WASZP - Hull

The hull is designed with a hollow nose area to cater for the intended sailor weight range: 40 kg to 100 kg. The heavier sailor can bury the nose without creating extra drag while the lighter sailor does not lose waterline length. The very strong low riding performance helps the transition to getting on the foils.


WASZP - hull front

The forward curvature allows the wand connection to be brought forward for better response in waves. It also provides greater volume forward when bearing away to reduce accidental burying.

WASZP - hull stern

The stern is more voluminous to help in low speed manoeuvres and tacking that are most likely to result the stern sinking and coming off the foils.

It also enables the sailor to go aft to put the rudder up and down.


McConaghy - WASZP builders


The first licensed builder of the WASZP will be the renowned McConaghy Boats team (builder of the Mach2).

McConaghy - WASZP Hull mold

CNC machine milled moulds and tightly controlled manufacturing systems are used to ensure uniformity in tolerance, hull stiffness, finish and weight in line with strict one design principles.

McConaghy - WASZP Hull mold

WASZP will be a manufacturer controlled class using a Builders Construction Manual and will ultimately be subject to ISAF approved manufacturing control systems.


WASZP - Split hull

The hull is built with an infused epoxy system using Soric core to give a bullet-proof shell that will not dent with a hammer blow. Stiffness is obtained from the organic curves of the hull along an extensive framing system.

The centre seam enables 100% positive fixing of all internal frames and a bullet-proof join.

The frames will interlock via a tongue and groove system when the two halves are sealed.

The nose area (front few cm’s) is made from a soft compound for impact resistance.


WASZP - Hull Fittings

The fittings and control systems are a combination of custom design or best of breed from our friends at Harken or Ronstan or custom-built in-house.


An integrated mount for your GPS is included.



WASZP - Wing Tramps

To deliver the promise of foiling for beginners through to advanced racers the orientation of the wings of the WASZP needed to be flexible to change the amount of stability provided to the sailor.

In addition, to overcome the challenge of storage somehow the width of the WASZP needed to be significantly reduced when in the boat park or at home.

The Solution - the WASZP Hinged Wing System

WASZP - Wing Tube Connector

By articulating the wings on the inner deck in combination with an adjustment system at the outer gunwhale.

WASZP - Wing Blocks

The orientation can be changed quickly and easily changing the supplied wing supports.

A pin system securely locks the wings into their chosen mode.

WASZP - Wing Tubes

The wings tubes are 6061 aluminium tube with high strength plastic connectors.

WASZP - Wing Tramp Track

The WASZP tramps slot into tracks built into the hull.

WASZP - Wing Bladder

The tramps feature an integrated low drag flotation bladder that delivers positive buoyancy to provide a highly stable platform.

WASZP - Wing Tramp Pocket

Tramps include a forward storage pocket and integrated holders for drink bottles in easy reach to the rear of the tramps.


Extensive design work was undertaken to develop foil sections that maximised all round performance with early lift-off and control through a wide wind range.


WASZP - Vertical Foil

The vertical sections have come from proven low ventilation sections used on the Mach2.

WASZP - Horizontal Foil

The horizontals are a hybrid of high speed sections proven in the Mach2 and low speed, high tolerance sections used in the latest low wind Mach2 foils.

WASZP - Foils

The centreboard and rudder verticals and the horizontal foils of the WASZP are made from 6061-T6 aluminium.


Aluminium was seen as the only choice for the WASZP after experience in building more than 2,000 composite foils we realised that there was too much skilled workmanship required that meant inconsistency in foil production and finish.

With the WASZP our overriding mission was to be 101% consistent to enable racing by sailor merit rather than tweaking.

6061-T6 was chosen because it is the strongest marine compatible grade (with higher tensile aluminium’s being too susceptible to corrosion). It is also more durable and able to withstand greater wear and tear.


WASZP - Foils Down
WASZP - Foils Up


Both the centre and rudder foils are fully retractable meaning launching is easy and safe.


WASZP - Foil Joiner

A titanium joiner provides the load bearing strength for the interface between the horizontal and vertical.

WASZP - Wand Control

The main foil has an integrated flap controlled by a simple and robust mechanical sensor system driven by a fibreglass rod wand.


WASZP - Wand Control

The foil control system of the WASZP is born from many years experimentation on the Moth combining adjustability with simplified ease of use.

WASZP - Rudder box

Hard anodised aluminium is utilised for the rudder box and tiller. A custom tiller extension made from aluminium with non slip covering completes the rudder assembly.

WASZP - Foil Bag

And we want you to look after your foils so padded covers are included with all new WASZP’s.



Because the aluminium extrusions are continuous sections, creative thinking was required with wing tip solutions to best match the performance gains of a tapered foil.

A range of alternatives have been developed for testing.

WASZP -End Cap 2
WASZP -End Cap 3




WASZP - Final End Cap

The final design of the wing tips.

A massive amount of work went into resolving the final design including extensive CFD (computational fluid dynamics) analysis and testing on various wing tip and winglet versions.

The final main foil wing tip choice is a lot more conventional with tiny winglets and a short taper from the end of the aluminium – about 130mm of wing tip.

With the rear foil it’s very similar, except no winglets.

WASZP - Final End Cap



Optimising ease of rigging, simple tuning and effective performance across a wide wind range was the brief for the WASZP rig.

In addition, allowing for the foils to remain in place on shore meant a normal boom height was out of the question.

Finally, removing the potential dangers of a low boom and potential injury for crashing into stays meant a complete rethink was required.




The result – an unstayed, high performance sail with a wishbone boom that does not require a boom vang.


WASZP - Rig End Boom

The sail is end boom sheeted with mainsheet and outhaul running forward through an integrated pocket built into the foot of the sail. The mainsheet is then led back to a  block on the centreline.

WASZP - Rig Controls

All controls for Cunningham (downhaul) and foot tensioning (outhaul) terminate at the base of the mast support area for easy reach.



The WASZP sails are designed and built by KA Sail, a world leader in high performance Moth and windsurf sails.

The KA MSL series has dominated world and national championship podiums for the past decade.

The new KA MSL 16.5 took 1st, 2nd, 3rd at the 2015 Moth World Championships.

That makes it 10 of the last 11 Worlds won with KA Sails.

WASZP - Sail bag

The sails will be built over a 3D mould to ensure maximum consistency.

Three sail sizes are available to cater for sailor weight and experience.

The sails will rig on a two piece mast.


All WASZP sails feature a highly tuneable configuration.

The aluminium WASZP boom fits all sail sizes and attaches simply to the mast with an integrated fitting.
