Crew & Working Tenders

Crew & Working Tenders for superyacht programmes. Independent reference for owners, captains, and build managers.

A crew or working tender is the boat that does the unglamorous work nobody photographs: provisioning runs to the marina, laundry collection from the dockside service, crew rotation between yacht and shore, fuelling logistics, and the daily grind of keeping the mothership operational. It is the tender that earns its keep on the running cost line, not the marketing brochure.

This page covers what makes a working tender different to a guest tender, the spec patterns that work, and the builders who serve the segment.

What separates a working tender from a guest tender

The brief is different and so is the boat. Working tenders are specified for:

  1. Cargo capacity over guest comfort. Open or partially-covered cockpit, deck-mounted tie-down points, washdown-tolerant surfaces, no soft upholstery to spoil.
  2. Hours and durability. A working tender will run two to four times the annual hours of a guest tender. Build standard has to reflect that, particularly the engine duty cycle and the drive choice.
  3. Crew operability. Helm position designed for a single crew member to handle the boat with five tonnes of provisioning aboard, in a marina, in 25 knots. That means good visibility, simple controls, and a deck layout that does not need a second pair of hands.
  4. Wash-and-go finish. Painted or gelcoat hull, GRP floor, vinyl or no upholstery, drains that work, hose-down tolerance everywhere.

Most guest-tender builders sell a "working" or "crew" version of their main hull with these changes built in. Some yards specialise in workboat-format tenders for the segment.

Sizes and formats

The mainstream brackets:

  • 5 to 7m, jet RIB or outboard centre console. Provisioning, crew shuttle to a beach club, ferry runs of one or two crew at a time. Build cost 60,000 to 200,000 EUR.
  • 7 to 9m, outboard or sterndrive open boat with a cargo well aft and bench seating forward. The mainstream working-tender size. Build cost 200,000 to 500,000 EUR.
  • 9 to 12m, often with a small enclosed wheelhouse for crew weather protection in long runs. Approaches a small workboat in capability. Build cost 500,000 EUR to 1.2m EUR.

Above 12m the asset usually doubles as a fast crew transfer boat or a backup chase boat and the spec changes accordingly. See chase boats for the larger end.

Propulsion

Three configurations dominate:

  • Twin outboard, easy to service, easy to swap, dominant on 6 to 9m boats. Mercury, Yamaha, Suzuki are the main brands.
  • Single or twin sterndrive, more efficient at cruise, common on 9 to 12m boats. Volvo Penta D4 or D6 with DPI or DPS drives.
  • Twin waterjet, where shallow-draft beach approach is part of the duty cycle, or where an exposed prop is unacceptable around swimmers and crew loading from the water.

Inboard shaft-drive is rare on working tenders below 11m because the running gear protrudes and gets damaged in close-quarters work.

Builders

The working-tender market overlaps heavily with the RIB and small commercial workboat market. Names that come up:

  • Williams Jet Tenders (UK), the dominant jet-RIB builder, working variants of the Sportjet and Dieseljet platforms
  • Ribeye (UK), a strong RIB workboat builder
  • Highfield (China/Hong Kong), affordable aluminium-collared RIBs
  • AB Inflatables, Zodiac Milpro, Sillinger for fully-inflatable working tenders
  • Goldfish (Norway), durable monohull workboats in 7 to 12m range
  • Tornado Boats (Denmark), purpose-built working RIBs
  • Pascoe International and Compass Tenders for higher-spec working variants alongside their guest-tender ranges

For most superyacht programmes the working tender is the builder's standard model with a stripped interior and an upgraded engine package. Bespoke is rare in this segment.

Garage and stowage

Working tenders tend to be smaller than guest tenders and easier to stow. Common patterns:

  • Aft-deck cradle stow with a deck crane for launch and recovery
  • Davit stow on the transom, particularly for sub-7m RIBs
  • Garage stow alongside the guest tender on multi-tender garages
  • Shadow-vessel stow for programmes that have outgrown the mothership garage and run a dedicated support vessel

The crew tender is the one most likely to live on the davits because it gets used most often and needs the fastest launch cycle.

What gets specified

The conversation with the builder usually covers:

  1. Bow door or roller for fender and line handling
  2. Reinforced rubbing strake and corner pads for marina-knock tolerance
  3. Cargo tie-down ring pattern in the cockpit deck
  4. Crew bench with grab rails, no soft upholstery
  5. Diesel transfer pump or fuel-bag tie-downs for fuelling runs
  6. Saltwater washdown pump and freshwater rinse outlet
  7. VHF, AIS receiver, and AIS transmit if the operating area requires
  8. Survival gear stowage (lifejackets x crew complement plus 25 percent, smoke flares, throw line, first aid)
  9. Tow point both bow and stern, rated and certified
  10. Hour meter and fuel totaliser, with maintenance log integration if the yacht runs a CMMS

The detail that catches working-tender programmes out is fuel transfer. A working tender that does provisioning and crew runs will burn 2,000 to 4,000 litres per season above its own consumption, fetching diesel for jet skis, the chase boat, and other thirsty assets. The diesel-transfer rig has to be specified and the safety case documented.

Operating cost

Working tenders run 400 to 800 hours per season against 150 to 300 for a guest tender. The cost line moves accordingly. Annual operating budget for a 9m sterndrive working tender on a Mediterranean charter programme:

  • Fuel, 600 hours at 35 litres/hour at 1.20 EUR/litre: 25,000 EUR
  • Engine and drive servicing (250-hour and 500-hour cycles): 12,000 EUR
  • Wear (props, anodes, fenders, lines, bottom paint): 6,000 EUR
  • Insurance: 5,000 to 9,000 EUR
  • Berthing or tender-park: 4,000 to 12,000 EUR

Total typically 50,000 to 70,000 EUR. See tender maintenance for the full schedule.
