2 Very original and interesting concept from HERU SAILS (double profile) with Heru mast
2 Heru Sails (Italy) https://herusails.com/2019/
Developped by Nico Huguet and Giulio Ivianni.
Very high building quality.
1 (bue/red) and 2 (yellow blue red) cambers (on lowest battens) and very original spacer system where you can adjust your thickness profile. The extrados and intrados difference can be customized very easily by changing the set of spacers. Then the power is customized and the air flows are very pure. With this system, the rotation of the profile is very soft (no pressure on the mast). I deliver a set of spacers and the corresponding 100% carbon mast (light) from which the sails where designed. Both are 9.5 m².
It is possible to remove the spacer to retrieve a more flat sail for stronger wind. It works very well.
Very cheap price : 600€ for the 2 sails and the mast.
