RIB Builders Compared

Williams, Pirelli, SACS, Pascoe, Brig, Ribco. Who builds what, and which yard fits which programme.

Published

Most superyacht RIB briefs end up on a shortlist of seven or eight yards. Each one has a clear lane: the brief that fits one yard rarely fits another. This page covers what the recurring names build and where each one earns its keep.

Williams Jet Tenders (UK)

The volume player. Williams's DieselJet line dominates the 4.5 to 7.5m bracket on production yachts in the 30 to 60m range. The format is consistent: jet drive, single-piece moulded GRP hull, Hypalon collar, garage-friendly geometry. Lead times 4 to 8 months on standard configurations.

Best for: any programme that wants a known-good guest RIB without bespoke specification. Less interesting if the brief calls for a unique layout, a non-standard propulsion choice, or a heavily-personalised finish.

Models we see most: DieselJet 565, 625, 745.

Pirelli (Italy, TecnoRib)

The fashion-forward option in the segment. Pirelli's Speedboat range pairs Italian styling with high-performance hulls; the recurring brief is owner-driven. Sizes from 9.6m to 18m. Lead times 8 to 14 months, longer for customised paint and trim packages.

Best for: programmes where the tender doubles as a personal-use sport boat, where the aesthetic is part of the brief, and where the owner wants to put their name on the boat.

Models we see most: Pirelli 35, 42, 50.

SACS (Italy)

The wide-range builder. SACS makes everything from 6m crew RIBs to 18m sport RIBs and the Strider chase boat line that crosses over with the chase boat segment. Distinguished by the Italian engineering approach (heavy attention to hull-collar geometry) and a willingness to do real customisation rather than option-package customisation.

Best for: bespoke briefs in the 8 to 14m bracket where the owner cares about boat-handling and seakeeping more than the badge.

Models we see most: SACS Strider 13, Rebel 47, Rebel 55.

Pascoe International (UK)

The dual-purpose specialist. Pascoe builds RIBs that are also rescue boats, also limousines, also working tenders. Strong on SOLAS coding (see the SOLAS tenders overview) and on the high-spec yacht-side end of the working RIB segment.

Best for: programmes where the RIB needs to do more than one job (e.g., daily working tender plus SOLAS rescue duty), and where the build budget supports a custom specification.

Models we see most: Pascoe SY 8500, SY 9500, custom limo-RIB hybrids.

Brig (Ukraine / Poland)

The price-per-metre leader in the 4 to 9m bracket. Brig's Eagle and Falcon ranges are the volume answer when the brief is "competent guest RIB at a defensible price." Polyurethane-coated fabrics, proper hull engineering, factory-fit Mercury or Yamaha outboards.

Best for: programmes where the RIB is a working asset with a 5 to 7 year horizon and the owner does not need bespoke specification.

Models we see most: Eagle 6.7, Falcon Tender 450 / 545.

Ribco (Greece) and Ribeye (UK)

Two more names that recur. Ribco builds aluminium-hulled RIBs (uncommon material for the segment) with a focus on high speed and mid-range pricing. Ribeye builds the Tornado and Argon ranges in the UK; aimed squarely at the production-yacht working-tender market.

How to shortlist

The brief variables that drive the right yard:

  1. Size band. Sub-7m: Williams, Brig, AB. 7 to 12m: SACS, Pirelli, Williams large. 12m+: SACS, Pirelli, Pascoe, custom.
  2. Use mix. Working tender: Williams, Brig. Owner sport: Pirelli, SACS large. SOLAS or rescue: Pascoe, Cobra, Whitmarsh. Bespoke: Pascoe, SACS, Compass.
  3. Budget envelope. Production cost-conscious: Brig, Ribco. Mid-market: Williams, SACS. Premium: Pirelli, Pascoe, Compass.
  4. Lead time. Inside 6 months: Williams stock or Brig. 6 to 12 months: most others. 12 to 24 months: Pirelli custom, Pascoe custom.

When a brief is unclear we run all four variables, narrow to two or three yards, then move to a comparative spec exercise. See the tender buying process for how that unfolds.

Which RIB builder fits a standard guest tender on a 40m production yacht?
Williams Jet Tenders, in most cases. The DieselJet line dominates the 4.5 to 7.5m bracket on production yachts in the 30 to 60m range, and the format is consistent: jet drive, single-piece moulded GRP hull, Hypalon collar, garage-friendly geometry. The models we see most are the DieselJet 565, 625 and 745. Williams is less interesting if your brief calls for a unique layout, a non-standard propulsion choice or a heavily-personalised finish - that work belongs with SACS or Pascoe.
How long are RIB lead times, and who can deliver inside six months?
Inside six months means Williams stock or Brig. Williams runs 4 to 8 months on standard configurations; most other yards sit in the 6 to 12 month band. Pirelli quotes 8 to 14 months, longer for customised paint and trim packages, and both Pirelli custom and Pascoe custom work can stretch to 12 to 24 months. Lead time is one of the four brief variables worth testing early, because it removes yards from a shortlist faster than budget does.
Who builds a RIB that can also serve as a SOLAS rescue boat?
Pascoe International is the dual-purpose specialist here, with Cobra and Whitmarsh also on the SOLAS and rescue list. Pascoe builds RIBs that double as rescue boats, limousines and working tenders, and is strong on SOLAS coding and on the high-spec yacht-side end of the working RIB segment. The models we see most are the SY 8500, SY 9500 and custom limo-RIB hybrids. It suits programmes where the RIB does more than one job and the build budget supports a custom specification.
What is the cost-conscious choice for a working guest RIB?
Brig is the price-per-metre leader in the 4 to 9m bracket, with Ribco the other name on the cost-conscious list. The Eagle and Falcon ranges are the volume answer when the brief is a competent guest RIB at a defensible price: polyurethane-coated fabrics, proper hull engineering, and factory-fit Mercury or Yamaha outboards. We see the Eagle 6.7 and Falcon Tender 450 and 545 most often. It suits a working asset on a 5 to 7 year horizon where bespoke specification is not needed.
How do I narrow seven or eight yards down to a real shortlist?
Run four variables: size band, use mix, budget envelope and lead time. Sub-7m points to Williams, Brig or AB; 7 to 12m to SACS, Pirelli or Williams large; 12m and above to SACS, Pirelli, Pascoe or custom. Owner sport use favours Pirelli and large SACS; premium budgets bring in Pirelli, Pascoe and Compass. When a brief is unclear we run all four, narrow to two or three yards, then move to a comparative spec exercise.
