Naish is launching two new wingfoil foils: the Siren and the Excalibur. The two foil series are designed to cater for different requirements in the wingfoil sector: the Siren series features a medium aspect ratio of between 8.2 and 8.5, whilst the Excalibur range has a high aspect ratio of 10.2. The Siren series comprises four sizes ranging from 600 to 1,200 square centimetres, whilst the Excalibur range offers five variants ranging from 544 to 1,344 square centimetres.
Both series utilise the new Alpha connection system, which is designed to increase the rigidity of the connection between the front wing and the fuselage by 30 per cent compared with the previous Legacy system. The design features a larger cross-section and, depending on the size, two or three M8 bolts. The system allows for the fitting of larger high-aspect-ratio foils without the need for a specialised fuselage.
Siren for freestyle and waves
The Siren series combines a medium aspect ratio with a highly domed profile and a pronounced sweep at the leading edge. This design is intended to prevent stall and improve manoeuvrability in critical situations. The smaller sizes, 600 and 800, are aimed at freestyle and wave riders looking to push the limits. The larger versions, 1,000 and 1,200, focus on stability and low-end performance for advanced riders. Naish recommends combining it with S-Series stabilisers for maximum manoeuvrability. Those seeking greater efficiency can opt for the E-Series stabiliser range. The 600 model weighs 0.55 kilograms with a wingspan of 71.4 centimetres; the largest version, with 1,200 square centimetres, has a wingspan of 100 centimetres and weighs 1.26 kilograms.
Excalibur with a high-aspect design
The Excalibur series replaces the model Jet HA and features a constant aspect ratio of 10.2 across all sizes. The manufacturer claims that the highly cambered profile and high-modulus carbon construction improve glide performance and are designed to delay stall. A pronounced dihedral sweep at the wing tips is designed to prevent turbulence and improve manoeuvrability. The smallest version, with a surface area of 544 square centimetres, weighs 0.55 kilograms and has a wingspan of 74.5 centimetres; the largest model, with a surface area of 1,344 square centimetres, has a wingspan of 117 centimetres and weighs 1.35 kilograms, according to Naish. Naish recommends the E-Series Stabilisers for maximum speed and glide performance, whilst the S-Series are said to offer a more ‘surf-like’ character with greater manoeuvrability.
Alpha Aluminium Fuselage System
The new Alpha Alu Fuselage remains compatible with the existing Mini-Tuttle connection between the mast and the fuselage. The high-quality aluminium construction retains its rigidity and reliability, whilst the Alpha connection system – using two or three M8 bolts depending on the foil size – is designed to create a 30 per cent stiffer connection. The fully integrated stabiliser mounting is carried out from below, which simplifies assembly. All bolts are located on one side. The manufacturer claims that the revised fuselage shape reduces drag by 45 per cent compared to the legacy system. The modular three-component system allows the use of Excalibur and Siren front wings, as well as E-Series and S-Series back wings. Older wings are not compatible. The 57-centimetre-long fuselage weighs 0.67 kilograms, whilst the 64-centimetre version weighs 0.75 kilograms. The shorter version offers greater manoeuvrability, whilst the longer version provides greater stability.
