About this tender

Whitmarsh 6.2m SOLAS - what we know.

The Whitmarsh 6.2m SOLAS is the rescue-coded version of the yard's ST625 hull. Whitmarsh has been building UK superyacht tenders out of a small operation on the south coast for around fifteen years, and the SOLAS variant takes the same hand-laid GRP deep-V stepped hull and rebuilds it to satisfy the SOLAS rescue boat standard. That means equipment fit-out, structural detail, stability margin and presentation at code inspection are all worked into the build sheet rather than bolted on.

On a commercially-coded yacht above twenty-four metres, you need a SOLAS-compliant rescue boat in the garage. The Whitmarsh 6.2m SOLAS is one of the smaller-yard British options, sitting alongside the Cobra 6.2m SOLAS and competing with the Williams SOLAS 625 on a brief that prioritises hull quality and customisation over volume-builder polish. Console folds down for garage clearance, hull is built to take serious sea, and the equipment package is specified to the captain's flag state requirements.

Highlights

Built for the work.

The four details we'd point out first to a captain who hasn't seen one on the water yet.

01

ST625 hull, SOLAS specification

The base hull is the same hand-laid GRP deep-V stepped form Whitmarsh uses on the standard ST625, reinforced with Divinycell foam. The SOLAS version layers in the structural detailing and equipment fit-out required to present the boat at SOLAS code inspection. Yard size is small, and the build is run as a specification project rather than off a stock list.

02

Folding console, garage-friendly

The console folds down to a stowed height around 1.25m, which is the line most tender garages on yachts in the thirty-five to fifty metre bracket are cut to. For owners refitting a yacht where the SOLAS slot was pencilled in at low height, the ST625 SOLAS is often the boat that drops in without garage rework.

03

British yard, hands-on build

Whitmarsh runs a small UK operation rather than a production line. Console layout, helm seating, lifting geometry, electronics package, hypalon collar profile and the SOLAS equipment fit-out are all worked through with the captain at order stage. Lead times are longer than a stock builder, and the result is a tender that presents at code inspection without a punch list.

04

Sized for the typical SOLAS slot

At 6.5m LOA and 2.45m beam, the ST625 SOLAS sits in the bracket most commercially-coded yachts in the forty to fifty-five metre range carry. Lifting points, garage cradle and presentation at delivery are all engineered at the build stage so the tender is ready for first inspection at handover.

Questions, answered

Before you enquire.

How does the Whitmarsh 6.2m SOLAS differ from the standard ST625?
Same base hull, different build specification. The standard ST625 is a multi-role yacht tender at CE Category C with up to ten passengers. The SOLAS variant is built to the SOLAS rescue boat code, with the structural detail, stability margin and equipment fit-out required to satisfy a code inspection, and presented at delivery for SOLAS sign-off. Different paperwork and a different price.
What is the lead time on a Whitmarsh 6.2m SOLAS?
Whitmarsh is a small yard that builds to specification. Lead time depends on slot availability and the level of customisation on the build sheet, but it is materially longer than a Williams or a Ribeye out of stock configuration. We recommend opening the conversation with the yard at least nine to twelve months ahead of when the tender is needed in the garage.
Will it fit alongside a limousine in the same garage?
Often yes, depending on garage geometry. The folding console keeps stowed height inside 1.25m, and the 2.45m beam is consistent with most twin-stow garage layouts on yachts in the forty-plus metre bracket. We will work through the cradle layout with the captain or the shipyard at order stage to confirm the geometry.
Can the Whitmarsh 6.2m SOLAS double as a guest tender?
It is built primarily as a rescue boat and the equipment fit-out reflects that. It can be specified with upholstery and trim that allows occasional guest use in calm water, but if the brief is for a presentable owner-and-guest tender we would recommend the standard ST625 as a separate boat or look at a different builder. Doubling roles often compromises both.

The yard

Whitmarsh

Chichester, UK

Whitmarsh High Performance Ribs is a British builder operating from waterside premises at Northshore Shipyard, Chichester Harbour, on the south coast of England. The yard is a deliberately low-volume operation - founder James Whitmarsh brings over 35 years of experience in performance boat construction, offshore powerboat racing, and superyacht new-build and warranty work, and that background shapes every hull the company produces.

The range runs from 6.25m to 11.5m and divides into three clear families: the ST superyacht tender series (ST65, ST73, ST105, ST115, ST625, ST725, ST925), the SL SOLAS rescue and safety line, and the RS sport series (RS7, RS11), plus the custom C115 limousine build. The ST115 is the current flagship - an 11.5m platform rated to 1,200 hp drawing on a proven open-ocean racing hull, capable of over 60 knots. Hull and deck laminates are engineered using GRP and Divinycell foam core, optimised for the minimum weight-to-strength ratio; inboard and outboard configurations are both offered across the tender series.

What brings programmes back to Whitmarsh is the build philosophy: every boat is individually specified to complement the mothership, with bespoke finishes, upholstery detail, and a deep-V stepped hull design developed for genuine offshore sea-keeping. The yard also covers full custom projects and tender refit. We work with Whitmarsh on beach landers, SOLAS tenders, and guest RIBs; the price point holds up well against European volume builders at a meaningfully smaller production run.
