What Tender Refit and Maintenance Covers
The term refit is used loosely in this industry, and that looseness creates budget surprises. We split the work into four tiers, because each tier has a different cost profile, a different delivery timeline, and a different answer to the question of whether a replacement hull would be more rational.
Tier 1: Routine maintenance. Annual service items - engine oil and impeller changes, battery replacement, antifouling, upholstery inspection, bilge pump test, trailer or lifting-point inspection. Most captains manage this in-house or through the yard that handles the mothership's annual haul-out. Cost is predictable; the work rarely surfaces structural surprises.
Tier 2: Cosmetic refresh. Gel coat cut and polish or repaint, new upholstery sets, re-varnished timber trim, new canvas. This is the work that brings a five-year-old tender back to a presentable standard without touching the structure or the driveline. Lead time is typically two to six weeks depending on upholstery and paint schedules.
Tier 3: Mechanical and systems refit. Engine replacement or rebuild, fuel-system overhaul, rewiring, new helm electronics, upgraded audio. This tier requires a professional yard with the correct engine agency relationships and, in the case of repowering, a sign-off from the original builder or an independent naval architect to confirm that the new driveline does not alter the vessel's stability or classification.
Tier 4: Structural refit. Osmotic blister repair, transom replacement, hull-stringer rebuild, sponson strip and re-bond on RIBs, keel-stepped mast refit on sailing tenders. This is the tier where the refit-versus-replace question becomes most pointed. A structural repair on a fibreglass hull that has been poorly maintained can cost more than the vessel's current market value.
For captains and project managers, the practical starting point is a condition survey carried out by an independent marine surveyor with specific small-craft experience. The survey report gives you a written scope, a prioritised defect list, and a document you can use to obtain competitive quotes from yards. Without it, yard quotes are based on assumptions and tend to escalate.
The Key Decisions
Refit or Replace?
This is the question that recurs most often in our briefs, and the honest answer depends on three variables: the structural condition of the hull, the availability of a replacement that matches your programme, and the timeline pressure from the owner's schedule.
A tender that is structurally sound but cosmetically tired is almost always worth refitting. The hull has been proven in your programme; you know its handling characteristics; the crew are familiar with it. A cosmetic and mechanical refresh at Tier 2 or Tier 3 will deliver a vessel that performs identically to new at a fraction of the replacement cost.
A tender with a compromised transom, delaminated hull sections, or a RIB sponson that has lost adhesion is a different calculation. Structural remediation on a fibreglass GRP hull requires skilled laminating work, and the repaired area will never be lighter than the original layup - which matters if the tender is weight-sensitive for its davit or garage. If the repair cost exceeds 40 to 50 percent of a comparable new-build price, we would normally recommend at least pricing a replacement before committing to the refit.
The timeline variable is underrated. A full structural refit at a competent yard takes three to five months. A new tender from a yard with available build slots can sometimes be delivered faster, and you have a vessel under full manufacturer warranty from day one. We cover replacement options, including current build slots and delivery windows, in the tenders hub.
Which Yard for the Work?
The refit market for superyacht tenders is less consolidated than the new-build market. Specialist RIB yards, GRP repair shops attached to large marina complexes, and the service arms of the original manufacturers all operate in this space. The criteria we use when recommending a yard are straightforward: direct experience with tenders in the 5.0m to 14.0m range, documented capability for the specific work required (structural laminating is not the same skill set as cosmetic refinishing), and a project management structure that gives you weekly written updates rather than phone calls.
For Tier 3 and Tier 4 work specifically, we also look for yards that carry product liability insurance for repowering work and that have a named project manager rather than a general service foreman. Budget overruns on tender refits are almost always traceable to scope creep that was not documented and priced at the outset.
Budget Benchmarks
These figures are indicative; actual costs depend heavily on the vessel's condition, the yard's location, and the specification of replacement parts.
- Tier 1 routine maintenance: 1,500 to 4,000 EUR per season for a single outboard tender under 6.5m.
- Tier 2 cosmetic refresh: 8,000 to 25,000 EUR for a mid-range RIB with full upholstery replacement and gel coat refinish.
- Tier 3 mechanical refit with engine replacement: 20,000 to 80,000 EUR depending on engine count and specification.
- Tier 4 structural refit: project-dependent; obtain a surveyor's report and three competitive quotes before committing a budget.
The Survey: Why It Comes First
A pre-refit condition survey is not an optional extra for larger projects. It is the document that defines the scope. Without a formal survey, yards quote on visual inspection, and visual inspection misses osmotic blisters behind the antifouling, core degradation in the transom, and wiring faults inside conduit runs. The survey fee - typically 600 to 1,200 EUR for a tender in the 7.0m to 12.0m range - is recovered many times over in avoided scope variations.
The surveyor you commission for a pre-refit assessment should be independent of the yard carrying out the work. This is standard practice for any vessel survey and it is particularly important for tenders, where the refit market is small enough that commercial relationships between surveyors and yards can create conflicts of interest.
Where to Start
If you are working through a refit brief for the first time, or returning to this question after a season that surfaced more defects than expected, the most useful starting point depends on what stage you are at.
If you are still deciding whether to refit or replace, the tenders hub gives you a current view of what is available at new-build, including lead times and pricing bands across the key size categories from 3.5m to 14.0m. Pricing a replacement is not a commitment; it is the data point that makes the refit decision rational rather than habitual.
If you have decided to refit and need a scope, commission an independent condition survey first. Use the survey report to brief three yards on the same written scope. Compare their quotes line by line, not as a single bottom-line number.
If you are managing an ongoing maintenance programme across multiple tenders on a large vessel, a written maintenance schedule tied to engine hours and calendar dates is the tool that prevents Tier 1 items from becoming Tier 3 problems. We can help you build that schedule as part of a broader fleet management brief.
The tender refit and maintenance topic intersects with several other areas we cover in detail. Classification and survey requirements for tenders operating in specific cruising areas, the structural and certification implications of repowering, and the question of what specification a replacement hull should carry to match your programme - these are all addressed in the reference guides linked from the tenders hub.
Talk to Us
We work with owners, captains, and project managers at every stage of the tender lifecycle - from first specification through new-build procurement, refit scoping, and disposal. If you have a refit brief that needs an independent view, send us the surveyor's report and a summary of your programme requirements. We will review the scope, cross-check it against yard pricing we have seen for comparable work, and come back to you within 48 hours with a written assessment.
If you do not yet have a surveyor's report and want a recommendation for an independent surveyor with specific small-craft tender experience in your cruising region, that is also something we can assist with at no cost. The brief does not need to be fully formed. A photograph of the defect and a note on what season the vessel needs to be back in service is enough to start a useful conversation.
Reach us through the contact form or directly via the project management enquiry route. We do not charge for initial scope reviews, and we do not have commercial relationships with the yards we recommend - our only interest is a refit that delivers the outcome your programme requires.
