From the designers..........


Conceived from the outset as an IRC specialist, the Botin 41 by McConaghy is a direct response to the revival of the Admiral’s Cup and the growing demand for optimized platforms within the AC2 Class, capped at a maximum TCC of 1.282.

The design brief is clear: Deliver a yacht capable of winning under IRC across both coastal and offshore formats, while maintaining a cost discipline to ensure accessibility for serious owner driver campaigns.

The new design needs to cope with a typical Fastnet Race in heavy conditions. Pure Engineering is considering these extreme load cases and adding strength over the minimum ISO requirements.
From the ergonomics and crew operation side, we have benefited from the recent experience in the 2025 Admiral’s Cup to fine tune the freeboard height, cockpit volume, overall watertightness and interior volume. The deck layout and running rigging systems are being designed to maximize performance and trimming tuneability, while minimizing through deck holes to avoid water ingress.

A new hull concept is currently being developed, more oriented towards fast offshore racing but keeping in mind that these boats will also compete in plenty of inshore windward leeward events. These sometimes conflicting requirements are being evaluated, and we are using our experience and Race Modelling / performance prediction software to place the boat in the right spot of the design space. The hull shape is being designed considering fitting a stern interceptor and benefiting from the experience of multiple of our grand prix designs fitting them since 2023.

The appendage package decision is wide open and under evaluation:

· Single vs twin rudder / i.e upwind efficiency vs fast reaching and downwind performance.
· High Lift upwind fins vs low drag reaching fins


Water ballast is a hot topic for the 41’ design, as the rating increase is substantial. The system is also relatively heavy for this size of boat, and also the added cost and complexity need to be considered. On the other hand, it allows for a much lighter boat which translates to speed in the right conditions.
We will make the final decision with each owner and speed team, as their input is fundamental.

This will be our fourth 41’ design since 2012 for McConaghy, together with Pure Engineering and Ancasta Race Boats, and all have been extremely successful in the worldwide Grand Prix circuits.
We will build on that experience to come up with a design which is a step forward compared to the current fleet, and it’s an exciting challenge ahead.

Machinery

All hardware fitted to the new Botin Cup 41 has been carefully considered around a blend of performance, reliability and most notably waterproofing.

Where function or control is increased measurably, the systems have bend added to the new design, but finding a balance of what makes the boat go faster vs what looks right, is where we are laser focused in order to control costs.
The base boat price we consider to be a high level machine, capable of winning, but owner input is welcomed to truly turn these boats into something extra special for their needs and how each team intends on sailing the boat.
