About Whitmarsh
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.

SOLAS Tender Compliance
A SOLAS rescue tender is type-approved life-saving equipment, mandatory on yachts of 500 GT and over in commercial service. This guide explains what the LSA Code requires, which builders hold current type approvals, and how the choice drives garage and davit design.
ReadThe Complete Guide to Buying a Superyacht Tender
Most tender purchases go wrong in the brief, not the build. This guide walks the buying process end to end, brief first, garage envelope second, propulsion third, yard shortlist fourth, contract fifth, the way we run it for owners.
ReadDavit Systems and Launch/Recovery for Tenders
The davit is the part of the tender programme nobody thinks about until it fails. This guide explains the launch-and-recovery options, the SWL and cost that drive them, and why the geometry is locked at yacht-concept stage before the tender is chosen.
ReadTender Garage Sizing: Matching Tender to Mothership
The tender garage is the most expensive box on the yacht to get wrong, once built, stretching it means cutting structure. This guide works backwards from the tender envelope through the seven dimensions that actually decide which boat fits.
