triple V12 or quad V10 setup can be held for months waiting on engine delivery. Outboard supply has improved since 2023 but specific Mercury, Yamaha, and Suzuki configurations still have their own queues. Diesel-jet packages from Hamilton or Castoldi have their own lead times that the boat builder does not control.

Lock the engine order at contract signature, with serial numbers allocated, or accept that the build slot will stretch to whatever the engine supplier delivers.

Paint and coatings

A premium AwlGrip or Stoppani paint scheme is six to ten weeks of yard time, and it is sequential. The boat sits in the paint shed and nothing else can happen to it. Builders who run their own paint operations have more control; those who outsource it are at the mercy of a separate yard's calendar. Establish, before contract, who is doing the paint and what their slot looks like.

Specification stability

Owner-driven changes after the design freeze are the second largest source of slippage (after engine supply). A change to the seat layout at week 18 of a 32-week build can absorb four weeks. A change to the helm console electronics at week 24 can absorb six. Discipline on the specification freeze date is the single biggest thing the project manager can do to protect the schedule.

For a sense of how much of this can be controlled at the spec stage, see the tender specification guide and the tender buying process.

Building a delivery plan that holds

We work backwards from the operational date the owner needs the boat. For a yacht launching in May, the tender should be at the mothership four weeks before launch, to allow proper handover, davit testing, crew familiarisation, and any commissioning snags. From there, count back.

For a custom limousine landing at the mothership in early April:

• Tender at mothership for handover: April 1
• Freight from builder yard: February 15 to March 15 (truck across Europe; longer if intercontinental)
• Customs clearance: February 1 to February 15
• Sea trials and snag completion: January 15 to January 31
• Painted hull complete: mid-November
• Hull and structure complete: late August
• Build start: late February (previous year)
• Contract signature: July of the year before that

That is a 21-month critical path. Compress any single segment and the risk of late delivery rises sharply. Compress two and the boat will be late.

For a stock open tender to the same April 1 deadline, the path collapses to: contract January 15, build complete March 1, customs and freight to mid-March, handover by month-end. Twelve weeks.

Where stock and demonstrators help

A small but useful share of the market is met by stock boats and demonstrators. Builders periodically have hulls in inventory, either ordered for cancelled projects or built speculatively for boat shows. Pricing is often slightly above the equivalent custom order (because configuration is fixed), but delivery can be measured in weeks rather than years.

We track stock availability across new tenders and the active brokerage market at tenders for sale. For owners who need a boat for a 2026 season and have only weeks to work with, this is normally where the answer lies.

Coordinating with the mothership build

Most tender lateness is not the tender builder's fault. It is the mothership project manager scheduling the tender contract too late. The tender contract should be signed by the time the mothership's main systems contracts are placed, not after.

Three coordination points to enforce.

1. Garage geometry locked at tender contract. A change to the garage envelope after the tender is in build creates rework on both sides. Lock the dimensions, cross-reference them in both contracts, and treat them as fixed. See tender garage sizing for what that geometry actually involves.
2. Davit and launch-system specification jointly signed off. The tender supplier and the davit supplier should be in the same room (or the same call) before either contract is finalised. The launch interface is the most common source of delivery-week surprises.
3. Delivery window aligned with mothership delivery. A tender that arrives six weeks before the mothership launches is fine. A tender that arrives six weeks after is a problem the project manager has to manage in front of the owner.

Insurance, registration, and crew training during the lead time

The lead time is also the window for the surrounding operational work. None of it has to wait for delivery.

• Insurance binding can be quoted on the contract specification and bound subject to delivery. See tender insurance, survey and sea trials.
• Crew training (RYA Powerboat Level 2, RYA Tender Operator) can be completed before the boat arrives. See tender crew training and licensing.
• Registration paperwork can be prepared in advance with the chosen flag-state agent.
• Customs broker selection and engagement should happen at the start of the build, not the day the boat ships.

A six-month head start on the operational layer is normal for well-run projects. A scramble at the end is a failure of planning.

What to do if the project is already late

A few things, in order.

1. Get an honest reforecast from the builder. Not a hopeful date; a probability-weighted date with a critical-path explanation.
2. Identify the binding constraint. Engines, paint, or specification rework. Each has different mitigations.
3. Consider stock alternatives. A stock or demonstrator from the same builder, or a comparable from another, may close the gap. Treat this as a parallel track, not an alternative.
4. Plan the bridging period. Charter a similar tender for the early-season weeks if the operational programme cannot wait. Several Mediterranean operators run season-long tender charters.
5. Communicate early. Owners accept honest delays better than they accept silence.
