41' Offshore High Performance IRC
The BR41 Offshore is a new, high-performance IRC designed by BRYD. Designed around lower crew numbers from double handed up to a fully crewed compliment of six, the BR41 offshore unites the high-performance GP yacht attributes with the evolution and advances of the systems utilised in the open offshore classes.
Optimised for IRC/ORC offshore racing with a high form stability, low VCG, lightweight hull design combined with a refined sail package and systems, BR41 provides a potent platform to attack the major offshore regattas for class and overall wins.

Deck Layout & Philosophy
As the highest performance IRC/ORC shorthanded option for offshore events currently available, development of the highly ergonomic cockpit and lightweight deck systems configuration has been at the forefront of the design ethos. This human centred optimised approach enables maximised crew performance with huge effort taken towards the conservation of energy, enabling continuity of human performance when it really matters.
The BR41 supports a duel pit layout incorporating 2 x 50st performer primary winch systems with spinlock XXC, XTR clutches and XTX soft clutches for reef systems, with lines lead direct to the mast step through interior tunnels with tack lines and jib control systems exiting forward. For optimum headsail control, transverse track systems have been integrated enabling maximum control of both J1 and staysail J2 systems, with J1 sheet lead though an XTR for ease of cross leading and manoeuvres.
Runners lead forward in close proximity to the main sail controls, enabling ease of control in both short-handed and fully crewed conditions. The full winch package includes 6 harken performers which are optimally positioned to enable multifunctional operation. Each sail system can be held on clutches for spinnaker peels, cross leads, furling or just redundancy.
All sail control systems are externally lead to minimise water ingress, in keeping with the offshore human efficiency ethos, with helm and pit areas encapsulated within lightweight composite fairings deflecting whitewater away, maximising crew ability to push in heavy conditions.

The BR41 boasts a powerful and refined sail configuration for IRC and ORC, with options for hanked and furled foresail setups and multipurpose furled J3/staysails enables high functionality and the ability to change gears and optimise to the conditions instantaneously. The mainsail supports 2 single line reef systems, with options for lazy jack in tune with the conditions and racecourse format.
Downwind sail options comprise of multiple variants including masthead top down furling A sails, fractional A5 and mast head codezeros. For the rig setup, a 2 spreader keel stepped spar has been developed in a divergence from the offshore open yacht setup, maximising the performance gains in ability to fully tune your setup to the conditions.
Interior Layout & Systems Design
The BR41 supports a spartan racing yacht interior with a navigation station situated on the mast bulkhead enabling quick access to the navigation tools, with screens fully visible thought the companionway hatch.
The galley is situated on the port side supporting options for gas hob or jet boil utilities with supply’s stowage. Berths are constituted of 3x carbon fibre pipecots per side. A 30hp Yanmar sail drive engine is situated beneath the companionway steps/lightweight engine cover. The head is positioned forward of the masthead BHD on the port side.

The performance package for the BR41 has been meticulously developed by BRYD and Partners utilising advance numerical modelling techniques in development of the fully optimised configuration. Hull forms and appendages have been designed and optimised using in-house developed software in generation of fully parameterised hull forms for systematic morph assessment.
This coupled with the use of numerical modelling techniques, including the use of neural networks, enables efficient in-depth quantitative analysis of velocity prediction results from large numbers of hull form and appendage configurations attained from RANSE computational fluid dynamic simulations. The rigorous approach provides a refined optimised design to take on the world class offshore sailing regattas.
The BR41 structural design has been refined to achieve an extremely lightweight but robust platform, capable of meeting the most rigorous demands of performance offshore racing crews and conditions. Design to ISO CAT A and classified under GL, and optimised, utilising advance composite engineering tools such as CLT and NASTRAN FEA analysis.
The BR41 is constructed utilising hi-end prepreg glass fibre cloths and reinforcements with m-form cored construction from female tooling. Maximizing strength and stiffness whilst achieving an incredibly light structure to ensure the highest possible ballast ratio. Supplied with a fabricated steel fin with foam core fore/aft fairings further echoes the commitment to supreme performance. Going further with twin carbon rudders and bowsprit produced in pre-preg carbon fibre cured under four atmospheres of pressure within one of two autoclaves at the forefront of composite technology. With the yacht produced from female tooling, finishing weight is kept for the absolute minimum with a multitude of finishing options in Awlgrip Awlcraf paint systems.
