International Moth

At Maguire Boats we produce the Exocet International Moth. We have worked closely with designer Kevin Ellway and top UK moth sailors to produce and supply a great new boat.

This work continues as we develop upgrades that can be easily retro fitted to your Exocet, keeping the boats up to date with the latest developments.

The Exocet, from Maguire Boats, represents the latest high performance Moth, which has culminated in innovative refinements in both hull and foil design that have achieved notable improvements in performance as well as their ease of use.
These have emanated from extensive computer modelling, the application of precision CNC tooling, careful material selection, and an exacting attention to construction detail and material layout, resulting in a high quality product that is stiff and robust. 

We have a world beating design and we need to stay at the leading edge of this. This does increase our costs. Our easy and accessible design helps with performance at all levels. Our first class build provides performance and reliability. This has lead to a strong second hand values. We are committed to ongoing R&D so the boat remains ahead of the field. We offer full product support with readily availability of spares and support for all Exocets built. We offer Exocet racing support at all the major events to keep you on the water.
If you are interested in a build slot, please get in contact for an estimate.

Boat Developments and Updates
Current developments:

New wand system
The Exocet is renowned for its superior handling qualities and ease of use. You can’t sail fast ifyou don’t have control. For 2015 we have improved the control even farther by adding a new design wand control system. This allows greater control with less gearing which gives more speed in choppy conditions.

Aerodynamic fairing
To augment the lowered rig, we have developed a fairing to clip over the wing compression struts. The fairing results in a small increase in sail drive force upwind. For optimal effect, the fairing should be used in conjunction with the new aero-mesh trampoline set. The first fairing has been built and is being evaluated, while we see there are small gains so far we need to constantly balance these against cost/ weight/ usability and practicalities. So currently this is not available as a production item as its still in developmental stage. We will realise details when we know more.

Moth sails and spars
Exocet sailors Mike Lennon, Chris Rashley and myself have been working hard on developing Moth sails that are fast both upwind and down. The sails are the culmination of aerodynamic design, flying shape analysis, and expert sailmaking utilising the latest materials and construction techniques. We are pleased to announce that 2 sails, based on these pre-production prototypes, will be available in early 2015 from Lennon Sails. The Xply has the advantage of uniform stretch in all directions which gives good gust response. The membrane sail is a little lighter and more should last longer, but the advanced construction comes at an increased price. The sails are available for lowered and standard rigged boats. The sails are designed to be used with CTech med 37mm masts, but are also compatible with the CST Elite 4 mast.Both of these sails can be ordered through Maguire Boats as part of the package.

Designers notes:

The new Exocet HX2 foils from Maguire Boats designed by Ellway Aero - Hydrodynamic Design

The Exocet International Moth now has a choice of 2 foil sets; the HX1 and HX2.
All Exocet foils are scientifically designed and developed using both 2D and 3D CFD (computational fluid dynamic) modelling coupled to a detailed VPP (velocity prediction program). The CFD models predict the lift and drag characteristics of the foils whilst the VPP is used to evaluate their performance in the Exocet Moth around a race course for differing rider weights in various wind and sea states. A final design is only reached after many iterations of design have been evaluated over a virtual race course with no further overall gain in performance.

The HX1 foil package is designed to perform over a widest possible range of conditions from marginal foiling to fresh to frightening and for sailors in the weight range 75 to 90kg. These foils get you foiling exceptionally early and have excellent glide to enhance foil tacking and to allow the sailor to soak deep downwind. Upwind you can choose your mode from very high to low and very fast. The foil sections and small overall area allow high downwind speeds.  These foils have already won both UK National and European Championships and also hold the outright UK Moth speed record of 31.7kts.
The new HX2 foil package is designed for maximum performance in winds of over an 11kt minimum speed. These foils are intended to be used by heavier sailors as a medium to high wind foil set, but can be used as all round foils for the lighter sailor. On the water, you will still lift out earlier than most non Exocet Moths. Once up and foiling you will still retain the glide and easy foil tacking and control for w
hich the Exocet is renowned, but you will have higher speeds in bow down mode upwind and especially offwind.
Compared with the HX1, the HX2 foils slightly trade early lift out for a higher top speed – you can’t have b
oth! Winds are rarely constant and can be unpredictable. There is, therefore, an overlap in the performance envelopes for the HX1 and HX2 foils. This allows the HX2 foil to perform well even in conditions outside of their design optimum.

Ellway Aero-Hydrodynamic Design
Races are rarely won solely on the basis of top speed, but hinge on minimising the time spent going slowly around the racetrack. The Exocet has been designed not only for high speeds, but also to minimise the time off the foils – she foils very early and has the glide to foil tack and gybe smoothly. Downwind, the Exocet is truly a missile, but is still very controllable and easy to sail in chop.
The Exocet represents the culmination of many thousands of hours CFD analysis of both the hull/foil hydrodynamics and the hull’s aerodynamics, combined with practical experience and elite sailor feedback. The smooth, rounded lines of the hull give a smooth lift out, and prevent it from catching in chop whilst also reducing windage. The foils and control system allow you to fly high and fast safely.
Maguire Boats has built the Exocet to the exacting standards demanded by the design. The hull, wings and foils are all very stiff. This allows drive from the rig and dynamic input from the rider to be converted directly into controllable speed.
